  • Patent number: 7008976
    Abstract: The present invention relates to a denture adhesive composition comprising mixed salts of an alkyl vinyl ether-maleic acid or anhydride copolymer and/or terpolymer with isobutylene wherein the mixed salt contains a cationic salt function comprising at least about 1% strontium cations, from about 1% to about 40% of zinc cations, from 0% to about 2.5% of a cation selected from the group consisting of iron, boron, aluminum, vanadium, chromium, manganese, nickel, copper, yttrium, titanium, and mixtures thereof; from about 36% to about 60% free acid component; and from 0% to about 65% of a cation selected from the group consisting of magnesium, calcium, and mixtures thereof. In addition, the present invention relates to denture adhesive compositions comprising the above composition and at least one non-adhesive self-supporting layer.
    Type: Grant

  • Patent number: 6617374
    Abstract: The present invention relates to a denture adhesive composition comprising mixed salts of an alkyl vinyl ether-maleic acid or anhydride copolymer and/or terpolymer with isobutylene wherein the mixed salt contains a cationic salt function comprising at least about 22.5% calcium cations, from about 15% to about 25% of zinc cations, of the total initial carboxyl groups reacted, the mixed salt containing from about 36% to about 50% free acid component. In addition the present invention relates to denture adhesive compositions comprising the above composition and at least one non-adhesive self-supporting layer. The present invention further relates to a method of increasing the adhesion of dentures to the oral cavity by applying the above compositions to dentures, directly to the oral cavity, palate or ridge of the oral cavity, or applying it to both, and thereafter securing the denture to the ridge or palate of the oral cavity.

  • Patent number: 6355706
    Abstract: The present invention relates to a denture adhesive composition comprising mixed salts of an alkyl vinyl ether-maleic acid copolymer wherein the mixed salt contains a cationic salt function comprising from about 5% to about 50% zinc cations; from 0% to about 2.5% of a cation selected from the group consisting of iron, boron, aluminum, vanadium, chromium, manganese, nickel, copper, yttrium, titanium, and mixtures thereof; from about 30% to about 60% free acid component; an effective adhesive amount of magnesium cations; and an effective adhesive amount of a cation selected from the group consisting of calcium, strontium, and mixtures thereof; wherein the total level of magnesium, calcium and strontium is from about 5% to about 65%. In addition the present invention relates to denture adhesive compositions comprising the above composition and at least one non-adhesive self-supporting layer.
