Abstract:
This study aimed to find out chemical and structural
suitability of 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 that there is a close similarity between
synthesized product and human bone and it has exhibited high
thermal stability, good crystalline and porous properties than the
commercial product. Finally, the study concluded that synthesized
hydroxyapatite composite can be used directly as a substitution for
commercial bone cement.
