Effect of Type of Surface Treatment and Adhesive System on Shear Bond Strength of Composite Resin to a Non-Precious Metal Alloy
Background and Aim: Fractured metal-ceramic restorations may be repaired with composite in some cases to postpone the fabrication of a new restoration. Knowledge about the bond strength can help predict the success rate of this treatment modality. The aim of this study was to assess the effect of two types of mechanical surface treatment of metal along with the use of different adhesive systems...
متن کاملEffect of alloy type and surface conditioning on roughness and bond strength of metal brackets.
The effect of 5 different surface conditioning methods on bonding of metal brackets to cast dental alloys was examined. The surface conditioning methods were fine (30-microm) or rough (125-microm) diamond bur, sandblasting (50-microm or 110-microm aluminum oxide [Al2O3]), and silica coating (30-microm silica). Fifty disc-shaped specimens of 5 different alloys (gold-silver, palladium-silver, nic...
متن کاملThe Effect of Metal Primer on the Shear Bond Strength of Denture Base Resin to Base Metal Alloy after Electrolytic Etching and Laser Etching: An In Vitro Study
Background: The purpose of this study was to compare and evaluate the effects of metal primer on the shear bond strength of denture base resin to base metal alloy after electrolytic and laser etching. Materials and Methods: A total of 48 cobalt‐chromium (Co‐Cr) alloy specimens were fabricated. The specimens were divided into 6 groups of 8 specimens each. Group I: Sandblasting (control group). G...
متن کاملEffect of Metal Primers on Bond Strength of a Composite Resin to Nickel-Chrome Metal Alloy.
This study evaluated the effects of three metal primers and one multi-mode adhesive system on the shear bond strength (SBS) of a flowable composite resin to nickel-chrome metal alloy (Ni-Cr). Ninety plates were cast from Ni-Cr and divided in nine groups (n=10). The surfaces were sandblasted with Al2O3 and primed with three adhesive primers: Alloy Primer (AP), Universal Primer (TP) and RelyX Cer...
متن کاملEffect of Enamel and Dentin Surface Treatment on the Self-Adhesive Resin Cement Bond Strength.
The aim of this study was to evaluate the effect of enamel and dentin surface treatment on the micro-shear bond strength of self-adhesive cement. Seventy-two extracted third molars had their crowns embedded in acrylic resin and worn to obtain a flat enamel or dentin surface. The enamel and dentin specimens were randomly assigned to 8 groups (n=12) that were based on surface treatment (11.5% pol...
متن کاملEffect of enamel surface treatment on the bond strength of metallic brackets in rebonding process.
Bond failure after rebonding for newly placed brackets can be reduced by appropriate enamel surface treatment. This in vitro study investigated the effect of two enamel surface treatments on the bond strength of metallic brackets in the rebonding process. After debonding the brackets and removing the residual adhesive on the enamel surface of 50 upper premolar teeth, the teeth were divided into...
