Outline of Final Research Achievements |
Fully interconnected porous carbonate apatite block was found to be fabricated by fabricating fully interconnected porous precursor or calcium carbonate block. This is due to the three-dimensional compositional transformation through dissolution-precipitation reaction. Regardless of the interconnected porous structure, one, two or three-dimensional porous structure, new bone was formed at the center of the block after implantation for 4 weeks. On the other hand, bone formation nature was different when pore morphology was different even when key interconnected structure was the same. It was demonstrated that optimization of the pore structure is important for improving the capability of carbonate apatite block.
