Determinacion de la bioactividad y la resistencia a la compresion de bloques de Poliapatita Determination of the bioactivity and the compression resistance of Poliapatita

Poliapatita® is a composite in study formed by HAP-200®, CaCO3 and POVIAc®. The aims of this work were the determination of the bioactivity and the compression resistance (CR) of biomaterial. The composite was put in contact with a Simulated Body Fluid (28 days at 37 ºC) to evaluate the formation of an superficial apatite layer similar to the bone mineral composition; and to see how diminished the CR in conditions similar to implantation. The bioactivity was evaluated mainly by Scanning Electron Microscopy, Energy-dispersive X-ray Spectroscopy. The composite studied was bioactive and fulfills the requierement of CR asked by ISO 13779-1:2001.
