Questions related to Temporomandibular Disorders
In natural dentition, periodontal ligament and proprioceptive sensors act as shock absorbers and provide critical feedback for force control. In complete dentures, soft liners or gum tissues partially fulfill this role. However, in full-mouth implant rehabilitation, such mechanisms are absent.
This raises the question:
- Do TMJ, muscles, and ligaments take over as shock absorbers in these patients?
- If so, does this lead to increased risk of temporomandibular joint (TMJ) disorders over time?
Interestingly, evidence remains sparse. While theoretical concerns suggest higher TMJ stress, longitudinal studies specifically evaluating TMJ disorders in full-mouth implant patients across different time intervals are lacking.
Open for Discussion:
- What are your clinical observations or research findings regarding TMJ health in these patients?
- Can implant design or occlusal schemes mitigate potential TMJ stress?
Let’s explore this together!
Stabilization splint is a common non-invasive treatment options used by dentists for temporomandibular disorders such as myofacial disorders, or disc displacement without reduction.
These splints typically vary in thickness between 2-3 mm. The appliance have a potential to reduce muscles tone and increase the amount of vertical opening.
Despite these dramatic effects, the effects of stabilization splints on respiratory parameters during sleep have hardly been studied.
Hello everyone! I am currently doing an analysis of the occlusal analysis. Now I have a pressure sensor for the mouth, just like Tek-scan. I am trying to link stress analysis with a certain oral disease (such as Temporomandibular joint disorder syndrome-TMD, periodontitis) and establish a series of graded diagnostic criteria or rate the reliability of implants based on occlusal analysis. Sorry I don’t know a lot about stomatology.Is there any research on the relationship between occlusal analysis and oral disease diagnosis, rather than just outputting bite force data?Thanks!
I am interested in your opinions on the term temporomandibular disorders.
Recently I started to realize that the use/overuse of this term brings more problems than benefits. There are few things that are problematic for me in this matter.
First of all, what does the term TMD actually mean?
Of course, there are definitions that state that TMD is a group of clinical problems or a group of musculoskeletal and neuromuscular disorders affecting TMJs and muscles of mastication.
However, the available definitions are very general and make the term TMD endless list of all possible disorders that can affect the TMJ or muscles of mastication. What is the actual benefit of creating such group of disorders?
Wouldn’t it be easier to just relate to those problems as disorders of the temporomandibular joint and disorders of the masticatory muscles? Especially that it is now well known that those disorders have completely different etiology and create different clinical problems (pain, clicking, limited mouth opening).
The definition of TMD – teaching and communication.
The fact of having the definition that covers such broad spectrum of disorders creates a problem with communication. Statements and generalizations about TMD are very difficult and sometimes impossible due to heterogeneous character of the group.
We can find many examples of this problem in titles of research papeper. „... is related to TMD”, „... is / is not effective in TMD treatment” etc. Every time I read something like that I have to guess what the autor/s actually mean writing TMD, to which disorders/problem they are referring to? I also noticed that the term TMD means different things to different people. For instance, for a maxillofacial surgeon the term TMD is related to different clinical problems (osteoarthtis, congenital TMJ abnormalities etc.) than for orofacial pain specialist (e.g. myofascial pain). This creates great confusion in communicating with each other while using term TMD.
In my opinion it is also a barrier in teaching TMD. It would be much easier to teach about disorders of the TMJ and/or disorders of masticatory muscles than poorly defined group of disorders that often have nothing to do with each other (eg. TMJ synovial chondromatosis and myofacsial pain – both TMDs).
Most (but not all) of the researchers and clinicians refer to TMDs as to chronic orofacial pain conditions. But do current definitions are fully compatible with this approach?
Shouldn’t we redefine the therm TMD or just start using specific diagnoses when publishing or just communicating with each other instead of constantly using very unspecific term TMD?
Disclusion Time Reduction (DTR) is one of the treatment used for TMD pain. As far as I understood, the main concept here is to use technology to scan the occlusion with a T-Scan (digital scan) to analyze occlusion contacts. Also use electromyogram EMG to analyze muscle activities. These finding help the operator to make an occlusal adjustment procedure called immediate complete anterior guidance development (ICAGD). This occlusal adjustment will reduce the time for the teeth to disclude which will be reducing the muscle activity and the reduction of TMD pain.
Now, all of this sound good on papers but the problem with this method is
- The high cost of the procedure
- There are only few articles about it mainly written by Dr Robert B. Kerstein
My question is: Has anyone used this method? Or had training or research?
Temporomandibular Disorders and body posture
Some article shows that tooth contacting habit have a correlation with TMD. Most of them using a questionnaire to investigate the evidence. I would like to know, Is there any information about the duration of tooth contacting habit? The duration might be shorter than clenching/tonic.
Increase in diet hardness? Atrophy of the contralateral masseter muscle by botox injection?
I would appreciate any advice you may have.
I am writing a book about the intelligent design of the teeth, including the biofunctional mechanical forces of occlusion, and the method of construction of dental restorations, by copying the trilaminar pattern of the teeth. Any information about my question will be appreciated.
