“…A previous study showed that the durability of the bond strength between a silanetreated ceramic surface and the resin cement decreased with thermal cycling or water storage (16). Some studies have shown that, depending on the type of the silane, thermal cycling may have a significant effect on bond strength reduction of the ceramic and resin interface (17,18). Previous studies showed that the application of silane followed by resin cement was partially effective in water storage conditions or after thermal cycling for decrease of the bond strength (19).…”

The aim of this study was to evaluate the effect of different number of thermal cycles on the shear bond strength (SBS) of metallic orthodontic brackets bonded to feldspathic ceramic by a composite resin. Twenty-five ceramic cylinders were etched with 10% hydrofluoric acid for 60 s and received two layers of silane. Brackets were bonded to the cylinders using Transbond XT and assigned to 5 groups (n=5): Group 1 -Control group (without thermal cycling); Group 2 -500 thermal cycles; Group 3 -5,000 thermal cycles; Group 4 -7,000 thermal cycles and Group 5 -10,000 thermal cycles. Light-activation was carried out by Radii Plus LED. SBS testing was carried out after 24 h of storage in deionized water and thermal cycling (5/55 o C and 30 s dwell time). Five brackets were bonded to each cylinder, totalizing 25 brackets for each group. Data were submitted to one-way ANOVA and Tukey's test (α=0.05). The Adhesive Remnant Index (ARI) was evaluated at 8× magnification. The SBS (MPa) of control group (9.3±0.8), 500 (9.0±0.7) and 5,000 (8.4±0.9) thermal cycles were significantly higher than those after 7,000 (6.8±0.6) and 10,000 (4.9±1.0) thermal cycles (p<0.05). The ARI showed a predominance of Scores 0 (adhesive failure) prevailed in all groups, as shown by the ARI, with increased scores 1 and 2 (mixed failures) for control group and 500 thermal cycles. In conclusion, thermal fatigue may compromise the bonding integration between metallic brackets and ceramic restorations. For in vitro testing, use of at least 7,000 cycles is advised to result in significant fatigue on the bonding interface.

“…Heating of silane on the surface of ceramics can promote better adhesion between this material and resin composite (3,5,11,22). The heating of silane on the surface of ceramics can eliminate water, alcohol and byproducts of the reaction and help to complete the condensation reaction of silanesilica promoting the formation of siloxane (22).…”

“…This bond is usually created via two mechanisms: micro-mechanical attachment by hydrofluoric acid (HF) etching and/or sandblasting, and chemical bonding by a silane coupling agent (3). Effective etching of the ceramic surface is considered an essential step for the clinical success of indirect ceramic-bonded restorations and direct ceramic repair procedures (4).…”

The aim of this study was to evaluate the influence of ceramic surface treatments and silane drying temperature on the microtensile bond strength (μTBS) of a resin composite to a lithium disilicate ceramic. Twenty blocks (7x7x5 mm) of lithium disilicate-based hotpressed ceramic were fabricated and randomly divided into 4 groups: G1: acid etching with 9.5% hydrofluoric acid for 20 s and drying silane with room-temperature air; G2: acid etching with 9.5% hydrofluoric acid for 20 s and drying silane with 45 ± 5 °C warm air; G3: airborne-particle abrasion with 50 μm aluminum oxide particles and drying silane with 45 ± 5 °C warm air; G4: airborne-particle abrasion with 50 μm aluminum oxide particles and drying silane with air at room-temperature. After treatments, an adhesive system (Single Bond 2) was applied, light-cured and direct restorations were built up with a resin composite (Filtek Z250). Each specimen was stored in distilled water at 37 °C for 24 h and cut into ceramic-composite beams with 1 mm 2 of cross-sectional area for μTBS testing. Statistical analysis was performed with one-way ANOVA and StudentNewman-Keuls test (α=0.05). μTBS means (S.D.) in MPa were: G1: 32.14 (7.98), G2: 35.00 (7.77) and G3: 18.36 (6.17). All specimens of G4 failed during the cutting. G1 and G2 presented significantly higher μTBS than G3 (p<0.05). There was no statistically significant difference between G1 and G2 (p>0.05). As far as the bond strength is concerned, surface pretreatment of lithium-disilicate ceramic with hydrofluoric acid and silane application can be used as an alternative to repair ceramic restorations with composite resin, while surface pretreatment with sandblasting should be avoided.

“…Nevertheless, this surface layer of coupling agent is unnecessary for the bonding process, and may even be detrimental (14,15). Removing the outermost layer of the silane film and leaving the most stable and chemisorbed layer on the ceramic surface improves the bond strength with the restorative interface (14).…”

Silanated Surface Treatment: Effects on the Bond Strength to Lithium Disilicate Glass-Ceramic

et al. 2015

View full text Add to dashboard Cite

The aim of this study was to evaluate the effect of silanization protocols on the bond strength of two resin cements to a lithium disilicate glass-ceramic. Thirty-two ceramic discs were assigned to 2 groups (n=16): G1 -dual-cured resin cement and G2 -lightcured resin cement. Four subgroups were evaluated according to the used silanization protocol. The glass-ceramic was etched with 10% hydrofluoric acid for 20 s and silane was applied for 1 min, as follows: CTL -according to the manufacturer's instructions; HA -dried with hot air; NWA -washed and dried with water and air at room temperature; HWA -washed and dried with hot water and hot air. Thereafter, adhesive was applied and light-cured for 20 s. Silicon molds were used to prepare resin cement cylinders (1x1 mm) on the ceramic surface. The specimens were stored in deionized water at 37 °C for 48 h and subjected to a micro-shear test. The data were submitted to statistical analysis (α=0.05). Group G1 showed higher bond strengths than G2, except for the CTL and NWA subgroups. Differences as function of the silanization protocol were only observed in G1: HWA (25.13±6.83)≥HA (22.95±7.78)≥CTL(17.44±7.24) ≥NWA(14.63±8.76). For G2 there was no difference among the subgroups. In conclusion, the silanization protocol affected the resin cement/ceramic bond strengths, depending on the material. Washing/drying with hot water and/or hot air increased only the bond strength of the dual-cured resin cement.S i l a n a t e d S u r f a c e T r e a t m e n t : Effects on the Bond Strength to Lithium Disilicate Glass-Ceramic
