[摘 要]目的 探讨采用隐形矫治器治疗青少年骨性Ⅱ类错颌畸形的效果。方法 选择2020年3月-2022年4月我院收治的68例青少年骨性Ⅱ类错颌畸形患者为研究对象，采用随机数字表法分为常规组和试验组，各34例。常规组应用传统正畸治疗，试验组应用隐形矫治器治疗，比较两组颞下颌关节指标、咬合功能及颞下颌关节间隙指标、满意度。结果 试验组治疗后髁突短轴长度、髁突上部高度高于常规组(P<0.05)；两组治疗后关节结节倾斜角、关节窝深度、踝突长轴长度、踝突-正中面距比较，差异无统计学意义(P>0.05)；两组R值、颞下颌关节前间隙、颞下颌关节后间隙、颞下颌关节上间隙比较，差异无统计学意义(P>0.05)；试验组满意度为97.06%，高于常规组的79.41%(P<0.05)。结论 采用隐形矫治器治疗青少年骨性Ⅱ类错颌畸形效果较好，能够有效提升髁突短轴长度、髁突上部高度，有利于促进颌骨正常发育以及咬合功能的恢复，且患者满意度较高，值得临床应用。
