The present study was performed to evaluate the surface roughness and effect of Tetracycline-HCI on the change of implant surface microstructure according to application time. Ti$O_2$ surface Implant was utilized. Implant surface was rubbed with 50mg/ml Tetracycline-HCI solution for 0.5min, 1min, 1.5min, 2min, 2.5min and 3min respectively in the Tetracycline-HCI group. Then, specimens were measured surface roughness and processed for scanning electron microscopic observation. The results of this study were as follows. 1. Ti$O_2$ blast implant surface showed increased surface roughness 1.5 minute after treatment with Tetracycline-HCI. But, there were not significant differences in saline group after treatment. 2. Tetracycline-HCI 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-HCI group and saline group, there were difference in surface roughness change and SEM micro-morphology. Tetracycline-HCI have influence on Ti$O_2$ blast implant surface. In conclusion, the detoxification with 50mg/ml Tetracycline-HCI must be applied respectively with different time according to various implant surfaces.
