US 2003/0193106 A1 · Artificial bone graft substitute using calcium phosphate compounds and method of manufacturing the same

Abstract

A bone graft substitute using magnesium substituted calcium phosphate compounds and a method of manufacturing the same is provided in which the bone graft substitute is used for recovering bones damaged due to a bone fracture. The method of manufacturing a bone graft substitute includes the steps of mixing powdered calcium pyrophosphate and a magnesium included compound to thereby obtain a composition, pressure-forming the compositions to obtain a plastic body; and sintering the plastic body.

Dependent claims

A method of manufacturing a bone graft substitute, comprising the steps of:

mixing each powder of calcium pyrophosphate (Ca2P2O7) or calcium pyrophosphate including tricalcium phosphate (Ca3(PO4)2) of 10 weight percent [wt %] or less, and a magnesium included compound, to thereby obtain a composition;
pressurizing the composition or forming a porous body, to thereby obtain a green body;
and
sintering the green body.
