Introduction: Hydroxyapatite(HA) coating implant can accelerate osseointegration, however, there are many controversies.
Materials and Methods:This study examined the early osseointegration of two types of hydroxyapatite coated implants. Twelve adult male miniature pigs (Medi Kinetics Micropigs, Medi Kinetics Co., Ltd., Susan, Korea) were used in this study. In the implants placed in the mandible, a histo-morphometric evaluation was performed to evaluate the bone-implant contact (BIC) ratio.
Results: The SIC ratio increased with time. TS Ⅲ HA and Zimmer HA were not significantly different (P＞0.05). At 8 weeks, the BIC of Zimmer HA was higher than TS Ⅲ HA, but there was no significant difference (P＞0.05).
Conclusion:HA coated implants will accelerate early osseointegration.
