BONE PROSTHETIC MATERIAL AND METHOD FOR PRODUCING THE SAME

PROBLEM TO BE SOLVED: To provide a bone prosthetic material allowing reduction of a period needed for formation of a new bone, and to provide a method for producing the same.SOLUTION: This bone prosthetic material contains a granule group, which consists of -tricalcium phosphate porus bodies, and wherein each granule has a particle diameter ≥1 μm and ≤100 μm. The method for producing the bone prosthetic material includes a classification step S4 of classifying the granule group wherein each granule has the particle diameter ≥1 μm and ≤100 μm from the granule group consisting of the -tricalcium phosphate porous bodies and having different particle diameters by an air classification method. Thereby, serum protein abundantly sticks fast to the granule group transplanted to a bone loss part, so that osteoblasts can be rapidly induced to the granule group and be engrafted.
