Condylar replacement alone is not sufficient for prosthetic reconstruction of the temporomandibular joint.
Prosthetic reconstruction of the temporomandibular joint (TMJ) is a controversial method of treatment. This paper presents 2 cases that illustrate the problem with prosthetic reconstruction of the condylar head with no fossa reconstruction. In both cases, severe erosion and heterotopic bone formation occurred, and the patients underwent installation of total TMJ prostheses to replace the previous, partial ones.
