Resumen
Las restauraciones parciales indirectas son usadas frecuentemente para el recubrimiento de dientes severamente comprometidos estructuralmente, permitiendo un menor desgaste a comparación de una corona convencional y manteniendo la mimetización de los tejidos gracias a cerámicas vítreas como el disilicato de litio. El objetivo del presente estudio es analizar el comportamiento del disilicato de litio en restauraciones indirectas en dientes posteriores comprometidos estructuralmente. Debe señalarse que la metodología utilizada fue de carácter cualitativo y documental, cuyo método fue deductivo-inductivo, ya que la bibliografía científica utilizada proporciono todo el campo conceptual de definiciones, clasificaciones y comparaciones acerca del tema a tratar. En el análisis se muestra como resultado: el disilicato de litio es una cerámica de excelentes propiedades mecánicas y ópticas para dientes posteriores con perdida estructural con una tasa de supervivencia de 97,4% a los 5 años. Concluyendo que las cerámicas de disilicato de litio de nueva generación como IPS e.max CAD e IPS e.max press son excelentes con la única diferencia que los sistemas asistidos por ordenador son confeccionados con mayor rapidez, haciéndolos una opción más viable para su elaboración.
Indirect partial restorations are frequently used for the veneering of severely structurally compromised teeth, allowing less wear compared to a conventional crown and maintaining tissue mimicry thanks to glass ceramics such as lithium disilicate. The aim of the present study is to analyze the behavior of lithium disilicate in indirect restorations in structurally compromised posterior teeth. It should be pointed out that the methodology used was of a qualitative and documentary nature, whose method was deductive-inductive, since the scientific bibliography used provided the whole conceptual field of definitions, classifications and comparisons on the subject to be dealt with. The analysis shows as a result: lithium disilicate is a ceramic with excellent mechanical and optical properties for posterior teeth with structural loss with a survival rate of 97.4% at 5 years. The conclusion is that the new generation of lithium disilicate ceramics such as IPS e.max CAD and IPS e.max press are excellent with the only difference being that the computer-aided systems are faster to fabricate, making them a more viable option for fabrication
