  • Patent number: 6756417
    Abstract: Dental bonding compositions and methods for promoting adhesion of an amalgam-based restorative material to a dental substrate. The inventive compositions include one or more polymerizable resins that are able to adhere to a dental substrate when at least partially polymerized, one or more polymerization photoinitiators in an amount so as to result in partial polymerization of the resin when the compositions are irradiated with radiant energy, and one or more chemical initiators (e.g., benzoyl peroxide) that cause further polymerization of the resin when the composition is contacted with an amalgam restorative. A bonding composition applied to a dental substrate and irradiated with radiant energy is more polymerized in a region adjacent to the dental substrate, while a less polymerized inhibition layer forms in the region of the surface. Packing an uncured amalgam into the dental preparation mechanically disrupts the inhibition layer so as to form peaks, troughs and other irregularities.

  • Patent number: 6592990
    Abstract: A novel adhesive formed in situ in a microcapsule and method for forming such a pressure sensitive or flowable adhesive in situ in a microcapsule is disclosed. The method for forming the novel adhesive comprises providing an aqueous mixture of wall material in water; adding a substantially water insoluble core material, free radical initiator, and a solvent for the pre-polymers to the aqueous mixture. The core material comprises a first addition polymerizable pre-polymer having a Tg of less than about 0° C., a flash point of at least 75° C., and a boiling point of at least 175° C. These are typically selected from acrylate or methacrylate type materials. Optionally included is a second addition polymerizable pre-polymer for providing cross-linking or interaction between polymer chains. High shear agitation is provided to the aqueous mixture to achieve a particle size of about 0.1 to 250 microns.
