The acrylic tooth-denture base bond: effect of mechanical preparation and surface treatment.
The bond strength of acrylic teeth to denture base resins was tested using a widely-accepted technique. The pre-treatments included abrading and grooving the teeth, the application of monomer and the application of a proprietary bonding agent. Each of the 360 specimens was tensile-tested until fracture, using a universal testing machine. When bonded to heat-cured resin, the grooved teeth had the highest mean bond strength while the grooved monomer-treated group had the lowest. When bonded to cold cure resin, the unabraded monomer-treated teeth had the highest mean bond strength and the unabraded group the lowest.
