    摘要： 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.

    摘要： 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. 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 dentures to the ridge or palate of the oral cavity.

    摘要： An improved housing for an electric toothbrush is disclosed. The improved housing provides two symmetrically positioned gripping members which assist the user in grasping the toothbrush particularly during brushing. Each of the gripping members includes a recessed gripping region having particular dimensional characteristics. The two gripping members are symmetrically arranged on the rearward sides of the toothbrush so that the brush may be used by both left-handed and right-handed individuals. A third gripping member may also be provided along the housing of the toothbrush.
