ABSTRACT
<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>The surfaces of the titanium and titanium alloy groups exhibited higher adhesion and proliferation of osteoblasts than those of the mechanical group. The titanium surface was covered with a group of cells, a large number of filopodia, and functional particles. The ALP activity of the titanium group was significantly higher than that of the titanium alloy and mechanical groups.</p><p><b>CONCLUSION</b>EE method in pure titanium and titanium alloy surfaces result in bowl-like nests and nanostructures of different diameters and depths. The diameters of the pure titanium and titanium alloy surfaces range from 30 to 50 μm and 5 to 8 μm, respectively. The former is more conducive to promote the proliferation and differentiation of cells.</p>
