Heyd et al teaches a non-adhesive denture composition for improving the fit and adaptation of dentures to the oral cavity compπsmg cellulose polymer or algmate, a demulcent selected from glycerine, sorbitol, and propylene glycol, and 50 % to 95% by weight water This reference also teaches that these compositions prevent the build-up of undesirable deposits such as plaque and have antibacterial and/or mycostatic effects Despite these teachings, a method of reducing or preventing calculus, plaque, and/or stam m the oral cavity, by applying a non-aqueous denture adhesive composition to the oral cavity, has not been suggested Despite the above-noted technologies as well as others, a need still exists for denture stabilizing compositions providing both improved hold and anticalculus or

stain, in the oral cavity frv applying a non-aqueous denture adhesive composition comprising a denture adhesive component and a non-aqueous vehicle These compositions provide the above benefits while

alkyl vinyl ether-maleic acid or anhydnde copolymer, in the form of a slurry, m an amount sufficient to provide the desired catiomc content desired m the end-product This is done at ambient temperature and then slowly heated to 70°-95°C with continuous vigorous mixing so as to prevent localized precipitation of the catiomc polymeric salt, mixing is continued to ensure that all the salt forming compound is reacted with the copolymer Alternatively, the AVE MA copolymer is hydrolyzed and neutralized in an aqueous mixture or slurry of one or more divalent and/or monovalent metal bases by heating the copolymer/base mixture to a temperature ranging from about 45°C to about 100°C In either of the above processes, the resulting slurry or solution is transfeπed to shallow stainless steel drying trays and placed in a forced air mechanical convection oven at 60-70°C for a time sufficient to evaporate the reaction medium (water) and remove water from the copolymer (about 18-24 hours) Alternatively, the resulting slurry or solution can be drum-dned at 100° to 200°C with hot steam to evaporate the water content and recover the copolymer m the flake form After drying, the
