摘　　要：目的:探讨微型支抗种植体压低上前牙改善露龈笑的临床效果。方法:随机将2021年5月—2023年5月广东祈福医院收治的70例凸面畸形患者分为对照组和观察组,每组各35例。对照组予以多用途弓压低上前牙治疗,观察组予以微型支抗种植体压低上前牙治疗。比较两组矫治有效率,治疗前及治疗3个月后垂直露龈量、Overbite、UL-UI变化,以及上前牙压低长度、牙冠长度与矫正前变化差值等。结果:观察组的矫治有效率为94.29%,比对照组高(P<0.05)。治疗后两组垂直露龈量、Overbite及UL-UI值均较治疗前下降,且观察组低于对照组(P<0.05)。观察组上前牙压低长度,中切牙、侧切牙、牙尖与矫正前变化差值均大于对照组(P<0.05)。结论:相比多用途弓压低上前牙治疗,采用微型支抗种植体压低上前牙治疗可以更好改善露龈笑,提高矫治有效率,值得应用推广。Objective:To investigate the clinical effect of microanchorage implants on improving gingival laughter by pressing the anterior teeth.Methods:70 patients with gingival laughter admitted to Clifford Hospital in Guangdong Province from May 2021 to May 2023 were randomly divided into control group and observation group,with 35 cases in each group.The control group was treated with multi-purpose bow compression,and the observation group was treated with micro anchorage implant compression.The effective rate,the changes of vertical gingival volume,Overbite,UL-UI,and the difference of anterior compression length and crown length between the two groups before treatment and 3 months after treatment were compared.Results:The effective rate of correction in observation group was 94.29%,higher than that in control group(P<0.05).After treatment,the vertical gingival volume,Overbite and UL-UI values of the two groups were decreased compared with those before treatment,and the observation group was lower than the control group(P<0.05).In the observation group,the lower anterior tooth length,the difference between the central incisor,lateral incisor and cusp before correction were greater than those in the control group(P<0.05).Conclusion:Compared with multi-purpose bow compression of anterior teeth,micro-anchorage implants can better improve the gingival smile and improve the efficiency of correction,which is worthy of application and promotion.
