Abstract :

This work aimed at manufacturing and characterizing of titanium scaffolds which is coated with Akermanite for using in bone tissue engineering. In order to creating titanium scaffolds, the primary titanium powder was prepared with spacer particle elements (sodium chloride). Akermanite coating was prepared through sol-gel method and applied on the scaffold. The prepared structure was evaluated using scanning electron microscopy (SEM). Coated scaffolds were evaluated after heat treatment by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). In terms of assessing the bioactivity of titanium scaffolds, the samples were immersed in simulated body fluid (SBF). Scanning electron microscopy images of the uncoated and coated titanium scaffolds was prepared after 3,7,14 and 21 days immersing in simulated body fluid (SBF); X-Ray Diffraction analysis (XRD) confirmed the peaks of Akermanite phase in coated samples. According to the results, our study showed that coating of Akermanite on Ti scaffold can increase the bioactivity of titanium scaffolds. The final conclusion of this study confirmed that titanium scaffolds coating with Akermanite will be a suitable and useful choice in bone tissue engineering.
