Effects of surface treatments, LTD aging, and pH on the mechanical behavior of high-translucent zirconia.

ABSTRACT:

Backgrounds

This study aims to evaluate the effects of low-temperature degradation (LTD) aging and pH variations on the mechanical and surface properties of 4Y-TZP and 6Y-TZP high-translucent zirconia materials subjected to different surface treatments.

Methods

A total of 336 Y-TZP specimens (1.2 mm thickness, 12 mm diameter) were prepared and divided into two zirconia groups (4Y-TZP, 6Y-TZP) and four different surface treatment subgroups (glazed, grinding, grinding + polishing, grinding + glazing) (n = 42 per subgroup). Control specimens were stored in distilled water for 28 days (n = 14 per subgroup), while the remaining samples underwent LTD aging in an autoclave for 30 h. After aging, the specimens were immersed in pH 3 (acidic) and pH 9 (basic) solutions for 14 days. Th
