초록
Purpose: The objective of this study was to compare the osseointegration of SLA® to these of Joy 1 implant®. Materials and Methods: In 6 beagle dogs, 3rd and 4th mandibular premolar were extracted bilaterally. After 3 months, four transmucosal screw-shaped implants were placed in each mandibular edentulous premolar region. Control groups were SLA® and experimental groups were Joy 1 implant®. The implants were allowed to heal for 4 or 8 weeks. At the end of the experiment, the dogs were sacrificed and each of implant sites was dissected and processed for histomorphometric analysis. Results: Histomorphometric analysis showed direct osseous integration for both implants. No significant difference between both types of implants could be detected after 4 and 8 weeks healing periods in bone to implant contact (BIC) and bone ingrowth (BI). Conclusion: The results indicate that there was no difference in osseointegration between SLA® implant and Joy 1 implant® regarding BIC and BI, Joy 1 implant® showed similar histological response with SLA® implant.
