PURPOSE: A method for preparing bone compositions, bone compositions prepared by the same, and an artificial bone including the same are provided to improve osteoconductivity and quality. CONSTITUTION: A method for preparing bone compositions comprises the following steps: preparing an organic-inorganic composite by mixing one or more carrier materials selected from a calcium aqueous solution, phosphoric acid, gelatin, collagen, chondroitin sulfate, and glycosaminoglycan with one or more bonding regulating materials selected from chitosan, dextrin, polyvinyl acrylate (PVA), polyacrylamide (PAA), and polymethyl methacrylate (PMMA) at pH 6.5-8.5; filtering and drying the organic-inorganic composite under carbon dioxide-free atmosphere. The organic-inorganic composite includes a compound including Ca and P, a carrier material, and a bonding regulating material. |
