It is said that mandibular prognathism is one of the most common jaw deformities in Japan. The patients with mandibular prognathism present two different types of occlusal disharmony directly relatetd to facial appearance. The first type includes patients with dental protrusion. In this case, the orthodontist usually is able to provide adequate orthodontic correction, and, following occlusal correction, the soft tissue contur of the face usually is also improved. When favorable growth and development of the face occur concurrently, the improvement in facial balance and disharmony is dramatic and pleasing. The second type, in contrast, includes occlusal and gnathic disharmony that is the result of facial maldevelopment. Most deformities involving the lower third of the face are reflected to some extent in the dentition. The resultant malocclusion and facial disfigurement are generally too severe to be corrected solely by ordinary orthodontic procedures. Then the treatment indicates orthognathic surgery which makes satisfactory jaw and occlusal relationships by the oral surgeon, before and after operation, in conjunction with the orthodontist and other dental specialists for the best results to be obtained. The orthoganthic surgery in the Second Department of Oral Surgery, Fukuoka Dental College, was started since 1977, and 56 patients have been operated on for mandibular prognathism. Here, the flow of our present treatment with the joint efforts of oral surgeon and orthodontist has been summarized, and 7 cases of mandibular prognathism treated have been presented.
