Patent ID: 7871561

Claim:
A method for producing artificial bone, comprising the steps of: obtaining a porous body having a porosity and an average pore size lying within a range enclosed with lines connecting the X (porosity (%)) and Y (average pore size (μm)) coordinates of points A (46, 180), B (46, 520), C (50, 520), D (72, 220), and E (72, 180) by mixing granules having a granule size in the range of 0.1 to 2.0 mm, composed of a titanium or a titanium alloy powder having a maximum particle size of 180 μm or less and an organic binder, with a particulate pore-forming material, pressure-molding the mixture to obtain a molded body, and firing the molded body; bringing the porous body into contact with an aqueous alkali solution; then bringing the porous body into contact with water until the alkali concentration of the porous body becomes 0.3% or less; and subsequently heating the porous body at 60 to 650° C.
