[摘 要]目的 探究无托槽隐形矫治器在口腔正畸中的应用效果。方法 选取2020年1月-2021年12月于我院治疗的72例牙齿畸形患者为研究对象，以随机数字表法分成对照组与观察组，每组36例。对照组应用传统金属托槽矫治器，观察组应用无托槽隐形矫治器，比较两组牙周指标、PRA评分以及疗效满意度。结果 观察组菌斑指数、牙龈指数、牙龈出血指数及探诊深度低于对照组(P<0.05)；观察组前牙排列、后牙排列、覆盖、中线评分高于对照组(P<0.05)；观察组咬合关系及覆颌评分与对照组比较，差异无统计学意义(P>0.05)；观察组美观舒适度、咀嚼功能、便捷程度、语言功能、固定功能评分高于对照组(P<0.05)。结论 口腔正畸过程中应用无托槽隐形矫治器能够有效改善正畸效果，提升美观度，且患者满意度较高，值得临床应用。
