Abstract
The purpose of this study was to improve surface wettability on titanium by glow discharge treatment. In our previous study, we observed early cell attachment treated by the experimental device of glow discharge treatment. However, we could not examine the treatment condition of this treatment. Therefore, in this study, we developed the new device of glow discharge treatment to decide the treatment condition of improving surface wettability. In addition, we investigated the protein attachment and sterilization of titanium surfaces prepared by glow discharge treatment. The improving wettability depended hearvily on an electric current of this treatment.Higher level of protein attachment was observed on the surfaces after treatment. Furthermore completely sterilization was observed on the titanium plates with glow discharge treatment. These results suggested glow discharge treatment was useful to obtain excellent biocompatibility for titanium.
