Temporomandibular ankylosis is an extremely disabling condition from the view point of function, hygiene and cosmetic appearance. The major etiologic factors of temporomandibular ankylosis are trauma and infection and it may affect general health and mental status and may make oral hygiene and dental care impossible. The earlier the ankylosis, the greater is the deformity of the face. The deformity occurs due to the physical damage to the growth center of the condyle and loss of functional movements of the mandible, which stimulates its growth. Tomograms and panoramic radiographs are invaluable diagnostic aids and scintigram and EMG were also used for diagnosis. This is a case of unilateral TMJ ankylosis associated with mandibular micrognathia in a 16 year old Korean man, which is corrected by arthroplasty with acrylic resin implant and horizontal advancement genioplasty. On postop. 3rd day, mechanotherapy was begun using the prefabricated acrylic splint with screw for mouth opening. Postoperative results were good both functionally and esthetically.
