PURPOSE:To enhance biocompatibility and to accelerate the formation of a new bone, in a calcium phosphate porous body having a three-dimensional reticulate structure provided with communicating void channels capable of permitting osteoblasts to penetrate through the porous body up to the central part thereof, by providing pores having a specific pore size to the skeletal of the porous body and setting the porosity to a specific ratio with respect to the void channels and the total voids of the pores. CONSTITUTION:Pores 3 having a pore size of 0.5mum or less are provided to a porous body skeletal 1 and the osteoblasts penetrating in void channels 2 also penetrate through the pores 3 and excellent biocompatibility not developed heretofore and the rapid formation of a new bone can be expected. The porosity of the pores is set to 5-50% of the void channels and the total voids of the pores. The total porosity of the void channels and the pores is pref. set to 40-97%. |
