Bonding of dental porcelain to ceramic-metal alloys.
The bond strength of porcelain to the four gold alloys and the three nonprecious alloys was tested with a simplified pull test method, having wide test surfaces. The tests showed that all gold alloys tested were suitable for fusing porcelain. The bond strength in nonprecious alloys was somewhat lower and the location of the fracture lines was more variable. It seems that nonprecious alloys are more sensitive to laboratory procedures. The bond strength and the location of the fracture line had a good correlation in all metal alloys.
