无托槽隐形矫治技术与传统固定矫治技术对患者牙周健康影响的对比研究

A comparative study on periodontal health of patients with invisible orthodontic technology without bracket and traditional fixed orthodontic technology

目的探究无托槽隐形矫治技术与传统固定矫治技术对患者牙周健康影响。方法选取2017年5月至2020年2月于本院正畸科接受正畸治疗的100例患者作为研究对象,随机分为常规组(传统固定矫治技术)与研究组(无托槽隐性矫治技术),每组50例。比较两组临床疗效、牙周健康指标、VAS评分及不良反应发生率。结果两组PAR指数比较差异无统计学意义。矫治前,两组牙周指数、菌斑指数、牙龈指数比较差异无统计学意义;矫治6个月后,研究组牙周指数、菌斑指数、牙龈指数均低于常规组,差异有统计学意义(P<0.05)。矫治2、4、6个月,研究组VAS评分均低于常规组,差异有统计学意义(P<0.05)。研究组不良反应发生率为10.00%,明显低于常规组的24.00%(P<0.05)。结论与传统固定矫治技术相比,无托槽隐性矫治技术具有更高的安全性、舒适性与美观性,且有利于维护患者口腔卫生与牙周健康,效果显著。

Objective To investigate the effects of invisible orthodontic techniques without brackets and traditional fixed orthodontic techniques on periodontal health of patients.Methods 100 patients who received orthodontic treatment in the orthodontic Department of our hospital from May2017 to February 2020 were selected as the research subject and they were randomly divided into the conventional group(traditional fixed orthodontic technique)and the study group(recessive orthodontic technique without bracket),with 50 cases in each group.The clinical efficacy,periodontal health index,VAS score and incidence of adverse reactions between the two groups were compared.Results There was no significant difference in PAR index between the two groups.Before treatment,there was no significant difference in periodontal index,plaque index and gingival index between the two groups.After 6 months of treatment,the periodontal index,plaque index and gingival index of the study group were lower than those of the conventional group,the difference was statistically significant(P<0.05).After 2,4 and 6 months of treatment,VAS score of the study group was lower than that of the conventional group,the difference was statistically significant(P<0.05).The incidence of adverse reactions in the study group was 10.00%,which was significantly lower than 24.00%in the conventional group(P<0.05).Conclusion Compared with traditional fixed orthodontic technique,recessive orthodontic technique without bracket has higher safety,comfort and aesthetics,and is beneficial to the maintenance of oral health and periodontal health of patients.
