Abstract

Background and Aim: Cementation is one of the most critical steps of the porcelain restoration technique. However, limited information is available concerning the bond strength of current CERAMIC bonding systems. The aim of this study was to evaluate the shear bond strength of three dual-cure RESIN CEMENTs to IPS-Empress2 CERAMICs. Materials and Methods: In this experimental study, 30 pairs of IPS-Empress 2 CERAMIC discs were fabricated with 10 and 8 mm diameters and 2.5 mm thickness. After sandblasting and ultrasonic cleaning, the surfaces of all specimens were etched with 9% hydrofluoric acid for 60 seconds. Then, the three groups of 10 bonded specimens were prepared CERAMIC bonding resin systems including Panavia F2, Variolink II and Rely X ARC. After storage in 37±1o c water for 24 hours and thermocycling in 5o c and 55o c water for 500 cycles with 1-minute dwell time, the shear bond strengths were determined using Instron machine at speed of 0.5mm/min. Data were analyzed by One Way ANOVA test. For multiple paired comparisons, the Tukey HSD method was used. The mode of failure was evaluated by scanning electro microscope (SEM). P<0.05 was considered as the limit of significance. Result: Significant differences were found between different cement types (P<0.05). Variolink II provided the highest bonding values with IPS-Empress2. A combination of different modes of failure was observed. Conclusion: Based on the results of this study, according to the highest mode of cohesive failure, Variolink II seems to have the strongest bond with IPS-Empress2 CERAMICs.
