Abstract

Temporomandibular Joints (TMJ) is a bilateral fibrocartilage joint. This joint is unique in that it is a bilateral joint that functions as one unit. As with the other joints, many conditions affect TMJ causing It not to do its tasks. These conditions are ankylosis, arthritis, trauma, congenital abnormalities, pathologic diseases, and chronic dislocation. Although as a rule less is often best in treating Temporomandibular disorder (TMD) sometimes it is necessary to use invasive modalities. Total mandibular joint replacement (TMJR) is one of them that has been in use since 1963 and has been developed since. It is used in End-stage TMJ diseases resulting in anatomical architectural form distortion and physiological dysfunction dictates the need for reconstruction. Although nowadays the use of TMJ prosthesis is popular, sometimes it has catastrophic results due to its complications. If there is no indication, this method may cause legal issues. This article provides an overview of the clinical indications and contraindications associated with the TMJR and outcomes for our custom TMJ prosthesis cases are presented.
