At the present time, to speak about aesthetic restorations implies speaking about alloy free ceramics. This field has experienced important changes and revolutionary contributions. This has led to the introduction of a multitude of all-ceramic systems. All of these quest for a balance between the aesthetic, biological, mechanical and functional factors. However, considerable differences exist among them. Therefore, to select the most suitable ceramic in every case, it is necessary to know the main features of these materials and the laboratory procedures. Porcelain selection should not be left up to the laboratory technician. Material selection should be the responsibility of the clinician because he knows and controls the variables that determine the long-term success of the restoration. This article reviews the all-ceramic systems now available and its clinical performance. Lastly, decision making guidelines for the clinician are detailed.

Palavras-chave : Ceramics; chemical composition; laboratory procedure; fracture strength; marginal fit; aesthetics and clinical survival.
