The influence of electron beam irradiation on the shear bond strength of glass-reinforced frameworks and veneer composites

Abstract

The bond between glass fibre framework and veneer composite can be achieved by silane coupling agents or by monomers that penetrate into a polymer network. However, it has been clinically demonstrated that his bond can fail. This study investigated whether electron beam irradiation improved the bond strength of fibre-frameworks and veneer composite with and without additional coupling agents.

In Vitro Evaluation of Shear Bond Strength and Mode of Failure of the Interface between an Indirect Composite Bonded to Fiber‐Reinforced Composite Substructures

“…These failures can be attributed to improper framework design, 15–17 high bending tendencies of the framework materials, 18 and insufficient bond strength between framework and veneering material 13,14,19 . Although several attempts have been made to increase the bond between the FRC substructure and the veneering composite resin, this issue is still of great concern 20–22 . In a previous paper, 23 the shear bond strength of a light‐cured veneering composite bonded to FRC substrates was tested.…”
