The effect of zirconia thickness and curing time on shear bond strength of dualcure resin cement.


This study evaluated how zirconia thickness affects shear bond strength (SBS) between zirconia and dual-cure resin cement. Eighty specimens (40 blocks of 1 mm thickness zirconia and 20 of each 1.5 and 2 mm) were divided into 8 groups according to zirconia thickness and light-curing time. Group A, B, C, and D were light-polymerized during 20 s and group E, F… (More)
