| Research Abstract |
4META/MMA-TBB resin and calcium carbonate or TCP were made composition, and elution of Ca2+ was measured. Ca2+ elution of all samples increased as the concentration becomes higher. That of beta-TCP had less than alpha-TCP and calcium carbonate. 4META/MMA-TBB resin containing alpha-TCP can facilitate direct contact between the resin and newly formed born. The hybrid layer with the bone marrow was formed on the resin surface when resin was cured in bone marrow, and the rate of bone-resin contact improved. BMP soaked collagen menbrane-nanohydroxyapatite composition was put on dentin and implanted in a femoral musle. Then a high percentage of hard tissue formation to the dentin surface was provided. 4META/MMA-TBB resin containing alpha-TCP was adhered on root surface, and BMP soaked collagen menbrane-nanohydroxyapatite composition was put on the resin. The hard tissue formation was observed on the resin.
