#intra-disorder holder

[possessed-pack]

Being an intra-disorder holder is an absolute pain because on one hand, I have Symptoms. On the other hand, these Symptoms won't usually be understood by medical professionals as exclusive to me, and if they are, then they'd assume I'm an issue or a "problem alter" because of the way I see things or would be put off by my lack of empathy. I can't be seen as struggling by those who could potentially help me because it would cause more issues to me and my system than it would fix.

I don't want the body diagnosed either because we don't all have the disorder (and getting a DX would be detrimental to our rights even if we did). It's just not how it works or what I want--my SYSTEM doesn't have these symptoms, I do.

And in a lot of system spaces, the precedent is set that you can hold symptoms, but only of disorders the body has. A lot of this, in my opinion, comes from spaces trying to defend themselves from anti-systems saying symptom-holders make no biological sense and are "cringe" or whatever, with people reacting like "oh no we have the disorder, this person just feels it more!"--which is also a valid experience, but I don't see much of a difference in how it would make sense or not compared to disorders the body doesn't have.

There's so much shit about it. It sometimes feels like it should just be kept quiet. But I don't want it to go ignored either. It's hard to find space where I can talk as someone with Symptoms without fear of being accused of whatever is cool to harrass people for that day.

But I'm not going to be quiet, because if others deserve support groups and/or people who understand them, then I sure as hell do too. It's a strange middleground that I'm stuck in, but I'm going to try and be a little more open about it because if there's one thing I'm good at, it's spite.

Intra-Disordered

We don't do coining posts often, if at all, but this one applies to some of us and we figured we'd tentatively share.

Intra-Disordered: A person within a system with the experiences of having a disorder/symptom the body does not have or is not known to have.

Intra as in "within", referring to within a headmate.

This can be the result of trauma, isolated symptoms caused by trauma-holding, symptoms a headmate has in source, psychosis, or other reasons. This can also include symptoms of a disorder the body has that are not experienced by others in the system, such as a system with autism collectively being okay with sounds of all types, but one of them is sound-sensitive.

To be used with sublabels if you prefer, such as intra-ADHD or intra-anxiety, and can also refer to specific symptoms, such as intra-hallucinations or intra-tics. If you'd like a headmate role-esque phrasing, intra-disorder holder is an alternative, which can be coupled with the sublabels such as intra-BPD holder.

This term is specifically to differentiate from bodily-disordered experiences while also having ways of easily phrasing disordered symptoms the body as a whole does not have, while keeping both validated. Similar in purpose to "exotrauma"--to acknowledge both experiences while they are similar, but separate, and both are deserving of support.

Introduction.

I am Cinnabar, a member of the @interstellarsystem. I use he/they pronouns and am demimale. I'm a noncanon Web + Desolation avatar sourced from The Magnus Archives--I don't remember meeting any canon individuals, but I'm fine with sourcemates regardless.

I'm not normally very social, but I don't mind people interacting--I just might take a while to get the energy to respond.

More under the cut.

Identity

We're a DID system, but we won't tolerate any exclusionism here. Systems of ALL origins are welcome--I won't put up with anti-endo shit, we're quoigenic and honestly I think origin labels lately seem to mainly serve as just a reason to hate more than anything constructive.

Anyway, all of us are alterhuman or nonhuman on some level. I don't consider myself to be human, or really of any particular species. I just am, now that I don't have The Web or The Desolation here to fuel me or choose my path.

I'm an intra-disorder holder of NPD and/or potentially ASPD, if you have an issue with that then you can leave. We also experience psychosis and are diagnosed with schizoaffective disorder--same rule as above, if you take issue, goodbye.

I consider myself terrorpunk, meaning I give literally 0 shits if you find me cringe or "evil" or whatever for any reason. Stay in your lane and I'll stay in mine.

DNI + Boundaries

I don't have a DNI, I'll just block as I please. I also doubt I'd read anyone elses--I shouldn't have to scroll through pinned posts or inaccessible carrds to look for your discourse opinions, just block me if you don't want me interacting.

Overall I won't tolerate any form of exclusionism--which result in guaranteed blocks--but that's pretty much a given.

[dentalinfotoday]

The world is moving from analogue to digital, and so are dentists. Technology has revolutionized the dental industry to optimize patient care and satisfaction. The latest advancements have made the time you spend in the dental chair more efficient, while making sure your absolute comfort is never compromised.

Dentistry is moving forward, and I’ve listed a few ways how:

1. Dental 3D Printing

As with many other fields of science and art, the potential applications of 3D printing technology are endless.

If you ever needed a restoration procedure done, the sequence might go as follows:

Your dentist takes an impression of your upper and lower arch

S/he sends that to the lab

You both wait for the lab to create the desired dental models

You will be asked to return when the final product has been delivered to your dentist

With the advent of 3D printing, this can all be done in one appointment.

If you happen to have a tech-savvy dentist, he or she will scan your mouth with an intra-oral scanner that is then presented as a 3D image on the computer. (1) The dentist will then digitally design the desired treatment and send this information to the 3D printer that brings it to life.

A 3D printer has many uses in the dental practice:

Inlays and onlays

Dental crowns

Bridges

Implants

Mouth guards and night guards

Full or partial dentures

Orthodontic appliances (e.g. Invisalign or other clear aligners)

Not only does this save you weeks of waiting for dental labs to finish your dental product, but it also provides you with more accurate results. And, let’s be honest, who doesn’t want to skip the lengthy manufacturing process?

Whereas traditional methods allows your dentist to fix any defects after the restoration has been placed in your mouth, this newer method allows him or her to adjust any faults digitally before going to print set-up. This optimizes both your time, your dentist’s time, and your overall healthcare.

2. Digital X-Rays

Radiographs, also known as X-rays, are an essential part of treatment. They are used to diagnose many oral health issues not visible to the naked eye. This includes cavities, periodontal (gum) disease, and root infections, to name a few.

Traditionally, you dentist or dental hygienist would have film in a plastic holder and place it in the area of your mouth they would like to view. There are intra-oral and extra-oral x-rays that target different parts of the head. After capturing the images, they will be processed and analyzed by your doctor.

Although traditional x-rays have been a great diagnostic tool for many years and continue to be used for their lower cost, they have their drawbacks:

Film-based X-rays must be processed, which takes time

Processing film requires chemicals that may be toxic and hard to dispose of

Film isn’t as sensitive to the x-ray beam as digital technology, meaning there’s more radiation output from the x-ray head to produce an image

Digital radiography uses digital sensors to replace the conventional film that dentists have depended on for so many years. The sensor is connected to the computer and when it receives the image, it is immediately displayed on the screen for viewing and analysis. (2) The result? A totally digital workflow, completed in seconds.

It may be more expensive to purchase for the dentist, but the benefits outweigh the initial costs:

No use of chemicals

Environmentally friendly

Faster processing, saving valuable time for you and your dentist

Image enhancement with computer software (with high resolution originals)

50-80% less radiation than film

Images stored in electronic patient records, and sent quickly to referring dentists or insurance companies

If you are concerned about the radiation of x-rays, we have answered a few of your questions here and here.

