1. INTRODUCTION The present state of knowledge related to implantology, material engineering, biomechanics and physiology allows developing biomaterials meeting our basic expectations. Implants whose working time is expected in excess of 20 years must be continually adapted. The slow rate of degradation of the metal in the human body is unavoidable (infiltration of metal ions into the body) [1÷3]. The implant is affected differently than the bone on the surrounding tissue. Troublesome is also the question of optimizing the osseointegration process. This phenomenon is still not fully understood. Therefore, it is difficult to predict the effect of modifications of the implant surface on the osseointegration process [4, 5]. The anodized layer exhibits the best properties of the modified surface layer on titanium . Anodizing can change the surface properties, such as chemical composition, thickness, microstructure, and surface morphology. It is possible to produce oxides of approx. 1 μm of thickness over the complex shape of the implant. Such possibilities place anodic oxidation before other methods of surface treatment of titanium. In the field of surface treatment of titanium for biomedical purposes, we know what factors affect the effective process of osseointegration . We can evaluate the impact of mechanical action of the implant on the surrounding tissue and then modify its shape in order to minimize the transmitted forces. The acquired clinical hands-on experience of osseointegration allows the use of better materials . The present state of knowledge has contributed to a significant shortening of postoperative healing. Anodic oxidation of titanium and its alloys in the electrolyte containing H3PO4 is well known . Currently no comprehensive research exists on the anodic oxidation of titanium in the electrolyte containing H3PO4 with the addition of HF . The obtained surface oxide didn’t have a sati[...]
