Resistencia a la Fractura; CAD/CAM; Dientes Endodónticamente TratadosResumen
Tradicionalmente, la rehabilitación de los dientes posteriores tratados endodónticamente con gran pérdida de estructura coronaria era con una corona convencional y un poste con núcleo. Con el avance de la adhesión, aparecieron otras alternativas de restauración, como la endocrown que utiliza la cámara pulpar como un medio retentivo macromecánico, conservando así la mayor cantidad de tejido dentario remanente. Además, existe hoy en día una variedad de materiales con la tecnología CAD/CAM cada vez más al alcance del odontólogo. El objetivo es conocer los resultados de estudios in vitro en molares sobre la resistencia a la fractura de endocrown utilizando diferentes materiales CAD/CAM. En la presente revisión narrativa se recopilaron artículos originales de los motores bibliográficos como PubMed, LILACS, SciELO, Scopus y Google Scholar en el periodo 2018-2023. Se concluye que la endocrown de cerámica disilicato de litio obtuvo los promedios más altos de resistencia a la fractura respecto a los otros grupos y que los modos de falla reparable lo obtuvieron la cerámica infiltrada con polímero (PICN) y la resina.
