| Research Abstract |
Sintered and non-sintered carbonate apatite ceramics with different porosities were prepared and implanted into the skin of dogs to investigate their bioresorbability and also to see if they have an osteoinductive potential or not. At 3 and 6 months postoperatively, the tissues containing materials were subjected to μ-CT analysi before decalcification for light microscopy. Compared to commercially available porous β-TCP, non-sintered CA resorbed to an appreciate extent and in 7 of 16 specimens no CA materials were confirmed. Although not so evident on μ-CT images, newly formed bone was indicated with non-sintered CA ceramics at 6 months.
