To evaluate the quantitative effects of miniscrew supported appliances for maxillary molar distalization in Class II malocclusion.
The systematic search included MEDLINE, EMBASE, CINAHL, PsychINFO, Scopus, and key journals and review articles. The date of the last search was January 30, 2017. Methodological quality of the retrospective studies was graded by means of the Quality Assessment Tool for Quantitative Studies, developed for the Effective Public Health Practice Project (EPHPP) and prospective studies by means of Newcastle-Ottawa Scale.
In total, 298 studies were identified for screening, and 14 studies were eligible. The Quality Assessment Tool for Quantitative Studies rated all of the four included retrospective studies as moderate. The Newcastle-Ottawa Scale rated seven studies as high quality and three studies as low quality. The mean molar distalization values varied from 1.8 mm to 6.4 mm. Mean distal tipping of molars varied from 1.65° to 11.3°. The mean distal movement of premolars and incisors varied from 1.75 mm to 5.4 mm and 0.1 mm to 2.7 mm, respectively.
Miniscrew-supported appliances are effective in molar distalization with distal movement of premolars with minimal anchorage loss and distal tipping of the molar teeth.
评估微螺钉支抗装置远移上颌磨牙在安氏Ⅱ类错牙合中的定量效果。
系统检索 MEDLINE、EMBASE、CINAHL、PsychINFO、Scopus 和主要期刊及综述文章。最后检索日期为 2017 年 1 月 30 日。采用有效公共卫生实践项目（EPHPP）制定的定量研究质量评估工具对回顾性研究进行方法学质量评价，前瞻性研究采用 Newcastle-Ottawa 量表进行评价。
共筛选出 298 项研究，其中 14 项符合纳入标准。定量研究质量评估工具评价 4 项纳入的回顾性研究均为中度。Newcastle-Ottawa 量表评价 7 项研究为高质量，3 项为低质量。磨牙平均远移值为 1.8mm 至 6.4mm。磨牙平均远倾值为 1.65°至 11.3°。前磨牙和切牙平均远移值为 1.75mm 至 5.4mm 和 0.1mm 至 2.7mm。
微螺钉支抗装置远移上颌磨牙有效，磨牙远中移动以支抗丧失最小和磨牙远倾为主。
