Effect of multi-purpose primer on bonding of acrylic resin to cast titanium and gold alloy after airborne-particle abrasion

Abstract

Surface treatment with primers containing functional monomers is a simple way to obtain high bond strength. Acidic functional monomers such as 10-methacryloyloxydecyl dihydrogen phosphate (MDP), which act on the oxide film produced on the surface of nonnoble metals, were initially used [5]. The effectiveness of MDP on titanium has been previously demonstrated [6][7][8]. Tsuchimoto et al.[9] refered to the condition of titanium surface being important for bonding using MDP. MDP and other acidic functional monomers have been known to be ineffective on noble metals, which do not produce oxide films. This problem was solved by synthesizing organic sulfur compounds that act directly on the surface of noble metals. The first organic sulfur compound to be synthesized for this purpose was 6-(4-vinylbenzyl-n-propyl) amino 1,3,5-triazine-2,4-dithiol (VBATDT) [10]. VBATDT and other organic sulfur compounds have

Effect of luting system with acidic primers on the durability of bonds with Ti-15Mo-5Zr-3Al titanium alloy and its component metals

“…Specifically, EOP-and ALP-priming agents containing 10-methacryloyloxydecyl dihydrogen phosphate (MDP) monomers demonstrated good bonding durability (category A-a). This result agrees with previous studies, although the types of luting materials, titanium alloys, primers, and experimental conditions were not identical [11][12][13][14][15][16][17][19][20][21][22][23] . Tsuchimoto et al reported the effectiveness of MDP monomer on the adhesion of pure titanium.…”

“…The Ti-15Mo-5Zr-3Al alloy consisted of Ti, Mo, Zr, and Al, and no noble metal elements were incorporated. Four acidic primers for treating the Ti-15Mo-5Zr-3Al alloy and its component metals were selected because thione and sulfide monomers are known to be effective for priming noble metal alloys 15,23,34) but ineffective for priming base metals, including titanium 15,23) . The first null hypothesis was that the bond strength and durability of acrylic resin bonded to a titanium alloy would not be influenced by the type of priming agent.…”

“…Current bonding methods include mechanical retention 10) and surface modification of prostheses, but one of the most effective methods is the application of functional adhesive monomers to the adherend surface. Many reports have been published on bonding to titanium [11][12][13][14][15][16][17] and Ti-6Al-7Nb alloy 16,[18][19][20][21][22][23][24] , and the effectiveness of acidic functional monomers on base metal alloy has become apparent 25) . The bonding strength of titanium has been evaluated using primers containing carboxylic monomers 13) and hydrophobic phosphates [11][12][13][14][15][16] .…”
