Prostheses, Joint, Temporomandibular, Total
Definition : Implantable prostheses designed for total replacement of the temporomandibular joint. These prostheses typically consist of both a mandibular fossa component (consisting of a plastic [e.g., polyethylene] fossa bearing that may include a titanium mesh backing, also known as fossa eminence prosthesis [FEP]) and a mandibular condyle component intended to replace the mandibular condylar head and to articulate with the mandibular fossa component; they may include an intra-articular disc as a separate component. Total temporomandibular joint prostheses are used in patients who suffer from osteoarthritis, rheumatoid arthritis, congenital malformations, or neoplasms, as well as after trauma (e.g., fracture).
