摘　　要：目的:观察上颌埋伏阻生前牙应用固定正畸方法进行矫治的临床疗效,探讨埋伏阻生前牙有效的治疗方法。方法:对49例58颗上颌前牙埋伏阻生病例,应用固定正畸进行矫治,结合牙槽外科开窗术,对埋伏牙进行牵引。其中20颗进行开拓间隙使之自然萌出,38颗进行开窗封闭式牵引导萌矫治。结果:55颗阻生牙矫治后牙髓活力正常、未见埋伏牙及邻牙牙根吸收、牙周组织正常。开窗封闭式牵引导萌有3颗牙治疗失败,总体成功率94.8%。结论:应用固定正畸技术开拓间隙或结合牙槽外科开窗术导萌埋伏阻生牙,可有效保存上颌埋伏阻生前牙。Objective：To evaluate the results of treating anterior impacted teeth by fixed orthodontic treatment.Method：49 cases of impacted upper anterior teeth were treated with fixed orthodontic treatment,with or without fenestration.20 cases just by open space and erupted by themselves,29cases were pulled in the bone.Result：When the treatment completed,the tooth pulp vitality of impacted teeth were normal,no inpacte teeth or adjacent tooth had root resorption,and the periodontal tissues of impacted teeth were normal.Conclusion：The impacted upper anterior teeth can be treated by fixed orthodontic treatment,with or without fenestration.
