Denture adhesive compositions with sufficient initial adhesion to the gums that build up enough cohesive strength upon hydration with saliva to withstand the stresses occurring during food mastication and cushions the gums from contact with the denture during chewing. The adhesive comprises a mixed partial salt of an amino ethyl ethylene urea substituted polyalkylvinylether/maleic acid copolymer wherein the cations of the salt are selected from the group consisting of zinc, calcium, magnesium, strontium, zirconium, sodium, and potassium.

L'invention concerne des compositions de ciment présentant une adhésion initiale suffisante sur les gencives pour permettre de constituer une force de cohésion suffisante lors d'une hydratation au moyen de salive, afin de résister à des contraintes se produisant lors de la mastication alimentaire et de protéger les gencives du contact avec la prothèse dentaire lors de la mastication. Ce ciment comprend un sel partiel mélangé de copolymère d'acide polyalkyléther/maléique à substitution amino éthyle éthylène d'urée, les cations de ce sel étant sélectionnés dans le groupe contenant : zinc, calcium, magnésium, strontium, zirconium, sodium et potassium.
