Physical Characteristics for Biocomposite Material Using to Jawbones Compensation

Abstract

Abstract The biocomposite material prepared from polymeric blend (bone cement) as a matrix, and hydroxyapatite powder as a reinforcement material to jawbones compensation is a material that has a good compatibility in terms of physical properties with oral environment in general, and jawbones in particular. The physical properties such as density, water absorption, and thermal properties were tested according to the weight fraction for the reinforcement material. It was found that the density of biocomposite material does not uniformly changed, and it decreases with increasing the ratio of hydroxyapatite particles. While, the water absorption increases with increasing the weight fraction of hydroxyapatite particles. Also, the thermal properties were measured. It was found that the thermal conductivity and the thermal diffusivity of the prepared material were decreased with increasing the weight fraction of hydroxyapatite particles, and therefore the specific heat of the prepared material was also increased due to the porous nature for reinforcement material (hydroxyapatite powder) that enhances the formation of voids between the resulting material.
