自锁托槽矫正器对正畸患者牙周健康影响的临床研究

Effects of self-locking orthodontic bracket on the periodontal health of orthodontic patients

目的探讨自锁托槽矫治器对正畸患者牙周健康的影响。方法研究组给予自锁托槽矫治器治疗；对照组给予传统结扎式托槽治疗。记录两组错颌畸形患者治疗前后牙周健康随访情况。结果两组患者治疗后GI、PLI、SBI评分均较治疗前有所变化，但研究组变化幅度明显低于对照组（P〈0．05）；研究组患者对治疗结果满意度显著高于对照组（P〈0．05）。结论使用自锁托槽矫治器进行正畸治疗有利于保护患者牙周组织健康，使其获得满意预后，保障患者生活质量，维持良好的医患关系。
