Effectiveness of pre-silanization in improving bond performance of universal adhesives or self-adhesive resin cements to silica-based ceramics: Chemical and in vitro evidences

Adhesion behavior of conventional and high‐translucent zirconia: Effect of surface conditioning methods and aging using an experimental methodology

“…However, the silane contained in universal adhesives could have reduced capacity to bond to silica-enriched surfaces, due to silanol condensation. 60,61 Even when the roughness values were statistically similar, the different μTBS values between these groups suggests that tribochemical treatment has a positive effect on the adhesive behavior.…”

“…In addition, no silanization was performed, since the manufacturer of the universal adhesive used in this study does not recommend the use of silane separately, as it already contains silane in its composition. However, the silane contained in universal adhesives could have reduced capacity to bond to silica‐enriched surfaces, due to silanol condensation . Even when the roughness values were statistically similar, the different μTBS values between these groups suggests that tribochemical treatment has a positive effect on the adhesive behavior.…”

Long-term evaluation of warm-air treatment effect on adaptation of silane-containing universal adhesives to lithium disilicate ceramic

“…This was attributed to a premature hydrolysis of γ-MPTS in the acidic conditions of one-bottle self-etch adhesives followed by a dehydration condensation of silanols into oligomers which can no longer bond to glass 12) . This mechanism was also confirmed using nuclear magnetic resonance (NMR) 11) , X-ray photoelectric spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) 13) . A simple way to prevent the pre-hydrolysis and self-condensation is to divide the universal adhesive components into two bottles because the silane can be mixed with acidic monomers just before application 14) .…”

“…This is in agreement with previous studies which have reported low bond strengths of one-bottle silane-containing universal adhesives to glass ceramics 10,11) . The plausible reason is that γ-MPTS was pre-hydrolyzed in the acidic conditions of one-bottle universal adhesives and the silanol underwent a selfcondensation into inactive oligomers 11,13) . On the other hand, the premature hydrolysis is prevented in the twobottle universal adhesive BL because the silane is mixed with the acidic monomers just before the application.…”

Bicyclo[4.2.0]octa-1,3,5-trien-3-yl-dimethyl((E)-styryl)-silane

“…Silicon organic compounds are widely used as intermediates in various syntheses and as target substances in industrial chemistry. Polysiloxanes and polysilanes are known as coupling agents for enhanced adhesion [1,2]. They increase mechanical and dielectric properties of composites [3], improve dispersion of pigments and industrial minerals, provide crosslinking, immobilize catalysts, and bind biomaterials [4].…”
