Bonding durability between acrylic resin adhesives and titanium with surface preparations

Abstract

The purpose of the present study was to evaluate the efficacy of pretreatment on the bonding durability between titanium casting and two acrylic adhesives. Cast titanium disk specimens treated with four polymer-metal bonding systems as follow: 1) air-abraded with 50-70 μm alumina, 2) 1)+Alloy Primer, 3) 1)+M.L. Primer and 4) tribochemical silica/silane coating system (Rocatec System). The specimens were bonded with M bond or Super-bond C&B adhesive. The shear bond strengths were determined before and after thermocycling (20,000 cycles). The surface characteristics after polishing, and for the 1) and 4) preparations were determined. The bond strengths for all combinations significantly decreased after thermocycling. The combination of Super-bond C&B adhesive and 2) led to significantly higher bond strength than the other preparations after thermocycling. The maximum height of the profile parameters for the polishing group was lower than other preparations.

Effect of Fiber Laser Irradiation on the Shear Bond Strength between Acrylic Resin and Titanium

“…Similarly, in a study conducted by Maruo et al [45], the processes of plasma beam application and sandblasting with Al 2 O 3 produce weaker results than the metal primer application with regard to the bond between the acrylic resin and the cobalt-chrome alloy. Several studies demonstrated that the only mechanical methods used in some studies were insufficient and that the application of chemical agents, such as silane and metal primers, was effective in enhancing the bond, which is supportive of our study [2, 3, 8, 9, 32, 33].…”

“…Therefore, various mechanical and chemical methods have been employed to enhance the adhesive bonding of acrylic resins to metal alloys. Electrolytic etching, chemical etching, silica coating, spark erosion, laser application, sandblasting with Al 2 O 3 , and the application of metal primers are the most commonly used methods developed for this purpose [2, 3, 6–12].…”

“…The technique of sandblasting with alumina particles is widely used for enhancing the bond between the metal alloys and PMMA [6, 13]. It has been reported in various studies that having been a chemical method, the application of various adhesive primers is a successful method that eliminates the need for mechanical surface treatment and that enhances the bond between the PMMA and the metal [2, 3, 5, 9, 10]. The metal primer application containing 10-methacryloyloxydecryl dihydrogen phosphate (MDP) is one of the adhesive primer applications that creates an excellent chemical bond between the PMMA and the metal [2, 3, 8, 11].…”

In some previous studies, it was reported that the use of MDP-containing primers was more effective in enhancing the bond between the metal and the PMMA than other primers [3, 4, 11, 14].…”

Chemical alteration of Ag-Pd-Cu-Au alloy surface by alumina air-abrasion and its effect on bonding to resin cement

“…Previous studies have reported that air-abrasion of silica-coated alumina particles (Rocatec system) can chemically modify material surfaces, leading to improve bonding properties [37][38][39][40] . Alumina air-abrasion has been considered to have a mechanical effect on adhesive bonding, but the chemical effects have not been clarified so far.…”
