Comparación de la resistencia a la flexión entre una matriz de alumina nanométrica reforzada con un material amorfo tipo la2o3.al2o3.3sio2: con un producto dental de oxido de aluminio infiltrado
Abstract
Los sistemas cerámicos han revolucionado los procedimientos de restauración dental debido a su gran estabilidad química, alta resistencia a la flexión y excelente estética. En este trabajo, se compara la resistencia a la flexión de un biomaterial compuesto obtenido mediante la infiltración de un vidrio del sistema (La2O3.Al2O3.3SiO2), en una matriz de alúmina nanométrica, con un material dental comercial del tipo cerámico. La resistencia se evaluó mediante el método ball-ring y el tipo de fractura obtenida fue analizado por SEM. Las diferencias encontradas pueden explicarse por factores como el grado de infiltración de las probetas y la porosidad remanenteDownloads
