摘　　要：目的探讨外科正牙术治疗成人前牙列畸形的临床效果。方法在局麻下采取牙间骨切开、牙根尖上0．5cm处横截骨的带软组织蒂的牙骨块移植法，共手术矫正了21例成人前牙列畸形患者，其中男13例、女8例，年龄21-44岁，平均32．5岁。手术涉及牙位数73颗（中切牙42颗、侧切牙24颗、尖牙7颗）。并对21例患者分别进行了3个月、6个月、1年、或1年以上的随访观察。结果术后随访观察见1例发生感染（局部炎性肉芽形成，约占4．8％），1例（1颗牙）前突复发（占病例数的4．8％，占牙位数的1．4％），2例（5颗牙）发生牙髓坏死（占病例数的9．5％，占牙位数的6．8％），但所有患者的前部牙列畸形状况均得到了较为明显的改善。结论外科正牙术治疗成人前牙列畸形的手术效果满意，可作为不适宜常规正畸的成人患者的治疗方法。Objective To discuss the effect of surgical orthodontics for malformation of adult foreteeth. Mechods Under local anesthesia, an incision was made into the bone where the tooth was embedded, and a bone with soft tissue was transplan- ted 0.5cm above the root of the tooth. 21 adults whose foreteeth were malformed ubderwent the operations. Among them, 13 were male and 8 were female,ranging between 21 -44 in age. The operations involved 73 teeth（42 central incisors, 24 lateral incisors,7 canine）. The 21 patients were observed after operation for 3 months, 6 months, 12 months or longer. Results The observation found 1 case of inflammation （local inflamed acestoma, 4.8% of all samples）, 1 case of （1 teeth） protrusion re- currence （4.8% of all samples, 1.4% of all teeth）, 2 cases of（5 tooth） dental pulp putrescence（9.5% of all samples, 6. 8% of all teeth ）. For all samples, the statuses of malformation of foreteeth were improved. Conclusion The results of sur- gical orthodontics for malformation of foreteeth are satisfactory. Surgical orthodontics can be adopted for malformation of the adult foreteeth which the normal orthodontics can not be adopted.
