Development of regenerative therapy of cementum to the gap of vertical root fracture and interdigitation to the resin

将4META/MMA-TBB树脂与碳酸钙或TCP组成，测定Ca2+的洗脱量。所有样品的Ca2+洗脱量随着浓度的增加而增加。β - tcp比α - tcp和碳酸钙含量少。含有α - tcp的4META/MMA-TBB树脂可以促进树脂与新成型的树脂直接接触。树脂在骨髓中固化后，在树脂表面形成了与骨髓的杂化层，提高了骨-树脂的接触率。将BMP浸泡的胶原膜-纳米羟基磷灰石组合物置于牙本质上，植入股肌。然后，牙本质表面形成高百分比的硬组织。将含有α - tcp的4META/MMA-TBB树脂粘附在根表面，并将BMP浸泡的胶原膜-纳米羟基磷灰石组合物涂在树脂上。树脂表面有硬组织形成。

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.
