Summary

Since the introduction of the resin composites on the market marginal leakage causing secondary caries has been one of the major clinical topics. As the composites shrink during hardening they tend to develop a gap between the filling and the tooth, where bacteria can enter. This can be overcome by using bonding techniques, but bonding does not give complete success. An alternative to use shrinking composites could be the use of fully ceramic filling material based on biominerals that harden via a acid base reaction with water. The biomineral technology based on Ca-aluminate has been proven to yield a bond to living tissue and as such the filling material would naturally avoid marginal leakage without the use of any pre-treatment or extra bonding systems. In this paper the influence of thermo cycling on the marginal leakage of a restorative material based on biominerals is evaluated and compared to that of a resin composite.
