ABSTRACT

The Christensen TMJ implant is often used clinically as a total joint replacement of the temporomandibular joint. The system consists of a thin fossa component and a condylar component with a polished articular head. In this study, we analyzed the surface finish and the metal structure of the components. We also measured the contact areas between the two components for different load levels. Such information may be useful in evaluating clinical performance as well as in making future improvements in the design of these implants.
