Preparation of Bioactive β-tricalcium Phosphate Scaffold with Bone-like Structure

摘要

Porous β-TCP scaffold was prepared using three-dimensional gel-lamination technology with foamy slurry. Then the sintered scaffolds were soaked in 1.5SBF solution to achieve scaffolds with bone-like structure. After soaking, a low crystallized bone-like apatite layer containing CO_3~(-2) was formed on the surface of the scaffold. With presoaking in NaOH solution, the formation of the bone-like apatite layer on the surface of the scaffold in 1.5SBF solution was accelerated. In this way, a bioactive porous β-TCP scaffold with bone-like structure could be prepared.
