Current research focuses on improving the mechanical perfor-
mance and biocompatibility of metal/alloy-based systems through
variations in alloy composition, microstructure, and surface
treatment [24, 27, 28, 34, 38, 47, 56]. In the case of titanium,
signiicant efforts go into enhancing the strength characteristics of
commercial purity grades in order to avoid potential biotoxicity of
alloying elements, especially in dental implants [2, 4, 5, 17, 33].
To enhance the physicochemical and mechanical performance
of implant materials through microstructure control, the top-down
approaches known as mechanical alloying (see Chapters 6, 7, 8, and
9) and severe plastic deformation (SPD) techniques were applied.
Recent studies clearly proved that nanostructuring of titanium can
considerably improve not only the mechanical properties, but also
the biocompatibility [17, 27, 28, 34, 38, 40, 48, 50−54]. On the other
hand, this approach also has the beneit of enhancing the biological
response of the cp titanium surface [27, 28, 40, 53].
