Todas as cerâmicas são iguais?

Abstract

The development of dental ceramics was only possible due to the introduction of new technological resources, that accompanied by the increasing demand for aesthetics generated new concepts about the use and applications of those materials. These circumstances resulted in the need of various types of ceramics and therefore production methods, which aims to deliver different results in terms of strength and translucency. In this context, it is crucial to understand each available ceramic’s system characteristics and limitations, so as to properly select the right material for given clinical application. The objective of this work is to assist the dental surgeon in the choice of an all-ceramic material for restorations in full-coverage crowns, among three of them: feldspathic porcelain, lithium disilicate and dental zirconia. In this work was concluded that the ceramics are not identical and that feldspathic porcelains are often more used for aesthetic cases, especially in the stratified technique, the lithium disilicate combines aesthetics and strength and, finally, the dental zirconia presents itself as a promising material due to its superior mechanical properties.
