The paper describes β-TCP/DCHA and mineral phase structural bioceramics(CHA) as well astheir 3-D structures, bioactivity, degradability and introducing new bone growth. FT-IR, XRD, SEM andMicro-CT were used to evaluate β-TCP/DCHA and mineral phase structural ceramics before and afterimplantation. Osteoblasts were immersed in the bioceramics and implanted in the rabbit femora. Theexperimental results showed that new bone grown in β-TCP/DCHA, and scaffolds were degraded withnew bone formation and growth. The results indicated that β-TCP/DCHA was a better tissue engineeringmaterial. A kind of biomaterial (β-TCP/CHA) can be used for in situ formation or in vitro individuationformation. The experimental results indicated that β-TCP/CHA possessed better osteoblast affinity.Osteoblasts can adhere, proliferate and grow better on the material. The experiments in vivo showed thematerials bonded with osseous tissue. The implants were degraded obviously after 6 months, and newbone replaced degradation materials
