Comparison between Differently Synthesized Hydroxyapatite Composites for Orthopedic Applications

Abstract

Study carried to find out chemical and structural suitability of newly synthesized Eppawala hydroxyapatite composite varieties as bone cement, by comparing and contrasting them with human bone as well as commercially available bone cement, which is currently used in orthopedic surgeries. Commercially available methyl methacrylate (MMA) monomer used to reinforce solid state sintered and sol gel synthesized hydroxyapatite ceramic to prepare its composites as bone cements and their physical and chemical properties including composition, crystallinity, presence of functional groups, thermal stability, surface morphology, and microstructural features were examined compared to human bone. Results show there is a close similarity between synthesized products and human bone while credenting high thermal stability, good crystalline, and porous properties than the commercial product. Finally, study concluded newly synthesized composites can be applied directly as a substitution for commercial bone cement while having different properties from each other.
