“…However, whereas some of these t reatments have shown good results, 4,6,8,26 other methods have not proven their effectiveness completely. 7,9,20,21,27 In the present study, the application of glass to the ZrO 2 surfaces improved the bond strength between the ceramic and resin cement, regardless of the technique (air blast or gel) or concentration of the gel (15, 25 or 50% of glass by weight). The increase in the bond strength probably occurred due to addition of silica to the surface of the substrate.…”

This study evaluated the influence of an alternative surface treatment on the microshear bond strength (μsbs) of zirconia-based ceramic. Thirty-five zirconia disks were assigned to five groups according to the following treatments: Control (CO), glass and silane were not applied to the zirconia surface; G1, air blasted with 100μm glass beads + glaze + silane; G2, a gel containing 15% (by weight) glass beads applied to the ceramic surface + glaze + silane; G3, a gel containing 25% (by weight) glass beads applied to the ceramic surface + glaze + silane; and G4, a gel containing 50% (by weight) glass beads applied to the ceramic surface + glaze + silane. The specimens were built up using RelyX ARC ® , according to the manufacturer's recommendations, and inserted in an elastomeric mold with an inner diameter of 0.8 mm. The μsbs test was performed using a testing machine at a crosshead speed of 0.5 mm/min. ANOVA and Tukey's test (p < 0.05) were applied to the bond strength values (in MPa). CO (15.6 ± 4.1) showed the lowest μsbs value. There were no statistical differences between the G1 (24.9 ± 7.4), G2 (24.9 ± 2.3), G3 (35.0 ± 10.3) and G4 (35.3 ± 6.0) experimental groups. Those groups submitted to surface treatments with higher concentrations of glass showed a lower frequency of adhesive failures. In conclusion, the glass application improved the interaction between the ceramic and the luting cement.

“…A rough surface increases the surface area, improves wettability by reducing surface tension, and creates micromechanical retention. Al 2O3 air abrasion is one of the common methods used to increase surface roughness 8,19,32,33) . Some investigators suggested that superior bonding to zirconia was obtained when with airabraded surfaces [34][35][36][37] .…”

Effect of ultrashort pulsed laser on bond strength of Y-TZP zirconia ceramic to tooth surfaces

et al. 2015

There is limited knowledge about the effects of ultrashort pulsed laser on zirconia ceramic surfaces. The aim of this study was to evaluate the effects of ytterbium (Yb)-doped fiber laser and other surface treatment methods -namely, sandblasting with 110 µm aluminum oxide or 30 µm silica-coated alumina on shear bond strength (SBS) of zirconia to tooth surface. A total of 128 zirconium oxide disks were made by using CAD-CAM technology. Disk surfaces were sandblasted with Al2O3 particles or silica-coated alumina or irradiated with Yb-doped fiber based nanosecond pulsed laser at 85W output power at 25 kHz. Disks were luted to dentin using two different resin cement. SBS of each specimen was measured. Results were statistically analyzed using two-way analysis of variance (ANOVA) and Bonferroni and Dunnett tests (p<0.005). Highest bond strength was obtained when zirconia surface was pretreated with Yb-doped fiber-based nanosecond pulsed laser regardless of the resin cement used.

“…The morphological pattern obtained with 50-µm aluminum oxide particles was more effective for micromechanical bonding compared to airborne particle abrasion with 100-µm aluminum oxide particles, according to the findings that are consistent with other studies. [15][16][17][18][19][20][21] Using 9.5% hydrofluoric acid etching changed the surface topography of IPS Empress 2 and Cergogold ceramics, creating a topography similar to a honeycomb for Cergogold ( Figure 4C) and elongated the crystals with shallow irregularities for IPS Empress 2 ( Figure 3C). The chemical-etching process can be explained by the preferential reaction of hydrofluoric acid with the silica phase of the feldspathic ceramic to form hexafluorosilicates, which are removed by rinsing with water.…”

“…[9][10] The silicate-based ceramic surfaces are etched, often using hydrofluoric acid, which changes its microstructure by dissolution of one of the glassy phases of porcelain and by creating an appropriate microstructure for bonding. [11][12][13][14] Another pre-bonding treatment for ceramic surfaces is airborne aluminum oxide particle abrasion, [15][16] which similarly changes the microstructure of the ceramic surface. The interaction of the luting agent silicate ceramic can be enhanced by the application of a silane coupling agent.…”

SUMMARYObjective. The current study evaluated the micro-shear bond strength between a resin luting agent and four strengthened all-ceramic systems under different surface treatments.Methods. Rectangular specimens of IPS Empress 2 (Ivoclar-Vivadent), Cergogold (DeguDent), In Ceram Alumina (Vita) and Cercon (DeguDent) ceramics were fabricated and randomly divided into three groups: 1-no treatment; 2-etched with 9.5% hydrofluoric acid and 3-airborne-particle abraded with 50 µm aluminum oxide particles. The ceramic surfaces of the specimens were coated with a silane agent (Clearfil Porcelain Bond, Kuraray), then bonded with a resin-luting agent (Panavia F, Kuraray). A micro-shear bond test was carried out to measure the bond strength. Moreover, each ceramic surface was observed morphologically by scanning electron microscopy. The results were submitted to analysis of variance and Tukey's posthoc analysis (p<0.05). SMP Torres • GA Borges • AM Spohr AADB Cury • S Yadav • JA Platt Clinical RelevanceThe bond strength between ceramics and a resin luting agent is affected by the ceramic surface treatment, which is dependent on the ceramic composition. Laboratory ResearchResults. The bond strength of all ceramic systems evaluated was affected by the surface treatments (p<0.05). The highest values for bond strength of IPS Empress 2 were found when the surface treatment used was hydrofluoric acid etching, followed by airborne particle abrasion treatment. On the other hand, airborne particle abrasion treatment and acid etching were not different for Cergogold and In Ceram Alumina ceramics, but they were higher when compared to the control (p<0.05). The highest bond strength to Cercon was found when it was treated with airborne particle abrasion with aluminum oxide. The SEM photographs showed that the hydrofluoric acid etching treatment affected the surface of IPS Empress 2 and Cergogold; however, Cercon and In Ceram surface morphology were not changed by the hydrofluoric acid etching. The airborne particle abrasion treatment altered the Cercon ceramic morphology but it did not change the other ceramic's surface.
