    [摘要]目的：探討固定矫治联合微种植体支抗治疗青少年安氏Ⅱ类错牙合畸形患者的疗效。方法：将2019年1月-2021年12月笔者医院收治的85例安氏Ⅱ类错牙合畸形患者纳入研究。根据是否配合使用微种植体支抗分为对照组(n=42)和观察组(n=43)。对照组患者采用固定矫治器治疗，观察组患者采用固定矫治联合微种植体支抗治疗。随访1年，比较两组SNA角、SNB角、GO-GN-SN角、OP-SN角等颌面部指标，比较两组前牙覆牙合覆盖、磨牙咬合关系、中线关系等错牙合畸形指标。治疗后，两组生活质量采用SF-36生活质量量表评估比较，采用医院自制外观功能满意度对两组矫治满意度进行评估比较。结果：治疗后，两组SNA值略有下降，SNB值、GO-GN-SN值、OP-SN值略有增加，且观察组SNA值低于对照组，SNB值、GO-GN-SN值、OP-SN值均高于对照组(P<0.05)；治疗后，两组前牙覆盖、前牙覆牙合、磨牙咬合关系、中线关系评分均低于治疗前，且观察组低于对照组(P<0.05)；治疗后，观察组心理功能、运动功能、饮食功能及生理功能等生活质量评分均高于对照组(P<0.05)；治疗后，观察组外形、舒适度、咬合功能和便捷性等满意度评分均高于对照组(P<0.05)。结论：青少年安氏Ⅱ类错牙合畸形患者应用固定矫治器联合微种植体支抗治疗效果显著，可有效改善患者颌面部组织形态，降低错牙合畸形严重程度，提高患者生活质量，患者满意度更高。

    Abstract： Objective? To investigate the effect of fixed orthodontics combined with micro-implant anchorage in the treatment of Class Ⅱ malocclusion in adolescents. Methods? Eighty-five patients with Class Ⅱ malocclusion treated in the author's hospital from January 2019 to December 2021 were included in the study. They were divided into control group (n=42) and observation group (n=43) according to whether the anchorage nail was used together for planting. The patients in the control group were treated with fixed orthodontic treatment ......
