| Abstract: | The biocompatibility of implant material in the human body is related to the interaction between the living cells and implant material surface. Not all implant material surfaces have truly long-term biocompatibility, even though many biomaterials have been used for clinical implantation. Therefore, various modification techniques have been considered to increase the surface biocompatibility of titanium (Ti) 1-6 which is one of the most popular implant materials for clinical applications. To our knowledge, a simple but efficient method for implant surface modification is not well developed, and currently still under investigation. Recently, a new generation of Erbium, Chromium: Yttrium, Scandium, Gallium, Garnet (Er,Cr:YSGG) laser uses a combination of laser energy, water, and air to ablate enamel, dentin, bone, and soft tissue 7-12. The wavelength (2780 nm) of the Er,Cr:YSGG laser has an affinity for water. The ablation is accomplished by hydrokinetic energy that prevents the temperature from rising. Although the Er,Cr:YSGG hydrokinetic laser system is widely used for dental purposes, its potential application to implant biocompatibility modification is still not available in the literature. This study proposed a fast and useful surface modification method, i.e. Er,Cr:YSGG laser-powered hydrokinetic system, for improving the biocompatibility of Ti metal. The initial biocompatibility on the laser-treated Ti surface was evaluated. |