3. CBCT (Cone Beam)

The types of X-rays we use for diagnosis vary on a case-to-case basis, and in some instances, we need a little more information than what a regular dental x-ray provides us.

Cone beam computed tomography (CBCT) is used to create 3D images of your teeth, surrounding tissues, nerves, ligaments, and bone in the maxillofacial region (head, neck, face, jaws). Think of it as 3D scanners making a digital model of everything your dentist needs to see.

Your dentist will position you in the center of the beam, and the machine will rotate around you in a 360 degree fashion. The whole process takes about 20-40 seconds for a complete scan.

Here are a few reasons a dentist may need to use a CBCT for a better look at a patient’s mouth:

Endodontic surgery (root canals): Gives clinicians valuable information on vulnerable structures such as sinuses, missed canals, and nerve channels

Implant placements: Provides accurate placement of implants in bone and the position of the inferior alveolar nerve as it relates to the placement of implants to prevent nerve damage

Orthodontic work: High quality analysis for the correction of malocclusions and facial disproportion

Diagnosing TMJ

Detecting and measuring jaw tumors

The 3-D images the CBCT produces identifies about 40 percent more lesions (3). That’s why Dr. Burhenne suggests patients get cone beam scans every 5-10 years after a root canal to identify any problems that arise.

Due to a much higher radiation exposure than regular dental x-rays, however, it is only done in cases where the information provided for treatment planning outweighs the radiation risk. That’s why the FDA recommends cone beams not be the first route for dental imagery.

4. DIAGNOdent

Dental caries, or cavities, are one of the most prominent problems in oral health care. Traditionally, dentists diagnose cavities using bite-wing x-rays and a dental explorer. Most cavities occur on the pits and fissures of the tooth, but many go undetected by using traditional methods.

One study showed sensitivity (ability of a test to correctly identify those with a disease) and specificity (ability of a test to correctly identify those without the disease) values of 62% and 84% with the conventional method.

In other words, dentists correctly detected cavities 62% of the time, and correctly determined no cavities 84% of the time (4).

Our goal as dentists is to not only treat cavities accurately, but also to arrest and prevent them in their pre-cavitation stages before a potentially rapid spread of decay. With the introduction of instruments such as the DIAGNOdent pen, in conjunction with our traditional methods, we can do just that.

The laser fluorescence it emits allows us to detect cavitated lesions from non-cavitated lesions.

At the 655 wavelength the device operates, cavitated lesions result in higher scale readings, while non-cavitated lesions result in lower scale readings (4).

DIAGNOdent helps improve treatment in several ways:

Audio signal allows dentist to distinguish between different scale readings

Increases detection accuracy at earlier stages than traditional methods alone

More precise in identifying pit-and-fissure cavities and proximal cavities

Minimally invasive

Read more about how dentists are diagnosing cavities with lasers in another post.

5. Intra-Oral Scanner & Intra-Oral Camera

If you have ever needed restorative or aesthetic work done, you know that one of the first things your dentist or dental assistant does is take an impression.

You see them mixing several materials together to create a uniform consistency, transfer that to a tray, and insert it in your upper or lower arch. They hold the impression material down for a few minutes until it sets, and then remove it.

Most patients are very uncomfortable with this process due to the taste of the material, time it takes to set, and uncontrollable gag reflexes. Patient comfort, along with several other factors can affect the accuracy of a traditional impression due to:

Proper material preparation

Mixing material

Application technique

Setting time

These challenges can lead to improper margins and missed details, resulting in improper fitting of restorations as well as improper occlusion (bite). Digital dental impressions provide an alternative to these complications so that a patient’s teeth may be restored without as much discomfort.

Intraoral scanners are shaped like a pen and project a light source onto the area to be scanned, such as your upper and lower arches for instance (5). Your entire mouth anatomy is captured by imaging sensors and projected onto a computer.

This creates a 3D model of your teeth and surrounding tissues and allows your dentist to diagnose and treat you with increase accuracy and precision.

Some reasons why dentists are moving from traditional to digital impressions are:

Increased patient comfort (this is especially true for those who struggle with mouth breathing, as the airway isn’t blocked by a big tray of impression putty)

No gag reflex or pain

Time efficient

Improved quality and detail of impressions for better-fitting restorations

Reduction in technique sensitive errors

Eco-friendly solution that reduces the need for plastic and impression material

Increases communication and understanding between dentists and patients

The latest technology includes intra-oral cameras that allow your dentist to capture images from points during the scan to be enlarged. This provides a greater overall comfort for the patient, better diagnosis, and more efficient treatment planning.

6. TekScan

Your oral cavity is a complex system made up of muscles, bones, and ligaments. These must all be in harmony for you to talk, bite, and chew properly.

If one of these components is out of balance, it can lead to several problems such as:

Temporomandibular joint (TMJ) disorder

Headaches

Bruxism

Fractured teeth

Broken restorations

Tooth pain  

Gum disease

Traditionally, dentists check occlusion (the contact between teeth), with articulating paper. You will notice that your dentist will put this colored piece of paper between your teeth and ask you to bite down a few times. Your dentist will then diagnose these colored marks left on opposing teeth to check that they are contacting properly.

Articulating paper is also used to check if new restorations, such as fillings, inlays and onlays, crowns, and bridges are in proper occlusion with the rest of your dentition.

One study surveyed a group of 295 dentists, many of whom reported that they are “unable to reliably differentiate high and low occlusal force from looking at articulating paper marks.” The analysis from this study showed a sensitivity of 12.6% and specificity of 12.4%, which proves extremely low reliability and confidence using articulating paper as a diagnostic tool. (6)

TekScan offers a modernized solution to these issues. The TekScan device has an extremely thin sensor that is placed inside of your mouth, and just like with articulating paper, you are asked to bite down on it (2). A specialized software then displays your occlusion on a computer screen.

Here are a few things TekScan can do:

Detect biting time and force of bite

Show how occlusion is related to your TMJ

Identify what forces are causing trauma to your TMJ

Detect presence of any occlusal interferences

With this device, any of the guesswork involved in using articulating paper or other traditional methods is eliminated. Your dentist will be able to more accurately diagnose and correct any bite issues, optimizing your post-operative recovery.

7. The Wand

If you are someone who fears going to the dentist, it is probably because of one thing: injections.

Injections gives patients increased anxiety levels and discomfort. A needle can be very intimidating to some people, and the thought of getting one at the dentist’s office prevents patients from coming in altogether. The Wand offers a solution to that.

The Wand is an extremely thin needle that looks more like a pen than it does a needle. This automatically relaxes a patient that otherwise seems extremely anxious in the dental chair. A cartridge filled with local anesthetic is inserted into the Wand, and the delivery of the anesthetic is controlled by a computer (7).

