| 1 | Effect of colouring green stage zirconia on the adhesion of veneering ceramics with different thermal expansion coefficients显示文摘This study evaluated the adhesion of zirconia core ceramics with their corresponding veneering ceramics, having different thermal expansion coefficients(TECs), when zirconia ceramics were coloured at green stage. Zirconia blocks(N5240; 6 mm37 mm37 mm) were manufactured from two materials namely, ICE Zirconia(Group 1) and Prettau Zirconia(Group 2). In their green stage, they were randomly divided into two groups. Half of the specimens were coloured with colouring liquid(shade A2). Three different veneering ceramics with different TEC(ICE Ceramic, GC Initial Zr and IPS e.max Ceram) were fired on both coloured and non-coloured zirconia cores. Specimens of high noble alloys(Esteticor Plus) veneered with ceramic(VM 13)(n516) acted as the control group. Core–veneer interface of the specimens were subjected to shear force in the Universal Testing Machine(0.5 mm?min21). Neither the zirconia core material(P50.318) nor colouring(P50.188) significantly affected the results(three-way analysis of variance, Tukey's test). But the results were significantly affected by the veneering ceramic(P50.000). Control group exhibited significantly higher mean bond strength values(45.768) MPa than all other tested groups((27.164.1)2(39.764.7) and(27.465.6)2(35.964.7) MPa with and without colouring, respectively)(P,0.001). While in zirconia–veneer test groups, predominantly mixed type of failures were observed with the veneering ceramic covering,1/3 of the substrate surface, in the metal–ceramic group, veneering ceramic was left adhered.1/3 of the metal surface. Colouring zirconia did not impair adhesion of veneering ceramic, but veneering ceramic had a significant influence on the core–veneer adhesion. Metal–ceramic adhesion was more reliable than all zirconia–veneer ceramics tested. | Guliz Aktas Erdal Sahin Pekka Vallittu Mutlu zcan Lippo Lassila | 2013 | International Journal of Oral Science2013，5，4： | 2 |
