Tensile bond strength of an adhesive resin cement to different alloys having various surface treatments

A study of self-adhesive resin cements for bonding to silver-palladium-copper-gold alloy — Effect of including primer components in cement base

“…When Ag-Pd-Cu-Au alloy restorations were cemented with adhesive resin cements, deterioration occurred at the bonding interface rather than within the cement material itself 43,44) . Therefore in this study, although SA did not show a significant decrease in SBS after thermocycling, it was probable that the cohesive strength of the cement adjacent to oxidized alloy surface might be greater than the bond strength of SA.…”

“…Other studies. 4 proved that metal type did not significantly affect tensile bond strength. However, alloy type and surface treatment affected site of debond location.…”

“…3 Clinicians may choose among several alloy types, surface treatments to be applied to the intaglio surface of the restoration, and must also select the most appropriate cementing agent, to maximize restoration longevity. 4 Titanium and titanium alloys are being increasingly used as an alternative material to make fixed prostheses, because of their excellent biocompatibility, corrosion resistance, low density, light weight, physical and mechanical properties. 5,6 It is a preferred metal for fabricating the prosthetic superstructure of an implant abutment since, use of different dental alloys for the superstructure of the implants leads to detectable galvanic corrosion.…”

“…5 Two important interfaces affect the ultimate bonding potential for a restoration to an abutment: Between the abutment and the adhesive cement and that between the cement and the intaglio surface of the prosthesis. 4 There are several factors that influence the retention-strength in cement-retained restorations including the properties of luting cements, surface area of the crown or the implant abutment and surface finish or roughness.…”

“…Little direct information is available regarding the effect of alloy selection on the strength and integrity of the metal-cement interface. 4 The bond at the restorative material/cement interface should rely on micromechanical retention in conjunction with chemical bonding. Airborne-particle abrasion with aluminium oxide particles is the most widely used method for providing micromechanical retention.…”
