temporomandibular joint
modified hinge type of synovial joint, condyle of mandible articulates with the articular tubercle and mandibular fossa of temporal bone. Fibrous joint capsule loosely attaches to articular margins of the temporal bone and around neck of the mandible. joint is divided into 2 parts, superior and inferior compartments by articular disc
TMJ disorder characteristics
pain in jaw and face, altered movement of mandibular condyle in fossa or against cartilaginous disc
TMJ disorder treatments
oral analgesics or corticosteroid injection, oral appliance, surgery
