Rheumatoid disease and related arthropathies. II. Surgical rehabilitation of the temporomandibular joint.

A new classification of four types of TMJ involvement is proposed to help orient and direct the medical and surgical treatment of patients with rheumatoid disease and related arthropathies. Clinical symptoms, radiographic findings, facial deformity features, treatment planning, and results are discussed, with case reports that illustrate each type. Interpositional polymer laminates, a new glenoid fossa prosthesis, and a metallic condyle are introduced for use in selected cases where erosion and destruction of the condyle, meniscus, and fossa area have produced significant TMJ dysfunction and occlusal-facial deformity.
