| Abstract Objectives: The purpose of this study was to investigate the curing method-dependent bond strength of resin cement to high translucent monolithic zirconia and lithium disilicate glass ceramic. Methods: Two ceramic materials were used in this study: high translucent zirconia (HTZ) from DD BioZx2 A3-HT and lithium di-silicate (IPS e-max CAD LT A3, C14). Based on the kind of ceramic utilized, forty ceramic discs (10 x 12 mm) were built and categorized into two groups (20 discs each). Each group was then further divided into two subgroups (10 discs each) based on the curing process (dual-cured and light-cured). Following their bonding to a resin cement cylinder of 5 mm in diameter and 2 mm in height, all samples were subjected to micro-shear bond strength test (µSBS). Results: There was no statistically significant difference between the light-cured and dual-cured groupings, in the E-max group (P=0.785). As for the zirconia subgroups, there was no statistically significant difference between light-cured and dual-cured subgroups (P=0.057). There was a statistically significant difference between the two materials' samples, with the E-max samples demonstrated a higher bond strength in both the light and dual-cured subgroups (p=0.001). Conclusions: There is no difference in light-curing nor dual-curing regarding the micro-shear bond strength of E-max or zirconia. E-max has higher bond strength in both modes of curing than zirconia. | ||
