Abstract

Mandibulectomy and commando procedures involve the extensive loss of tissues and associated functions. Swallowing, speech, mandibular movements, mastication, control of saliva, respiration, and psychic functioning are adversely affected by radical mandibular surgery. The treatment of any maxillofacial patient is enhanced by careful preoperative evaluation. Clinical and radiographic examinations, including diagnostic casts, allow the prosthodontist to discuss the potential rehabilitative needs with the surgeon. The course of rehabilitation is associated with the location and extent of the lesion and the anticipated surgical management, and it is improved by early prosthodontic evaluation and treatment. Gross facial disfigurement and impaired mandibular function may result when the extent of surgery interrupts mandibular continuity. Maintaining continuity helps preserve normal muscle function and facial contours and leads to a more predictable and favorable prosthodontic treatment. The degree of success is related to the location and extent of the mandibular resection, the amount of adjacent soft tissue removed during surgery, and presence or absence of natural teeth. Retainers are probably the most important components contributing to the success of the prosthesis.
