Abstract
|
|
|
The present study was performed to evaluate the effect of tetracycline-HCL on the change of
implant surface microstructure according to application time. Implant with pure titaniummachined surface, HA-coated surface and TiUniteTM surface were utilized. Implant surface
was rubbed with 50㎎/㎖ tetracycline-HCL solution for ½min., 1min., 1½min., 2min., and 2½min.
respectively in the test group. Then, specimens were processed for scanning electron microscopic observation.
The results of this study were as follows.
1. Both test and control group showed a few shallow grooves and ridges in pure titaniummachined surface implants. There were not significant differences between two groups.
2. In HA-coated surfaces, round particles were deposited irregularly. The roughness of
surfaces conditioned with tetracycline-HCL was lessened and the cracks were increased
relative to the application time.
3. The anodic oxidized surfaces showed the craterous structures. The surface conditioning
with tetracycline-HCl didn't influence on its micro-morphology.
In conclusion, the detoxification with 50㎎/㎖ tetracycline-HCL must be applied respectively
with different time according to various implant surfaces.2)
