Effect of Acidic Primers on Bonding Three Magnetic Steel Alloys with Tri-n-butylborane Initiated Methacrylic Resin

Abstract

The purpose of this study was to evaluate the effect of acidic primers on bonding magnetic steel alloys.Three alloys (XM27, 447J1, and AUM20) were primed with one of the following materials: Acryl Bond, Estenia Opaque Primer, Eye Sight Opaque Primer, M. L. Primer, or Super-Bond liquid. The specimens were bonded with a tri-n-butylborane initiated resin, and bond strength was determined both before and after thermocycling in water. Unprimed specimen was considered as the control.Average bond strength varied from 0 to 45.3 MPa for the XM27 alloy, 0.3 to 43.6 MPa for the 447J1 alloy, and 0.5 to 41.1 MPa for the AUM20 alloy. Of the five primers, Estenia Opaque Primer exhibited better adhesive performance than the other materials regardless of the type of steel alloy. It can be concluded that the use of the Estenia Opaque Primer, which contains an adhesive monomer (10-methacryloyloxydecyl dihydrogen phosphate; MDP), is recommended for bonding the three magnetic steel alloys with TBB-initiated resin.

Effect of sandblasting and various metal primers on the shear bond strength of resin cement to Y-TZP ceramic

“…This implied that MDP was superior to carboxylic monomer, such as 4-META and MAC-10, in terms of bonding characteristics. This result well agreed with other studies although the studies were carried out about titanium and other base metal alloys [32,33,44,45].…”

Effect of Single-liquid Priming Agents on Adhesive Bonding to Aluminum Oxide of a Methacrylic Resin

“…Between the two phosphate monomers, i.e., hydrophobic MDP and hydrophilic methacrylate phosphate (MP), the former demonstrated better bond durability to base metal alloys than the latter 19,26) .…”

“…The results showed that carboxylic monomers rather than a silane monomer were effective for bonding alumina. Similarly, other studies demonstrated the effectiveness of MDP monomer in bonding dental base metal alloys and base metals [19][20][21][24][25][26] . Both base metal alloys and alumina are usually covered with a metal oxide layer.…”

“…To date, various acidic adhesive systems for bonding restorations and fixed partial dentures have been introduced [18][19][20][21] . However, limited information is available concerning the bonding behavior of highpurity alumina, especially in relation to the chemical ingredients or functional monomers in the bonding agents 3) .…”

Fixation of magnet assembly to denture base using alternative resins

“…Fixation strengths would depend on both the adhesive strength and the mechanical retention between the magnetic assembly and the fixation materials 29,30) . In the present study, application of a conventional metal primer and Super-Bond was examined to investigate the effectiveness of the adhesive strength.…”
