Temporomandibular disorder (TMD) is a multifactorial disease process caused by muscle hyperfunction or parafunction, traumatic injuries, hormonal influences, and articular changes. Symptoms of TMD include decreased mandibular range of motion, muscle and joint pain, joint crepitus, and functional limitation or deviation of jaw opening. Only after failure of noninvasive options should more invasive and nonreversible treatments be initiated. Treatment can be divided into noninvasive, minimally invasive, and invasive options. Temporomandibular joint replacement is reserved for severely damaged joints with end-stage disease that has failed all other more conservative treatment modalities.
