The effect of ion exchange on the flexural strength of feldspathic porcelains.

The use of ceramic restorative materials is becoming more widely accepted by the dental profession. Concern over the inherent problems related to failure through the propagation of cracks has led to the development of new reinforced ceramics. Ion exchange is a simple, relatively low-temperature process that can have a substantial effect on the flexural strength of feldspathic dental porcelains. This study would support the use of such a material to reinforce dental ceramic restorations.
