【摘要】：目的:采用Meta分析方法對自鎖托槽與傳統(tǒng)托槽尖牙遠中移動的速率進行比較并評價。方法:在Cochrane Labrary,Web of Science,MEDLINE,EMBASE、Pub Med、中國學術期刊網全文數據庫(CNKI)、萬方、Google學術等中外文數據庫檢索2017年3月之前發(fā)表的關于自鎖托槽與傳統(tǒng)托槽的尖牙遠中移動速率的隨機對照臨床研究,對納入的文獻按照《Cochrane協(xié)作網系統(tǒng)評價手冊》推薦的方法進行質量評價,應用Rev Man5.3軟件對數據進行Meta分析。結果:最終納入7篇隨機對照臨床研究。Meta分析結果顯示:自鎖托槽對比傳統(tǒng)托槽尖牙遠中移動速率沒有統(tǒng)計學意義:P=0.86,(WMD=-0.01,95%CI=[-0.18,0.16]),被動自鎖托槽相較于傳統(tǒng)托槽尖牙遠中移動速率沒有統(tǒng)計學差異:P=0.94,(WMD=0.05,95%CI=[-0.22,0.31]),主動自鎖托槽對比傳統(tǒng)托槽尖牙遠中移動速率也沒有統(tǒng)計學意義:P=0.12,(WMD=-0.11,95%CI=[-0.24,0.03])。結論:正畸矯治中,目前暫無足夠的證據證明自鎖托槽較傳統(tǒng)托槽能加快尖牙遠中移動的速率。且無論是主動自鎖或是被動自鎖托槽,相較于傳統(tǒng)托槽尖牙遠中移動的速率也都沒有統(tǒng)計學差異。
[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 鹵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.
