Ti and some of its alloys (e.g. Ti–6Al–4V alloy) have become the metals of choice for the endosseous parts of presently available dental implants. In the present study, Ti-Ta-Ag alloys with a different Ag content were prepared using vacuum sintering (VS) and spark plasma sintering (SPS) process. The microstructure and mechanical properties of the Ti-Ta-Ag alloys were investigated. The results show that dense Ti-Ta-Ag alloys prepared using the SPS process exhibit high hardness and a suitable elastic modulus for implant materials for load-bearing applications. The effect of preparation methods on the microstructure of Ti-Ta-Ag alloys is discussed.
