Biocompatibility of materials is a complex concept that takes into account all processes occurring at the interaction between biomaterial and a living organism and is assessed by determining the material behaviour to changes in pH, the application of force, or the effects of degradation of the biological fluids. The oral environment is highly aggressive chemically. In this environment, dental materials can dissolve, can release products by processes of diffusion, can Erode due to the presence of acidic substances, can change colour, or corrode. The paper presents results of experimental research on the assessment of corrosion resistance of a titanium alloy, the Ti10Zr alloy, intended for making dental implants. In developing the alloy was taken into account, on the one hand elimination of chemical composition considered harmful elements such as aluminium, vanadium, etc., on the other hand increased resistance to fatigue in corrosive environments with additions of zirconium. In conclusion we aimed to improve the biocompatibility of dental implant alloy and sustainability. Evaluation of corrosion behaviour of the alloy by electrochemical measurements in environments simulating oral environment showed that regardless of the electrolyte used (four artificial saliva solution) at values higher than 250mV and corrosion current values very close there is a passivation with very close values of corrosion which shows that the alloy forms on its surface a protective and adherent oxide layer.
