Document Type and Number:
WIPO Patent Application WO/2005/055886
Kind Code:
A1
Abstract:
A bone supplementing material enabling the smooth, secure, and safe supplement to a broken bone section. The bone supplementing material (1) formed in a pellet shape is used by supplementing multiple pieces of supplementing materials to one broken bone section. The bone supplementing material (1) is formed of a solid surrounded by a plurality of faces, and one face (11) to the other face (12) in at least a pair of faces opposed to each other among the plurality of faces is tilted by a specified angle Ѳ. The angle Ѳ is desirably 10 to 60°. The bone supplementing material (1) desirably meets either of such requirements that a porosity is 75% or less and a crushing strength is 15 MPa or higher, and more desirably meets both of these requirements. The size of the bone supplementing material (1) is 13 to 239 mm3. Also, the bone supplementing material (1) is formed of a calcium phosphate-based compound with a Ca/P ratio of 1.0 to 2.0.
