“…4,19 The positive impact of using such materials is well-established in the literature. [20][21][22] With such a plethora of materials and techniques, it is comprehensible that the gold standard for zirconia bonding be still unestablished. This study was performed to evaluate the significance of the SIE technique, as well as the impact of using a MDP containing resin bonding agent on the initial resin bond strength to zirconia ceramics.…”

Objective To evaluate the shear bond strength of resin cements to zirconia treated with the selective infiltration etching technique (SIE). Materials and Methods Forty‐seven zirconia specimens were prepared with a sequence of silicon carbide abrasives, cleaned in an ultrasonic bath. Three samples were separated for atomic force microscope (AFM) analyses (one nontreated for control, one sandblasted, and one selective infiltration etched) and the remaining were randomly distributed in four groups, according to the combination of surface treatment and resin cement: group 1a (sandblasting + Variolink II), group 1b (sandblasting + Panavia SA Plus), group 2a (SIE + Variolink II), group 2b (SIE + Panavia SA Plus). A composite resin cylinder (3 mm × 3 mm) was cemented to the zirconia surface, as per each group's specific protocol. After storing 24 hours in distilled water at 37°C, the specimens were tested for shear bond strength and the results were subjected to statistical analysis. Results At 24 hours, the highest SBS values were observed in group 2b, where the SIE technique was used in conjunction with Panavia SA Plus. Lowest values were found in group 1a. Increased surface roughness was observed with SIE. Conclusions SIE significantly enhanced the resin bond strength to zirconia. However, cement selection was also an important factor, for both surface treatments tested. Clinical Significance Use of SIE method combined with MDP monomer containing resin cement can provide clinically acceptable bond strength between zirconia and resin cement.

“…Each specimen was subjected to shear forces using a testing device (Bisco Shear Bond Tester, Bisco Inc.; Schaumburg, Illinois). A shear force was applied to the interface at a cross‐head speed of 0.5 mm/min until failure . The force at the failure (Newton) was recorded and divided by the surface area (mm 2 ) of the debonded specimen to calculate the SBS in mega pascals (MPa).…”

Objective To evaluate the influence of saliva contamination and cleaning procedures on shear bond strength (SBS) of a self‐adhesive resin cement (SAC) to zirconia surfaces. Materials and Methods A total of 160 sandblasted zirconia blocks were randomly divided into eight groups as follows: No saliva contamination, no cleansing (NC‐NC); contamination with saliva, no cleansing (SC‐NC); no saliva contamination, cleansing with a zirconia primer (ZP; Z‐Bond, Danville Materials, Inc., S. Ramon, California) (NC‐ZP); contamination with saliva, cleansing with ZP (SC‐ZP); no saliva contamination, cleansing with hydrofluoric acid (HF; Ultradent Porcelain Etch; Ultradent Products, South Jordan, Utah) followed by cleansing with ZP (NC‐HF‐ZP); contamination with saliva, cleansing with HF followed by cleansing with ZP (SC‐HF‐ZP); cleansing with ZP, contamination with saliva, cleansing with ZP (ZP‐SC‐ZP); application of ZP, contamination with saliva, cleansing with HF followed by cleansing with ZP (ZP‐SC‐HF‐ZP). Cylindrical resin composite blocks were luted to the zirconia surfaces with SAC (Clearfil SA Cement Automix, Kuraray, Inc., Tokyo, Japan). Specimens were subjected to shear forces at a cross‐head speed of 0.5 mm/min. Data were analyzed with Analysis of Variance and Tukey tests (α = 0.05). Results The bond strength values to zirconia were significantly influenced by saliva contamination (P < .05). The SC‐NC group showed the lowest bond strength values (5.6 ± 1.4 MPa; P < .05). All cleansing or pretreatment agents improved the bond strengths when compared to noncleansing groups, NC‐NC and SC‐NC. Conclusion In situations where saliva contamination is deemed unavoidable, application of ZP after try‐in of the zirconia restoration could be beneficial for the accurate cementation. Clinical Significance During try‐in sessions of fixed dental prostheses, zirconia ceramic restoration may come into contact with saliva and surfaces should be cleansed to obtain an optimal surface for adhesion. Application of zirconia primer to the sandblasted zirconia surface is recommended whether the surface is contaminated with saliva or not.

The aim of this study was to evaluate the effect of different output powers of Er,Cr:YSGG laser and the association with tribochemical silica coating on the bond strength between zirconia ceramic and two resin cements. One hundred ninety-two zirconia ceramic bars (IPS e-max ZirCAD Ivoclar Vivadent-) were sectioned (6 × 6 × 4 mm), sintered, and randomly divided into 12 groups for each cement system according to the surface treatment (n = 8): C-without treatment (control); R-tribochemical coating + resin cement (control); 2L-laser (2.0 W) + resin cement; 2LR-laser (2.0 W) + tribochemical coating + resin cement; R2L-tribochemical coating + laser (2.0 W) + resin cement; 2.5L-laser (2.5 W) + resin cement; 2.5LR-laser (2.5 W) + tribochemical coating + resin cement; R2.5L-tribochemical coating + laser (2.5 W) + resin cement; 3L-laser (3.0 W) + resin cement; 3LR-laser (3.0 W) + tribochemical coating + resin cement, R3L-tribochemical coating + laser (3.0 W) + resin cement; and RPHO-tribochemical + resin cement + photoactivation (control). After the surface treatment, the respective primers were applied, and resin cements, Multilink N, Ivoclar Vivadent (M), and Panavia F 2.0, Kuraray Medical Inc. (P), were inserted into Tygon molds which were bonded to the zirconia bars. Each specimen received two cements bars. After 24 h of storage in a relative humidity (100%) at 37 °C, they were evaluated by the microshear test speed of 1 mm/min. The microshear values were analyzed by one-way ANOVA and Tukey's test (α = 0.05). ANOVA showed statistically significant differences among the evaluated groups. The highest bond strength was observed in RPHO, which statistically differed from all groups. The lowest bond strength was observed in M2.5L (Multilink N) and in P3LR (Panavia F 2.0). It can be concluded that the lowest power output tested was suitable and showed bond strength values similar to tribochemical silica deposition. The light curing is important to adhesion and the tribosilicatizated surface achieves similar microshear values to untreated surface in absence of light.
