    • 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.
    • 本发明涉及包含烷基乙烯基醚 - 马来酸共聚物的混合盐的义齿粘合剂组合物,其中混合盐含有包含约5%至约50%锌阳离子的阳离子盐功能; 0%至约2.5%的选自铁,硼,铝,钒,铬,锰,镍,铜,钇,钛及其混合物的阳离子; 约30%至约60%的游离酸组分; 有效粘合量的镁阳离子; 和有效粘合量的选自钙,锶及其混合物的阳离子; 其中镁,钙和锶的总含量为约5%至约65%。 此外,本发明涉及包含上述组合物和至少一种非粘性自支撑层的义齿粘合剂组合物。 本发明还涉及一种通过将上述组合物直接应用到口腔的口腔,口腔或脊部或将其应用于两者的方法,从而将义齿增加到口腔的粘附力,然后将 假牙到口腔的脊或腭。
