摘　　要：目的分析比较微型种植体支抗与口外弓加强支抗正畸法对错[牙合]畸形患者的影响。方法回顾性分析2021年1月至2024年1月南华大学附属南华医院收治的86例错[牙合]畸形患者病历信息,按照治疗方式不同分为两组,均43例。对照组行口外弓加强支抗正畸法,观察组行微型种植体支抗。对比两组矫正效果。结果观察组正畸成功率为95.35%(41/43),高于对照组的81.40%(35/43),并发症发生率为4.65%(2/43),低于对照组的18.60%(8/43);且矫正后的磨牙移位为(3.25±0.42)mm,小于对照组的(5.41±0.96)mm,上中切牙倾角为(25.97±3.48)°、上中切牙凸距差为(4.37±0.89)mm,咬合力为(142.59±9.26)Ibs、咀嚼效率为(79.63±7.05)%,红色美学指数(PES)评分为(10.11±1.59)分,高于对照组的(13.46±2.39)°、(2.40±0.56)mm、(115.68±7.69)Ibs、(70.69±5.88)%、(8.71±1.63)分,差异均有统计学意义(P<0.05)。结论微型种植体支抗更能够改善错[牙合]畸形患者口腔结构,改善咀嚼功能,提高美观度,并发症较少。Objective To analyze and compare the effects of mini implant anchorage and intraoral arch reinforcement anchorage orthodontic methods on patients with malocclusion.Methods A retrospective analysis was conducted on the medical records of 86 patients with malocclusion admitted to Nanhua Hospital affiliated with Nanhua University from January 2021 to January 2024.They were divided into two groups according to different treatment methods,with 43 cases in each group.The control group underwent external arch strengthening orthodontic treatment,while the observation group underwent micro implant support.Compare the corrective effects of two groups.Results The orthodontic success rate in the observation group was 95.35%(41/43),which was higher than the 81.40%(35/43)in the control group.The complication rate was 4.65%(2/43),which was lower than the 18.60%(8/43)in the control group;After correction,the molar displacement was(3.25±0.42)mm,which was smaller than the control group's(5.41±0.96)mm.The inclination angle of the upper central incisor was(25.97±3.48)°,the difference in convexity of the upper central incisor was(4.37±0.89)mm,the bite force was(142.59±9.26)Ibs,the chewing efficiency was(79.63±7.05)%,and the red aesthetic index(PES)score was(10.11±1.59)points,which was higher than the control group's(13.46±2.39)°,(2.40±0.56)mm,(115.68±7.69)Ibs,(70.69±5.88)%,and(8.71)%.±1.63)points,the differences were statistically significant(P<0.05).Conclusions Micro implant anchorage is more effective in improving oral structure,enhancing chewing function,improving aesthetics,and reducing complications in patients with malocclusion.
