DOUGLAS H. MORGAN, DDS

Dr. Morgan is a dentist who has had over 30 years of experience in diagnosing and treating people with TMJ and related problems. (Note 5) . He has written many articles over a 25 plus year period, two editions of a textbook published by C. V. Mosby and Quintessence, and translated into three languages (Spanish, German, Japanese). These books are used in post-graduate training (Note 6) . He has taught post-graduates at the University of California at Irvine School of Medicine for 20 years. He has been on the faculty of Loma Linda University School of Dentistry, and directed their first TMJ clinic. He treats 90% of his patients non-surgically. For some people, however, a surgery is required to repair the joint. Dr. Morgan has an 85% success rate. There are long term studies in the medical and dental literature documenting this success rate (Note 7) .

Through his research of over 30 years, he has found that besides pain and dysfunction of the TMJ, ear and related symptoms can occur. He is the only individual who has documented the effects of TMJ treatment on ear symptoms such as subjective hearing loss, tinnitus, vertigo, etc. (Note 8) . in the medical and dental literature. He is doing clinical research at present on the relationship of the TMJ to Hyperacusis, Fibromyalgia, and Chronic Fatigue Syndrome.

He is the founder and president of the TMJ Research Foundation, a non-profit corporation approved by the dental and medical boards to give post-graduate training in diagnosis and treatment of TMJ problems, which has been in existence for over 25 years. Besides the USA, the Foundation has given courses in Europe, Asia, and South America. He is a Founding Fellow of the International College of Cranio-Mandibular Orthopedics. He is the founder of the TMJ Clinic at the White Memorial Medical Center in Los Angeles. The California State Dental Board has approved this clinic for training of dentists in the TMJ field. As a result of his writings on TMJ implants in the scientific literature (Note 9) . as well as the courses he has given warning of the dangers in using the wrong type of implant, he was asked to be a consultant to the FDA on TMJ surgical implants. He was responsible in part for the removal of the Vitek-Kent Proplast-Teflon implant system from the market.

His surgical team in California specializes in repairing/replacing tempormandibular joints after they have been damaged by multiple surgical procedures, including alloplastic and natural tissue implants. In some individuals, the implants of Dr. Morgan's design and preference of material have been in use for over 30 years. The implant system he uses has received Pre-amendment Device Status from the FDA. There are many long-term studies attesting to the efficacy, biocompatibility, and durability of these implants (Note 10) . The non-surgical treatment he applies, most successfully uses sophisticated diagnostic instrumentation. Complete and accurate diagnosis is the most important part of treating the TMJ patient.

How many referenced publications?

Twenty referred publications on the TMJ and related structures, two editions of a text book on the TMJ apparatus. At present he is working on the third edition of that textbook.
