Nanotechnology has contributed important innovations to medicine and dentistry, and has also offered various applications to the field of orthodontics. Intraoral appliances must function in a complex environment that includes digestive enzymes, a diverse microbiome, mechanical stress, and fluctuations of pH and temperature. Nanotechnology can improve the performance of orthodontic brackets and archwires by reducing friction, inhibiting bacterial growth and biofilm formation, optimizing tooth remineralization, improving corrosion resistance and biocompatibility of metal substrates, and accelerating or decelerating orthodontic tooth movement through the application of novel nanocoatings, nanoelectromechanical systems, and nanorobots. This comprehensive review systematically explores the orthodontic applications of nanotechnology, particularly its impacts on tooth movement, antibacterial activity, friction reduction, and corrosion resistance. A search across PubMed, the Web of Science Core Collection, and Google Scholar yielded 261 papers, of which 28 met our inclusion criteria. These selected studies highlight the significant benefits of nanotechnology in orthodontic devices. Recent clinical trials demonstrate that advancements brought by nanotechnology may facilitate the future delivery of more effective and comfortable orthodontic care.
纳米技术为医学和牙科做出了重要的创新贡献，也为正畸领域提供了各种应用。口腔内器械必须在包括消化酶、多样化的微生物组、机械应力以及 pH 值和温度波动的复杂环境中发挥作用。纳米技术可以通过减少摩擦、抑制细菌生长和生物膜形成、优化牙齿再矿化、提高金属基底的耐腐蚀性和生物相容性，以及通过应用新型纳米涂层、纳米机电系统和纳米机器人来加速或减速正畸牙齿移动，从而改善正畸托槽和弓丝的性能。这篇全面的综述系统地探讨了纳米技术在正畸中的应用，特别是其对牙齿移动、抗菌活性、减少摩擦和耐腐蚀性的影响。通过对 PubMed、Web of Science 核心合集和 Google Scholar 的搜索，共获得了 261 篇论文，其中 28 篇符合我们的纳入标准。这些选定的研究强调了纳米技术在正畸器械中的重要优势。最近的临床试验表明，纳米技术带来的进步可能有助于未来提供更有效和更舒适的正畸护理。
