[The effects of nanostructured titanium fabricated via surface plastic deformation on Saos-2 cell adherence, proliferation and differentiation].

Purpose: To study the effects of nanostructured titanium fabricated via surface plastic deformation on Saos-2 cell adherence, proliferation and differentiation in vitro.

Methods: Nanostructured titanium surfaces were prepared using plastic deformation and divided into three groups: group I (30 minutes, n=6), group II (60 minutes, n=6) and group III (90 minutes, n=6), according to the time of preparation. The untreated titanium was used as control group.
