Reactivity and Bond Strength of Universal Dental Adhesives with Co-Cr Alloy and Zirconia

Abstract

The aim of this study was to evaluate (a) the reactivity of six universal dental adhesives with polished cobalt-chrome (Co-Cr) alloy and zirconia (3Y-TZP) surfaces; and (b) to assess the shear bond strength (SBS) of a resin composite with polished and alumina-blasted surfaces as mediated by these adhesives. The products tested were Adhese Universal (AD), All-Bond Universal (AB), Clearfill Universal Bond (CB), G-Premio Bond (GP), Prelude One (PO) and Scotchbond Universal (SB). The reactivity on polished substrates was evaluated by reflection infrared microscopy (RFTIRM). The roughness parameters of polished and 50 μm alumina grit-blasted surfaces were assessed by optical profilometry. The SBS of the composite bonded to the substrates treated with each adhesive (n = 10/product) was evaluated after 1 week of storage (H2O/37 °C) by Weibull statistics. Evidence of phosphate interaction with polished substrates was obtained by FTIRM, with higher peaks on the alloy. Alumina-blasting increased all roughness parameters with higher values on the alloy. AD, CB were the strongest (σ0) treatments on alloy surfaces and AD, CB, AB, SB on zirconia. GP was the weakest on both substrates and the least reliable (β) on alloy. On polished alloy GP, PO performed better (σ0), whereas on zirconia there were no significant differences. All adhesives showed more prominent reaction with the Co-Cr alloy than with 3Y-TZP.

Adhesion between Biocomposites and Different Metallic Structures Additive Manufactured

“…As shown in Table 7, the pure Ti substructure obtained by casting manufacturing [28] present lower adhesion values to resin cement even if methods were applied to improve the adhesion process by sandblasting with alumina and application of metal primer (7.5 MPa) or engraved with hydrochloric acid and application of metal primer (6.1 MPa). The shear bond strength of pure Ti adhesion to GC Fuji [29] was approximately the same as the values recorded in this study (8.5 MPa) and compared to resin cement (Panavia and Rely X U200) they increased considerably (17)(18)(19)(20)(21)(22)(23)(24)(25)(26). The same CAD-CAM milling technique was used by Korkmaz [17] to obtain a Ti6Al4V substrate.…”

“…Regarding the GSUNIVERSAL group that reached the highest adhesion values, both immediately and after aging, these results only confirm what was reported by researchers such as Nima, et al (1), Papadogiannis, et al (16), Jamel, et al (18), Al-Heou and Swed (29), and Bankoğlu, et al (30). The GSUNIVERSAL group was sandblasted and immediately afterwards silane and a universal adhesive (Single Bond Universal®, 3M.…”

“…Indeed, our study only confirmed what was reported by Marchesi, et al (35), who found that after having kept the samples in water for one-year, low values were obtained when using a universal adhesive system, since the stability of the interface gets lost over time. In the long term, 10-MDP can absorb moisture due to the phosphate radical, which would cause a degradation of the polymer network and consequently, a reduction in the bond strength of the materials (16,36,37). In any case, in our study, despite the fact that the initial values decreased with aging, they are still interesting and good.…”

“…The literature reports that the composition of these materials incorporates active monomers, whether sulfur, phosphoric or carboxylic, such as biphenyl-dimethacrylate (BPDM) and 10 methacryloxydecyl dihydrogen phosphate (10-MDP), which could act on the metal surface with particularly good results (1,7,14,15). However, dental clinicians and students could be confused and overwhelmed by these new products and techniques, since most studies have focused on adhesion to enamel and dentin and not so much on the bonding of metal alloys to different types of materials such as ceramics or zirconia (1,16).…”

“…In addition to the various monomers they contain, these resins are also used to bond ceramic, zirconium, or metal substructures with resin-containing materials. [ 27 ] In particular, previous studies indicated that 10-methacryloxydecyl dihydrogen phosphate (MDP) monomer-containing resins increase the bond of titanium with resin materials. [ 25 26 27 28 ] This study used a UB containing a three-dimensional self-reinforcing monomer (3D-SR) monomer with phosphate groups similar to the MDP monomer.…”