The major benefits of the Wand include (7):

Single Tooth Anesthesia (his allows dentists to numb just one tooth rather than the entire lower jaw)

Three different delivery speeds (Slow, Fast, and Turbo) depending on the injection site

Reduces patient anxiety levels

Extremely thin needle that results in less pain upon injection

For those of you who are looking for other ways to manage your anxiety, we explore the benefits of taking CBD before coming to the clinic.

8. CAD/CAM

Computer-aided design and computer-aided manufacturing (CAD/CAM) is a computer software that is used to design and create prosthesis (8). A dental prosthesis is a dental appliance used to replace defects such as missing teeth or parts of intact teeth that need restoration.

Why are dentists shifting to CAD/CAM?

Faster fabrication

More precise fit

Increased predictability

Improved efficiency

How does CAD/CAM do all of this? With the help of an intra-oral scanner called CEREC, (CEramic REconstruction) that digitally transfers the information to the computer.

As previously mentioned, the source of digital light on the scanner scans the tooth in need of a restoration and all adjacent teeth that impact its function. The computer then uses this information to precisely calculate a 3D image of restoration for the tooth in question.

We use this creation of orthodontic models for several procedures, such as:

Inlays and Onlays

Crowns

Bridges

Dental implants

This all comes to life using the manufacturing part of the device, the CAM unit.

A specific material is placed in the milling unit, such as titanium, resins, glass ceramics, and zirconium oxide to name a few. The CAM unit mills the material to the precise structure created on the computer, bringing the image to life in a matter of minutes.

While it used to take several visits to the dentists for a restoration, CAD/CAM cuts that down to just one. The application of this technology are numerous and aids dentists in achieving more accurate clinical results.

Revolutionizing Dentistry through Technology

From 3-D printing to on-site milling machines, the world of dentistry has been completely revolutionized by modern technology on the dental market.

Dentists can now provide higher quality treatment faster than traditional methods. They are able to be more accurate and precise in their treatment, preventing future complications. Leading-edge equipment gives dentists more confidence and predictability, which results in improved healthcare for their patients.

It is more than a trend; It is the future of the field, and it is here now.

DNI/Stances:

We don't have a DNI and may or may not notice yours. Generally we do look for them so we don't interact with people who would cause issues for us but if it requires too much searching and/or reading we won't go digging just to reblog or like something. We believe in the power of the block button and won't take offense if it's used against us for any reason.

We're of the opinion that it's unfair to expect everyone else to go digging through hard to read blog themes and text walls no matter how inaccessible just to be allowed to reblog something when the block button is also right there. Bigots and such won't be stopped by a DNI if they're coming at you with the intention of causing harm so we personally just don't see a point in having one for ourselves and prefer to block whenever we want.

The latest technology includes intra-oral cameras that allow your dentist to capture images from points during the scan to be enlarged. This provides a greater overall comfort for the patient, better diagnosis, and more efficient treatment planning.

6. TekScan

Your oral cavity is a complex system made up of muscles, bones, and ligaments. These must all be in harmony for you to talk, bite, and chew properly.

If one of these components is out of balance, it can lead to several problems such as:

Temporomandibular joint (TMJ) disorder

Headaches

Bruxism

Fractured teeth

Broken restorations

Tooth pain  

Gum disease

Traditionally, dentists check occlusion (the contact between teeth), with articulating paper. You will notice that your dentist will put this colored piece of paper between your teeth and ask you to bite down a few times. Your dentist will then diagnose these colored marks left on opposing teeth to check that they are contacting properly.

(6)

TekScan offers a modernized solution to these issues. The TekScan device has an extremely thin sensor that is placed inside of your mouth, and just like with articulating paper, you are asked to bite down on it (2). A specialized software then displays your occlusion on a computer screen.

Here are a few things TekScan can do:

Detect biting time and force of bite

Show how occlusion is related to your TMJ

Identify what forces are causing trauma to your TMJ

Detect presence of any occlusal interferences

With this device, any of the guesswork involved in using articulating paper or other traditional methods is eliminated. Your dentist will be able to more accurately diagnose and correct any bite issues, optimizing your post-operative recovery.

7. The Wand

If you are someone who fears going to the dentist, it is probably because of one thing: injections.

Injections gives patients increased anxiety levels and discomfort. A needle can be very intimidating to some people, and the thought of getting one at the dentist’s office prevents patients from coming in altogether. The Wand offers a solution to that.

The Wand is an extremely thin needle that looks more like a pen than it does a needle. This automatically relaxes a patient that otherwise seems extremely anxious in the dental chair. A cartridge filled with local anesthetic is inserted into the Wand, and the delivery of the anesthetic is controlled by a computer (7).

The major benefits of the Wand include (7):

Single Tooth Anesthesia (his allows dentists to numb just one tooth rather than the entire lower jaw)

Three different delivery speeds (Slow, Fast, and Turbo) depending on the injection site

Reduces patient anxiety levels

Extremely thin needle that results in less pain upon injection

For those of you who are looking for other ways to manage your anxiety, we explore the benefits of taking CBD before coming to the clinic.

8. CAD/CAM

Computer-aided design and computer-aided manufacturing (CAD/CAM) is a computer software that is used to design and create prosthesis (8). A dental prosthesis is a dental appliance used to replace defects such as missing teeth or parts of intact teeth that need restoration.

Why are dentists shifting to CAD/CAM?

Faster fabrication

More precise fit

Increased predictability

Improved efficiency

How does CAD/CAM do all of this? With the help of an intra-oral scanner called CEREC, (CEramic REconstruction) that digitally transfers the information to the computer.

As previously mentioned, the source of digital light on the scanner scans the tooth in need of a restoration and all adjacent teeth that impact its function. The computer then uses this information to precisely calculate a 3D image of restoration for the tooth in question.

We use this creation of orthodontic models for several procedures, such as:

Inlays and Onlays

Crowns

Bridges

Dental implants

This all comes to life using the manufacturing part of the device, the CAM unit.

A specific material is placed in the milling unit, such as titanium, resins, glass ceramics, and zirconium oxide to name a few. The CAM unit mills the material to the precise structure created on the computer, bringing the image to life in a matter of minutes.

While it used to take several visits to the dentists for a restoration, CAD/CAM cuts that down to just one. The application of this technology are numerous and aids dentists in achieving more accurate clinical results.

Revolutionizing Dentistry through Technology

From 3-D printing to on-site milling machines, the world of dentistry has been completely revolutionized by modern technology on the dental market.

Dentists can now provide higher quality treatment faster than traditional methods. They are able to be more accurate and precise in their treatment, preventing future complications. Leading-edge equipment gives dentists more confidence and predictability, which results in improved healthcare for their patients.

It is more than a trend; It is the future of the field, and it is here now.

