A Re-evaluation of the Meaning of NMD
"GNEUROMUSCULAR" DENTISTRY - What It Is and What It's Not
by Clayton A. Chan, DDS, MICCMO
by Clayton A. Chan, DDS, MICCMO
I am posting this to clear up confusion as to what Neuromuscular Dentistry and NM Occlusion is about. Because there are some who profess to be "Neuromuscularly" trained, but in reality have very little understanding and appreciation for the Gnathologic occlusal concepts which are the foundation to neuromuscular dentistry. NMD is not only about scans, EMGS and jaw tracking data, it is about occlusion and it’s relationship to the trigeminal system as it relates to postural system. Let’s not forget that it relates to CLINICAL applications of TMD, restorative/prosthetics and orthodontics. It’s not an academic exercise of knowledge, but rather it should be a display of how the teeth, muscles and joints are functioning (HEALTH not dysfunction) in relationship to the bio-physiology, neurology and their impact to the masticatory system.
The concept of NMD is not new, neither should it relate to marketing exploits in the name of post graduate dental education. It is a "discipline" in dentistry that requires attention to detail to the core principles that every dental student has learned in their dental training. It is certainly not about an overuse of technological advancements for the learning student to convey to their patients that what they understand about EMGs, jaw tracking and orthotics is to over ride the actual patient responses of ill feeling bites, imbalance of musculature as it relates to restorative reconstruction. LEARNING THE BASICS IN OCCLUSION IS KEY! The proper application of the GNM principles as taught at OC is key!
When doctors who begin to use these advanced techniques in manners and cannot properly interpret the EMG and jaw tracking data correctly or apply the micro occlusal management principles from a complete clinical perspective, even though in their mind that the data may appear to be normal or correct as per their understanding, it behooves all to assess their training and understanding of scan interpretation, especially when restoring patients through the various phase of reconstruction or restorations (phase I removables, phase I fixed orthotic, phase I porcelain orthotics and or phase II restorative). If the scans appear to be normally low EMGs and the trajectory looks like it is right on trajectory sagittally and frontally and the patient is complaining that they don’t have a bite, then perhaps a reassessment as to one’s understanding of scan interpretation is in order (Level 5 Advanced NM Bite Refinement/K7 Training and Interpretation). If the EMG and jaw tracking data as per one's understanding shows a balanced occlusion, yet the central nervous system is not calm or neutralized then one's understanding of GNM (gneuromuscular) and or NM (neuromuscular) needs to be reassessed.
If the patient is having a difficulty with the dentistry provided even if it was performed in the name of GNM or NM and one is not sure what to do….don’t tell the patient that all the scans appear normal and that there is nothing wrong with the dentistry. They are not whiners and complainers for no reason. They have a legitimate concern that needs further investigation, occlusal understanding and another level of skill sets may be required. It is wrong to tell the patient that there is nothing wrong when the Scans appear to be OK to cash this patient to the waste heap of “NM” failures. Let’s reconsider what we have been taught. (Of course the TMD patient must also realize there are no guarantees, when TMD involves multiple layered factors that involved not just structural/anatomical postural issues, but even more the emotional/psychological stressors as well as biochemical issues that often patients rarely want to acknowledge with their dentist). Learn from those who really practice what they preach. Use your knowledge, skills and good judgment to help your patients and find a resolution to the problem. Be patient, compassionate, respectful of others work and listen to your patients carefully…sometimes they know more than the treating doctors…why because some of them are experienced and have read, learned educated themselves amongst the numerous practitioners they have visited, have been the recipients of many doctors treatments and therapies, yet continue to seek for real answers to real problems.
As long as Neuromuscular clinicians continue to pretend to hide under the covering of their scans (not really understand OCCLUSION management principles and the importance that microns matter) not fully comprehending the GNM principles what they mean as they relate to CLINICAL TMD pain treatment, restorative occlusal therapy problems and orthodontic/orthopedic issues, then scan interpretation is only a lopsided perspective of what NMD and GNM really advocates.
Orthopedic Dentistry, Orthopedic Occlusion, GNEUROMUSCULAR Occlusion or Gneuromuscular Dentistry is perhaps an updated means to convey the full package of what NMD originally intended. It shouldn’t convey something less than a complete understanding of both neuromuscular and gnathologics…it is really plain dentistry that requires self discipline.

Use of the Orthotic
by Clayton A. Chan, D.D.S., M.I.C.C.M.O.
There are several different aspects to consider regarding the use of orthotics.
1) Medico-legal – standard of care is that occlusal therapy be reversible as per ADA statement, removable orthotic appears to fit this criteria better. Especially, to the non NM clinician. It looks more mainstream to the traditional clinician. Much less likely to damage the patient’s own structures when the appliance is removed, whether the patient takes it off or we dentists take it off. Which would make you feel more comfortable if your TMD pain patient ever decided to leave your practice for whatever reason…Leaving your practice with a fixed orthotic in the mouth or with a removable?
2) DOT Occlusal Management – Significantly easier to adjust the bite outside the mouth than in the mouth, especially with paining TMD patients that are not yet committed to phase II treatment.
3) When patient not yet committed to phase II level therapy, removable is less likely to cause a more permanent joint change, because of the capability to remove the appliance when the patient wants to. With fixed the patient has no control of the situation and you own the bite (patient now controls you)! If patient is having difficulties with their bite using fixed on a weekend you have to go in and help, if removable they can take it, see them on Monday. Harder to divorce from a patient who has been in fixed vs. a patient in removable.
4) Removable is safer for the doctor in patient management: The patient can always pull it out of the mouth if the bite is bothering them, with the fixed orthotic the patient can’t do that and will require doctor help and assistance. Haven’t we all had a patient who told us that they could not tolerate their new bite?
5) After 30 day fixed orthotic trial period and patient is not ready to proceed forward with finalizing treatment, what do you do then?
6) Paining TMD patient is not always prepared to move forward with a phase II finalizing mode of treatment after 3 months of orthotic therapy. Most of my TMD pain cases are not ready for phase II for at least 1 year, I don’t want the liability for hygiene issues or any other things that would happen underneath the fixed orthotic.
7) Bite Management is much easier and simpler when setting up the case to transition into Phase II. (Any mandibular shift/change that occurs during the course of treatment is easily transferred without the worries of having to cut off the fixed orthosis to get a lower arch wax up. You don’t have the worries to cut off orthotic, maintain and record the bite for the lab, and then place another fixed orthotic which must be exactly and identical to the same orthotic position you just cut off.
8) Removable orthotic is less hard work vs. fixed orthotic with TMD pain patient. Do you like to adjust bite in a laying down position intra orally or a sitting up position extra orally? Is coronoplasty/ micro occlusion easier intra orally or extra orally?
9) When you need to resurface the orthosis. Which is easier fixed intra orally or removable extra orally?
10) After resurfacing how much energy is required to coronoplasty intra orally or extra orally? Think of the emotional stresses on yourself when dealing with a high proprioceptive paining TMD patient?
Ask yourself several questions:
Why do many prefer the removable orthotic rather than a fixed orthotic?
Is it really easier to manage the TMD paining case with a removable or fixed orthotic?
Why does the dental profession (as a Standard of Care) recommend conservative and reversible therapy especially amongst TMD/occlusal philosophies?
