Titanium (Ti) is commonly employed therapeutically in many medical sectors associated with bone healing because of its superior mechanical properties and capacity to osseointegrate in the host bone tissue. The titanium surfaces may now be functionalized to offer additional and potentially valuable features. This review article discusses many titanium implant surface modifications, emphasizing their biological significance and the challenges that each one mainly addresses. Before reviewing the genuine reason for titanium surface modification in implanted devices, we briefly explore the process of osseointegration, enhancement of antibacterial properties, biocompatibility, and the historical significance of titanium as an implantable material, and the significant challenges involved. The various physical and chemical alterations that could take place on Ti surfaces are next examined. The rest of our talk will focus on creating inorganic and organic coatings for implanted Ti devices. Finally, we present a synopsis of the surface modification strategies currently being evaluated in clinical settings.
This systematic review aims to evaluate research on titanium implants with significant surface modifications, coatings, and antibacterial capabilities.
Following the PRISMA paradigm, we searched for three electronic databases (Web of Science, PubMed Central, and Google Scholar) using the keywords "titanium implants," "titanium surface modification," and "titanium osseointegration," and "titanium antibacterial activity."
We identified 1,39,336 articles overall that were published between 2012 and 2021, and we then focused on 8917 articles that concentrated on a particular topic. Clear inclusion and exclusion criteria were used in a rigorous screening procedure. Articles that didn't meet certain requirements (were irrelevant, used incorrect techniques, had unsuitable data values, or were only brief letters or communications) were eliminated. Finally, 120 research publications in total are taken into account for this extensive systematic review.
The report summarises current information on titanium implants with significant surface modifications, antibacterial activity, and coatings. It also gives some strong recommendations for future study topics.
钛(Ti)因其卓越的机械性能以及在宿主骨组织中实现骨整合的能力,在许多与骨愈合相关的医学领域中被广泛应用于治疗。如今,钛表面可以进行功能化处理,以提供更多潜在的有价值特性。这篇综述文章讨论了多种钛植入物表面改性方法,重点阐述了它们的生物学意义以及各自主要解决的挑战。在回顾植入装置中钛表面改性的真正原因之前,我们简要探讨骨整合过程、抗菌性能增强、生物相容性以及钛作为可植入材料的历史意义,以及其中涉及的重大挑战。接下来将研究钛表面可能发生的各种物理和化学变化。我们后续的讨论将聚焦于为植入式钛装置制备无机和有机涂层。最后,我们概述了目前正在临床环境中评估的表面改性策略。
本系统综述旨在评估对具有显著表面改性、涂层和抗菌能力的钛植入物的研究。
遵循PRISMA范式,我们使用关键词“钛植入物”“钛表面改性”“钛骨整合”和“钛抗菌活性”在三个电子数据库(科学网、PubMed Central和谷歌学术)中进行搜索。
我们总共识别出2012年至2021年间发表的139336篇文章,然后聚焦于8917篇专注于特定主题的文章。在严格的筛选过程中使用了明确的纳入和排除标准。不符合某些要求(不相关、技术不正确、数据值不合适或只是简短的信函或通讯)的文章被排除。最后,本广泛的系统综述总共考虑了120篇研究出版物。
该报告总结了有关具有显著表面改性、抗菌活性和涂层的钛植入物的当前信息。它还为未来的研究主题提供了一些有力的建议。
