Plasma treatment of the titanium surfaces was performed using either a mean plasma jet power of 3 W (c, d) or 5 W (e, f). No surface alterations were detected after plasma treatment of microstructured titanium surfaces. (Magnification: SEM a, c, e: ×10,000). No microbial growth is detectable on Rodac plates after plasma treatment (b, d, f).
