The goal of surgical-orthodontic treatment of mandibular prognathism is to achieve maximum function, esthetics and stability. These objectives were achieved in 10 adults who manifested a specific type of mandibular prognathism. The patient group under study, who manifested a relatively contour deficient chin and prominent lower lip, and class III malocclusion, was treated by orthodontics and mandibular setback in concert with advancement genioplasty. The advancement genioplasty technique was accomplished by maintaining as much soft tissue pedicle as possible to the repositioned chin. A near one-to-one ratio of soft tissue-to-osseous change was achieved in the patient group under study with the use of the described genioplasty technique in combination with mandibular setback by intraoral vertical ramus osteotomies.
下颌前突的外科正畸治疗目标是实现最大程度的功能、美观和稳定。10名表现出特定类型下颌前突的成年人实现了这些目标。所研究的患者群体表现出相对轮廓不足的下巴和突出的下唇，以及III类错牙合，通过正畸和下颌后缩并配合颏成形术进行治疗。颏成形术通过尽可能多地保留软组织蒂至重新定位的下巴来完成。在所研究的患者群体中，通过使用所描述的颏成形术技术并结合经口垂直升支截骨术进行下颌后缩，实现了软组织与骨组织变化接近一对一的比例。
