Disorders of the temporomandibular joint (TMJ) are widespread, afflicting between 5 and 40 percent of the adult population. TMJ disorder (TMJD) encompasses several conditions including orofacial pain, restricted mandibular movement, clicking and popping sounds from the jaw joint, and locked jaws. About 10 to 15 percent of TMJD patients have osteoarthritis, characterized by a degenerative joint which results from erosion of articular cartilage and degeneration of subchondral cortical and trabecular bone. Symptoms can become chronic and difficult to manage, severely reducing quality of life.
