POROUS COMPLEX AND BONE REGENERATION MATERIAL |
(57) [Problem to be Solved] To provide a porous composite that has excellent uniform dispersibility
of OCP and that comprises OCP and collagen in a sufficiently mixed state; and a bone
regeneration material comprising the porous composite. [Means for Solution] A porous
composite comprising octacalcium phosphate and collagen, characterized in that in
an image obtained by enlarging a 5.0-mm × 5.0-mm range of a plane of the porous composite
15 times with a scanning electron microscope (SEM), agglomerated particles of octacalcium
phosphate have a fractal dimension (D) of 0.70 or more; and the area of c) portions
consisting of collagen accounts for 5% or less of the total area of a) portions consisting
of agglomerated particles of octacalcium phosphate, b) portions consisting of octacalcium
phosphate microparticles and collagen, and the c) portions consisting of collagen.