Orthodontics Collection

Orthodontics is a branch of dentistry that specializes in diagnosis, prevention and treatment of teeth and jaws that are positioned improperly when the mouth is closed (malocclusion), which results in an improper bite. The treatment also includes cosmetic dentistry which is controlling facial growth, shape and development of the jaw to improve the patient’s appearance.

Many of the instruments used for orthodontic treatment are used in conjunction with fixed and removable appliances. Before commencing orthodontic treatment on patients, all dental students should have the knowledge of these instruments and their uses.

Orthodontic appliances

There are two types of orthodontic appliances: fixed and removable.

Fixed orthodontic appliances

The most common devices used in orthodontics. They are used when precision is important.

Fixed orthodontic appliances include:

· Braces — consist of bands, wires and/or brackets. Bands are fixed tightly around the teeth and serve as anchors for the appliance, while brackets are most often connected to the front of the tooth. Arch wires are passed through the brackets and fixed to the bands. As the arch wire is tightened, tension is applied to the teeth, gradually moving them to their proper position.

· Special fixed appliances: To control tongue thrusting or thumb sucking, they are attached by bands to the teeth.

· Fixed space maintainers: If the child loses a milk tooth, a space maintainer is used to keep the space open between the two teeth at either side, until the permanent tooth erupts. A band is attached to one of the teeth next to the space, and a wire is extended to the other tooth.

Removable orthodontic appliances

These are typically used for treating minor problems, such as preventing thumb sucking or correcting slightly crooked teeth. They should only be taken out when cleaning, eating or flossing.

Removable appliances:

Headgear — A strap is tied around the back of the head, which is attached to a metal wire in the front. This slows down upper jaw growth, and holds the back teeth in position while the front teeth are pulled back.

2) Lip and cheek bumpers — specially made to keep the lips or cheeks away from the teeth and relieve them of the pressure exerted.

3) Aligners — an option to traditional braces for adults. Serial aligners are virtually unnoticeable and used by orthodontists to move teeth without metal wires and brackets. They can be removed when patients brush their teeth, eat or floss.

4) Removable retainers — these devices are worn on the roof of the mouth to stop the teeth from shifting back to their original positions. If modified, they can be used to prevent children from sucking their thumbs.

5) Removable space maintainers — these devices are made with an acrylic base that fits over the jaw and are an alternative to fixed space maintainers.

6) Palatal expander — an appliance designed to widen the arch of the upper jaw. It consists of a plastic plate that fits in the palate, with screws to exert pressure on the joints in the bones. This expands the roof of the mouth.

7) Splints (jaw repositioning appliances) — they are worn on either in the top or lower jaw and help train the jaw to close properly. Splints are commonly used for (temporomandibular joint disorder) TMJ syndrome.

The other essential orthodontic instruments required for an orthodontics procedure include:

Mirror — for visualization and retraction.

Separating Pliers — to stretch the separators for placement on the teeth.

Cotton Pliers — placement of cotton rolls for isolation, intra-oral retrieval of small objects.

Mathieu Plier — placement of elastomeric ligatures.

Howe Utility Pliers — hold arch-wires during placement and removal.

Bird Beak (139 Plier) — making bends in orthodontic wires.

Distal End Cutters — cutting and holding of the terminal end of a ligated arch-wire, intra orally.

Band Pusher — fitting and positioning an orthodontic band on a tooth.

Straight Probe — positioning of orthodontic brackets, removal of excess composite or elastomeric ligatures from around brackets.

Bite Stick — placing and seating orthodontic bands with the patient’s biting force.

Posterior Band Remover — removal of orthodontic bands on posterior teeth.

Band Burnisher — to adapt and contour an orthodontic band to fit the tooth.

Bracket Holder or Bracket Tweezer — to hold and place orthodontic brackets.

Cheek Retractor — to move the cheeks away from the teeth for visualization and isolation of the treatment area.

Plastic Filling Instrument — to place composite onto the mesh pad of an orthodontic bracket before bonding of the bracket.

Disorder Differences in Systemmates

Systemmates share the same brain, which often leads to the assumption that they're all affected the same by the brain itself. Its wiring, its abilities, and its disabilities. But symptom holders or those with intra-disorders are fairly common--at least in circles we run in--and they're not often talked about for fear of fakeclaiming or appearing ableist. We have headmates who are affected in all sorts of different ways by our disabilities. Some find things harder than others, while others actually find some tasks or symptoms easier to manage. It absolutely varies from headmate to headmate, which makes certain headmates better suited for fronting during certain times than others.

Merlin is more affected by our psychosis, particularly hallucinations, and xe tends to be more susceptible to paranoia. Mystery is a psychosis holder too, and has more positive symptoms like hallucinations than the rest of us, but is less affected negatively by it. It often hallucinates and falls into delusional thinking, but it's not really too bothered by it. So Mystery is a good choice for someone to front when we're having a psychotic episode. Sometimes, having Merlin cofront with Mystery makes it easier for Merlin to not be so susceptible to xyr symptoms.

I (Martin) have more obvious anxiety than the rest of us, and struggle much more in social situations. I'm much better at hyperfocusing on tasks, though. So I'm better suited for staying home and working on whatever the current project we have at the time, or keeping our to-do lists in check. Vince on the other hand is calm in most social situations that are more professional--so he's good for business meetings and such. In more casual conversation though, Vena and Merlin are much better at it and better suited to non-professional social groups.

Vince is an intra-NPD holder and also holds stronger symptoms of our BPD. He struggles immensely with percieved rejection, much more than the rest of us. But he also almost completely lacks empathy, which makes it much easier for him to be calm and logical in stressful situations. He finds it easier to help friends and those he cares about during stressful times because he's not weighed down by feeling their emotions--whereas the rest of us might break down from stress.

We talk a bit about mental disability differences in headmates more than those who differ physically. Somehow it seems more controvertial to mention that we have headmates that differ with physical symptoms while even in safe system spaces. It seems like most people (us somewhat included) mainly think of symptom holders as a mental disorder thing--a line of thinking we're trying to dispel. Headmates can have different disabilities and symptoms of all kinds, and it's not ableist or "harmful" to know that and speak about it. Headmates with different conditions to the body need to be recognised more.

Mike needed a cane in his memories and he absolutely needs our cane when he fronts more than the rest of us. He feels more at home and like himself having a cane by his side here, though, so it's good we already had one. I (Martin) need it more too--my joints are just more prone to pain. But our cane folds up nicely into our bag, so if we switch out in public, it's always with us just in case. Even if it's silly, we feel safer having a cane too--I mean, it's a metal pole. We're out as trans and clearly not your Regular Society Member, so it provides some feeling of safety to have.

Jayfeather was blind before, and since coming here he sure can see now, but he's much more light sensitive than the rest of us. The feeling of being able to see was nice at first, even if it was foreign, but sometimes he feels it's not worth the hassle. He needs to wear sunglasses when fronting because his eyes just end up hurting from even small amounts of light. Crowley is the same, except he wasn't blind in his memories--he just got used to always wearing sunglasses in his life to hide how his eyes looked, and needs them here now. They're both more prone to migraines due to this.

