| Research Abstract |
Metal is currently widely used in dentistry, but it has an aesthetic disadvantage because of its color. For the purpose of whitening of dental metal, titania film were prepared on a pure titanium, a dental gold alloy, and a pure platium, by applying a microwave plasma CVD (Chemical Vapor Deposition) deposition technique.
Titania film produced was a rutile type at any metal. Some differences were observed in the film forming conditions, the films color on the pure titanium and the pure platinum were white to grayish white. Under the influence of the silver component, the films color on the gold alloy were grayish white. In all of the samples, the adhesive strengths were not enough. The future tasks are to examine the conditions for obtaining the good adhesive strength.
