Abstract:
:The purpose of this study was to evaluate the effect of acidic priming agents on adhesive bonding to SUS XM27 stainless steel. Disk steel specimens were primed with one of the following materials; Acryl Bond, All-Bond 2 Primer B, Alloy Primer, Estenia Opaque Primer, Eye Sight Opaque Primer, Metal Primer II, M.L. Primer, MR Bond, and Super-Bond Liquid. The specimens were then bonded with an acrylic resin designed for denture repair (Repairsin), and bond strengths were determined. Unprimed specimen was used as control. The average bond strengths before thermocycling varied from 21.3 to 51.0 MPa, whereas post-thermocycling bond strengths ranged from 3.0 to 37.0 MPa. Of the nine priming agents, the Acryl Bond, All-Bond 2 Primer B, Estenia Opaque Primer, and MR Bond materials showed significantly higher bond strength after application of thermocycling. Within the limitation of the current experimental settings, it can be concluded that the use of the four acidic priming agents is recommended for bonding SUS XM27 stainless steel with Repairsin self-polymerizing repair material.
