<P>PROBLEM TO BE SOLVED: To provide a bone regeneration medical material which is easily bonded to a bone by growing the bone inside a porous body. <P>SOLUTION: The bone regeneration medical material is manufactured by obtaining a polyurethane foamed intermediate body containing titanium powder by mixing a prepolymer, which has a terminal isocyanate group formed by making polyole having active hydrogen and polyisocyanate react, and slurry, which is formed by suspending the titanium powder in an aqueous dispersion medium, and making them react, then executing heat treatment to the intermediate body, and degreasing and sintering the intermediate body. The bone regeneration medical material comprises a foamed titanium material containing interconnected bubbles formed by interconnecting a plurality of bubbles. <P>COPYRIGHT: (C)2011,JPO&INPIT |
