Repeated Injections of Botox into the Masseter Muscle... A Longitudinal Study

The authors of this study examined mandibular bone before and after subjects received Botox injections into each masseter muscle. These volunteers were healthy adults (22-48 years old), both male and female, who wanted injections to slim their faces.

Washington Post Article on TMD

The Washington Post recently featured an article on Temporomandibular Disorders. Below is an excerpt from that article and a link to the full story.

Partnering to Improve Chronic Pain Care

The National Institutes of Health (NIH) held three meetings this summer with the goal of developing the first public-private partnership (PPP) to develop safe and effective treatments for chronic pain, as well as new treatments for opioid addiction and overdose.

TMJ Patient RoundTable Project: Status Update

The TMJ Association is acting as the catalyst to develop the TMJ Patient RoundTable, a broad initiative to advance the interests of patients with temporomandibular disorders (TMD). It encompasses collaborations with all stakeholders and

The Latest Treatment Craze in TMJ…Neuromuscular Dentistry

  • Nov 27, 2015

Neuromuscular dentistry is a dental treatment philosophy intended to correct a “malalignment”of the jaw at the temporomandibular joint and produce a balanced bite. The neuromuscular dentist uses several computerized instruments to measure your jaw movements and jaw muscle activity to determine the extent of your problem and to establish a “physiologic rest position” for the jaw. Here are some of the measurement techniques and procedures used:

  • Sonography – measures vibrations from the joint when you open and close your mouth to identify joint derangements.
  • Electromyography (EMG) – involves placing surface electrodes over the jaw muscles that pick up electrical impulses and send them to the recording instrument. It is used to measure the activity in the muscles during various movements.
  • Jaw Tracking (Electrognathograph, Kinesiography) – analyzes mandibular movements three dimensionally. A headset is placed on the patient and a magnet is attached to the lower front teeth. Recording of the lower jaw movement is then made.
  • TENS – ultra-low frequency electrical stimulation of the muscles to relieve muscle spasms and pain and help establish a “physiologic” jaw position.

Once the rest position of the jaw is determined, the patient undergoes extensive restorative dental procedures or orthodontics to maintain this new position.

Neuromuscular dentistry can cost from $3,500 to $25,000+ for 4-6 months to one year or more of treatment.  Insurance companies typically do not cover the TMJ- related costs due to the lack of  a scientific evidence base for such treatment.

According to the American Association For Dental Research’s March 3, 2010 Policy Statement on Temporomandibular Disorders (TMD)  “…the consensus of recent scientific literature about currently available technological diagnostic devices for TMDs is that except for various imaging modalities, none of them shows the sensitivity and specificity required to separate normal subjects from TMD patients or to distinguish among TMD subgroups.”  In other words, those who practice neuromuscular dentistry have their own standards for what are normal and abnormal readings which may lead to a “false positive” - meaning people may be told they have a TMJ problem when they really don’t, leading to unnecessary treatments.

Neuromuscular dentistry is NOT a specialty recognized by the American Dental Association.  Although a variety of healthcare providers advertise themselves as TMJ specialists, treatments available today are based largely on beliefs, not on scientific evidence.
