| Research Abstract |
Smart bone plates showing the Young's modulus decrease were developed to suppress the stress-shielding effect in this study. Firstly, a porous Co-Cr-Mo alloy was fabricated using a selective laser melting process. The porous Co-Cr-Mo alloy contains three dimensionally crossed pore channel and the Young's modulus was close to the human bone Secondly, the hydroxyapatite was introduced through the pore cannel and sintered. The Young's modulus of the composites increased compared to that of the porous Co-Cr-Mo alloy, suggesting that the modulus can be controlled by the integration of bio-degradable materials.
