[摘要]目的：探讨骨皮质切开术联合口腔正畸治疗骨性Ⅱ类错牙合畸形的效果及对软组织侧貌变化的影响。方法：选取2019年3月-2024年3月笔者医院收治的100例骨性Ⅱ类错牙合畸形患者为研究对象，随机分为两组。对照组：50例，采用常规口腔正畸治疗；观察组：50例，行骨皮质切开术联合口腔正畸治疗，对两组患者治疗效果、软组织侧貌变化进行比较。结果：观察组牙排齐时间、间隙关闭时间、完成矫治时间均较对照组短(P<0.05)；观察组加力1、2、3个月的U1I-CP距减少量均较对照组高(P<0.05)；治疗后，观察组鼻唇角、上唇倾角、下唇倾角、颏沟倾角、上唇突度、下唇突度、上唇长、下唇长与对照组比较差异明显，均有统计学意义(P<0.05)。结论：骨皮质切开术联合口腔正畸治疗不仅能缩短骨性Ⅱ类错牙合畸形的治疗周期，还能提升治疗效果，尤其可有效改善患者软组织侧貌，值得临床应用推广。
