Comparison on the Efficacy of Self-Locking Bracket Fixed Appliance and Ordinary Metal Straight Wire Appliance in Orthodontic Treatment for Patients with Periodontitis

目的比较自锁托槽固定矫正器与普通金属直丝弓矫正器在牙周炎患者正畸治疗中的疗效。方法选取我院2016年9月至2018年8月收治的牙周炎患者40例,随机分为两组各20例。对照组使用普通金属直丝弓矫正器行正畸治疗,观察组使用自锁托槽固定矫正器行正畸治疗。比较两组的牙周情况以及血清炎性因子水平。结果治疗12个月后,观察组的PLI、SBI、牙周袋探诊深度以及IL-1β、IL-8、TNF-α水平均显著低于对照组(P<0.05)。结论牙周炎患者使用自锁托槽固定矫正器进行正畸治疗,能够有效恢复牙齿美观与功能属性,保障牙周基础治疗效果,可在促进疗效基础上缩短疗程。

Objective To compare the efficacy of self-locking bracket fixed appliance and ordinary metal straight wire appliance in orthodontic treatment for patients with periodontitis.
