The purpose of this study was to evaluate the effect of resorbable membrane and xenogenic graft materials on implant stability and peri-implant tissue reaction in defect site. The experimental groups are classified into 4 groups-control(groupⅠ), Bio-Oss® and BioMesh®(groupⅡ), BioMesh®(groupⅢ), DEMBONE® and BioMesh®(groupⅣ). 4 titanium implants were installed into both tibias in each of 8 rabbits. Resonance Frequency Analyser(RFA) value were measured by RFA per every other four weeks. The rabbits were sacrificed after 4 months for implant stability analysis and histologic analysis. The results were as follows ; 1. In comparision of RFA values between experimental groups, there was no significant difference. 2. In comparision of RFA values according to experimental period, there were significant differences among the all periods(p<0.05). 3. Even though there were some degree of variations, bone growth around the exposed portion of implants were observed in all experimental groups. From the results above, application of Xenogenic Grafts and Resorbable Membrane did not affect RFA value. It is considered that RFA value is clinically significant for measuring the stability of implant in the view of increasing the RFA value according to experimental periods.
