A prosthetic filler for a living body having excellent storage properties and
handlability
is disclosed. The prosthetic filler includes calcium phosphate granules and porous
small chips made of an organic material for binding these calcium phosphate granules
to each other. The prosthetic filler is made by mixing the calcium phosphate granules
and the small chips of the organic material. When the prosthetic filler is used
for a living body, it is added with water, and then they are kneaded to become
a paste state. Thus obtained paste state prosthetic filler is injected into a bone
defect site or the like to restore it.
