摘要：

This study evaluated the effect of air abrasion before and after sintering with different particle type, shape, and size on the surface morphology, monoclinic phase transformation, and bond strength between resin cement and zirconia surface using primer containing silane and MDP. Airborne particle abrasion (APA) was performed on zirconia before and after sintering with different particle shape and size (50 mu m Al2O3 and 25 mu m silica powder). 120 square shaped presintered zirconia samples (Amann Girrbach) were prepared (3 mm height x 10 mm width x 10 mm length) and polished with grit papers #800, 1000, 1200, 1500, and 2000. Samples were divided into 6 groups according to surface treatment-group A: (control) no surface treatment; group B: APA 50 mu m Al2O3 before sintering (BS); group C: APA 50 mu m Al2O3 after sintering (AS); group D: APA25 mu m silica powder (BS); group E: APA25 mu m silica powder (AS) at a pressure of 3.5 bar; and group F: APA 25 mu m silica powder (AS) at a pressure of 4 bar. Samples were analyzed using XRD, AFM, and SEM. The samples were submitted to shear bond strength (SBS) test. A dual cure resin cement (RelyX Ultimate) and primer (Scotchbond Universal) were used. Data were analyzed with ANOVA and Tukey test (alpha >= 0.05). APA in group B significantly increased the surface roughness when compared to all other groups. A significant monoclinic phase transformation (t-m) value was observed in groups C and F and a reverse transformation occurred in presintered groups. The SBS value of group A was 11.58 +/- 1.43 and the highest significant shear bond strength value was for groups B (15.86 +/- 1.92) and C (17.59 +/- 2.21 MPa) with no significant difference between them. Conclusions. The use of APA 50 mu m Al2O3 before sintering and the application of primer containing MDP seem to be valuable methods for durable bonding with zirconia. The use of APA 50 mu m Al2O3 after sintering induced the highest (t-m) phase transformation.
