Compressive Fatigue and Wear Properties of Castable Ceramics in Pedodontics

Abstract

Ceramic materials are widely used for restoration of the permanent dentition because of their biocompatibility and aesthetics. I evaluated whether castable ceramics could be applied in clinical pedodontic practice. Wear tests were used to compare several restorative materials, including castable ceramics, and deciduous teeth. Compressive fatigue tests were carried out to evaluate the effect of repeated compressive loads.
I found that the wear volume of castable ceramics was closer to that of deciduous teeth than the other materials. The compressive fatigue strength of castable ceramics was greater than the maximum occlusal force children could produce even after 1,000,000 repeated compressive loads
