[摘要]目的：探讨微种植体支抗在矫治成人双颌前突中的临床应用效果。方法：选取2020年1月-2022年12月北京怀柔医院口腔科就诊的78例成人双颌前突患者，参照随机数字表法分为对照组（n=39）和研究组（n=39）。两组均使用直丝弓托槽进行矫正，对照组采用传统方式支抗正畸治疗，研究组采用微种植体支抗正畸治疗，统计比较两组矫治各个阶段时间、硬组织[下中切牙唇倾角（L1-MP）、蝶鞍中心、鼻根点及上牙槽座点交角（SNA）、上中切牙唇倾角（UI-SN）、上下中切牙长轴交角（UI-L1）]变化、软组织[下唇至审美平面垂直距离（L1-E1）、上唇最低点与中切牙最高点距离（GSL）、上唇至审美平面的垂直距离（UI-E1）]变化及外观功能满意度。结果：研究组关闭拔牙间隙时间、精细调整与被动保持时间较对照组短（P＜0.05）；治疗后，研究组L1-MP、U1/PP及L1-E1、UI-E1、GSL水平较对照组低，UI-L1水平较对照组高（均P＜0.05）；研究组整体外形、舒适度、前牙内收程度、咬合功能满意度较对照组高（P＜0.05）。结论：微种植体支抗矫治成人双颌前突效果优良，可缩短矫治时间，改善患者软硬组织侧貌，提高患者外观功能满意度。

Abstract： Objective" Exploring the application effect of orthodontic treatment for adult bimaxillary protrusion combined with micro implant nails. Methods" 78 adult patients with bimaxillary protrusion in the hospital from January 2020 to December 2022 were selected and randomly divided into a control group （n=39） and a study group （n=39） according to the random number table method. The control group was treated with traditional orthodontic anchorage， and the study group was treated with micro screw implant anchorage. The time of each stage of orthodontic treatment， the changes of hard tissue [lower central incisor lip angle （L1-MP）， the center of sphenoid amine， the nasal root point and the intersection angle of the upper alveolar seating point （SNA）， the upper central incisor lip angle （UI-SN）， and the intersection angle of the long axis of the upper and lower central incisors （UI-L1）] were statistically compared between the two groups Changes in soft tissue [vertical distance from lower lip to aesthetic plane （L1-E1）， distance from the lowest point of upper lip to the highest point of central incisor （GSL）， vertical distance from upper lip to aesthetic plane （UI-E1）]， and satisfaction with appearance and function. Results" The closing time， fine adjustment， and passive retention time of the study group were shorter than those of the control group （P＜0.05）; After treatment， the levels of L1-MP， U1/PP， L1-E1， UI-E1， and GSL in the study group were lower than those in the control group， while the levels of UI-L1 were higher than those in the control group （ all P＜0.05）. The overall appearance， comfort， anterior tooth adduction， and satisfaction with occlusal function of the study group were higher than those of the control group （P＜0.05）. Conclusion" The combination of micro implant nail in orthodontic treatment of adult bimaxillary protrusion has a significant effect， which can shorten the treatment time， improve the profile of soft and hard tissues of patients， improve the satisfaction of patients with appearance and function.

双颌前突是临床常见面部畸形，成人为高发人群，表现为颏部后缩、面下1/3向前突出等，严重影响患者颜面部美观[1-3]。目前，临床治疗成人双颌前突主要以矫治为主，以促进上下颌前牙与牙槽突尽可能内收，从而改善患者面貌，使其趋于正常化[3-4]。成人双……
