Document Type and Number:
WIPO Patent Application WO/2012/057252
Kind Code:
A1
Abstract:
The present invention relates to a method for processing a dental porcelain-fused substrate, said method being characterized by irradiating the dental porcelain-fused substrate with ultraviolet rays until the water contact angle of the dental porcelain-fused substrate becomes no greater than 10°, the proportion of the X-ray photoelectron spectroscopy (XPS) strength of carbon atoms among the surface constituent elements becomes no greater than 30%, and the amount of surface charge becomes greater than 0 nC/cm2. By means of the present invention, it is possible to provide: a method for processing the dental porcelain-fused substrate that can increase the adhesiveness of the dental porcelain-fused substrate to porcelain, dental cement, or a dental crown having dental cement therebetween; the dental porcelain-fused substrate; the dental porcelain-fused substrate; a method for producing a dental crown restorative material; a method for processing a dental crown restorative material; and the dental crown restorative material.
