Mechanical Properties of Y-TZP Ceramic after Different Surface Treatments

Abstract:

The objective of this study was to investigate the mechanical properties of yttrium- stabilized tetragonal zirconia (Y-TZP) ceramics after different surface treatments. Cercon Smart Ceramics samples were divided into groups: (1) bland control (no treatment), (2) hand grinding, (3) Al₂O₃ air-abration, (4) irradiation with 200mJ Er:YAG laser. Tensile bond strength, shear bond strength and flexural strength were evaluated after 24h storage at 37°C. Each group had 10 samples for different test. Data were evaluated using ANOVA analysis (α=0.05). Laser and air-abration achieved higher tensile and shear bond strength when air-abration presented the best flexural strength. Surface modifications significantly increased the mechanical properties of the Y-TZP ceramics.
