Micromorphometric change of TiO2 b last i mplant surface conditioned with tetracycline-HCl / 대한치주과학회지

ABSTRACT

The present study was performed to evaluate the surface roughness and effect of Tetracycline-HCl on the change of implant surface microstructure according to application time. TiO2 surface Implant was utilized. Implant surface was rubbed with 50mg/ml Tetracycline-HCl solution for 0.5min, 1min, 1.5min, 2min, 2.5min and 3min respectively in the Tetracycline-HCl group. Then, specimens were measured surface roughness and processed for scanning electron microscopic observation. The results of this study were as follows. 1. TiO2 blast implant surface showed increased surface roughness 1.5 minute after treatment with Tetracycline-HCl. But, there were not significant differences in saline group after treatment. 2. Tetracycline-HCl group showed changed surface micro-morphology in SEM after 1.5 minute. There were not significant differences in saline group after treatment. 3. Between Tetracycline-HCl group and saline group, there were difference in surface roughness change and SEM micro-morphology. Tetracycline-HCl have influence on TiO2 blast implant surface. In conclusion, the detoxification with 50mg/ml Tetracycline-HCl must be applied respectively with different time according to various implant surfaces.
