Statement of problem

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.

Purpose

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.

Material and methods

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.

Results

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.

Conclusions

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.

高功率激光辐照表面处理对钛牙种植体表面性能影响的系统综述

问题陈述

高功率激光照射可能是一种很有前途的钛牙种植体表面处理方法。然而，缺乏关于高功率激光照射对钛表面不同性能影响的系统评价。

目的

本系统综述的目的是分析高功率激光辐照表面处理对钛及其合金表面性能的影响。

材料与方法

检索了 PubMed、LILACS、COCHRANE 图书馆和 Science Direct 数据库，并收录了过去 10 年发表的文章。在最初确定的 725 篇文章中，27 篇是在全面阅读并应用纳入和排除标准后选择的。

结果

评估的研究表明，根据所使用的设置和参数，激光辐照处理促进了钛表面特性的变化。通常，较低的速度和较高的扫描次数会增加粗糙度。激光表面处理促进了更多氧的包裹，提高了钛的润湿能力。此外，激光处理改善了涂层的附着力。

结论

激光处理后钛的表面特性发生了变化。然而，确定具有特定参数的协议对于优化结果是必要的。
