【摘要】：目的:采用Meta分析方法对自锁托槽与传统托槽尖牙远中移动的速率进行比较并评价。方法:在Cochrane Labrary,Web of Science,MEDLINE,EMBASE、Pub Med、中国学术期刊网全文数据库(CNKI)、万方、Google学术等中外文数据库检索2017年3月之前发表的关于自锁托槽与传统托槽的尖牙远中移动速率的随机对照临床研究,对纳入的文献按照《Cochrane协作网系统评价手册》推荐的方法进行质量评价,应用Rev Man5.3软件对数据进行Meta分析。结果:最终纳入7篇随机对照临床研究。Meta分析结果显示:自锁托槽对比传统托槽尖牙远中移动速率没有统计学意义:P=0.86,(WMD=-0.01,95%CI=[-0.18,0.16]),被动自锁托槽相较于传统托槽尖牙远中移动速率没有统计学差异:P=0.94,(WMD=0.05,95%CI=[-0.22,0.31]),主动自锁托槽对比传统托槽尖牙远中移动速率也没有统计学意义:P=0.12,(WMD=-0.11,95%CI=[-0.24,0.03])。结论:正畸矫治中,目前暂无足够的证据证明自锁托槽较传统托槽能加快尖牙远中移动的速率。且无论是主动自锁或是被动自锁托槽,相较于传统托槽尖牙远中移动的速率也都没有统计学差异。
[Abstract]:Objective: to compare and evaluate the rate of distal movement between self-locking brackets and traditional brackets by Meta analysis. Methods: (CNKI), Wanfang, a full-text database of Cochrane Labrary,Web of Science,MEDLINE,EMBASE,Pub Med, China academic Journals Network, was used. Google academic and other Chinese and foreign language databases to retrieve a randomized controlled clinical study on the rate of distal canine movement between self-locking brackets and traditional brackets published before March 2017. According to the method recommended in the Manual of Evaluation of Cochrane Cooperative Network system, the quality of the included documents is evaluated, and the Meta analysis of the data is carried out by using Rev Man5.3 software. Results: seven randomized controlled clinical studies were included. The results of Meta analysis showed that there was no significant difference in the rate of movement of self-locking brackets in the distal distance of canine teeth compared with the traditional ones: P < 0.86 (WMD=-0.01,95%CI= [-0.180.16]). There was no significant difference in the rate of distal movement between passive and self-locking brackets compared with the traditional ones: Pao 0.94 (WMD=0.05,95%CI= [-0.22 卤0.31]). There was also no significant difference in the rate of movement of active self-locking brackets in far canine teeth compared with the traditional ones: Pao 0.12 (WMD=-0.11,95%CI= [-0.24] 0.03]). Conclusion: in orthodontic treatment, there is not enough evidence to prove that self-locking brackets can accelerate the rate of distal canine movement. There was no statistical difference in the rate of distal movement between active and passive self-locking brackets compared with traditional brackets.
