“…In the case of implant surface made with electron beam melting (EBM), the fabricated surface asperity was compared with that is manufactured with machining, and there was no significant difference. However, there was a difference of bioactivity in in-vivo experiment performed with rabbit femur [3] In our previous report, we investigated the influence of surface asperity of implant model on bioactivity by means of an in-vivo experiment [5]. The square pole implant models were fabricated by SLM and they were introduced into the rat femurs.…”

Square pole implant models of Ti-6Al-4V were fabricated by selective laser melting (SLM) and osteoconductivity was investigated on their surface. 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.
