Abstract

Metal is currently widely used in dentistry, but it has an aesthetic disadvantage because of its color. In this study, TiO2 films were prepared on titanium used as a dental metal by microwave plasma CVD for use as whiteners. The effects of microwave power (PM) and deposition pressure (Ptot) on the adhesion strength and color of TiO2 coating were investigated. The results suggest that a higher deposition pressure and a stronger microwave power are necessary to conceal the color of titanium and to achieve a white color, while a lower deposition pressure and a weaker microwave power are necessary to obtain good adhesion.
