摘　　要：目的 探讨微型种植支抗与口外弓加强支抗在口腔正畸治疗中的效果。方法 随机选取2020年5月-2021年5月于福建省南平市第二医院行口腔正畸治疗的患者100例为研究对象,采用双盲法分为观察组和对照组。观察组(50例)予以微型种植支抗治疗,对照组(50例)采取口外弓加强支抗治疗。比较两组患者的口腔正畸治疗效果。结果 观察组上牙槽座角、下牙槽座角、上中切牙凸距差、下中切牙倾角及尖牙间宽度均较对照组更优,磨牙移位距离较对照组短,差异有统计学意义(P<0.05);观察组不良反应发生率为8.00%,低于对照组的26.00%,差异有统计学意义(χ^(2)=5.740,P<0.05);观察组治疗总有效率为96.00%,高于对照组的80.00%,差异有统计学意义(χ^(2)=6.060,P<0.05);观察组出血指数、菌斑指数及牙龈指数均低于对照组,差异有统计学意义(P<0.05)。结论 对比微型种植支抗与口外弓加强支抗在口腔正畸治疗中的整体疗效,前者的治疗有效率、矫正效果明显优于后者,且还能改善患者牙龈状况,减少创伤,不良反应较少,有较高安全性,值得借鉴。Objective To explore the effect of micro-implant bracing versus extra-oral arch strengthening bracing in orthodontic treatment.Methods 100 patients who underwent orthodontic treatment in the Second Hospital of Nanping City,Fujian Province from May 2020 to May 2021 were randomly selected as the study subjects.They were divided into observation group and control group by double-blind method,the observation group(50 cases)was treated with micro-implant anchorage,and the control group(50 cases)was treated with extraoral arch reinforcement anchorage.The orthodontic treatment effects of the two groups were compared.Results The upper alveolar seating angle,lower alveolar seating angle,upper central incisor projection difference,lower central incisor inclination angle and intercanine width of the observation group were better than those of the control group,and the molar displacement distance was shorter than that of the control group,the difference was statistically significant(P<0.05).The incidence of adverse reactions was 8.00%in the observation group,which was lower than that of 26.00%in the control group,the difference was statistically significant(χ^(2)=5.740,P<0.05).The total treatment efficiency was 96.00%in the observation group,which was higher than that of 80.00%in the control group,the difference was statistically significant(χ^(2)=6.060,P<0.05).The bleeding index,plaque index and gingival index in the observation group were lower than those in the control group,the difference was statistically significant(P<0.05).Conclusion Comparing the overall efficacy of microimplant brace and extra-oral arch strengthening brace in orthodontic treatment,the former has significantly better treatment efficiency and orthodontic effect than the latter,and also improves the gingival condition of patients,reduces trauma,has less adverse reactions and has higher safety,which is worthy of reference.
