Abstract
Provided are a porous composite containing OCP and collagen having higher compressive strength than before: a bone regeneration material containing the same: and a method for producing a porous composite. The porous composite contains octacalcium phosphate and collagen, has a pore size of 5 to 40 μm as determined by measurement using a mercury porosimeter, and contains pores of 71 to 200 μm at a rate of less than or equal to 8% in all pores of less than or equal to 200 μm.
Claims4
A porous composite comprising octacalcium phosphate and collagen, a pore size of 5 to 40 μm as determined by measurement using a mercury porosimeter, and containing pores of 71 to 200 μm at a rate of less than or equal to 8% in all pores of less than or equal to 200 μm.
A method for producing a porous composite comprising octacalcium phosphate and collagen, comprising the step of:
- dipping and freezing a gel, sol or liquid containing octacalcium phosphate and collagen in a liquid refrigerant.
