目的:比较微种植体(MI)和常规支抗(CA)在正畸拔牙治疗中垂直控制青春期生长高峰期后的II级成人和青少年的有效性。
方法:通过Cochrane中央对照试验注册中心(CENTRAL)进行文献检索,PubMed,EMBASE,WebofScience,中国国家知识基础设施(CNKI),万方数据库,VIP,中国生物医学(CBM),和其他来源,从成立到2021年12月。包括随机临床试验(RCT)和对照临床试验(CCT)。采用95%置信区间(CI)进行平均差(MD)。下颌平面变化的荟萃分析,上、下磨牙的垂直变化,咬合平面的变化,SNB,下巴位置,并进行了侧写。
结果:在数据库搜索中总共识别出10,669条记录,19项研究(10项RCT和9项CCT)纳入最终分析。与CA相比,MI显着降低下颌平面角并侵入上磨牙。下磨牙的垂直变化没有发现显着差异,咬合平面,SNB,下巴位置,和配置文件。
结论:在青春期生长高峰后的II级成人和青少年正畸拔除治疗中,MI似乎比CA更有效。
结论:在考虑对II类患者进行垂直控制时,应优先考虑MI,这有利于下颌骨的逆时针旋转或至少防止轮廓的恶化。
OBJECTIVE: To compare the effectiveness of micro-implant (MI) and conventional anchorage (CA) in vertical control during orthodontic extraction treatment of class II adults and adolescents after pubertal growth peak.
METHODS: Literature search was conducted through Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, China Biology Medicine (CBM), and other sources, from inception to December 2021. Randomized clinical trials (RCTs) and controlled clinical trials (CCTs) were included. Mean differences (MDs) with 95% confidence intervals (CIs) were conducted. A meta-analysis concerning change of mandibular plane, vertical change of upper and lower molar, change of occlusal plane, SNB, chin position, and profile was carried out.
RESULTS: A total of 10,669 records were identified in the database search, and 19 studies (10 RCTs and 9 CCTs) were included in the final analysis. Compared with CA, MI significantly decreased mandibular plane angle and intruded upper molars. No significant difference was found in vertical change of lower molars, occlusal plane, SNB, chin position, and profile.
CONCLUSIONS: MI seems to be more effective than CA in vertical control during orthodontic extraction treatment of class II adults and adolescents after pubertal growth peak.
CONCLUSIONS: MI should be given priority when considering the vertical control of class II patients, which is beneficial to the counterclockwise rotation of mandible or at least prevention of deterioration of the profile.
