Prostheses, Joint, Temporomandibular
Definition : Implantable prostheses designed for total or partial replacement of the temporomandibular joint. Partial temporomandibular prostheses are mandibular fossa components intended to provide an articulation surface for the mandibular condyle; they usually consist of a plastic (e.g., polyethylene) fossa bearing that may include a titanium mesh backing (sometimes called fossa eminence prosthesis [FEP]). Mandibular condyle partial temporomandibular prostheses are intended to replace the mandibular condylar head and to articulate with the mandibular fossa component; they are used almost exclusively in combination with a mandibular fossa component in total temporomandibular prostheses. Intra-articular partial temporomandibular prostheses are intended to replace the disc of fibrocartilage attached to the mandibular condyle by ligaments. Total temporomandibular joint prostheses typically include mandibular fossa and mandibular condyle components. Temporomandibular joint prostheses are intended for patients who suffer from osteoarthritis, rheumatoid arthritis, congenital malformations, or neoplasms, as well as after trauma (e.g., fracture).
