| 總結: | Anadara granosa (Ag) is a marine bivalve cockles which can be found in the tidal mudflats
bordering the coastal region of many South East Asian countries particularly Malaysia,
Indonesia and Thailand. This research is aim to investigate the potential of Malaysian
cockle (Anadara Granosa) shell to be used as bone substitute material. Therefore, in this
study two types of bioceramic has been produced which were made from pure Anadara
granosa (Ag) powder and mixture of Ag and synthetic Hydroxyapatite (HAP) powder with a
mix ratio of 3:7. Pellets of bioceramic from these powders were fabricated by uniaxial
pressing technique followed by sintering process at different temperatures. Sintering of
HAP-Anadara granosa (HAP-Ag) bioceramic samples at 700°C resulted in highest
compressive strength without the effect of decomposition. The results indicated that the
average apparent density of these samples was 1 .4sg/cm3 and the average compressive
strength was 7.0 MPa. With the compressive strengths comparable to human bone,
HAP-Ag is suggested to be used for injectable bone filler and bone graft for non-load
bearing bone such as cervical and lumbar bone. |
