High-power laser irradiation may be a promising treatment for titanium dental implant surfaces. However, systematic reviews of the influence of high-power laser irradiation on the different properties of titanium surfaces are lacking.
The purpose of this systematic review was to analyze the influence of surface treatment by high-power laser irradiation on the surface properties of titanium and its alloys.
The PubMed, LILACS, COCHRANE library, and Science Direct databases were searched, and articles published in the last 10 years were included. Of the 725 articles initially identified, 27 were selected after full reading and the application of inclusion and exclusion criteria.
The studies evaluated showed that laser irradiation treatment, depending on the settings and parameters used, promoted changes in the surface properties of titanium. In general, lower speed and a higher number of scans increased roughness. Laser surface treatment promoted the inclusion of more oxygen and improved the wetting capacity of titanium. Additionally, laser treatment improved the adherence of coatings.
Changes in the surface properties of titanium after laser treatment have been demonstrated. However, determining protocols with specific parameters is necessary to optimize the results.
高功率激光辐照可能是一种有前途的钛牙科植入物表面处理方法。然而，缺乏对高功率激光辐照对钛表面不同性能影响的系统评价。
本系统评价的目的是分析高功率激光辐照对钛及其合金表面性能的影响。
检索了 PubMed、LILACS、COCHRANE 图书馆和 Science Direct 数据库，并纳入了过去 10 年发表的文章。在对 725 篇初步确定的文章进行全文阅读并应用纳入和排除标准后，选择了 27 篇文章。
评估的研究表明，激光辐照处理根据使用的设置和参数的不同，会导致钛表面性能发生变化。一般来说，较低的速度和更多的扫描次数会增加粗糙度。激光表面处理促进了更多氧的掺入，并提高了钛的润湿性。此外，激光处理还提高了涂层的附着力。
已经证明了钛经激光处理后表面性能的变化。然而，需要确定具有特定参数的方案来优化结果。
