1. A method for producing a dental crown composite comprising the steps of:

  • (a) providing a clean dental crown substrate surface;

    (b) depositing onto the substrate surface an exogenous coating of inorganic oxide to a desired thickness on the substrate surface to enhance adhesion between the substrate and subsequently applied silane coupling agent;

    (c) bonding a layer of silane coupling agent to the oxide coating; and

    (d) applying a polymeric resin to the exposed silane coupling layer.
