“…This is because these two interfaces determine the final bond strength of the restoration. All-ceramic restorations finished for cementation are usually already abraded by airborne particles in a dental laboratory to ensure micromechanical as well as chemical bonding with the luting agent 4) . After try-in of the restoration in the oral environment, the ceramic surface might become contaminated by saliva or blood.…”

Influences of contamination and cleaning methods on the bonding of resin cement to zirconia ceramics were examined. Airborne particle-abraded zirconia (IPS e.max ZirCAD) specimens were contaminated with saliva and cleaned with tap water (SC) or by application of 37% phosphoric acid (PA), Ivoclean (IC), or additional airborne particle abrasion (AB). Specimens without contamination served as controls. After application of Monobond Plus to the surface of the specimens, resin cement was mixed and inserted into a mold. Surface free energies of the specimens were determined by measuring contact angles. Surface treatment and storage conditions significantly influenced bond strength, while there was no significant interaction between the two factors. Surface free energies of the SC and IC groups were significantly lower than those of the other groups. Additional AB of saliva-contaminated zirconia increased the strength of bonding with the resin cement as well as increased surface free energy.

“…The source of the Al 2 O 3 was the Al 2 O 3 particles embedded into the alloy surface during blasting. In other studies, Al 2 O 3 contamination has also been found on the alloy surface after blasting with Al 2 O 3 particles (28,(34)(35)(36). However, the effect of this on the metal-ceramic bond strength remains unclear (29,35,37).…”

There is a dearth of dental scientific literature on the effect of different oxidation heat treatments (OHTs) (as surface pretreatments) on the bonding performance of cast and milled cobalt-chromium (CoCr) alloys. The objective of this study was to evaluate the effect of different OHTs on the bond strength between a ceramic and cast and milled CoCr alloys. Cobalt-chromium metallic specimens were prepared using either a cast or a milled method. Specimens were subjected to four different OHT methods: without OHT; OHT under normal atmospheric pressure; OHT under vacuum; and OHT under vacuum followed by sandblasting. The metal-ceramic bond strength was evaluated using a three-point bending test according to ISO9693. Scanning electron microscopy and energy-dispersive spectroscopy were used to study the specimens' microstructure and elemental composition. The bond strength was not affected by the CoCr manufacturing method. Oxidation heat treatment performed under normal atmospheric pressure resulted in the highest bond strength. The concentration of oxygen on the alloy surfaces varied with the different pretreatment methods in the following order: OHT under normal atmospheric pressure > OHT under vacuum > without OHT ≈ OHT under vacuum followed by sandblasting.

“…For titanium, there is evidence of superior performance of the laboratory devices [17,18], although this has not been confirmed in other studies [19]. For base and noble alloys, the results available are contradictory [20,2]. According to the manufacturers' information, all the powders used for intraoral tribochemical coating are based on 30 mm silica-coated alumina particles, usually produced by sol-gel silica precipitation on alumina particles [9].…”

A B S T R A C TObjectives: Encapsulated silane has been introduced in powders for tribochemical coating (SilJet Plus, SP), eliminating the need for a separate silane primer. The aim of the study was to comparatively evaluate the effect of SP on the surface properties and bond strength of a Co-Cr alloy with a resin composite. Methods: Co-Cr cast alloy disks were subjected to tribochemical treatments with CoJet (CJ), SilJet (SJ) and SP. Polished specimens were used as control (CR). The alloy surfaces were studied by optical profilometry (OIP; parameters Sa,Sz,Sdr,Sci), reflection FTIR microscopy (RFTIRM; CR,CJ,SJ silanized with S-Bond), scanning electron microscopy/energy dispersive X-ray microanalysis (SEM/EDX; Al + Si coverage), contact angle with water (CW) and shear bond strength with a flowable resin composite (SBS). Statistical analysis for OIP, Al + Si coverage, CW and SBS was performed by one-way ANOVA and Holm-Sidak multiple comparison tests and by Chi-square for the failure mode (a = 0.05). Results: CR demonstrated the lowest Sa,Sz,Sdr values from all sandblasted surfaces, excluding Sci of SJ. Among tribochemical treatments, no differences were found in Sa,Sz. CJ showed lower Sdr and SJ higher Sci. The peaks of SiÀ ÀOÀ À were very weak on CR, but detectable on CJ, SJ and SP, with no evidence of SiÀ ÀOÀ ÀCH 3 groups. The ranking of the statistical significant differences in CW measurements was SP > SJ + silane > CJ + silane > CR + silane. Well-defined Al and diffuse Si distributions were found on the alloy surface following tribochemical treatments. The maximum Al + Si coverage ranged between 50 and 54% (5000Â) and the random coverage between 7 and 11% (1000Â, p > 0.05 for both). Tribochemical treatments showed higher SBS from CR (p < 0.05), but with no statistically significant differences among them. CR demonstrated exclusively adhesive failures, whereas in tribochemically coated groups adhesive failures ranged from 10 to 20%. Clinical significance: Tribochemical treatments with encapsulated silane may be considered an efficient single-step alternative to conventional two-step systems for bonding to Co-Cr alloys, offering a significant reduction in chairside time.
