New Report on Temporomandibular Disorders: Priorities for Research and Care

Over a year and half ago, the National Academy of Medicine (NAM) began the most comprehensive study ever undertaken on Temporomandibular Disorders (TMD). The study assessed the current state of TMD research, education and training, the safety and efficacy of clinical treatments, and associated burden and costs.

Statement by NIDCR Acting Director on the National Academies of Sciences, Engineering, and Medicine Report on Temporomandibular Joint Disorders

I am pleased to announce the release of the National Academies of Sciences, Engineering, and Medicine (NASEM) report, Temporomandibular Disorders: Priorities for Research and Care. As underscored by the comprehensive report, temporomandibular joint disorders (TMJDs) are a diverse and still poorly understood set of complex, painful conditions affecting the jaw muscles and tissues, temporomandibular joints, and associated nerves. Clearly, there is much more to be understood, and these conditions continue to confound medical and dental health care providers and researchers.

Have you seen the film Dark Waters?

The Film. Dark Waters is about attorney Robert Billott's real-life 20 year legal battle against DuPont chemical for releasing toxic waste - perfluorooctanoic acid, or PFOA - into Parkersburg, West Virginia's water supply, with devastating health effects on the townspeople and livestock. PFOA, also known as C8, is a man-made chemical. It is used in the process of making Teflon and similar chemicals known as fluorotelomers.

Drug Induced Bruxism

The authors of this article state that orofacial movement disorders (bruxism) are treated typically by dental professionals and not by those specialists (neurologists) researching and treating the other movement disorders (Parkinson's disease, Huntington's disease, tremors, etc.). Again, this is more evidence of the complexity of TMD and the need for multidisciplinary research and treatment in TMD.

FDA Issues Warning Letter to Nexus CMF for TMJ Implant Devices

  • Sep 5, 2019

On June 30, 2015, the Food and Drug Administration’s Center of Devices & Radiological Health sent a warning letter to the President of Nexus CMF telling him that, “Nexus CMF has committed a prohibited act under section 301(q)(1)(c) of the Act by failing to comply with requirements under section 522 of the Act, and your P000023and P00035 devices are currently misbranded under section 502(t)(3) of the Act. It is also a prohibited act under section 301(a) of the Act to introduce or deliver for introduction a misbranded device into interstate commerce.”  

The TMJ Association recently learned of this warning letter and verified with the FDA on November 11, 2015 that this letter is still in effect.  Click here to view the warning letter.

Nexus CMF is formerly TMJ Medical, formerly TMJ Implants, Inc., and commonly referred to as the Christensen device. 

What this means for patients…

Nexus CMF is currently prohibited from selling their TMJ total and partial joints to patients, surgeons and hospitals. If you or someone you know has received this implant after June 30, 2015 or is anticipating getting one in the near future, you should report this to the FDA’s MedWatch system. Please feel free to contact the TMJ Association at info@tmj.org if you need any assistance with completing a report or would like to file it anonymously.

We’d like to remind patients that any time you experience problems or adverse events related to TMJ devices, including splints and jaw implants, it’s important to notify the FDA of these issues through the MedWatch system. You can view TMJ implant complaints and problems filed by others through the MedWatch system at the FDA's Maude Report website.
