“…The silane coupling agents must be activated by hydrolysis (SiOR→SiOH) to form (1) hydrogen bonding to the inorganic substrate surface at ambient temperature and (2) Si-O-substrate linkage via the condensation reaction between silanol (-SiOH) groups of silane coupling agent and hydroxyl (-OH) groups on the substrate, which is accelerated by thermal treatment at 110-150°C 20) . Therefore, twocomponent silane solutions or pre-activated silane solutions (i.e., mixtures of the silane coupling monomer, acid, water and various polar and non-polar solvents) are used in dentistry 17) . Although the function of the acid is to activate (hydrolyze) alkoxysilyl groups, silanols can begin to condense with each other, forming higher-molecular-weight oligomers/polymers over time in the presence of acid in the medium.…”

Resin bonding to zirconia ceramics is difficult to achieve using the standard methods for conventional silica-based dental ceramics, which employ silane coupling monomers as primers. The hypothesis in this study was that a silane coupling oligomer -a condensed product of silane coupling monomers-would be a more suitable primer for zirconia. To prove this hypothesis, the shear bond strengths between a composite resin and zirconia were compared after applying either a silane coupling monomer or oligomer. The shear bond strength increased after applying a non-activated ethanol solution of the silane coupling oligomer compared with that achieved when applying the monomer. Thermal treatment of the zirconia at 110°C after application of the silane coupling agents was essential to improve the shear bond strength between the composite resin cement and zirconia.

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

“…The first group consisted of a pre-activated silane (3-methacryloxypropyltrimethoxysilane; 3-MPS) dissolved in an ethanol/water solvent (Monobond-S, Ivoclar-Vivadent, Schaan, Liechtenstein).

“…The thermocycling and water storage of bonded specimens have been widely used for in vitro testing of resin-based dental materials to assess the resistance of bonded interfaces to hydrolytic degradation. [14][15] Thus, the objectives of this study were to evaluate, with a model of accelerated water aging, the effects of water storage and thermocycling on the microtensile bond strength of resin composite cores to silanized fiber posts and examine the micromorphologic characteristics of aged interfaces. The null hypothesis tested was that there are no differences in adhesive effectiveness and degradation resistance of 2 different silane coupling agents on fiber post/core build-ups after water storage.…”

SUMMARYThe hydrolytic stability of a pre-activated MPS silane (Monobond-S) and a 2-component 4-META/ γ γ-MPTS silane (Porcelain Liner M) to H 2 O 2 -etched quartz fiber posts was investigated using a modeling approach. Composite build-ups around silanized posts were stored dry for 24 hours, stored in deionized water at 37°C for 24 hours, 1 week, 1 month or they were thermocycled. Sectioned specimens were prepared for microtensile bond testing and SEM examination; 4-META/γ γ-MPTS silane produced a rapid decline in bond strength after 1 week and 1 month of water storage and after thermocycling. This was not apparent in pre-activated MPS silane. SEM revealed debonding along the post-composite interfaces, which were coupled with 2-component silane. The use of a hydrophilic resin monomer (4-META) for on-demand hydrolysis of the γ γ-MPTS silane expedited interfacial water sorption and hydrolytic degradation, which may be prevented with alternative coupling strategies.
