“…Besides, it was reported that there was no statistically significant difference between the bond strengths between the veneering ceramic and the zirconia core, which were obtained from the knife-edge chisel, notch-rod, and wire-loop rods. 49 Geometrically shaped specimens and in vitro conditions could not fully imitate the oral conditions in this study; however, it was still necessary to enable the SBS test. In vitro testing used in this study may not accurately replicate the clinical failures; therefore this should be taken into account when considering the results.…”

“…22 The connection mechanism between zirconia and veneer ceramic is still not fully clarified. Inokoshi et al 49 reported minor elemental transition at the bonding interface, but it was determined that it was not sufficient to draw definitive conclusions regarding the potential chemical interaction of the veneering ceramic with zirconia. Therefore, micromechanical bonding, surface energy, wetting ability, and TEC compatibility come to the fore in the appropriate bonding between zirconia and veneer ceramics.…”

“…Although the SBS test has been criticized for causing a nonuniform stress distribution at the bonding interface, 48 it remains the most widespread method for evaluating the bond strength of the veneer ceramic to the zirconia core. 6,10,12,[14][15][16]34,35,37 Despite the fact that the "macro" shear testing increases the probability of cohesive failure, 48,49 many studies that investigated the bonding strength of the veneer ceramic to the zirconia core used the "macro" shear test similar to this study. 6,10,15,16,25,31,34,35,37,50 The reason for not using micro shear specimens might be the difficulty of the condensation of veneer ceramic slurry on zirconia in a small area.…”

This in vitro study evaluated the effect of nonthermal plasma (NTP) treatment on the surface roughness (Ra) of the zirconia and the shear bond strength (SBS) between the veneer ceramic and the zirconia. Ninety zirconia specimens were divided into six groups according to the surface treatments applied: control with no treatment; sandblasting with 50‐μm Al2O3 particles; oxygen plasma treated for 5 min; oxygen plasma treated for 10 min; argon plasma treated for 5 min; and argon plasma treated for 10 min. Ra values were measured using a profilometer. Specimens (n = 12) were then veneered with a nano‐fluorapatite ceramic, and the SBS test was performed. Scanning electron microscopy, atomic force microscopy, and X‐ray diffraction analyses were performed. The sandblasting procedure significantly increased the surface roughness; however, the plasma groups showed similar Ra values compared to the control group. NTP and sandblasting treatment significantly increased the bond strength and led to higher SBS values than the control. Plasma application did not induce phase transformation; however, sandblasting caused monoclinic phase transformation of the zirconia. NTP application (either oxygen or argon) can enhance the bond strength between the veneer ceramic and the zirconia core without altering the surface morphology or causing zirconia phase transformation.

Effect of Resin Cement at Different Thicknesses on the Fatigue Shear Bond Strength to Leucite Ceramic

et al. 2022

View full text Add to dashboard Cite

Objectives This in vitro study was performed to evaluate fatigue survival by shear test in the union of leucite-reinforced feldspathic ceramic using different cement thicknesses. Materials and Methods Leucite-reinforced glass ceramics blocks were sectioned in 2-mm thick slices where resin cylinders were cemented. The samples were distributed in two experimental groups (n = 20) according to the cement thickness (60 and 300 μm). The specimens of each group were submitted to the stepwise fatigue test in the mechanical cycling machine under shear stress state, with a frequency of 2 Hz, a step-size of 0.16 bar, starting with a load of 31 N (1.0 bar) and a lifetime of 20,000 cycles at each load step. Results The samples were analyzed in a stereomicroscope and scanning electron microscopy to determine the failure type. There is no significant difference between the mean values of shear bond strength according to both groups. Log-rank (p = 0.925) and Wilcoxon (p = 0.520) tests revealed a similar survival probability in both cement layer thicknesses according to the confidence interval (95%). The fracture analysis showed that the mixed failure was the most common failure type in the 300-μm thickness group (80%), while adhesive failure was predominant in the 60-μm thickness group (67%). The different cement thicknesses did not influence the leucite ceramic bonding in fatigue shear testing; however, the thicker cement layer increased the predominance of the ceramic material failure. Conclusion The resin cement thicknesses bonded to leucite ceramic did not influence the long-term interfacial shear bond strength, although thicker cement layer increased the ceramic material cohesive failure. Regardless the cement layer thickness, the shear bond strength lifetime decreases under fatigue.
