Název v původním jazyce

Study of interactions between bioapatite from human bone and Ca - deficient hydroxyapatite

Popis výsledku v původním jazyce

Bioapatites (A), prepared from natural bones, are used as implants for bone grafts or powder bone fillings. The bioapatites are obviously obtained by calcinations of natural bones. The main advantage of BA from natural bones is the right ration between Ca, P and other minerals. The Ca-deficient hydroxyapatite (CDH) is biocompatible and cheap material very often used in biological and nonbiological applications. The aim of this study is to prepare CDH particles on surface of bioapatites. The bioapatites are prepared by two calcinations temperatures (500 and 700oC, respectively) and subsequently crushed in mortar or milled in jet mill. The Ca-deficient hydroxyapatite is prepared on the surface of bioapatites by easy precipitation route to decrease possible influence of more invasive preparation techniques. The resulting composites of A + CDH were characterised by X-ray powder diffraction (XRD), infrared spectroscopy with Fourier transformation (FTIR) and scanning electron microscopy (SEM). The XRD shows broadening of basal reflection of A in composite, which could confirm presence of CDH. The scanning electron microscopy shows creation of small CDH particles and film-like structure. The interactions between CDH and A are probably by physical and non-bonding base.
