| Outline of Final Research Achievements |
Alumina sandblasting treatment is considered to be effective as a pretreatment of the prosthesis. However, it is reported that alumina sandblasting treatment causes deformation of the peripheral portion of the dental crown prosthetic device because it removes contaminants with physical force. Due to deformation, the compliance state of the dental prosthesis becomes worse and the risk of secondary caries and elution of cement is concerned.
By using low temperature atmospheric pressure plasma treatment for various dental materials (dental metal, dental ceramic, zirconia, resin block for CAD / CAM, fiber post), it is equivalent to alumina sandblasting treatment without damaging the material Or higher than that of the other materials.
