Abstract

See full text

The present invention relates to a surface treatment method for dental zirconia, including sandblasting the surface of three types of dental zirconia (3Y-TZP, 4Y-PSZ and 5Y-PSZ) with alumina particles, and this method optimizes sandblasting conditions for each type of zirconia and enhances mechanical properties by strengthening residual stress. In addition, a dental article including dental zirconia made by the surface treatment method for zirconia, and suitable protocols for the durable bond between resin cements and high-translucent zirconia are suggested.
