Titanium alloys are widely used in dental implants in virtue of clinical evidences of the excellent biocompatibility performance shown by this alloys. However, there are still a number of unanswered questions regarding the ideal physicochemical properties of titanium surfaces used in dental implants aiming at an appropriate integration with the bone. Furthermore, in the literature there are not still available standards defining superficial properties of dental implants. These characteristics are a fundamental importance since biocompatibility is strongly depended upon the connections between host cells and the titanium surface implant. The present work has as objective the analysis of three processes use for surface treatments of dental implants based on titanium of commercial purity, namely mechanically- induced erosion, chemical etching and the combination of both. Such methods applied to titanium cylinders, have permitted one to estimate more closely their physical and chemical surfaces properties, such as surface morphology, surface topology and contact angle (wet ability). It is also identified the factors and methods allowing to obtain the optimal surface conditions for this purpose.
