文题释义:
自锁托槽:是临床正畸固定矫治器的一种,用自身闭锁结取代不锈钢结扎丝和弹性结扎圈来固定弓丝。主要优点是可以显著降低钢丝与托槽之间的摩擦阻力。因为它在托槽上加了一道门,可以直接将正畸钢丝锁闭在托槽的槽沟内,免除了结扎钢丝或橡皮圈对正畸钢丝的捆绑。
矫治效率:即正畸矫正治疗的效率,涵盖内容主要包括5个方面:矫治时间、复诊次数、整平排齐时间、拔牙间隙闭合时间、椅旁操作时间。
 
 
背景:临床正畸治疗中托槽类型的选择与矫治效率密切相关。自锁托槽标榜以低摩擦力、操作简单、患者疼痛不适感轻等优势,成为口腔正畸临床应用和研究热点。近年来,不同的研究类型对自锁托槽比较传统结扎丝托槽矫治效率进行了相关报道,但其研究结果各不相同。
目的:系统评价自锁托槽对比传统结扎丝托槽的矫治效率。
方法:应用计算机以“orthodontic brackets/self ligating,random”和“矫治器/自锁/传统/矫治效率,随机/随机对照试验”为中英文检索词,分别检索PubMed、EMBASE、MEDLINE、万方、维普、中国知网数据库,收集关于自锁托槽比较传统结扎丝托槽矫治效率的随机对照试验,检索时限均为建库至2017年12月。研究者完成文献筛选、资料提取和偏倚风险的评价后,采用Stata 12.0软件进行Meta分析。

结果与结论:①共纳入9篇随机对照试验,共603例患者;②Meta分析显示,自锁托槽与传统结扎丝托槽在矫治时间、复诊次数、整平排齐时间、拔牙间隙闭合时间比较,差异无显著性意义(P > 0.05)。与仅传统结扎丝托槽相比,自锁托槽显著缩短椅旁操作时间(P < 0.05);③结果说明,自锁托槽对比传统结扎丝托槽矫治效率无明显优势。

Abstract:

BACKGROUND: The type of brackets is closely related to the efficiency of orthodontic treatment. A self-ligating bracket is characterized by low friction, simple operation, mild pain and discomfort, and it has been an issue of concern in orthodontics. In recent years, studies on the therapeutic efficiency of self-ligating brackets versus conventional brackets for orthodontic correction have been reported, but there is no conclusion.

OBJECTIVE: To systematically compare the conventional and self-ligating brackets concerning treatment efficiency.
METHODS: A computer-based search of PubMed, EMBASE, MEDLINE, WanFang, VIP and CNKI was performed for randomized controlled trials concerning self-ligating brackets versus conventional brackets for orthodontic correction. The keywords were “orthodontic brackets/ self-ligating, random” in English and “appliance/self-ligating/ conventional/orthodontic correction efficiency” in Chinese. The retrieve time was set from inception to December 2017. Stata12.0 software was used for meta-analysis following literature screening, data extraction and risk assessment of bias.

RESULTS AND CONCLUSION: A total of 9 randomized controlled trials involving 603 patients were included. The results of meta-analysis on the efficiency of the two groups showed that there was no significant difference in overall treatment time, number of visits, time of alignment and time of space closure (P > 0.05). Only the time of chairside operation showed significant difference between the two groups (P < 0.05). These findings indicate that compared with the conventional bracket, the self-ligating bracket has no obvious advantage in the therapeutic efficiency.
