The temporomandibular joint is a highly complex joint composed of articular disc. The disc of the TMJ is surrounded by a special fluid called synovial fluid. This provides the articular disc with a milieu to keep it intact. Once the articular disc erodes, little can be done to protect the interaction between the temporomandibular joint and the skull. There are 3 ligaments associated with the joint called the temporomandibular ligament, the stylomandibular ligament and the sphenomandibular ligament. These ligaments serve to keep the joint in place.
