Abstract
The use of dental implants in the partial and complete edentulism has become the primary treatment regimen in the modern dentistry. Erbium chromium-doped yattrium-scandium-gallium-garnet (Er,Cr:YSGG) laser is most often used in dentistry in implant surgery and management of peri-implantitis. The aim of the present study was to assess the biocompatibility of Er,Cr:YSGG laser-treated titanium alloy (Ti-6Al-4V) and its surface characteristics to understand the impact of the laser on the titanium alloy surfaces.
Materials and methods
A total of 20 discs of titanium alloy (Ti-6Al-4V) were used. Ten discs were irradiated with Er,Cr:YSGG laser which was operating in a normal room atmosphere and temperature at power 2 W. Biocompatibility was investigated in vitro via MTT assay. Surface analysis of laser-treated and laser-untreated discs was examined with a scanning electron microscope.
Result
Laser-treated group showed superior cell viability compared to untreated group. No undesirable changes were observed by SEM.
Conclusion
We can conclude that Er,Cr:YSGG laser safely could improve the biocompatibility of dental implant.
