Abstract
|
|
|
The present study was performed to evaluate histomorphological difference in various surface-treated implants in beagle. Implants(Implantium®, Dentium Co. Korea) with pure titanium machined surface, acid treated surface, and Al2O3(50~100μm)blasted with acid treated surface were used in this study. All mandibular premolars of 1.5~2 year old male beagle dogs were extracted. At 3 months after extraction, the implants(Φ 4mm, l 6mm) were installed. The beagle were sacrificed at 1, 3 months after installation and then tissues including implants were prepared for non-decalcified specimens. These specimens were analyzed comparatively under light microscope.
The results of this study were as follow
1. Higher rate of osseointegration were showed in the Al2O3(50~100μm)blasted with acid-treated surface.
2. Increased osseointegration were showed in the Al2O3(50~100μm)blasted with acidtreated surface with time.
3. Higher maturation of integration were showed in the Al2O3(50~100μm)blasted with acid-treated surface.
In conclusion, surface treatment of Al2O3blasted with acid might be considered to shorten healing time and improve success rate as increasing contact of implant and bone.
