Abstract
En la actualidad, los pacientes son cada vez más exigentes con los resultados estéticos y desean que no se utilicen subestructuras metálicas en sus restauraciones, lo cual pone de manifiesto la gran importancia de las restauraciones completamente cerámicas. La estética es un concepto subjetivo y cultural en continuo cambio en función de las circunstancias socioculturales del momento y del entorno. Como consecuencia de ello, el desarrollo de la Odontología restauradora en las últimas décadas ha tenido como objetivo conseguir un material con una resistencia a la fractura y al desgaste similar a la de los dientes naturales, presentando además unas propiedades ópticas que permitan reproducir la estética, la forma y el color de la estructura dental, satisfaciendo de esta manera las expectativas de los pacientes. Actualmente, la prótesis fija debe no sólo cumplir unos principios biológicos, mecánicos y funcionales, sino también responder a unas máximas exigencias estéticas. En este sentido, no podemos olvidar que las posibilidades de restauración han estado siempre subordinadas tanto a la habilidad de los operadores, como a los avances tecnológicos en odontología y de los materiales disponibles en el mercado. Las restauraciones metal-cerámicas siguen siendo en la actualidad las más utilizadas en prótesis fija, ya que ofrecen una estética, biomecánica y funcionalidad aceptables, así como una elevada predictibilidad. Son restauraciones que reúnen por un lado la resistencia y precisión de los metales, y por el otro, la estética de las porcelanas...
Currently, patients are more exigent with esthetic results and they do not want metallic substructures in their restorations, this is why the importance of all-ceramic restorations is increasing. Esthetics is a cultural and subjective concept continuously changing according to sociocultural and environmental aspects. Therefore, the development of restorative Dentistry over the last decades has the objective of obtaining a material as resistant to fracture as a natural tooth, as well as to develop optical characteristics similar to the esthetic, form and color of the natural dental structure, satisfying in this way the patients´ expectations. Nowadays, fixed prosthesis should not only fulfill biological, mechanic and functional principles, but also respond to esthetic demands. In this sense, we should not forget that restoration possibilities have always depended on the operators´ abilities and on the technological improvements on dentistry as well as the available materials. Metal-ceramic restorations are the most currently used in fixed prosthesis, due to the fact that they show acceptable esthetic, bio-mechanic and functional results, as well as high predictability. Those restorations combine resistance and accuracy with ceramic aesthetic...
