Abstract
The main property of calcium phosphate ceramics (CaP ceramics) is to be gradually substituted by newly formed bone or at least to be coalescent with the host bone. In cortical bone in dogs three kinds of porosity were tested (from 100 to 600 microns). The results demonstrate that the macropores up to 100 microns are efficient for the bone ingrowth, however during the first months of implantation larger macropore sizes are more suitable for bone ingrowth.
