ABSTRACT
PURPOSE:
The aim of this study was to evaluate the effect of ErYAG laser on microstructure and roughness of TiO2 blasting implant surface. MATERIALS ANDMETHODS:
Ten TiO2 blasting implant were used in this experiment. One implant was control group, and nine TiO2 blasting implant surfaces were irradiated with ErYAG laser under 100 mJ/pulse, 140 mJ/pulse, and 180 mJ/pulse condition for 1 min, 1.5 min, and 2 min respectively. Optical interferometer and scanning electron microscopy was utilized to measure roughness and microstructure of specimens.RESULTS:
The surface roughness was decreased after ErYAG laser irradiation in all groups, but there was no significant difference. 100 mJ/pulse and 140 mJ/pulse group did not alter the TiO2 blasting implant surface in SEM study while 180 mJ/pulse group altered the TiO2 blasting implant surface. Implant surfaces showed melting, microfracture and smooth surface in 180 mJ/pulse group.CONCLUSION:
Detoxification of implant surface using ErYAG laser must be irradiated with proper energy output and irradiation time to prevent implant surface alteration.
