微种植体支抗与传统支抗在安氏Ⅱ类错牙合畸形矫治中的应用效果观察

Application Effects of Orthodontic Micro-implant Anchorage and Traditional Anchorage in Correcting Angle ClassⅡMalocclusion

目的:观察微种植体支抗与传统支抗在安氏Ⅱ类错牙合畸形矫治中的应用效果。方法:回顾性分析笔者医院2017年5月-2022年5月收治的安氏Ⅱ类错牙合畸形患者的临床资料,按照性别、年龄1:1分组原则将80例患者分为两组,每组40例。对照组采取传统支抗治疗,观察组采取微种植体支抗治疗。比较两组治疗前后的临床疗效、矫治效果主观评价、头影测量值及治疗后的并发症发生率。结果:治疗后,观察组患者上中切牙凸距差、上中切牙倾角差明显高于对照组,磨牙位移明显小于对照组(P<0.05);观察组矫治效果主观评价的舒适性、依从性、顺利性评分均高于对照组(P<0.05);观察组患者上下颌齿槽座角差(ANB)、下齿槽座角(SNB)、上齿槽座角(SNA)水平明显低于对照组(P<0.05);观察组患者并发症发生率为5.00%,明显低于对照组的20.00%(P<0.05)。结论:与传统支抗治疗相比,微种植体支抗对安氏Ⅱ类错牙合畸形患者疗效较好,能缓解患者局部牙周严重反应,减少治疗后并发症发生概率。

Objective The aim of this study was to observe the application effects of orthodontic micro-implant anchorage and traditional anchorage in correcting Angle ClassⅡmalocclusion.Methods The clinical data of 80 patients with Angle ClassⅡmalocclusion who were admitted to the hospital from May 2017 to May 2022 were analyzed retrospectively.The patients were assigned to two groups according to gender and age,with 40 cases in each group.Patients in the control group were treated with traditional anchorage,and those in the observation group were treated with orthodontic micro-implant anchorage.Clinical efficacy,subjective correction effect,cephalometric measurements and the incidence of complications were compared between the groups.Results After treatment,the upper central incisor protruding distance and angle difference in the observation group were significantly larger,and molar displacement was significantly smaller when compared with those in the control group(P<0.05).The observation group had higher scores than the control group in terms of comfort level,compliance and correction(P<0.05).The point A nasion point B(ANB)angle,the sella-nasion-point B(SNB)angle and the sella-nasion-point A(SNA)angle in the observation group were significantly smaller when compared with those in the control group(P<0.05).The incidence of complications in the observation group(5.00%)was significantly lower than that in the control group(20.00%)(P<0.05).Conclusion Compared with traditional anchorage,orthodontic micro-implant anchorage is more effective in the treatment of patients with Angle ClassⅡmalocclusion.The latter can relieve local severe periodontal reactions,and reduce complications after treatment.