Merlin is more shaky on his feet than others who front often. His legs are digitigrade and in headspace he has his wings and tail to balance him there--but in the body, he doesn't have any of that. His legs are the wrong shape and he has no counterweight to his posture. Even with our cane, he's more prone to tripping than most.

Mystery was a godlike being that didn't need to eat human food, or any physical food at all. It often forgets that eating, sleeping and going to the bathroom are things the body needs to do, because it doesn't often feel the need to do them. That can be good if we're running low on food, or if we can't eat for a while such as before a medical procedure though, so it's useful in its own way. Mystery is also not used to using its hands for intricate things like tying shoelaces, as it's hands before we're longer, bigger, and mainly nonphysical. It didn't need to be intricate, so it's hard for it to do things others in here can.

There's so many more examples in our system. The thing is, there can be positives and negatives to any disorder, really--and headmates are no different with that. We don't necessarily assign headmates "roles" or "jobs" based on their symptoms or lack thereof, but for us to function better as a collective, people tend to gravitate toward doing certain things they know others can't. It's important for us to know how we differ with our disabilities, and work around them together as best we can.

Systemmates with different symptoms aren't uncommon, and they're not mocking disabled people, or lying for some benefit. I'd argue that for some systems with symptom holders or intra-disorder holders, it's increcibly important to know about how you differ and how to work together to be functional--whatever functional means for you.

[dentalinfotoday]

The world is moving from analogue to digital, and so are dentists. Technology has revolutionized the dental industry to optimize patient care and satisfaction. The latest advancements have made the time you spend in the dental chair more efficient, while making sure your absolute comfort is never compromised.

Dentistry is moving forward, and I’ve listed a few ways how:

1. Dental 3D Printing

As with many other fields of science and art, the potential applications of 3D printing technology are endless.

If you ever needed a restoration procedure done, the sequence might go as follows:

Your dentist takes an impression of your upper and lower arch

S/he sends that to the lab

You both wait for the lab to create the desired dental models

You will be asked to return when the final product has been delivered to your dentist

With the advent of 3D printing, this can all be done in one appointment.

If you happen to have a tech-savvy dentist, he or she will scan your mouth with an intra-oral scanner that is then presented as a 3D image on the computer. (1) The dentist will then digitally design the desired treatment and send this information to the 3D printer that brings it to life.

A 3D printer has many uses in the dental practice:

Inlays and onlays

Dental crowns

Bridges

Implants

Mouth guards and night guards

Full or partial dentures

Orthodontic appliances (e.g. Invisalign or other clear aligners)

Not only does this save you weeks of waiting for dental labs to finish your dental product, but it also provides you with more accurate results. And, let’s be honest, who doesn’t want to skip the lengthy manufacturing process?

Whereas traditional methods allows your dentist to fix any defects after the restoration has been placed in your mouth, this newer method allows him or her to adjust any faults digitally before going to print set-up. This optimizes both your time, your dentist’s time, and your overall healthcare.

2. Digital X-Rays

Radiographs, also known as X-rays, are an essential part of treatment. They are used to diagnose many oral health issues not visible to the naked eye. This includes cavities, periodontal (gum) disease, and root infections, to name a few.

Traditionally, you dentist or dental hygienist would have film in a plastic holder and place it in the area of your mouth they would like to view. There are intra-oral and extra-oral x-rays that target different parts of the head. After capturing the images, they will be processed and analyzed by your doctor.

Although traditional x-rays have been a great diagnostic tool for many years and continue to be used for their lower cost, they have their drawbacks:

Film-based X-rays must be processed, which takes time

Processing film requires chemicals that may be toxic and hard to dispose of

Film isn’t as sensitive to the x-ray beam as digital technology, meaning there’s more radiation output from the x-ray head to produce an image

Digital radiography uses digital sensors to replace the conventional film that dentists have depended on for so many years. The sensor is connected to the computer and when it receives the image, it is immediately displayed on the screen for viewing and analysis. (2) The result? A totally digital workflow, completed in seconds.

It may be more expensive to purchase for the dentist, but the benefits outweigh the initial costs:

No use of chemicals

Environmentally friendly

Faster processing, saving valuable time for you and your dentist

Image enhancement with computer software (with high resolution originals)

50-80% less radiation than film

Images stored in electronic patient records, and sent quickly to referring dentists or insurance companies

If you are concerned about the radiation of x-rays, we have answered a few of your questions here and here.

3. CBCT (Cone Beam)

The types of X-rays we use for diagnosis vary on a case-to-case basis, and in some instances, we need a little more information than what a regular dental x-ray provides us.

Cone beam computed tomography (CBCT) is used to create 3D images of your teeth, surrounding tissues, nerves, ligaments, and bone in the maxillofacial region (head, neck, face, jaws). Think of it as 3D scanners making a digital model of everything your dentist needs to see.

Your dentist will position you in the center of the beam, and the machine will rotate around you in a 360 degree fashion. The whole process takes about 20-40 seconds for a complete scan.

Here are a few reasons a dentist may need to use a CBCT for a better look at a patient’s mouth:

Endodontic surgery (root canals): Gives clinicians valuable information on vulnerable structures such as sinuses, missed canals, and nerve channels

Implant placements: Provides accurate placement of implants in bone and the position of the inferior alveolar nerve as it relates to the placement of implants to prevent nerve damage

Orthodontic work: High quality analysis for the correction of malocclusions and facial disproportion

Diagnosing TMJ

Detecting and measuring jaw tumors

The 3-D images the CBCT produces identifies about 40 percent more lesions (3). That’s why Dr. Burhenne suggests patients get cone beam scans every 5-10 years after a root canal to identify any problems that arise.

Due to a much higher radiation exposure than regular dental x-rays, however, it is only done in cases where the information provided for treatment planning outweighs the radiation risk. That’s why the FDA recommends cone beams not be the first route for dental imagery.

4. DIAGNOdent

Dental caries, or cavities, are one of the most prominent problems in oral health care. Traditionally, dentists diagnose cavities using bite-wing x-rays and a dental explorer. Most cavities occur on the pits and fissures of the tooth, but many go undetected by using traditional methods.

One study showed sensitivity (ability of a test to correctly identify those with a disease) and specificity (ability of a test to correctly identify those without the disease) values of 62% and 84% with the conventional method.

In other words, dentists correctly detected cavities 62% of the time, and correctly determined no cavities 84% of the time (4).

Our goal as dentists is to not only treat cavities accurately, but also to arrest and prevent them in their pre-cavitation stages before a potentially rapid spread of decay. With the introduction of instruments such as the DIAGNOdent pen, in conjunction with our traditional methods, we can do just that.

The laser fluorescence it emits allows us to detect cavitated lesions from non-cavitated lesions.

At the 655 wavelength the device operates, cavitated lesions result in higher scale readings, while non-cavitated lesions result in lower scale readings (4).

