Abstract
The aim of this paper is to prepare biopolymer composite material used to compensate for the jaws bones, where the characteristics of poly(methyl methacrylate) resin were developed by addition hydroxyapatite powder as a reinforcement material and studying the effect of selected weight fractures (1,2,3,4,5,6,7,8,9, and 10) wt.% to the polymeric blend (bone cement) on the tensile strength, maximum stress, modulus of elasticity and elongation percentage at break, and before that microstructure analysis was studied by using scanning electron microscope (SEM). the strength results are consistent with the (SEM) images that illustrated significantly increased agglomerates with increasing amount of hydroxyapatite powder. The results showed that the values of these properties increase at specific percentages of hydroxyapatite powder, while decreasing with increasing these percentages to a certain limit. The highest tensile strength value, elastic modulus and best elongation percentage at break were found in composite samples (45.159 MPa at 3%, 2.7365 GPa at 3%, 1.187 mm at 6%) respectively.
