Surface texturing of titanium alloys implants have been improved by additive and subtractive modification methods. Recent progress on the highly controlled topographical and chemical properties has been guaranteed by laser ablation technology. The effects of Ti-15Mo textured surfaces (n= 12 surface textures; laser Yb:YAG irradiation) on the adhesion and growth of non-tumorigenic human keratinocytes cell line (HaCaT) were evaluated. It was evaluated the formation of the crystalline phases Ti, Ti6O, Ti3O and TiO2 by the melting and fast cooling processes during irradiation. The resulting phases on the irradiated surface were correlated to the laser beam parameters. The aim of the present work was to control titanium oxides formations by using laser ablation technique. The cytotoxicity response of Ti-15Mo surfaces was evaluated in order to improve implants osseo integration. Thereby the use of laser ablation for post-processing should guarantee a clean, reproducible and controlled surface morphologies.
