TEMPOROMANDIBULAR JOINT IMPLANTS AND METHODS OF TREATING A TEMPOROMANDIBULAR JOINT

摘要

The present disclosure provides intramedullary mandibular implants for the temporomandibular joint. The mandibular implants include a stem portion, a collar portion and a head portion. The stem, collar and head portions may be integral. The stem portion may define an inferior end and the head portion may define a superior end of the implants. The head portion may be arcuate in the sagittal plane to provide an articulating surface with a fossa or a fossa component. The collar portion may be intermediate of the head and stem portions and form a channel between an interior surface of the collar portion and an exterior surface of the stem portion. In use, the stem portion may be implanted within a condyle of a mandible such that an end portion of the condyle is situated within the channel of the implant and the head portion articulates with the fossa or fossa component.
