The influences of accelerated aging on mechanical properties of veneering ceramics used for zirconia restorations
This study evaluated the influences of accelerated aging on the mechanical properties of veneering ceramics used for zirconia frameworks. Five different veneering ceramics for zirconia frameworks were used. Twenty specimens were fabricated for each veneering ceramic. All specimens were divided into...

description | This study evaluated the influences of accelerated aging on the mechanical properties of veneering ceramics used for zirconia frameworks. Five different veneering ceramics for zirconia frameworks were used. Twenty specimens were fabricated for each veneering ceramic. All specimens were divided into two groups. One was subjected to accelerated aging and the other was used as a control. Accelerated aging was performed in distilled water for 5 h at 200ºC and 2 atm. The density, open porosity, surface roughness, three-point flexural strength, and Vickers hardness were measured. The results showed that the density, open porosity, and surface roughness of all examined veneering ceramics were changed by the accelerated aging process. Accelerated aging was also found to have a positive effect on strength and a negative effect on the hardness. |
