The studies were designed to compare the biaxial flexural test ( BFT ) and 3‐point bending test (3 PBT ) of two kinds of veneering ceramics for zirconia framework, and then to measure the open porosity of the veneering ceramics by A rchimedes method and to characterize their micro‐structures using secondary electron imaging under scan electric microscope ( SEM ). Flexural strength of IPS Z irpress veneering ceramic was significantly higher than IPS e.max C eram ( IPSC ), no significant difference was found between BFT and 3 PBT when used to investigate the same type of veneering ceramic. SEM indicated that the open porosity of IPS e.max C eram is higher than IPS Z irpress.
