Description:
The aim of this paper is the residual stress evaluation in dental implants and the improvementof adherence at the metal-ceramic interface. This study is focused on the development of a multi-layersystem model of Hydroxyapatite/TiO2/Ti components. Our aim is to validate new methods of laserablation deposition and sol-gel, by controlling the residual stresses and actual adherence to titaniumsubstrates. We present a report of the growth of hydroxyapatite layers by PLD (pulsed laser deposition)and sol-gel deposition, and the measurement of their residual stresses.
