This is a case report of mandibular prognathism with multiple missing teeth which showed more difflculties of mastication due to severe malocclusion and facial disfigurements,but well treated with the intraoral sagittal split osteotomy in the rami. The postoperative conditions about esthetics as well as occlusal pattern and masticatory efficiency were improved owing to model analysis and occlusal adjustment on an atomic articulator,cephalometric analysis of hard and soft tissue and relapse control by activator and chin cap. The results are as follows; 1. It is very required for the mandibular prognathism with missing teeth that careful diagnosis and treatment planning should be made using an anatomic articulator, and that preoperative condylar guidance and incisal guidance must be recorded for the purpose of postoperative full mouth rehabilitation. 2. The intermaxillary rubber elastic traction as well as Activator and chin cap application were more effective manners for the correction of occlusal relapse that occurred after the removal of intermaxillary fixation devices. 3. The further cooperative studies of the department of oral and maxillofacial surgery, orthodontics, prosthetics and periodontology were much necessary to improve the masticatory function and esthetics in spite of inevitable occlusal and esthetic relapse after orthognathic surgery of mandibular prognathism.
