摘 要:目的:探究微种植体支抗加直丝弓矫治技术治疗错[牙合]畸形的正畸效果及对颌面部美观的影响。方法:选取2020年3月-2021年3月笔者医院接诊的126例错[牙合]畸形患者作为观察对象,采用分层随机化法分为观察组和对照组,每组63例。其中对照组给予传统直丝弓矫治技术+口外弓支抗治疗,观察组使用传统直丝弓矫治技术+微种植体支抗治疗。比较两组治疗后12个月的正畸效果(磨牙位移、切牙凸距差、切牙倾斜角差、矫治时间),对比两组患者治疗前、治疗后12个月的硬组织形态指标[鼻根点与上齿槽点连线与前颅底面的夹角(Sella-nasion subspinale angle,SNA)、鼻根点与下齿槽点连线与前颅底面的夹角(Sella-nasion supramental angle,SNB)、上齿槽座点-鼻根点-下齿槽座点的夹角(Subspinale-nasion supramental angle,ANB)],牙周指标[牙龈指数(Gingival index,GI)、牙菌斑指数(Dental plaque index,PLI)、龈沟出血指数(Sulcus bleeding index,SBI)、附着丧失指数(Clinical attachment loss index,CAL)]及口腔功能(咀嚼效率、咬合力)的变化。结果:治疗后12个月,观察组磨牙位移显著短于对照组,切牙凸距差、切牙倾斜角差显著大于对照组(P<0.05),矫治时间短于对照组(P<0.05);治疗后12个月,两组SNA、ANB、GI、PLI、SBI、CAL均明显降低,且观察组显著低于对照组(P<0.05),两组SNB、咀嚼效率、咬合力均明显升高,且观察组显著高于对照组(P<0.05)。结论:微种植体支抗加直丝弓矫治技术应用于错[牙合]畸形患者的正畸治疗效果良好,有利于改善患者颌面部美观度和口腔咀嚼功能,值得临床推广应用。Objective To explore the orthodontic effect and maxillofacial aesthetics of micro-implant anchorage plus straight wire technique in the treatment of malocclusion.Methods 126 patients with malocclusion admitted to the hospital from March 2020 to March 2021 were selected as the observation subjects,and they were divided into observation group and control group by the stratified randomization method,with 63 cases in each group.The control group was given traditional straight wire orthodontic technique combined with headgear anchorage,and the observation group was treated with traditional straight wire technique combined with micro-implant anchorage.The orthodontic effect (molar displacement,incisor protrusion difference,incisor inclination angle difference,correction time) after 12 months of treatment,and hard tissue morphological indicators[sella-nasion subspinale angle (SNA),sella-nasion supramental angle (SNB),subspinale-nasion supramental angle (ANB)],periodontal indicators[gingival index (GI),dental plaque index (PLI),sulcus bleeding index (SBI),clinical attachment loss index (CAL)]and oral function (masticatory efficiency,occlusal force) before treatment and after 12 months of treatment were compared between the two groups.Results After 12 months of treatment,the molar displacement in observation group was significantly shorter than that in control group,and the incisor protrusion difference and incisor inclination angle difference were significantly greater than those in control group (P<0.05),the correction time was shorter than that of the control group (P<0.05).The SNA,ANB,GI,PLI,SBI and CAL in the two groups were significantly decreased after 12 months of treatment,and the above indicators in observation group were significantly lower than those in control group (P<0.05),and the SNB,masticatory efficiency and occlusal force in the two groups were significantly increased,and the three indicators in observation group were significantly higher than those in control group (P<0.05).Conclusion The application o
