摘要
There is provided a prosthesis for the replacement of a temporomandibular joint having a mandible and a temporal bone. The prosthesis comprises a condylar component for fastening to the mandible, the condylar component including a condylar head having a convex spherical articular surface; and a fossa component for fastening to the temporal bone, the fossa component having a concave spherical articular surface defining a socket being operable to engage the condylar head in an articulating manner wherein the concave spherical articular surface traverses through approximately 180°. The fossa component may also be anteroposteriorly symmetric.
