title: Treatment of protracted bilateral mandibular dislocation with Proplast-Vitallium prostheses.
abstract: A case of bilateral protracted mandibular dislocation complicated by the presence of unusual degenerative changes in the temporomandibular joints is presented. A synopsis of treatment modalities that have been used previously to treat similar conditions is given. Our treatment consisted of bilateral condylectomies, eminectomies, and insertion of Proplast-coated Vitallium condylar prostheses. These procedures resulted in the re-establishment of normal TMJ anatomy, the maintenance of proper posterior mandibular vertical dimension, correction of malocclusion, and relief of the patient's symptoms.
