Abstract: A temporomandibular joint replacement system includes a condylar component secured with a mandibular bone and a fossa component with a fossa backing secured with a zygomatic bone and slidably attached with a removable fossa lining, the fossa lining having an open-ended concave fossa dome with a post-center peak to allow for mediolateral and anterior translation with a rounded, oblong condylar head of the condylar component. The slidable attachment mechanism of the fossa backing and fossa lining is laterally-oriented to allow for post-implantation removal and replacement without disturbing any bone or bone-interfacing components. The bone-interfacing surfaces are anatomically-contoured to their respective bone surfaces and formed with materials and textures which promote osseointegration with the joint replacement.
