Overview
Total TMJ reconstruction consists of replacing the articulating surfaces of both the glenoid fossa of the temporal bone and the mandibular condyle.
Indications
Ankylosis, degenerated or resorbed joints with severe anatomic abnormalities, severe inflammatory joint disease such as rheumatoid arthritis, and failed alloplastic bone graft procedures. Total joint replacement is an end-stage procedure, and is only indicated when all other treatments and procedures have failed.
Precautions
Due to the complex nature of TMJ function, it is extremely difficult to reconstruct any joint to its normal pre-operative function. Pain relief gained is often a secondary benefit, and quite often these patients require co-management with either pharmaceuticals or other mechanical devices—either long- or short-term.
