Abstract

Abstract: Objective To observe the osseointegration effect of hydrophilic surface modified dental implants. Methods four beagle dogs were randomly divided into 2week, 4week, 8week and 12 week groups. Four hydrophilic surface modified dental implants were implanted into the mandible of 2 months after tooth extraction in each group. Results the ISQ, critical rotation torque and osseointegration rate were significantly increased at 4 weeks compared with 2 weeks; the critical rotation torque and osseointegration rate were significantly increased at 8 weeks compared with 4 weeks; the osseointegration rate was significantly increased at 12 weeks compared with 8 weeks. Conclusion Hydrophilic surface modified surface treatment promotes osseointegration of implants.

Key words: hydrophilic surface modification, osseointegration, Beagle dog
