[Comparative study of the titanium and titanium alloy implant electrolytic etching surface].

Objective: This preliminary study aims to investigate the effects of titanium and titanium alloy micro-nano-dimensional topography on the biological behavior of osteoblasts in vitro.

Methods: Electrolytic etching (EE) method was used to produce micro-nano dimensional titanium surfaces. The surfaces were observed to determine their effects on the adhesion, proliferation, cell morphology, and alkaline phosphatase (ALP) activity of osteoblasts.
