Several studies in vitro and in vivo accomplished in dental implants have demonstrated that the chemical and physical properties of biomaterials are able to regulate the initial tecidual response around the implant. This tecidual response depends directly on the hydrophily, roughness, texture and chemical composition of the surface. Plasma treatment can be used to improve the surface properties of commercial pure Ti, in order to create different surface topographies, changes in roughness, and modifications in the surface wettability. In this study a surface modification in titanium Cp degree II was carried out, through the plasma treatment and using argon-ion bombardment. A comparison of surface properties and their influence on the cells behavior was also accomplished, besides the quantification of surface roughness, wettability and cellular proliferation. The results showed that the argon-ion bombardment influences the surface energy value, surface roughness and the surface topography of Ti materials. These parameters influence the cellular proliferation process.
