摘　　要：目的探讨上颌前突患者应用微型种植体支抗治疗的临床效果。方法随机选取2021年1月—2023年12月福建省龙岩市第二医院口腔科收治的110例上颌前突患者为研究对象,依据不同治疗方法分为对照组及观察组,各55例。对照组使用传统口外弓支抗治疗,观察组使用微型种植体支抗治疗,对比两组牙周状况改变情况、咀嚼功能改变情况、矫治效果、并发症发生情况。结果治疗后,观察组附着丧失(3.20±0.22)mm、牙龈指数(1.03±0.14)分、菌斑指数(1.13±0.19)分、龈沟出血指数(0.78±0.16)分均低于对照组的(3.71±0.44)mm、(1.31±0.20)分、(1.42±0.23)分、(0.95±0.19)分,差异均有统计学意义(t=7.689,8.506,7.209,5.076;P均<0.05)。治疗后,两组咀嚼功能优于治疗前,观察组优于对照组,差异均有统计学意义(P均<0.05)。观察组上颌中切牙中心点至Y轴距离减少值、上颌第一磨牙中心点至Y轴距离减少值、上唇突距减少值、鼻唇角增加值均高于对照组,差异均有统计学意义(P均<0.05)。并发症总发生率观察组比对照组低,差异有统计学意义(P<0.05)。结论应用微型种植体支抗治疗上颌前突患者的矫治效果较好,对牙周状况产生的影响更小,有助于提高患者咀嚼功能,该方法的并发症发生率更低。Objective To investigate the clinical effect of micro-implant anchorage in patients with maxillary protrusion.Methods A total of 110 patients with maxillary protrusion admitted to the Department of Stomatology,the Second Hospital of Longyan City,Fujian Province from January 2021 to December 2023 were randomly selected as the research objects.According to different treatment methods,they were divided into control group and observation group,with 55 cases in each group.The control group was treated with traditional extraoral arch anchorage,and the observation group was treated with micro-implant anchorage.The changes of periodontal status,changes of chewing function,correction effect and complications were compared between the two groups.Results After treatment,the attachment loss(3.20±0.22)mm,gingival index(1.03±0.14)points,plaque index(1.13±0.19)points,and gingival sulcus bleeding index(0.78±0.16)points in the observation group were lower than those in the control group(3.71±0.44)mm,(1.31±0.20)points,(1.42±0.23)points,(0.95±0.19)points,and the differences were statistically significant(t=7.689,8.506,7.209,5.076;all P<0.05).After treatment,the chewing function of the two groups was better than that before treatment,and the observation group was better than the control group,the differences were statistically significant(both P<0.05).The reduction value of the distance from the center point of the maxillary central incisor to the Y axis,the reduction value of the distance from the center point of the maxillary first molar to the Y axis,the reduction value of the upper lip protrusion distance,and the increase value of the nasolabial angle in the observation group were higher than those in the control group,and the differences were statistically significant(all P<0.05).The total incidence of complications in the observation group was lower than that in the control group,the difference was statistically significant(P<0.05).Conclusion The application of micro-implant anchorage in the treatment of patients with
