Evaluation of the bonding strength between yttrium-stabilized zirconia and coating ceramics with three-point flexural Test: The surface treatment effect

Abstract: Aim: This study aimed at evaluating with the three-point flexural test, the bonding strength of tetragonal zirconia polycrystalline stabilized by yttria zirkonzahn (Y-TZP) and two coating ceramics (Ice e Vision Zircon), with two surface treatments (treated and untreated). Materials and Methods: Forty Y-TZP bars were divided into four groups (n = 10): vision zircon/without treatment (VZ/woT), vision zircon/with treatment (VZ/wT), ice/without treatment, and ice/with treatment (I/wT). The flexural strength assay was conducted using a 50 N load cell and 1 mm/min speed. Results were analyzed with one-factor ANOVA, two-factor ANOVA, and Tukey’s test (α = 0.05). Results: The treatment surface of Y-TZP affected significantly the bonding strength (P = 0.019), with higher values in VZ/woT group in comparison with the groups VZ/wT (P = 0.027) e I/wT (P = 0.034). The variable “coating ceramic” was not statistically significant (P = 0.138), on the other hand, the variable “surface treatment” significantly decreased the strength values when vision zircon ceramics was used (P = 0.018). Conclusion: This study concluded that the use of the evaluated ceramics did not influence the bond strength and the surface treatment decreased strength depending on the coating ceramics.
