Ti Implant Surface State After Micro-Arc Oxidation Process

In this work the anodic oxidation of the titanium has been applied for its surface biofunctionalization. The surface treatment done in 2M H3PO4 + (0–1)%HF electrolyte in broad 30–240 V potential range results in porous morphology and hydrophilic properties. The anodic oxidation done in Micro-Arc Oxidation (MAO) conditions at 180–240 V, confirmed most attractive surface morphology for implant applications. The HF content support surface morphology changes in direction of biofunctionalization. Detected by XPS contaminations introduced during the process, especially positive in the bone regeneration phosphorus content, confirmed the usefulness of the process in dental implant applications. Finally, in terms of surface treatment, the transition from a laboratory flat surface to a real implant was presented.
