In work by Estrin, et al. [38] it is also shown that nanostructuring of
titanium leads to increase of adhesion and proliferation of bone cells in
comparison to conventional CG titanium. h e authors explain this fact by
surface topography change at a nano-scale. At the same time the inl uence
of nanotitanium surface characteristics -relief topography, chemical state
