【摘要】：目的 比較自鎖托槽與傳統(tǒng)托槽兩者在非拔牙矯治牙列輕中度擁擠時上下頜牙弓寬度及前牙唇傾度的變化是否存在差異，為臨床應用提供依據(jù)。 方法 采用循證醫(yī)學系統(tǒng)評價方法，通過計算機檢索PubMed、EMBASE、ISI、Cochrane臨床對照試驗資料庫、萬方科技期刊全文數(shù)據(jù)庫、中國生物醫(yī)學文獻數(shù)據(jù)庫（CBM）、相關(guān)期刊論文（CNKI）、維普中文科技期刊數(shù)據(jù)庫（VIP）及輔以手工檢索等方式，全面收集比較自鎖托槽與傳統(tǒng)托槽在非拔牙矯治時上下頜牙弓寬度及前牙唇傾度變化的文獻，檢索截止日期至2013年12月31日。由兩名評價者按照納入與排除標準篩選文獻、并將納入的文獻進行質(zhì)量評價及數(shù)據(jù)資料提取，運用Cochrane協(xié)作網(wǎng)Revman5.2軟件對其進行Meta分析。 結(jié)果 本研究共納入符合標準的文獻有9篇，包括5篇中文文獻，4篇英文文獻，共有450例患者（自鎖托槽組240例，傳統(tǒng)托槽組210例）。Meta分析結(jié)果顯示在非拔牙矯治病例中： 1、自鎖托槽治療患者的上頜尖牙間距、上頜第一前磨牙間距及上頜第二前磨牙間距的增加值均大于傳統(tǒng)托槽，其差異均有統(tǒng)計學意義，，其具體值分別為：[MD=0.30,95%CI(0.04,0.55), P=0.02]，[MD=0.43,95%CI (0.17,0.70),P=0.001]，[MD=0.32,95%CI (0.08,0.56),P=0.008]。 2、自鎖托槽與傳統(tǒng)托槽相比，上頜第一磨牙間距變化的差異無統(tǒng)計學意義[MD=-0.01,95%CI (-0.25,0.24), P=0.66]。 3、自鎖托槽與傳統(tǒng)托槽相比，下頜尖牙間距、下頜第一前磨牙間距及下頜第二前磨牙間距變化的差異均無統(tǒng)計學意義，其具體值分別為：[MD=0.02,95%CI (-0.67,0.72), P=0.95]，[MD=0.26,95%CI (-0.62,1.14), P=0.57]，[MD=0.19,95%CI (-0.51,0.88), P=0.52]。 4、自鎖托槽與傳統(tǒng)托槽相比，下頜磨牙間距變化的差異有統(tǒng)計學意義[MD=0.59,95%CI(0.33,0.84), P＜0.01]。 5、上頜切牙唇傾度的增加量自鎖托槽要小于傳統(tǒng)托槽，兩者比較有統(tǒng)計學上的差異[MD=-3.25,95%CI (-4.99,-1.51), P=0.0003]；下頜切牙唇傾度的增加量自鎖托槽與傳統(tǒng)托槽無統(tǒng)計學上的差異[MD=-0.44,95%CI (-1.52,0.64), P=0.43]。 結(jié)論 應用自鎖托槽和傳統(tǒng)托槽行非拔牙矯治牙列擁擠時，自鎖托槽組在上頜尖牙區(qū)、上頜前磨牙區(qū)及下頜磨牙區(qū)的牙弓寬度擴大量比傳統(tǒng)托槽組要大；在上頜磨牙區(qū)、下頜尖牙區(qū)、下頜前磨牙區(qū)牙弓寬度的變化量二者間無明顯差異；無論自鎖托槽還是傳統(tǒng)托槽在非拔牙矯治時，上下前牙唇傾度均有不同程度的增加，但自鎖托槽組的上頜前牙唇傾度增加量要顯著小于傳統(tǒng)托槽組；下頜前牙唇傾度的增加量與傳統(tǒng)托槽相比并無顯著差異。
[Abstract]:Objective to compare the changes of the width of upper and lower arch and the degree of labial inclination of anterior teeth between self-locking brackets and traditional brackets in the treatment of mild and moderate crowding of dentition without extraction, so as to provide the basis for clinical application. Methods the database of PubMedus EMBASEI Cochrane clinical controlled trial and the full text database of Wanfang Journal of Science and Technology were searched by Evidence-Based Medicine (EBM) system. Chinese Biomedical Literature Database (CBM), Chinese Journal Full-text Database (CNKI), Weipu Chinese Science and Technology Journal Database (VIP) and manual retrieval, etc. To collect and compare the changes of the width of the upper and lower arch and the labial inclination of the anterior teeth between the self-locking brackets and the traditional brackets during the non-extraction correction, and to search for the deadline from December 31, 2013. The literature was screened by two evaluators according to the inclusion and exclusion criteria, and the quality evaluation and data extraction were carried out. The Meta-analysis was carried out by using Cochrane Cooperative Web Revman 5.2 software. Results A total of 9 articles were included in this study, including 5 articles in Chinese and 4 articles in English. A total of 450 patients (240 cases of self-locking bracket group) were included in this study. The results of Meta-analysis showed that: 1, the increase of maxillary canine spacing, maxillary first premolar distance and maxillary second premolar spacing in patients with self-locking bracket therapy were higher than those in traditional brackets, and the results of meta-analysis showed that: (1) the increase value of maxillary canine space, maxillary first premolar space and maxillary second premolar spacing in patients with self-locking brackets was higher than that in traditional brackets. The differences were statistically significant, and the specific values were as follows: [MDT 0.30C _ (95) CI (0.040.55), P _ (0.02)], [MDO _ (0.439) 95 CI (0.170.70) P _ (0.001)], [MDO _ (0.32) C _ (95) CI (0.080.56) P _ (0.008)]. There was no significant difference in the distance between maxillary first molars [MD-0.01 ~ 95CI (-0.250.24), P _ (0.66)] .3The distance of mandibular canines between self-locking brackets and traditional brackets was higher than that of traditional brackets. There was no significant difference in the distance between the first premolars and the second premolars, and the specific values were: [MDO 0.02 + 95CI (-0.67U 0.72), P < 0.95], [MD0.2695CI (-0.62n 1.14), P0.57], [MD0.19995 CI (-0.51U 0.88), P < 0.52]. There was a significant difference in the distance between mandibular molars [(0.33 鹵0.84) CI (0.33 鹵0.84), P < 0.01]. 5. The increase of labial inclination of maxillary incisors was smaller than that of traditional brackets, and there was a statistical difference between them [MD-3.2595 CI (-4.99-1.51), P < 0.0003]. There was no statistical difference between self-locking brackets and traditional brackets in the increase of labial inclination of mandibular incisors [MD-0.44 ~ 95CI (-1.52 鹵0.64), P _ (0.43)]. Conclusion when self-locking brackets and traditional brackets are used to treat dentition crowding, the arch width in the maxillary canine, maxillary premolar and mandibular molar areas in the self-locking bracket group is larger than that in the traditional bracket group. There was no significant difference in arch width between the maxillary molar region, mandibular canine region and mandibular premolar region. However, the increase of labial inclination in the self-locking bracket group was significantly lower than that in the traditional bracket group, and there was no significant difference between the mandibular anterior tooth labial tilting degree and the traditional bracket group.
