Alloplastic Total TMJ Replacement

Alloplastic total TMJ replacement aims to reduce pain, improve jaw function, correct occlusion and facial deformity, and improve quality of life. Modern implant design, materials, and biomechanical understanding have improved the safety and effectiveness of TMJ replacements. TMJ total joint replacement procedures in the United States increased by 38% from 2005 to 2014. The procedure replaces the condylar head and temporal fossa with alloplastic components. Alloplastic total TMJ replacement is used for severe temporomandibular disorders that do not respond to conservative treatment and for reconstructing congenital or acquired TMJ defects.