DIAGNOdent helps improve treatment in several ways:

Audio signal allows dentist to distinguish between different scale readings

Increases detection accuracy at earlier stages than traditional methods alone

More precise in identifying pit-and-fissure cavities and proximal cavities

Minimally invasive

Read more about how dentists are diagnosing cavities with lasers in another post.

5. Intra-Oral Scanner & Intra-Oral Camera

If you have ever needed restorative or aesthetic work done, you know that one of the first things your dentist or dental assistant does is take an impression.

You see them mixing several materials together to create a uniform consistency, transfer that to a tray, and insert it in your upper or lower arch. They hold the impression material down for a few minutes until it sets, and then remove it.

Most patients are very uncomfortable with this process due to the taste of the material, time it takes to set, and uncontrollable gag reflexes. Patient comfort, along with several other factors can affect the accuracy of a traditional impression due to:

Proper material preparation

Mixing material

Application technique

Setting time

These challenges can lead to improper margins and missed details, resulting in improper fitting of restorations as well as improper occlusion (bite). Digital dental impressions provide an alternative to these complications so that a patient’s teeth may be restored without as much discomfort.

Intraoral scanners are shaped like a pen and project a light source onto the area to be scanned, such as your upper and lower arches for instance (5). Your entire mouth anatomy is captured by imaging sensors and projected onto a computer.

This creates a 3D model of your teeth and surrounding tissues and allows your dentist to diagnose and treat you with increase accuracy and precision.

Some reasons why dentists are moving from traditional to digital impressions are:

Increased patient comfort (this is especially true for those who struggle with mouth breathing, as the airway isn’t blocked by a big tray of impression putty)

No gag reflex or pain

Time efficient

Improved quality and detail of impressions for better-fitting restorations

Reduction in technique sensitive errors

Eco-friendly solution that reduces the need for plastic and impression material

Increases communication and understanding between dentists and patients

The latest technology includes intra-oral cameras that allow your dentist to capture images from points during the scan to be enlarged. This provides a greater overall comfort for the patient, better diagnosis, and more efficient treatment planning.

6. TekScan

Your oral cavity is a complex system made up of muscles, bones, and ligaments. These must all be in harmony for you to talk, bite, and chew properly.

If one of these components is out of balance, it can lead to several problems such as:

Temporomandibular joint (TMJ) disorder

Headaches

Bruxism

Fractured teeth

Broken restorations

Tooth pain  

Gum disease

Traditionally, dentists check occlusion (the contact between teeth), with articulating paper. You will notice that your dentist will put this colored piece of paper between your teeth and ask you to bite down a few times. Your dentist will then diagnose these colored marks left on opposing teeth to check that they are contacting properly.

Articulating paper is also used to check if new restorations, such as fillings, inlays and onlays, crowns, and bridges are in proper occlusion with the rest of your dentition.

One study surveyed a group of 295 dentists, many of whom reported that they are “unable to reliably differentiate high and low occlusal force from looking at articulating paper marks.” The analysis from this study showed a sensitivity of 12.6% and specificity of 12.4%, which proves extremely low reliability and confidence using articulating paper as a diagnostic tool. (6)

TekScan offers a modernized solution to these issues. The TekScan device has an extremely thin sensor that is placed inside of your mouth, and just like with articulating paper, you are asked to bite down on it (2). A specialized software then displays your occlusion on a computer screen.

Here are a few things TekScan can do:

Detect biting time and force of bite

Show how occlusion is related to your TMJ

Identify what forces are causing trauma to your TMJ

Detect presence of any occlusal interferences

With this device, any of the guesswork involved in using articulating paper or other traditional methods is eliminated. Your dentist will be able to more accurately diagnose and correct any bite issues, optimizing your post-operative recovery.

7. The Wand

If you are someone who fears going to the dentist, it is probably because of one thing: injections.

Injections gives patients increased anxiety levels and discomfort. A needle can be very intimidating to some people, and the thought of getting one at the dentist’s office prevents patients from coming in altogether. The Wand offers a solution to that.

The Wand is an extremely thin needle that looks more like a pen than it does a needle. This automatically relaxes a patient that otherwise seems extremely anxious in the dental chair. A cartridge filled with local anesthetic is inserted into the Wand, and the delivery of the anesthetic is controlled by a computer (7).

The major benefits of the Wand include (7):

Single Tooth Anesthesia (his allows dentists to numb just one tooth rather than the entire lower jaw)

Three different delivery speeds (Slow, Fast, and Turbo) depending on the injection site

Reduces patient anxiety levels

Extremely thin needle that results in less pain upon injection

For those of you who are looking for other ways to manage your anxiety, we explore the benefits of taking CBD before coming to the clinic.

8. CAD/CAM

Computer-aided design and computer-aided manufacturing (CAD/CAM) is a computer software that is used to design and create prosthesis (8). A dental prosthesis is a dental appliance used to replace defects such as missing teeth or parts of intact teeth that need restoration.

Why are dentists shifting to CAD/CAM?

Faster fabrication

More precise fit

Increased predictability

Improved efficiency

How does CAD/CAM do all of this? With the help of an intra-oral scanner called CEREC, (CEramic REconstruction) that digitally transfers the information to the computer.

As previously mentioned, the source of digital light on the scanner scans the tooth in need of a restoration and all adjacent teeth that impact its function. The computer then uses this information to precisely calculate a 3D image of restoration for the tooth in question.

We use this creation of orthodontic models for several procedures, such as:

Inlays and Onlays

Crowns

Bridges

Dental implants

This all comes to life using the manufacturing part of the device, the CAM unit.

A specific material is placed in the milling unit, such as titanium, resins, glass ceramics, and zirconium oxide to name a few. The CAM unit mills the material to the precise structure created on the computer, bringing the image to life in a matter of minutes.

While it used to take several visits to the dentists for a restoration, CAD/CAM cuts that down to just one. The application of this technology are numerous and aids dentists in achieving more accurate clinical results.

Revolutionizing Dentistry through Technology

From 3-D printing to on-site milling machines, the world of dentistry has been completely revolutionized by modern technology on the dental market.

Dentists can now provide higher quality treatment faster than traditional methods. They are able to be more accurate and precise in their treatment, preventing future complications. Leading-edge equipment gives dentists more confidence and predictability, which results in improved healthcare for their patients.

It is more than a trend; It is the future of the field, and it is here now.

3D Printing + 7 More Exciting Advances in Dental Tech [in 2019]

The world is moving from analogue to digital, and so are dentists. Technology has revolutionized the dental industry to optimize patient care and satisfaction. The latest advancements have made the time you spend in the dental chair more efficient, while making sure your absolute comfort is never compromised.

Dentistry is moving forward, and I’ve listed a few ways how:

1. Dental 3D Printing

As with many other fields of science and art, the potential applications of 3D printing technology are endless.

