Synopsis: The masticatory system functions in a complex, integrated, orthopedic manner. Many different philosophies regarding occlusal function are espoused. It is recognized that long-term orthopedic stability is dependent on the harmonious function of the dentition, hard and soft tissue supporting structures, temporomandibular joint complexes and the neuromuscular systems of the head and neck. A detailed analysis of the various components with an understanding of anatomy, physiology and neural pathways facilitates case specific diagnosis and management. Physiologic occlusal function is recognized to be a key component of orthopedic stability of the masticatory system. A causal relationship between mechanical stresses such as those associated with occlusal parafunction (clenching/ bruxing) has been suggested by many. As forces enter the masticatory system they are dissipated through many structures including the temporomandibular joint complex, in some cases resulting in maladaption and/or pathology. This presentation will include a recommended protocol for patient evaluation. Molecular biological factors currently recognized to result from excessive mechanical stresses applied to these structures will be highlighted. Proposed etiologic and maintaining factors of subgroups of temporomandibular disorders and their management will be discussed. This course will provide information to help: Understand the basic principles of anatomy and function of the masticatory system Recognize the clinical signs/ symptoms of maladaptive occlusion Understand the dentist’s role in the diagnosis and management of sleep disturbances, specifically nocturnal bruxism Better appreciate the role of occlusal orthoses in patient care

Dr. Henry A. Gremillion is a 1977 graduate of LSU School of Dentistry. He maintained a private general dental practice in Cottonport, Louisiana from 1977 to 1989. He then completed a 2 year Fellowship in Craniofacial Pain and Dysfunction at the University of Florida College of Dentistry under the mentorship of Dr. Parker E. Mahan.

He served as director of the Parker E. Mahan Facial Pain Center and directed a fellowship program in orofacial pain from 1992-2008 and was on the active dental staff of Shands Teaching Hospital during that period. While at UFCD he served as the P. E. Mahan Endowed Professor in Orofacial Pain in the Department of Orthodontics and held an affiliate appointment in the Department of Prosthodontics at the UFCD.

He is the recipient of the 2008 Academy of General Dentistry’s Thaddeus V. Weclew Award for contributions to the art and science of dentistry. He received the Dawson Academy Career Service Award in February 2009. In October 2008 he was named Dean of LSU School of Dentistry. He serves as a consultant in the field of temporomandibular disorders and orofacial pain for the U.S. Army, U.S. Navy, U.S. Air Force, Veteran's Administration Hospital in Gainesville, FL., ADA Council on Dental Practice, and the Comprehensive Dentistry Program at UFCD.

He is an associate faculty member of the Dawson Academy for Advanced Dental Study. He also serves on the editorial boards of the Journal of Prosthetic Dentistry, Journal of Craniomandibular Practice, and Journal of the Academy of General Dentistry. He has lectured extensively in the U.S. and abroad and has authored/co-authored numerous scientific articles, abstracts, and book chapters. His research interests include temporomandibular disorders, bruxism, and psychosocial aspects of orofacial pain. His major clinical interest is the diagnosis and management of orofacial pain.
