【摘要】：目的比较种植体支抗与传统方法(J钩、多用途弓)压低上颌前牙的临床疗效。方法计算机检索Cochrane Library、PubMed、EMbase、维普、万方及知网等在线数据库,收集比较种植体支抗与传统方法压低上颌前牙的随机对照试验及病例对照试验,并追查纳入文献的参考文献。经筛选、资料提取和质量评价后,采用RevMan5.1软件进行Meta分析。结果共纳入11个研究文献,其中关于种植体与J钩比较的文献有6篇,154例患者;关于种植体与多用途弓比较的文献有5篇,127例患者。Meta分析结果显示,(1)与J钩组相比,种植体组U1-PP距变化量较多(P0.001),覆变化量较多(P=0.001),治疗时间较短(P0.001),SN-OP角增大量较少(P=0.004),U6-PP距变化量较少(P=0.020);两组的覆盖变化量、牙根吸收量差异无统计学意义(P0.05)。(2)与多用途弓组相比,种植体组U1-PP距变化量较多(P=0.010),U6-PP角增大量较少(P0.001);两组的U1-PP距、U1-PP角、U6-PP距、U6水平向移动距离、覆、覆盖、疗程、牙根吸收量差异无统计学意义(P0.05)。结论种植体与抗压低上颌前牙疗效优于传统方法(J钩、多用途弓),压低前牙量多、时间短、患者较舒适,两者牙根吸收量相当。
[Abstract]:Objective to compare the clinical efficacy of implant Anchorage and traditional method (J hook, multi-purpose arch) in the depression of maxillary anterior teeth. Methods the online databases such as Cochrane Library PubMedbase, Wiper, Wanfang and Zhiwang were searched, and the randomized controlled trials and case-control trials were collected and compared between implant Anchorage and traditional methods to lower the maxillary anterior teeth, and the references included in the literature were followed up. After screening, data extraction and quality evaluation, Meta-analysis was carried out with Revman 5.1 software. Results A total of 11 literatures were included, of which there were 6 articles on the comparison of implant and J hook in 154 patients, and 5 articles on the comparison of implant and multipurpose arch in 127 patients. Meta-analysis showed that: (1) compared with J hook group, In implant group, U1-PP distance changed more (P0. 001), overlying change was more (P0. 001), treatment time was shorter (P0. 001) and SN-OP angle increased less (P0. 004) U6-PP distance changed less (P0. 020), there was no significant difference between two groups (P0.05). (2). In the implant group, the distance between U1-PP and U6-PP increased more (P0. 010) and the angle of U6-PP increased less (P0. 001), and there was no significant difference in the distance of U1-PP from U1-PP to U6-PP from U6 to U6 horizontal movement, coverage, course of treatment, root resorption (P0.05). Conclusion the curative effect of implants and anti-depression maxillary anterior teeth is better than that of traditional methods (J hook, multi-purpose arch).
