Abstract:
In this work, the titanium powder was used for preparing highly interconnected porous scaffolds by impregnating polymer method. Subsequently, the electrochemical method and the biomimetic mineralization method were adopted to deposit calcium phosphate coatings on the sintered scaffold which was supposed to improve the scaffold bioactivity. The experimental results show, with the use of the two methods, the scaffolds are successfully covered by the deposition of the nano-net structure calcium phosphate coating, and they hold their three dimensional interconnected porous structures. Therefore, this kind of bioactive composite scaffold with such mechanical strength as that of woven bone should be a promising bone graft in clinical applications.
