William Rea MD

When I lived in the Dallas area I had the privilege of seeing William Rea MD, FACS, FAAEM. He has diagnosed and treated many patients with TMJ implants, as well as, published in the Medical Journals about his treatment. The first implants were done in Texas so there was a large concentration of patients in the area. Of course, he has had patients come from around the states and the world for his diagnoses and treatments. I made an appointment after reading the research article written by him and Deborah N. Baird. After various tests he diagnosed me with "Toxic encephalopathy, immune deregulation, autonomic nervous system dysfunction, and multiple chemical sensitivities."

"Fourteen patients with temporomandibular joint (TMJ) alloplastic implants who exhibit chronic signs and symptoms of chemical sensitivity are discussed. These patients were well before their implantation. Memory loss, confusion, imbalance, dizziness, non-immune vasculitis, petechiae, spontaneous bruising, edema, Raynaud's phenomenon, pain and autoimmune dysfunction are some of the symptoms and signs seen. Laboratory data show immunological abnormalities, including positive autoantibodies and altered T and B lymphocyte function. Provocation skin testing shows reaction to their implant material. The symptoms of patients with jaw implants are similar to those patients who experience complications from their breast implants. Similar abnormalities are seen with SPECT brain scan, in the autonomic nervous system, as well as laboratory data. All patients were sensitive to a wide variety of substances including toxic and in some cases to non-toxic chemicals (foods, pollens and molds). These same parameters were also similar in the patient with a known toxic chemical exposure without implants. A comparative discussion of the different parameters in all three types of patient is presented. A successful therapeutic intervention was developed using a massive pollutant avoidance program, nutritional supplementation and injection therapy for biological inhalants, foods and some chemicals. When indicated, intravenous therapy with antioxidants and heat depuration was added to their treatment regimen." Baird, D.N., &Rea, W.J. (1999). The Temporomandibular Joint Implant Controversy. Part II: Its Clinical Implications. Journal of Nutritional and Environmental Medicine, Volume 9 (no.3), pp. 209-222.

I would like to note that the breast implants were never recalled by the FDA. The Vitek implant was recalled by the FDA because of "catastrophic devastation." The FDA Enforcement Report has stated "Debris in the joint from the implants can contribute to progressive bone degeneration of the condyle of the mandible and/or glenoid fossa and to foreign body responses which could start at this area and be carried throughout the immune system." http://www.fda.gov/bbs/topics/ENFORCE/ENF00033.html [This page has been removed from the FDA website]

" I had a Teflon implant removed from my TMJ joints in 1987 which had been implanted in 1984. At the time there seemed to be no negative reaction although the surgical report stated foreign body reaction had been observed. Unfortunately I was involved in a car accident complications from which affected the TMJ requiring grafting of rib material to reconstruct the jaw.

My question is: Are there any tests to see if the teflon residue can be detected in either the tissue removed in the later surgery or even now post surgically (there seem to be some complications in the right joint)."

A TMJ implant, which was made out of a Teflon-Proplast material and used as a meniscus replacement. With hindsight severe degenerative changes occurred in about 90% of cases.
The implant disintegrated under load, producing a foreign body giant cell reaction , subsequent bone erosion and lymphadenopathy.

Vitek withdrew the implant and went into liquidation. The U.S. Food and Drug administration subsequently produced a consensus statement advising the removal of all symptomatic implants and 6 monthly radiographic follow up of asymptomatic patients. Once the source of the inflammatory response is removed then the migration of this tissue to the lymph nodes ceases.

A foreign body reaction is seen after any implantation of any alloplastic material and is a chronic inflammatory response. However if the response is low grade and produces no symptoms then no action is necessary. There are analogies here with the similar response to reactions to implantible silicone breast implants.

Unfortunately the search for a biocompatible TMJ implant has not produced any serious contenders and in the UK most TMJ reconstructions are performed with autografts of cartilage capped rib (costochondral grafts) or new menisci are formed by using interpositional muscle or dermal grafts. The main prosthetic TMJ under consideration in the UK is the Christensen prosthesis composed of a cobalt-chrome articular fossa and a methyl methacrylate condyle replacement attached to a cobalt chrome ascending ramus. However there appear to be no long term solutions to the multiply operated patient and only about 5% of all patients treated for TMJ disorders undergo open TMJ surgery.
