summary The aim of this study was to evaluate the shear bond strength of different commercial composite resin cement systems to lithium disilicate all‐ceramic substrate. Five adhesive resin cement systems Panavia 21 and Panavia F (Kuraray), Variolink 2 (Ivoclar‐Vivadent), RelyX Unicem Applicap and RelyX ARC (3M ESPE) were used on all‐ceramic (IPS Empress 2; Ivoclar‐Vivadent) substrate. Shear bond strength of adhesive resin cement to substrate was tested after thermocycling, or without thermocycling ( n = 10). Substrate surfaces of the specimen after loading were SEM microscopically examined. The highest bond strengths in water stored conditions were obtained with RelyX ARC (28·7 ±3·9 MPa), while in thermocycled conditions the highest bonding values were obtained with Variolink 2 (23·2 ± 7·5 MPa). The lowest values in both water stored (5·8 ± 4·0 MPa) and thermocycled (2·4 ± 2·9 MPa) conditions were obtained with Panavia 21. Shear bond strengths appeared to be affected significantly by thermocycling ( anova , P < 0·05). It was concluded that there were significant differences between the bond strengths of adhesive resin cements to lithium disilicate substrate.
