A Brief Review on Biomedical Applications of Hydroxyapatite Use as Fillers in Polymer

Abstract

Preparation of hydroxyapatite (HA) through natural sources, such as fish scales or synthetic HA produced from the chemical reaction has been widely used as biomedical materials because HA is bioactive, non-toxic and osteoconductive with a crystallographic structure almost similar to that of the bone mineral. In addition, HAwith particle size < 10 microns is classified as common inorganic filler used to improve the mechanical properties and biocompatibility of polymer composites. The purpose of this review is to collect information related to HA, and to provide readers with information about synthesis methods, advantages of hydroxyapatite as biomaterial,biomedical applications of polymer/HA composites.
