Characterization of duck egg shells and bioceramic materials in making denture applications

Duck egg shells contain higher calcium which potent to be use as materials of denture�bio-ceramic. Denture bioceramics were made from feldspar, quartz, kaolin, and duck egg shells. In this work, characterization and synthesis hydroxyapatite from duck egg shells as bioceramics for the manufacturing of artificial tooth was carry out. X-Ray Diffraction (XRD) was used to analyze the characteristics of hydroxyapatite. Synthesis hydroxyapatite from duck egg shells were produced calcium (Ca) is 99.63%, and CaO is 99.41%. Furthermore, calcination methods were used by XRD. The XRD results at the calcination temperature of 900oC were feldspar CaO content of 96.87%, SiO2 of 1,85%, quartz CaO of 1.58%, SiO2 of 95.47%, and Kaolin CaO of 68.08%. Among of three various samples used, sample of B with compositions of Ca and Si are 62.89, and 26.89, XRD results of eggshell powder produced the largest CaO compound at a burning temperature of 9000C for 1 hour with a hexagonal-shaped compound with a Ca / P ratio of 1.61. respectively has good result. In addition, bioceramics obtained is in accordance to standard manufacturing of denture. Therefore, synthesis hydroxyapatite from Duck egg shells contains very high calcium which is component that potential to be used for Dentures based
bioceramic.
