Abstract

The aim of the paper is the study of adsorption process in simulated artificial saliva after 5 months immersion of implant dental biomaterial. The simulated artificial saliva are Afnor and Tani-Zucchi solutions and implant materials are Ti and Ti-Al- V. Infrared (IR) and Environmental Scanning Electron Microscopy (ESEM) methods were performed in order to identify the structure and composition of the film reformed after immersion in saliva and corrosion process. Despite of good corrosion resistance of Ti and Ti-Al-V alloy which was put in evidence using electrochemical methods [1-3], Ti and Ti-Al-V immersed in simulated medium of Afnor and Tani-Zucchi for longer time noticed small effects of a local corrosion as an intercrystalline type. The IR and ESEM methods confirm the presence of phosphate anion in the solutions as a result of an absorption process and topological changes on the samples surface after immersion in Afnor and Tani-Zucchi media, indicating the presence of Na and Cl elements existing in composition of both artificial saliva..
