Abstract
L'invention concerne des couches composites de phosphate de calcium bioactives déposées électrochimiquement sur des implants osseux. De tels implants sont implantés sans ciment et se caractérisent par un pouvoir d'ostéointégration amélioré. Lesdites couches composites ultra-poreuses destinées à des implants sont composées d'au moins deux phases de phosphate de calcium de solubilités différentes. La structure ultra-poreuse de ces couches permet de simplifier l'immobilisation de cellules à partir desquelles le tissu osseux peut se régénérer. Les solubilités différentes des composantes de couches individuelles permettent d'obtenir la concentration locale d'ions calcium et d'ions phosphate accélérant le processus de guérison et s'adaptant au processus dans le temps.