If you ever needed a restoration procedure done, the sequence might go as follows:

Your dentist takes an impression of your upper and lower arch

S/he sends that to the lab

You both wait for the lab to create the desired dental models

You will be asked to return when the final product has been delivered to your dentist

With the advent of 3D printing, this can all be done in one appointment.

If you happen to have a tech-savvy dentist, he or she will scan your mouth with an intra-oral scanner that is then presented as a 3D image on the computer. (1) The dentist will then digitally design the desired treatment and send this information to the 3D printer that brings it to life.

A 3D printer has many uses in the dental practice:

Inlays and onlays

Dental crowns

Bridges

Implants

Mouth guards and night guards

Full or partial dentures

Orthodontic appliances (e.g. Invisalign or other clear aligners)

Not only does this save you weeks of waiting for dental labs to finish your dental product, but it also provides you with more accurate results. And, let’s be honest, who doesn’t want to skip the lengthy manufacturing process?

Whereas traditional methods allows your dentist to fix any defects after the restoration has been placed in your mouth, this newer method allows him or her to adjust any faults digitally before going to print set-up. This optimizes both your time, your dentist’s time, and your overall healthcare.

2. Digital X-Rays

Radiographs, also known as X-rays, are an essential part of treatment. They are used to diagnose many oral health issues not visible to the naked eye. This includes cavities, periodontal (gum) disease, and root infections, to name a few.

Traditionally, you dentist or dental hygienist would have film in a plastic holder and place it in the area of your mouth they would like to view. There are intra-oral and extra-oral x-rays that target different parts of the head. After capturing the images, they will be processed and analyzed by your doctor.

Although traditional x-rays have been a great diagnostic tool for many years and continue to be used for their lower cost, they have their drawbacks:

Film-based X-rays must be processed, which takes time

Processing film requires chemicals that may be toxic and hard to dispose of

Film isn’t as sensitive to the x-ray beam as digital technology, meaning there’s more radiation output from the x-ray head to produce an image

Digital radiography uses digital sensors to replace the conventional film that dentists have depended on for so many years. The sensor is connected to the computer and when it receives the image, it is immediately displayed on the screen for viewing and analysis. (2) The result? A totally digital workflow, completed in seconds.

It may be more expensive to purchase for the dentist, but the benefits outweigh the initial costs:

No use of chemicals

Environmentally friendly

Faster processing, saving valuable time for you and your dentist

Image enhancement with computer software (with high resolution originals)

50-80% less radiation than film

Images stored in electronic patient records, and sent quickly to referring dentists or insurance companies

If you are concerned about the radiation of x-rays, we have answered a few of your questions here and here.

3. CBCT (Cone Beam)

The types of X-rays we use for diagnosis vary on a case-to-case basis, and in some instances, we need a little more information than what a regular dental x-ray provides us.

Cone beam computed tomography (CBCT) is used to create 3D images of your teeth, surrounding tissues, nerves, ligaments, and bone in the maxillofacial region (head, neck, face, jaws). Think of it as 3D scanners making a digital model of everything your dentist needs to see.

Your dentist will position you in the center of the beam, and the machine will rotate around you in a 360 degree fashion. The whole process takes about 20-40 seconds for a complete scan.

Here are a few reasons a dentist may need to use a CBCT for a better look at a patient’s mouth:

Endodontic surgery (root canals): Gives clinicians valuable information on vulnerable structures such as sinuses, missed canals, and nerve channels

Implant placements: Provides accurate placement of implants in bone and the position of the inferior alveolar nerve as it relates to the placement of implants to prevent nerve damage

Orthodontic work: High quality analysis for the correction of malocclusions and facial disproportion

Diagnosing TMJ

Detecting and measuring jaw tumors

The 3-D images the CBCT produces identifies about 40 percent more lesions (3). That’s why Dr. Burhenne suggests patients get cone beam scans every 5-10 years after a root canal to identify any problems that arise.

Due to a much higher radiation exposure than regular dental x-rays, however, it is only done in cases where the information provided for treatment planning outweighs the radiation risk. That’s why the FDA recommends cone beams not be the first route for dental imagery.

4. DIAGNOdent

Dental caries, or cavities, are one of the most prominent problems in oral health care. Traditionally, dentists diagnose cavities using bite-wing x-rays and a dental explorer. Most cavities occur on the pits and fissures of the tooth, but many go undetected by using traditional methods.

One study showed sensitivity (ability of a test to correctly identify those with a disease) and specificity (ability of a test to correctly identify those without the disease) values of 62% and 84% with the conventional method.

In other words, dentists correctly detected cavities 62% of the time, and correctly determined no cavities 84% of the time (4).

Our goal as dentists is to not only treat cavities accurately, but also to arrest and prevent them in their pre-cavitation stages before a potentially rapid spread of decay. With the introduction of instruments such as the DIAGNOdent pen, in conjunction with our traditional methods, we can do just that.

The laser fluorescence it emits allows us to detect cavitated lesions from non-cavitated lesions.

At the 655 wavelength the device operates, cavitated lesions result in higher scale readings, while non-cavitated lesions result in lower scale readings (4).

DIAGNOdent helps improve treatment in several ways:

Audio signal allows dentist to distinguish between different scale readings

Increases detection accuracy at earlier stages than traditional methods alone

More precise in identifying pit-and-fissure cavities and proximal cavities

Minimally invasive

Read more about how dentists are diagnosing cavities with lasers in another post.

5. Intra-Oral Scanner & Intra-Oral Camera

If you have ever needed restorative or aesthetic work done, you know that one of the first things your dentist or dental assistant does is take an impression.

You see them mixing several materials together to create a uniform consistency, transfer that to a tray, and insert it in your upper or lower arch. They hold the impression material down for a few minutes until it sets, and then remove it.

Most patients are very uncomfortable with this process due to the taste of the material, time it takes to set, and uncontrollable gag reflexes. Patient comfort, along with several other factors can affect the accuracy of a traditional impression due to:

Proper material preparation

Mixing material

Application technique

Setting time

These challenges can lead to improper margins and missed details, resulting in improper fitting of restorations as well as improper occlusion (bite). Digital dental impressions provide an alternative to these complications so that a patient’s teeth may be restored without as much discomfort.

Intraoral scanners are shaped like a pen and project a light source onto the area to be scanned, such as your upper and lower arches for instance (5). Your entire mouth anatomy is captured by imaging sensors and projected onto a computer.

This creates a 3D model of your teeth and surrounding tissues and allows your dentist to diagnose and treat you with increase accuracy and precision.

Some reasons why dentists are moving from traditional to digital impressions are:

Increased patient comfort (this is especially true for those who struggle with mouth breathing, as the airway isn’t blocked by a big tray of impression putty)

No gag reflex or pain

Time efficient

Improved quality and detail of impressions for better-fitting restorations

Reduction in technique sensitive errors

Eco-friendly solution that reduces the need for plastic and impression material

Increases communication and understanding between dentists and patients

The latest technology includes intra-oral cameras that allow your dentist to capture images from points during the scan to be enlarged. This provides a greater overall comfort for the patient, better diagnosis, and more efficient treatment planning.

