Miniscrews are devices that allow for absolute skeletal anchorage. However, their use has a higher failure rate (10-30%) than dental implants (10%). To overcome these flaws, chemical and/or mechanical treatment of the surface of miniscrews has been suggested. There is no consensus in the current literature about which of these methods is the gold standard; thus, our objective was to carry out a systematic review and meta-analysis of the literature on surface treatments of miniscrews. The review protocol was registered (PROSPERO CRD42023408011) and is in accordance with the PRISMA guidelines. A bibliographic search was carried out on PubMed via MEDLINE, Cochrane Library, Embase and Web of Science. The initial search of the databases yielded 1684 results, with 98 studies included in the review, with one article originating from the search in the bibliographic references of the included studies. The results of this systematic review show that the protocols of miniscrew surface treatments, such as acid-etching; sandblasting, large-grit and acid-etching; photofunctionalization with ultraviolet light; and photobiomodulation, can increase stability and the success of orthodontic treatment. The meta-analysis revealed that the treatment with the highest removal torque is SLA, followed by acid-etching. On the other hand, techniques such as oxidative anodization, anodization with pre-calcification and heat treatment, as well as deposition of chemical compounds, require further investigation to confirm their effectiveness.
微型螺钉是一种可实现绝对骨锚固的装置。然而，与牙种植体（10%）相比，其使用的失败率更高（10 - 30%）。为克服这些缺陷，有人提出对微型螺钉表面进行化学和/或机械处理。目前的文献对于哪种方法是金标准尚无共识；因此，我们的目标是对微型螺钉表面处理的文献进行系统综述和荟萃分析。该综述方案已注册（PROSPERO CRD42023408011），并符合PRISMA指南。通过MEDLINE、Cochrane图书馆、Embase和科学网在PubMed上进行了文献检索。对数据库的初步检索产生了1684条结果，其中98项研究纳入了该综述，有一篇文章来自对纳入研究的参考文献检索。这项系统综述的结果表明，微型螺钉表面处理方案，如酸蚀；喷砂、大颗粒喷砂和酸蚀；紫外线光功能化；以及光生物调节，可以提高正畸治疗的稳定性和成功率。荟萃分析显示，去除扭矩最高的处理方法是SLA，其次是酸蚀。另一方面，诸如氧化阳极氧化、预钙化阳极氧化和热处理以及化合物沉积等技术，需要进一步研究以证实其有效性。
