正颌外科联合正畸治疗安氏Ⅰ类双颌前突畸形

Combined Orthodontics and Orthognathic Surgery for Correction of Bimaxillary Prognathism Deformity with Skeletal Class Ⅰ Malocclusion

目的探讨上颌前部骨切开术和下颌前部根尖下骨切开术联合正畸治疗在矫治安氏Ⅰ类双颌前突畸形中的应用。方法对78例安氏Ⅰ类双颌前突畸形患者进行正畸正颌外科联合治疗。全部患者均行上下颌前部骨切开、骨块后退术，其中22例同期行颏前徙成形术。结果78例患者伤口均一期愈合，无感染及骨块坏死。术后随访12～36个月，2例术后1—2个月出现轻度复发。所有患者治疗结束后，颌骨关系正常，牙弓形态及胎曲线正常，牙排列整齐，咬合关系良好，颜面外形明显改善，疗效满意。结论应用上颌前部骨切开术和下颌前部根尖下骨切开术联合正畸治疗安氏Ⅰ类双颌前突畸形患者，可取得咬合关系和颜面外形俱佳的疗效。

Objective To study the application of combined orthodontics and anterior maxillary osteotomy and anterior mandibular subapical osteotomy for correction of bimaxillary prognathism deformity with skeletal Class Ⅰ malocclusion. Methods Seventy-eight patients with bimaxillary prognathism deformity with skeletal Class Ⅰ malocclusion were undergone combined orthodontics and orthognathic surgery. All cases were undergone anterior maxillary osteotomy and anterior mandibular subapical osteotomy, 22 cases were simultaneously undergone genioplasty to advance their chins. Results All wounds healed well,there was no serve complication. The clinical follow-up period ranged from 12 to 36 months. After joint orthodontics and orthognathic surgery, all patients regained satisfactory face appearances and function. Conclusion Bimaxillary prognathism deformity with skeletal Class Ⅰ malocclusion could be satisfactorily corrected by combined orthodontics and anterior maxillary osteotomy and anterior mandibular subapical osteotomy.
