项目摘要

Calcium phosphate faom is exerent for bone graft material. Various methods are applicable for the fabrication of porous HAP foam. Among these method, only the foam method is known to permit three-dimensional fully interconnected porous structure similar to cancellous bone. But, it is very difficult to make this foam same as a shape of bone defect using foam method. Small size foam hardened each other after filling to the defect clear this problem. We tried to develop the self setting foam using small size particle of α-TCP foam. This α-TCP foam hardened with NaH_2PO_4 solution or distilled water. Setting time was about 5 hours at room temperature with NaH_2PO_4 solution, and 24hours at 200℃ with distilled water. Chemical product after setting was DCPD with NaH_2PO_4 solution, and HAP with distilled water. After setting, needle like crystals which length was about 20 to 50 μm were formed on the surface of α-TCP foam. Needle like crystals penetrated each other during the setting reaction. This contributed to set in the same mechanism as dental plaster.

磷酸盐FAOM用于骨骼的骨骼，适用于多孔HAP泡沫的易剂量，泡沫方法可允许三维完全相互连接的多孔结构silar silar to to to to骨。使用泡沫。 DCPD用NAH_2PO_4溶液，在设置后用敏锐的水的HAP在α-TCP泡沫的表面上形成了大约20至50。石膏。