6. TekScan

Your oral cavity is a complex system made up of muscles, bones, and ligaments. These must all be in harmony for you to talk, bite, and chew properly.

If one of these components is out of balance, it can lead to several problems such as:

Temporomandibular joint (TMJ) disorder

Headaches

Bruxism

Fractured teeth

Broken restorations

Tooth pain  

Gum disease

Traditionally, dentists check occlusion (the contact between teeth), with articulating paper. You will notice that your dentist will put this colored piece of paper between your teeth and ask you to bite down a few times. Your dentist will then diagnose these colored marks left on opposing teeth to check that they are contacting properly.

Articulating paper is also used to check if new restorations, such as fillings, inlays and onlays, crowns, and bridges are in proper occlusion with the rest of your dentition.

(6)

We feel this! A layer in our system is entirely made for symptom holders and seperating symptoms. Our psychiatrist and therapist acknowledged that and we work with it, for anyone who might be curious if their therapist can believe in it. There are some that absolutely do. She even reminds us sometimes that it's normal for X to not understand Z because their symptoms are so different.

Disorder Differences in Systemmates

Systemmates share the same brain, which often leads to the assumption that they're all affected the same by the brain itself. Its wiring, its abilities, and its disabilities. But symptom holders or those with intra-disorders are fairly common--at least in circles we run in--and they're not often talked about for fear of fakeclaiming or appearing ableist. We have headmates who are affected in all sorts of different ways by our disabilities. Some find things harder than others, while others actually find some tasks or symptoms easier to manage. It absolutely varies from headmate to headmate, which makes certain headmates better suited for fronting during certain times than others.

Merlin is more affected by our psychosis, particularly hallucinations, and xe tends to be more susceptible to paranoia. Mystery is a psychosis holder too, and has more positive symptoms like hallucinations than the rest of us, but is less affected negatively by it. It often hallucinates and falls into delusional thinking, but it's not really too bothered by it. So Mystery is a good choice for someone to front when we're having a psychotic episode. Sometimes, having Merlin cofront with Mystery makes it easier for Merlin to not be so susceptible to xyr symptoms.

I (Martin) have more obvious anxiety than the rest of us, and struggle much more in social situations. I'm much better at hyperfocusing on tasks, though. So I'm better suited for staying home and working on whatever the current project we have at the time, or keeping our to-do lists in check. Vince on the other hand is calm in most social situations that are more professional--so he's good for business meetings and such. In more casual conversation though, Vena and Merlin are much better at it and better suited to non-professional social groups.

Vince is an intra-NPD holder and also holds stronger symptoms of our BPD. He struggles immensely with percieved rejection, much more than the rest of us. But he also almost completely lacks empathy, which makes it much easier for him to be calm and logical in stressful situations. He finds it easier to help friends and those he cares about during stressful times because he's not weighed down by feeling their emotions--whereas the rest of us might break down from stress.

We talk a bit about mental disability differences in headmates more than those who differ physically. Somehow it seems more controvertial to mention that we have headmates that differ with physical symptoms while even in safe system spaces. It seems like most people (us somewhat included) mainly think of symptom holders as a mental disorder thing--a line of thinking we're trying to dispel. Headmates can have different disabilities and symptoms of all kinds, and it's not ableist or "harmful" to know that and speak about it. Headmates with different conditions to the body need to be recognised more.

Mike needed a cane in his memories and he absolutely needs our cane when he fronts more than the rest of us. He feels more at home and like himself having a cane by his side here, though, so it's good we already had one. I (Martin) need it more too--my joints are just more prone to pain. But our cane folds up nicely into our bag, so if we switch out in public, it's always with us just in case. Even if it's silly, we feel safer having a cane too--I mean, it's a metal pole. We're out as trans and clearly not your Regular Society Member, so it provides some feeling of safety to have.

Jayfeather was blind before, and since coming here he sure can see now, but he's much more light sensitive than the rest of us. The feeling of being able to see was nice at first, even if it was foreign, but sometimes he feels it's not worth the hassle. He needs to wear sunglasses when fronting because his eyes just end up hurting from even small amounts of light. Crowley is the same, except he wasn't blind in his memories--he just got used to always wearing sunglasses in his life to hide how his eyes looked, and needs them here now. They're both more prone to migraines due to this.

Merlin is more shaky on his feet than others who front often. His legs are digitigrade and in headspace he has his wings and tail to balance him there--but in the body, he doesn't have any of that. His legs are the wrong shape and he has no counterweight to his posture. Even with our cane, he's more prone to tripping than most.

Mystery was a godlike being that didn't need to eat human food, or any physical food at all. It often forgets that eating, sleeping and going to the bathroom are things the body needs to do, because it doesn't often feel the need to do them. That can be good if we're running low on food, or if we can't eat for a while such as before a medical procedure though, so it's useful in its own way. Mystery is also not used to using its hands for intricate things like tying shoelaces, as it's hands before we're longer, bigger, and mainly nonphysical. It didn't need to be intricate, so it's hard for it to do things others in here can.

There's so many more examples in our system. The thing is, there can be positives and negatives to any disorder, really--and headmates are no different with that. We don't necessarily assign headmates "roles" or "jobs" based on their symptoms or lack thereof, but for us to function better as a collective, people tend to gravitate toward doing certain things they know others can't. It's important for us to know how we differ with our disabilities, and work around them together as best we can.

Systemmates with different symptoms aren't uncommon, and they're not mocking disabled people, or lying for some benefit. I'd argue that for some systems with symptom holders or intra-disorder holders, it's increcibly important to know about how you differ and how to work together to be functional--whatever functional means for you.

[interstellarsystem]

Intra-Disordered

We don't do coining posts often, if at all, but this one applies to some of us and we figured we'd tentatively share.

Intra-Disordered: A person within a system with the experiences of having a disorder/symptom the body does not have or is not known to have.

Intra as in "within", referring to within a headmate.

This can be the result of trauma, isolated symptoms caused by trauma-holding, symptoms a headmate has in source, psychosis, or other reasons. This can also include symptoms of a disorder the body has that are not experienced by others in the system, such as a system with autism collectively being okay with sounds of all types, but one of them is sound-sensitive.

To be used with sublabels if you prefer, such as intra-ADHD or intra-anxiety, and can also refer to specific symptoms, such as intra-hallucinations or intra-tics. If you'd like a headmate role-esque phrasing, intra-disorder holder is an alternative, which can be coupled with the sublabels such as intra-BPD holder.

This term is specifically to differentiate from bodily-disordered experiences while also having ways of easily phrasing disordered symptoms the body as a whole does not have, while keeping both validated. Similar in purpose to "exotrauma"--to acknowledge both experiences while they are similar, but separate, and both are deserving of support.
