Subluxation of the temporomandibular joint.
The temporomandibular joint in actual function does not resemble other joints in the body in that the condyles leave their fossae with maximal opening and in some subjects with only a 35 mm. opening. The term subluxation, with its implication of abnormality, does not seem applicable to a normal movement. While significant problems, such as dislocation, locking, and loud clicking, can occur with such anterior-to-the-fossae movements, they are relatively rare. Most temporomandibular problems are associated with confinment of the condyles to their fossae with limited or no translatory condylar movement. A recognition of the normal range of condylar movement would lessen iatrogenic abuse of this area.
