Synthesis of bone cement from a natural mineral for biomedical industry

Abstract

Study carried to find out chemical and structural suitability of newly synthesized Eppawala Hydroxyapatite composite as bone cement, by comparing and contrasting it with human bone as well as commercially available bone cement, which is currently used in orthopedic surgeries. Therefore, a mixture of commercially available bone cement and its liquid monomer, commercially available Methyl Methacrylate (MMA) and a mixture of Solid State synthesized Eppawala Hydroxyapatite powder with commercially available MMA were prepared as the direct substitution for bone cement. Then 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 product and human bone while credenting high thermal stability, good crystalline, and porous properties than the commercial product. Finally, study concluded newly synthesized composite can be applied directly as a substitution for commercial bone cement.
