“…After bonding, all the specimens were stored in distilled water at 37 °C for 24 h. Ten specimens from each group were tested for adhesion strength (baseline or dry values), and the remaining ten specimens were subjected for aging simulation. The adhesion strength test procedure was in accordance with DIN 13990-1/-2 [13] and the specimen allocation was in accordance with the previous study [14]. For adhesion strength test, the specimens were oriented vertically in a custom made jig of a universal testing machine (Instron Corporation, Canton, MA, USA).…”

The objective of this study is to evaluate the effect of an experimental adhesive silane blend system in achieving optimal orthodontic bonding to zirconia surfaces. Also, the effect of the sandblasting distance on the adhesion strength and surface roughness of the zirconia bonding surface was determined. A total of 180 zirconia specimens were used for 3 test groups (n = 60), and then grit-blasted with various distance (5 mm, 10 mm and 15 mm). The grit-blasted specimens were allocated to three silanizations (n = 30): with 1.0 vol. % 3 methacryloyloxypropyltrimethoxy-silane (EP1) or their blends with 0.5 % (EP2), and 1.0 vol. % (EP3) 1, 2-bis-(triethoxysilyl) ethane (all in ethanol/water). Premolar brackets were bonded to zirconia specimen surfaces using Transbond™ XT adhesive resin. Next, ten specimens from each subgroup were subjected to thermo-cycling of 5000 cycles. Adhesion strength tests were performed at baseline (dry), and after thermo-cycling. The grit-blasted specimens were studied by scanning electron microscopy (SEM) and their surface roughness was evaluated. Contact angles and wettability of the primers on the zirconia surface was determined. The highest surface roughness was 0.69 ± 0.0097 μm for specimens grit-blasted at a distance of 5 mm (group 1), and the lowest surface roughness was 0.29 ± 0.0078 μm for the control specimens. Significant differences in the mean surface roughness were observed between the study groups (P < 0.05). ANOVA showed a significant influence of the grit-blasting distance, silane blend and artificial aging on the shear bond strength values (P < 0.05). The highest adhesion strengths were obtained for baseline specimens irrespective of the grit-blasting distance or the silane primer blend system used. The water contact angle of the control zirconia specimen was 53.5° and the contact angle ranged between 3-7° after primer coating. Grit-blasting at 10mm and silane primer blend system of 1.0 vol% 3-methacryloyloxy-propyltrimethoxysilane + 0.5 vol. % 1,2-bis-(triethoxysilyl) ethane demonstrated optimal orthodontic bonding with least surface damage to the zirconia surface.

“…Silica‐coating followed by application of diverse functional silane monomers promotes resin Ti adhesion differently in the laboratory conditions: Reactive acrylate and methacrylate functional silanes contribute to durable adhesion, 19,20 and even isocyanato (OCN‐) functionality suggests promising, durable bonding 14 . Interestingly, silane blends for adhesion promotion might be promising in orthodontic bonding, 21–23 also in repair of amalgam restorations with resin composite, 24 and, moreover, antibacterial ammonium silanes might be potential in endodontic irrigation 25,26 . However, available ready‐to‐use silanes for adhesion promotion dentistry are somewhat different from each other 27 .…”

The presence of Si on the Ti surface is quintessential for a strong, durable silane‐based adhesion utilized in several dental applications. Silica‐coating and silanization form durable ≡Si‐O‐Si≡ bonds, which might have a positive effect on resin‐Ti adhesion. This laboratory study studied the effect of strong acids, their blends, and silica‐coating on Ti and resin‐Ti bonding. One‐hundred sixty‐eight c.p. grade 2 polished Ti samples (10 mm × 10 mm × 1 mm), out of which 96 were etched with 9% and 12%HF, a blend of 35%HCl+85%H3PO4 and a blend of 69%HNO3+35%HCl at 60°C, each for 2 min. One half was silica‐coated (Rocatec™ Plus, 110 μm SiO2‐coated‐Al2O3). Sixty Ti samples were first silica‐coated, and then, 48 of them were etched with 9%HF, 12%HF, a blend of 35%HCl+85%H3PO4, and a blend of 69%HNO3+35%HCl at 60°C for 2 min. SEM, EDX, XPS, and Ra analyses were carried out. Polished Ti samples were controls. All silanizations were carried out with a blend of 0.3 vol% 1,2‐bis‐(triethoxysilyl)ethane+1.0 vol% 3‐acryloxypropyltrimethoxysilane. Multilink™ Automix self‐adhesive resin composite cement was used in adhesion testing, and the samples were artificially aged followed by enclosed‐mold micro‐shear test on day 1 and weeks 1, 4, and 8. Failure mode analysis and statistical analysis with one‐way/two‐way ANOVA (p < 0.05) were carried out. HF etching produced the highest surface roughness. XPS analysis identified after etching with HF a variety of Ti and Si ions: Ti4+, Ti3+, Ti2+, and Ti0 and, on the other hand, Si4+, Si3+, and Si2+. A gradual decrease in adhesion strength was observed after artificial aging. Adhesive and cohesive failures were observed.

“…In particular, 3-acryloxypropyltrimethoxysilane (ACPS) and a cross-linking silane, bis-(1,2-triethoxysilyl)ethane (BTSE) have shown promising adhesion promotion in laboratory experiments. A functional silane coupling agent combined with a crosslinker silane might provide hydrolytically more stable and durable bonding 9) . Over the last decades the properties of titanium (and its alloys) have made it a material of choice in implant dentistry.…”
