The models have 3 types of surfaces; top surface, side surface, and polished surface. The surfaces have each different surface roughness and the influence of the roughness on the osteoconductivity was observed in-vivo experiment. The models were implanted in rat femurs and observed after 2 and 8 weeks. We observed the amount of hard tissue produced on the surfaces in the cut-off cross section of the femurs with the model by means of an optical microscope and bone-implant contact ratio (RB-I) was evaluated. As the result, in the case of 2 weeks-raised rats, the RB-I of the polished surface was the highest of all surfaces. The RB-I of the surface was however the lowest and that of the top surface was the highest in the case of 8 weeks-raised rats.
