Adhesive bonding of resin cements to cast titanium with adhesive primers

Abstract

The purpose of this study was to evaluate the effects of adhesive primer applications on the bond strength of resin cements to cast titanium. Four adhesive primers - Metaltite, Metal Primer II, Alloy Primer and Ceramic Primer - and their respective resin cements - Bistite II DC, Link Max, Panavia F 2.0, RelyX Unicem and RelyX ARC - were tested. Cast plates were prepared from titanium ingots (n=6 specimens/cement) and had their surfaces airborne-particle abraded with Al2O3 (50 μ m). Three resin cement cylinders were built on each bonded titanium surface, using a cylindrical translucent tubing mold and were subjected to micro-shear testing. Data were analyzed statistically by two-way ANOVA and Tukey's post-hoc test (α=0.05). The application of Metal Primer II and Ceramic Primer resulted in significant higher bond strength for Link Max and RelyX Unicem resin cements, respectively, than nonuse of adhesive primers. Panavia F 2.0 and RelyX ARC yielded high bond strength means with or without adhesive primers. The use of adhesive primers might increase the bond strength to cast titanium depending on the resin cement used.

Effect of Metal Primers on Bond Strength of a Composite Resin to Nickel-Chrome Metal Alloy

“…The micromechanical retention can be obtained by sandblasting with aluminum oxide abrasive particles, while the chemical bonding results from functional monomers of the metal primers, which are able to react and bond to the surface oxide layer of dental alloys (7,(17)(18)(19). This layer is formed on the surface of most metal alloys exposed to oxygen and/or high temperatures (19).…”

“…Sandblasting also standardized the metal surface (19), in order to accurately assess the influence of thermocycling and application of metal primers and adhesive system on the SBS of composite resin to Ni-Cr metal alloy. Thermocycling was used to produce aging of metal alloy-composite interfaces, because the temperature variations are able to shrink and expand resin-based materials involved in this interface (adhesives and composite), which may compromise the bond and reduce the bond strength of composite resin to Ni-Cr alloy (12).…”

“…However, another study demonstrated that CP was effective when applied to conditioned titanium. According to the authors, CP can improve the wettability, which may be responsible for increasing the bond strength to that alloy (19).…”

Adhesive bonding of resin composite to various titanium surfaces using different metal conditioners and a surface modification system

“…The use of titanium for dental implants and metal ceramic restorations, such as cast restorations or partial dentures, has increased over the last years because of their biocompatibility and optimum mechanical properties 6,9,23,29 . However, low bond strengths between titanium and composite veneering systems have been reported 3,11,20,21,29,32 .…”

Evaluation of experimental phosphate and sulfur-based primer bonding to metal casting alloys

“…In its composition, the primer Alloy Primer -Kuraray contains the monomers 6-(4-vinylbenzyl-n-propyl)amino-1,3,5-triazine-2,4-dithiol (VBATDT) and 10-methacryloyloxydecyl dihydrogen phosphate (MDP). The VBATDT monomer has affinity for only some metal elements, such as Au, Ag, Pd, Pt [16] and Cu [17]. The MDP is effective for use with nonprecious metal alloys [18] and its ester phosphate group increases the chemical bonding affinity with the surface layer of chromium oxide formed of the cobalt-chrome alloy surface [19].…”
