Biaxial flexural strength was tested according to ISO 6872 with 20 disc form specimens sliced from each block before and after heat treatment. Also, the crystalline structures were observed using field-emission scanning microscopy (FE-SEM, Hitachi) and x-ray diffraction (XRD, Rigaku) analysis. The mean values of the biaxial flexural strength were analyzed by the Mann-Whitney U test at a significance level of p = 0.05.
There were no statistically significant differences in flexural strength between IPS e.max CAD and Rosetta SM either before heat treatment or after heat treatment.
In the practice of esthetic restorative dentistry, clinicians and laboratory technicians work as a team to restore both form and function for their patients. Each member of the restorative team contributes his or her expertise to meeting this goal.
Although working as a team, the dentist and ceramist are seldom able to sit face-to-face to go over the particulars of a case,
