oxidized surface (Fig. 9.34b), the surface area
of cells attachment is minimized. The H

oxidized surface shows
excellent cell spreading and proliferation (Fig. 9.34c), forming a
three-dimensional ibril network. In the HF treated surface, the
colonization of the cells was noticed, with cells developing a double
net-like layer structure (Fig. 9.34d) [14].
