This study aimed to systematically analyze the effect and stability of miniscrew-assisted rapid palatal expansion (MARPE) to provide a reference for the clinical treatment of patients with maxillary transverse deficiency (MTD).
We searched PubMed, Science Direct, Web of Science, Embase, Cochrane Library, CNKI, and Wanfang Database for relevant studies published before February 18, 2021 and selected them according to the eligibility criteria. The Cochrane Handbook for Systematic Reviews (version 5.1.0) criteria were used for the quality assessment of randomized controlled trials, while the scoring protocol of the methodological index for non-randomized studies was used for non-randomized controlled trials. Statistical analysis was performed using the RevMan5.3 software.
All the included studies showed a relatively high success rate of expansion. The changes in both the intermolar and alveolar widths after MARPE were statistically significant. MARPE exhibited greater skeletal expansion effects than did conventional RPE. The midpalatal suture was opened in parallel after MARPE. A small amount of relapse was observed 1 year after expansion. MARPE caused tooth inclination and a decrease in alveolar height, but it was less significant than in conventional RPE.
MARPE may be an effective treatment modality for patients with MTD. It causes great transverse skeletal expansion in late adolescence. In comparison to conventional RPE, MARPE has lower detrimental periodontal effects and has certain clinical advantages.
本研究旨在系统分析微型螺钉辅助快速腭扩展（MARPE）的效果和稳定性，为上颌横向发育不足（MTD）患者的临床治疗提供参考。
检索PubMed、Science Direct、Web of Science、Embase、Cochrane图书馆、中国知网和万方数据库，查找2021年2月18日前发表的相关研究，并根据纳入标准进行筛选。随机对照试验的质量评估采用Cochrane系统评价手册（第5.1.0版）标准，非随机对照试验采用非随机研究方法学指标评分协议。使用RevMan5.3软件进行统计分析。
所有纳入研究均显示出较高的扩展成功率。MARPE术后磨牙间宽度和牙槽宽度的变化具有统计学意义。与传统快速腭扩展（RPE）相比，MARPE表现出更大的骨骼扩展效果。MARPE术后腭中缝平行打开。扩展后1年观察到少量复发。MARPE导致牙齿倾斜和牙槽高度降低，但比传统RPE的影响小。
MARPE可能是治疗MTD患者的一种有效治疗方式。它在青春期末期可引起较大的横向骨骼扩展。与传统RPE相比，MARPE对牙周的不良影响较小，具有一定的临床优势。
