  • Title: Shear bond strengths of prosthodontic adhesive systems to a nickel-chromium-beryllium alloy.
    Author: Kolodney H, Puckett AD, Breazeale MS, Patterson KL, Lentz DL.
    Journal: Quintessence Int; 1992 Jan; 23(1):65-9. PubMed ID: 1631273.
    Abstract:
    Panavia, a composite resin luting agent containing phosphate monomers, bonds chemically to air-abraded base metal alloys and is particularly suited for cementing resin-bonded retainers. Another adhesive methodology (Silicoater system) incorporates a pyrolytically applied silica layer to metal substrates to promote bonding of a resin adhesive. The object of this study was to compare prosthodontic adhesive systems that incorporated the Silicoater system and/or Panavia. The results showed that the surface treatment that provided significantly higher shear bond strengths was the Silicoater system and a layer of unfilled resin. A second test evaluated use of Panavia as a metal opaquing material beneath laboratory light-curing resins. Results showed that Panavia Opaque material was displaced peripherally during placement of overlying laboratory composite resin veneers. This resulted in an uneven intermediate layer of Panavia.
