Characterization of Biphasic Calcium Phosphate with Ratio of 70/30 Before and After Implanted into Sheep’s Bone
MetadataShow full item record
Nowadays, biphasic calcium phosphate is used for biomaterial to cure bone damage. This study focuses only on mixing ratio of 70% mass of hydroxyapatite and 30% mass of tricalcium phosphate with chitosan and acetic acid as the hardening. Pure HA had done by wet precipitation in sintering process at temperature of 900 oC while β-TCP is at temperature of 1000 oC. Mechanical method of BCP is proven to be a non toxic material and could absorb by the mineral body. Implanted BCP was characterized with XRD, FTIR, SEM-EDS and bone characterization with Vickers Hardness. In XRD analysis, the result is adding chitosan makes BCP less accuracy of pure HA and β-TCP. FTIR shows composition of BCP sample with HA, TCP, H2O, AKB, and N-H bending. SEMEDS releases ratio Ca/P of implant in post operation has irregularity caused by interaction with bone that supported by Vickers Hardness number. HV for 1 month of post operation have larger number for both implanted and control bone.
