Effect of Sandblasting Angle and Distance on Biaxial Flexural Strength of Zirconia-based Ceramics

Abstract

Change in sandblasting angle and distance had no significant effect on the biaxial flexural strength of zirconia-based ceramic, but surface roughness was significantly different in the study groups. Clinical significances: Regardless of sandblasting angle, increasing distance to 25 mm significantly decreases surface roughness that may negatively affect zirconia bond strength.
