【摘要】：目的:研究隐形矫治器、自锁托槽及传统托槽对成人正畸患者牙周指数及龈沟液内炎性因子水平的影响。方法:90例成人正畸患者随机分为传统组、自锁组及隐形组(n=30),分别佩戴传统MBT托槽、Damon Q自锁托槽及Invisalign隐形矫治器,观察矫治前、矫治后1、3、6个月及矫治结束时患者菌斑指数(PLI)、探诊深度(PD)及龈沟液内白介素1β(IL-1β)、肿瘤坏死因子α(TNF-α)的变化情况。结果:矫治后1~6个月,传统组及自锁组患者牙周指数及龈沟液内炎性因子水平持续升高(P0.05),6个月达最高峰,矫治后1个月自锁组与传统组比较无显著差异(P0.05),矫治后3个月至矫治结束自锁组牙周指数及炎性因子水平均明显低于传统组(P0.05)。隐形组患者PLI、IL-1β及TNF-α在矫治后6个月较矫治前升高(P0.05),但矫治后各项指标均显著低于传统组及自锁组(P0.05)。结论:自锁托槽在正畸矫治中后期对牙周组织的影响小于传统托槽,隐形矫治器及自锁托槽与传统托槽相比,在正畸矫治后各个时期均更利于牙周组织的健康。
[Abstract]:Objective: to study the effects of invisible appliance, self-locking bracket and traditional bracket on periodontal index and inflammatory factors in gingival crevicular fluid in adult orthodontic patients. Methods: 90 adult orthodontic patients were randomly divided into traditional group. The self-locking group and the invisible group were respectively wearing the traditional MBT bracket and Invisalign self-locking bracket before the treatment. The changes of plaque index (PLII), probing depth (PDD), interleukin-1 尾 (IL-1 尾) and tumor necrosis factor 伪 (TNF- 伪) in gingival crevicular fluid were observed 1, 6 months after treatment and at the end of treatment. Results: 1 ~ 6 months after treatment, there were significant differences in the changes of plaque index, depth of diagnosis, and tumor necrosis factor 伪 (TNF- 伪) in gingival crevicular fluid. The periodontal index and the level of inflammatory factors in gingival crevicular fluid of patients in traditional group and self-locking group were increased continuously and reached the peak at 6 months. There was no significant difference between the self-locking group and the traditional group one month after treatment. The periodontal index and inflammatory factor levels in the self-locking group from 3 months after treatment to the end of the correction group were significantly lower than those in the traditional group. The levels of PLII-IL-1 尾 and TNF- 伪 in the invisible group were significantly lower than those in the traditional group 6 months after treatment. Compared with that before orthodontic treatment, all the indexes were significantly lower than those in the traditional group and the self-locking group. Conclusion: the effect of self-locking bracket on periodontal tissue in the middle and late period of orthodontic treatment is less than that in the traditional bracket, and the effect of self-locking bracket on periodontal tissue in the middle and late period of orthodontic treatment is lower than that in the control group. Compared with traditional brackets, invisible orthodontics and self-locking brackets are more beneficial to the health of periodontal tissue in each period after orthodontic treatment.
