摘　　要：目的分析外科导萌联合正畸矫治治疗小儿上颌前牙埋伏的效果。方法 50例上颌前牙埋伏阻生患儿随机分为对照组与观察组各25例。对照组开展外科导萌治疗,观察组开展外科导萌联合正畸矫治治疗。比较2组的治疗效果和并发症。结果观察组埋伏牙萌出率显著高于对照组,萌出时间显著短于对照组(P<0.05);观察组一次手术正常率显著高于对照组,二次手术率显著低于对照组(P<0.05);观察组牙列紊乱率、牙髓坏死发生率均显著低于对照组(P<0.05)。2组牙龈退缩率无显著差异(P>0.05)。结论外科导萌联合正畸矫治治疗小儿上颌前牙埋伏的效果显著。Objective To analyze the clinical effect of surgical guiding eruption combined with orthodontic correction on the treatment of children with ambush of maxillary anterior teeth.Methods Fifty children with impacted ambush of maxillary anterior teeth were selected and randomly divided into control group and observation group,25 cases in each group. The control group was treated with surgical guiding eruption,and the observation group was treated with guiding eruption combined with orthodontic treatment. The effect and complications were compared between the two groups. Results The eruption rate of the embedded teeth in the observation group was significantly higher than that in the control group,and the eruption time was significantly shorter than the control group（ P〈0. 05）. The normal rate by one operation in the observation group was significantly higher than that of the control group,and rate of the secondary operation was significantly lower than the control group（ P〈0. 05）. The incidence rates of dentition disturbance and pulp necrosis in the observation group were significantly lower than those in the control group（ P〈0. 05）. There was no significant difference in the rate of gingival recession between the two groups（ P〉0. 05）. Conclusion Surgical guiding eruption combined with orthodontic treatment is effective in the treatment of children with ambush of maxillary anterior teeth.
