 note = {application/pdf, Surgical corrections were performed on prognathism in 17 patients who were examined during the past 8 years in our department. The purpose of this study was to investigate the predominant cases of mandibular prognathism corrected by use of the Dal Pont-Obwegeser method, and to determire whether or not the period of preoperative orthodontic treatment, occlusion, particularly open bite, method of immobilisation, and rotation or displacement of condyle may considerably influence the prognosis (such as return to preoperative relationship). In conclusion, the Dal Pont-Obwegeser method was useful in achieving esthetic appearance, correct occlusion and proper function of the mandible. There have been no open bites nor relapse to date. However, open bite in preoperative relationship tended to intimate incisal occlusion within one year after the removal of arch bars and intermaxillary elastics or wires. A balanced occlusion in harmony with the restored masticating mechanism may not be easily established in open bite. Therefore stabilization may be necessary to be left for a period of more than one year namely critical period to arise postoperative complications. Arthrose was not observed even in cases in which the condyle was thought to be rotated, as the length of reduction to distal position was different on both sides, and radiography revealed a little dislocation of the position of condyle in mandibular fossa. In spite of the extreme care taken to not traumatize the inferior alveolar neurovascular bundle, numbness of one or both sides of the lower lip appeared in many cases, but it was not persistent anesthesia. These findings are of benefit to orthodontic and surgical cooperation in the treatment of cases of prognathism.},
