Comparison of Mechanical Properties of Aged All-Ceramic Materials

Background: Our research aimed to compare the biaxial flexural strength of glass ceramic and two different monolithic zirconias after aging, examine fracture surfaces with scanning electron microscopy (SEM) perform elemental analysis energy dispersive spectroscopy (EDS). Methods: Two types CAD/CAM materials (Katana UTML Prettau Anterior) a lithium disilicate material (IPS emax Press) were selected for this study. All samples aged thermal cycle 10000 cycles. The disc specimens was determined using three-ball piston test universal testing machine. Biaxial strengths compared each group (n = 10). fractured examined by SEM analyzes performed EDS. Data analyzed 1-way ANOVA Tukey post hoc (p<0.05). Results: Anterior showed statistically significant difference between other groups Following (1141.81 MPa), IPS Emax Press (278.86 MPa) Katana (216.14 strength, respectively. Conclusion: Compared evaluated, had much higher strength. show similar over long term. It is seen that chemical structure has an effect on mechanical capacity.
