[摘要] 目的 分析和探讨固定矫治与无托槽矫治治疗牙周病致前牙移位的疗效。 方法 选取2012年3月至2019年3月在我院治疗的牙周病致前牙移位患者30例为研究对象，随机分为对照组和观察组，每组各15例。对照组采用固定矫治治疗，观察组采用无托槽矫治治疗，比较两组美观度、便捷性、語言功能及咀嚼功能评分、牙周指数、前牙覆盖距离、前牙覆■深度。 结果 治疗后观察组美观度、便捷性、语言功能及咀嚼功能评分均高于对照组，差异有统计学意义（P<0.05）;治疗后观察组PLI、GI、SBI均低于对照组，差异有统计学意义（P<0.05）;矫治治疗后6个月、矫治结束时及保持3个月时，观察组前牙覆盖距离均低于对照组，差异有统计学意义（P<0.05）;矫治治疗后1个月、6个月、矫治结束时及保持3个月时，观察组前牙覆■深度均低于对照组，差异有统计学意义（P<0.05）。 结论 无托槽矫治治疗牙周病致前牙移位的疗效更佳，值得推广。

[Abstract] Objective To analyze and discuss the effect of fixed appliance and bracketless appliance in the treatment of front teeth shifting induced by periodontal disease. Methods Thirty patients with front teeth shifting induced by periodontal disease in our hospital from March 2012 to March 2019 were randomly collected as the study object. They were random divided into the control group and the observation group， with 15 cases in each group. The control group was treated with fixed appliance， and the observation group was treated with bracketless appliance. The aesthetic， convenience， language function and chewing function scores， periodontal index， anterior overbite distance and depth of anterior overbite between the two groups were compared. Results The aesthetic， convenience， language function and chewing function scores of the observation group were all higher than those of the observation group， the differences were statistically significant（P<0.05）. The PLI， GI， and SBI of the observation group were all lower than those of the control group， the differences were statistically significant（P<0.05）. The anterior tooth coverage distance of the observation group was lower than that of the control group at 6 months after the appliance treatment， at the end of the treatment， and when held for 3 months， and the differences were statistically significant （P<0.05）. The depth of anterior overbite of the observation group were significantly lower than that of the control group at 1 month， 6 months after treatment， at the end of treatment， and 3 months after maintenance（P<0.05）. Conclusion Bracketless appliance is more effective in treating front teeth shifting induced by periodontal disease and is worthy of promotion.

牙周病致前牙移位是临床上常见的口腔疾病，往往需要进行口腔正畸治疗[1]，随着医学的不断发展，口腔学也取得了巨大进步和成就。随着人们对于美观度的追求越来越高，人们对于口腔正畸治疗的要求和需求也越来越高。目前临床主流的正畸治疗涵盖固定矫治器治疗和无托槽隐形矫治器治疗[2]，这两种治疗方式在临床上均有广泛的使用，且受到医生和患者的广泛欢迎。本研究以临床患者作为研究对象，对固定矫治与无托槽矫治治疗牙周病致前牙移位的疗效进行深入分析，现报道如下。
