摘　　要：目的对比口腔正畸治疗中采用微型种植支抗与口外弓加强支抗的临床效果。方法回顾性分析2018年1月-2022年12月在泰兴市人民医院进行口腔正畸治疗的患者92例,随机分为两组,对照组46例,采用口外弓加强支抗治疗;观察组46例,采用微型种植支抗治疗。比较两组治疗效果、临床指标、咬合力与咀嚼效率、不良反应。结果观察组治疗总有效率高于对照组,差异有统计学意义(P<0.05)。治疗后,观察组上、下牙槽座角、下中切牙倾角、上中切牙凸距差、尖牙间宽度与磨牙移位值均优于对照组,咬合力与咀嚼效率均高于对照组,差异有统计学意义(P<0.05)。观察组不良反应总发生率较对照组更低,差异有统计学意义(P<0.05)。结论在口腔正畸治疗中应用微型种植支抗的效果较口外弓加强支抗更好,患者咀嚼功能改善更为明显,且不良反应更少。Objective:To compare the clinical effects of micro-implant anchorage and extraoral arch anchorage in orthodontic treatment.Methods:A retrospective analysis was made on 92 patients who underwent orthodontic treatment in Taixing People's Hospital from January 2018 to December 2022.They were randomly divided into two groups,the control group(46 cases)and the control group(46 cases).46 cases in the observation group were treated with micro-implant anchorage.The therapeutic effect,clinical indicators,bite force and masticatory efficiency,and adverse reactions were compared between the two groups.Results:The total effective rate in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05).After treatment,the angle of the upper and lower alveolar seats,the inclination angle of the lower central incisors,the difference of the convex distance of the upper central incisors,the width between the canines and the molar displacement in the observation group were all better than those in the control group,and the bite force and chewing efficiency were higher than those in the control group,with statistical significance(P<0.05).The total incidence of adverse reactions in observation group was lower than that in control group,and the difference was statistically significant(P<0.05).Conclusion:The effect of mini-implant anchorage in orthodontic treatment is better than that of strengthening anchorage with extraoral arch,and the masticatory function of patients is improved more obviously with less adverse reactions.
