Orthognathic surgery in conjunction with fixed orthodontics is a common indication for interdisciplinary management of severe skeletal Class III malocclusion. A thorough analysis of pretreatment investigations and development of a surgical visual treatment objective is essential to plan the type of surgical technique required. Bimaxillary orthognathic surgery is the most common type of surgical procedure for severe skeletal discrepancies. The present case report is a combined ortho-surgical team management of a skeletally Class III patient. The severity of the case required bilateral upper first premolar extraction for dentoalveolar decompensation and simultaneous "Two-jaw surgery" with maxillary advancement of 4 mm and mandibular setback of 7 mm. Postsurgery, a pleasing good facial profile was achieved with Class II molar relation and positive overjet.
正颌外科手术联合固定正畸治疗是严重骨性III类错牙合畸形多学科治疗的常见适应证。对术前检查进行全面分析并制定手术视觉治疗目标对于规划所需的手术技术类型至关重要。双颌正颌外科手术是治疗严重骨骼差异最常见的手术方式。本病例报告为一个骨性III类患者的正畸 - 外科联合团队治疗。该病例的严重程度需要拔除双侧上颌第一前磨牙以进行牙槽骨代偿，并同时进行“双颌手术”，上颌前徙4mm，下颌后退7mm。术后，实现了令人满意的良好面部轮廓，磨牙关系为II类，覆盖为正值。
