Abstract

In Malaysia recently, it was found that cockle shell (Anadara granosa) is a potential source of biomaterial for bone repair. It is the most abundant sea species cultured in Malaysia. A possible advantage of using cockle shell as a biomaterial is that they may act as an antilog of calcium carbonate. Malaysian Nuclear Agency took this challenge to develop synthetic bone graft from natural cockle shell. To date, the artificial bone graft substitutes developed from hydroxyapatite (Ca₁₀(PO4)₆(OH)₂) a bio ceramic is similar to the mineral constituent of human bone. The structure and the composition of hydroxyapatite (HA) are similar to the mineral phase of bone and, its bioactivity and biocompatibility makes it a preferred bone graft.
