[摘 要]目的 探究对安氏Ⅱ类错牙合畸形伴轻中度拥挤患者采用微种植体支抗辅助上颌磨牙整体远移矫治的效果。方法 选取2020年1月-2021年12月汉滨明丽口腔诊所收治的86例安氏Ⅱ类错牙合畸形伴轻中度拥挤患者为研究对象，随机分为对照组和观察组，各43例。对照组实施上颌磨牙整体远移矫治，观察组实施微种植体支抗辅助上颌磨牙整体远移矫治，比较两组矫治效果、不良反应发生情况及矫治依从性。结果 观察组矫治总有效率为95.35%，高于对照组的76.74%(P<0.05)；观察组不良反应发生率为4.65%，低于对照组的23.26%(P<0.05)；观察组矫治依从性为95.35%，高于对照组的70.09%(P<0.05)。结论 种植体支抗辅助上颌磨牙整体远移矫治安氏Ⅱ类错牙合畸形伴轻中度拥挤的效果良好，能够抵抗磨牙远移过程中产生的反作用力，实现磨牙的整体远移，并能够维持良好的咬合关系，有利于提高患者的矫治依从性减少不良反应发生，值得临床应用。
