摘　　要：目的:观察自锁托槽矫治器在错[牙合]畸形患儿正畸治疗中的应用效果。方法:回顾性分析2016年7月至2019年7月在该院行正畸治疗的90例错[牙合]畸形患儿的临床资料,按照矫治器的不同分为观察组(n=45)和对照组(n=45)。观察组采用自锁托槽矫治器正畸治疗,对照组采用传统金属托槽正畸治疗。比较两组治疗前后牙周指数(菌斑指数、牙龈指数和龈沟出血指数)、龈沟液炎性指标[白细胞介素-1β(IL-1β)、IL-6和肿瘤坏死因子α(TNF-α)]水平和托槽脱落率。结果:治疗后,观察组菌斑指数、牙龈指数和龈沟出血指数均低于对照组,差异有统计学意义(P<0.05);治疗后1年,观察组托槽脱落率为2.22%(1/45),低于对照组的17.78%(8/45),差异有统计学意义(P<0.05);治疗后,观察组龈沟液IL-1β、IL-6和TNF-α水平均低于对照组,差异有统计学意义(P<0.05)。结论:自锁托槽矫治器正畸治疗错[牙合]畸形患儿,可改善其牙周指数、降低托槽脱落率和龈沟液炎性指标水平,效果优于传统金属托槽正畸治疗。Objective:To observe application effects of self-locking bracket appliance in orthodontic treatment of patients with malocclusion.Methods:90 malocclusion patients who underwent orthodontic treatment were selected as the research objects,and were divided into observation group(n=45)and control group(n=45)according to the patients’wishes.The observation group was given orthodontic treatment with self-locking appliance,while the control group was given traditional metal brackets.The periodontal index levels(plaque index,gingival index and gingival crevicular bleeding index),the gingival crevicular fluid inflammatory index levels[interleukin-1β(IL-1β),IL-6 and tumor necrosis factorα(TNF-α)]and the bracket losing rate were compared between the two groups before and after the treatment.Results:After the treatment,the plaque index,the gingival index and the gingival sulcus bleeding index in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).One year after the treatment,the bracket losing rate in the observation group was 2.22%(1/45),which was lower than 17.78%(8/45)in the control group,and the difference was statistically significant(P<0.05).Further,after the treatment,the levels of IL-1β,IL-6 and TNF-αin the gingival crevicular fluid of the observation group were lower than those of the control group,and the differences were statistically significant(P<0.05).Conclusions:The orthodontic treatment of the patients with malocclusion with self-locking bracket appliance can improve the periodontal index and reduce the bracket losing rate and the gingival crevicular fluid inflammatory index levels.Moreover,it is superior to traditional metal bracket orthodontic treatment.
