[摘 要]目的 探讨正畸治疗后牙面白斑样病损患者采用渗透树脂结合微研磨技术进行修复的美学效果。方法 选择2019年1月-2022年2月西宁市口腔医院收治的60例正畸后牙面白斑样病损患者作为研究对象，随机分为常规组和试验组，各30例。常规组单纯应用微研磨技术进行治疗，试验组在常规组基础上应用渗透树脂技术进行治疗，比较两组修复效果、病损情况、患牙色度与硬度。结果 试验组修复总有效率高于常规组(P<0.05)；试验组治疗后病损面积比低于常规组，白斑样病损软件与主观评分均高于常规组(P<0.05)；试验组治疗后SMH高于常规组，L*值低于常规组(P<0.05)。结论 正畸治疗后牙面白斑样病损患者采用渗透树脂进行修复效果理想，可减少病损面积，改善病损情况及患牙色度与硬度，值得临床应用。
