Abstract

The prospect of clinical applications of bio-cements in bone implantation and tissue substitution implies strict requirements as regards material reliability and robustness. We suggest a technique to enhance the mechanical properties of bio-cements based on a-Ca3(PO4)2. Various types of mechanical testing, including compressive deformation analysis, proved that the most robust bio-cement might be fabricated of a-TCP and 1% chitosan. The kinetics of transformation in experiments was considered in order to define the best selection of substance ratios and terms of stabilization. It is essential to increase the ultimate strength and other properties so that they are close to those of cortical bone and this was achieved with the additives chitosan and hydroxyapatite nanoparticles.
