Abstract: Objective To investigate the observation on the curative effect of orthodontic forced eruption on children with embedded anterior maxillary teeth. Methods 100 children with embedded anterior maxillary teeth in the hospital from January 2014 to January 2017 were divided into control group and observation group by random number table, with 50 cases in each group. Control group underwent conventional eruption operation, and observation group was treated with eruption operation and orthodontic correction. The dental function, rate of dentition disorder, rate of pulp necrosis and satisfaction were compared between two groups. Results After treatment, the scores of swallowing function(t=4.119,P=0.000), masticatory function(t=4.897,P=0.000) and language function（t=5.828,P=0.000) in observation group were higher than those in control group, and the differences were statistically significant. After treatment, the rate of dentition disorder and rate of pulp necrosis in observation group [2.00% (1/50), 4.00% (2/50)] were lower than those in control group [16.00% (8/50), 18.00% (9/50)], and the differences were statistically significant (P<0.05). After treatment, the satisfaction of observation group [96.00% (48/50)] was higher than that of control group [80.00% (40/50)], and the difference was statistically significant (P<0.05). Conclusion Orthodontic correction in adjuvant treatment of children with embedded anterior maxillary teeth can decrease the rates of dentition disorder and pulp necrosis, improve dental function and satisfaction.

摘要： 目的 探讨正畸辅助导萌手术治疗儿童上颌前牙埋伏阻生的疗效观察。方法 选取2014年1月~2017年1月在我院就诊的小儿上颌前牙埋伏阻生患者100例,采用随机数字表法分为对照组与观察组,每组各50例。对照组行常规外科导萌手术治疗,观察组行常规外科导萌手术联合正畸矫治辅助治疗,比较两组牙齿功能、牙列紊乱率及牙髓坏死率及满意度。结果 治疗后,观察组吞咽评分(t=4.119,P=0.000）、咀嚼评分（t=4.897,P=0.000）以及语言功能评分（t=5.828,P=0.000）均高于对照组,差异有统计学意义;观察组治疗后牙列紊乱率为2.00%（1/50）,牙髓坏死率为4.00%（2/50）,均低于对照组的16.00%（8/50）、18.00%（9/50）,差异有统计学意义(P<0.05);治疗后,观察组满意度为96.00%（48/50）,高于对照组的80.00%（40/50）,差异有统计学意义（P<0.05)。结论 正畸矫治辅助治疗可降低小儿上颌前牙埋伏阻生患儿牙列紊乱及牙髓坏死率,改善牙齿功能以及满意度。
