Lower Anatomical Orthosis

The Anatomical Removable Orthosis
The lower anatomical orthosis I advocate is a specialized dental appliance that is orthopedically designed to match the physiologic function of the patient’s jaw and head posture. (Read more….). It is scientifically determined using computerized jaw tracking technology, low frequency TENS and EMG data technology is used to determine and confirm the bite registration which is key to establishing an “Optimized” jaw relationship. Patient’s who experience, jaw pain, headaches, neck aches, facial pain and or has an over-closed bite can benefit from this therapy.

This anatomical appliances main objective is to orthopedically relign the mandible to the cranium to bring support, balance and allow true physiologic rest to the musculature.

Dentist Responsibilities to Making the Orthosis Treatment Effective
In today’s arena of TMJ treatment arena there are many types of splints and appliances (upper splints, lower splints, anterior deprogramers, flat plane splints, MORA’s, discluders, soft splints, lower splints, pivot appliances, etc.) that dentist have attempted to use for their paining patients as a means to try to help remedy the various muscular and jaw joints symptoms. Many of these appliances have produced varying results – some effective, others ineffective.

It has become common knowledge among patients that not all splints including orthotics work.  Why is this?

Dentist often assume that opening one’s bite to some vertical dimension is supposedly suppose to help the patient. Although, this may seemingly be a good thing in an attempt separate the teeth from  coming together and also allowing the musculature and TM Joints to relax at a better relationship the vertical dimension of these appliances is opened by some educated guess often by the dentist and never really “physiologically” relaxed and measured objectively with low frequency TENS and or determined with physiologic measuring technology.

It is the dentists responsibility to identify the correct mandibular  to maxillary jaw relationship (the vertical, antero-posterior, frontal/lateral, pitch, yaw and roll).    If a correct jaw relationship is physiologically determined (not just established to a habitual accommodated jaw position) and also properly adjusted, why would any dentist need to use multiple appliances (day time wear, night time wear) to resolve TMD/craniofacial pain?  Nature didn’t give us day time set of teeth to wear and for night, a night time wearing set of teeth.  One good and properly adjusted orthotic appliance should suffice to meet both the gnathologic as well as neuromuscular requiements to reduce the spastic muscle tension.

It is the dentist responsibility to make sure the orthosis or any appliance that is being implemented is properly adjusted so that the orthosis feels comfortable and does not feeling like an irritating foreign object in the mouth.  It’s the design of the orthotic and how the occlusal biting surfaces are adjusted that makes the difference.

The  patient should know within 24 hours whether the orthosis/appliances is properly adjusted or not, whether it feels comfortable or not.  The patient should not feel like they have feeling like they have to tolerate an appliance that does not feel right when the bite their teeth together.  The orthosis should be properly adjusted so the patient can chew and eat food with the orthosis.  It should not cause teeth to be sensitive, if it does, ask your dentist to check the bite and make the proper adjustments.  The orthosis should not cause more TMJ and muscular pain.  If it does ask your dentist to identify, mark and adjust the occlusal premature interferences that are triggering the imbalanced muscle responses.

One good thing about a removable orthosis – If it doesnt’ feel right you can always take it out and let your dentist know that something is wrong.  Be patient with your dentist so they can troubleshoot the biting occluding problem so you can get the resolution you are seeking.

Four Types of Neuromuscular Dysfunctional TMJ Challenges

by Clayton A.  Chan, D.D.S., M.I.C.C.M.O

Four main categories or types of  neuromuscular dysfunction problems within the  TMJ pain arena. It is these 4 types of cases that have challenged a majority of neuromuscular minded clinicians. Each of these types requires specific occlusal protocols to be understood and followed when implementing orthotic therapy.  It is clear from numerous TMJ pain patients complaints that TMJ treating dentist across the board have often failed in this area because of their lack of understanding the dynamics of the proprioceptive occlusal responses feedback mechanism to the masticatory and CNS system.  Specific design requirements as well as micro occlusal management skills and protocols must be followed if a lower orthotic is to re-establish physiologic health and optimal function in a timely manner.   Myofacial pain related to TMD should not be a hit an miss phenomenon, but will continue as long as the dentist do not discipline themselves in the art and science of neuromuscular occlusion.

Today’s TMJ treating clinician often overlook and fails to recognized that each of these 4 conditions require specific occlusal management protocols to be followed and implemented if effective and positive outcomes are to be expected. Not all TMJ, TMD (temporomandibular joint dysfunction, MPD (myofacial pain dysfunction) or CMD (craniomandibular dysfunction), although in this clinicians perspective, should be treated in the same manner (cooking cutter protocols) although the lower anatomical orthotic has been found to be very effective and useful when implemented properly.

1) Cervical Dysfunction TMJ Disorders
2) TMJ Primary Disorders
3) Class II, Division 2 TMJ Disorders
4) Anterior Open Bite TMJ Disorders

The significance to optimal treatment planning is based on sound stabilization techniques and occlusal management of the mandibular orthosis. A thorough understanding of each type of dysfunction requires a specific feature that meets the requirement of physiologic function. Knowing these features will assist the clinician to better comprehend how best to manage and transition the case to a finalization stage of treatment.

Symptoms That Accompany These Problems

  • Unresolving neck and shoulder aches in the upper trapezius region
  • Unresolved occipital pain
  • Unresolving temporal pain (unilaterally or bilaterally)
  • Unresolving facial masseter pain and tenderness (unilaterally or bilaterally)
  • Pain behind the eyes (retro, sub and supra orbital)
  • Unresolved pain at the  lower posterior border of the mandible (unilaterally or bilaterally)
  • Unresolved pain in the SCM and Scalene muscles
  • Unresolved pain in the digastric/suprahyoid muscles

These are the common unresolved sights of pain due to “Mandibular Torque”  that will persist as long as mandible to cranial relationship is strained.  Imbalanced bite/occluding forces are present even if the centric bite appears to be even and balanced.  Functional movements are often overlooked and not understood by most TMJ experts, because of their lack of occlusal-muscular awareness as to how the physiology works.  Many have attempted to use adjunctive therapies to band-aid these unrelenting pain problems when the clinician does not understand the occlusal issues at play, yet some within the TMJ bio-psychosocial community continue to perpetuate their philosophy to the masses and do not believe that occlusion relates to TMD.  Even many within the NM dental community still have not been adequately trained to recognize these issues even at a basic level and will continue to pass these problems off as untreatable and part of the so called “TMJ syndrome”.  Discipline on the part of the treating clinician is required.

Note: This author, treating clinician, teacher and researcher differs to believe what TMJ traditionalist have been advocating for years.  90% of TMJ is related to muscles and abnormal occlusal function.  Leaving the patient helpless and paralyzed by promoting a pharmocologic psychosocial philosophy of  TMJ is a dis-service to the TMJ paining community and negates the 45 years of science and technological advances that has brought a great understanding of what TMJ/TMD is really about.

To properly treatment plan these problems requires the clinician to understand what to look for during the clinical examination process as well as to recognize the hidden indicators of postural, mandibular and joint dysfunction. How to objectively evaluate the patient’s complaint by implement proper bite registration protocols using low frequency TENS and computerized mandibular scanning technology will better assist the dentist in identify the excessive vertical dimensions as well as the proper neuromuscular trajectory required to stabilize the TM joint and muscular systems. Implementing this knowledge and occlusal management techniques will lay the foundation toward sound comprehensive treatment planning.
