Since Branemark introduced the concept of osseointegration, different implant materials have been evaluated by several studies in vivo and in vitro. Among the materials tested, titanium has been widely used because of its excellent biocompatibility and adequate mechanical properties. Many studies have reported that the cellular and tissue implants are not only affected by their chemical properties, but also by its topography or surface roughness. The aim of this study was to evaluate the influence of surface modification by coverage biomimetic calcium phosphate on the degree of wettability of experimental Ti-30Ta alloy. Therefore, were made 20 discs of Ti-30Ta alloy with 13mm in diameter and 3 mm thick, divided into two groups: untreated (control group) and treated (biomimetic surface treatment). All specimens were taken Goniômetro300-F1(Ramé-HardInst.Co) for reading the contact angle. Results showed mean values of 82.1+0.72 for GI and 11.08+0. 20 for GII. It is concluded that the biomimetic surface treatment allowed higher wettability and lower surface tension to the material
