Embodiment II

[0057] weight / g)

[0058] Weigh, mix red dye, petroleum jelly and mineral oil in a glass bottle and heat at 50-60°C until visually uniform. . Next, weigh and vibrate the mixed powder (colloidal silica, CMC, AVE / MA copolymer mixed salt or AVE / MA / IB mixed salt) in the container. Then, use a spatula to mix the powder into the liquid until you see an even pink cream. The above cream can be modified by increasing or decreasing the amount of AVE / MA mixed salt or AVE / MA / IB mixed salt by 0-18.75 grams, petrolatum by 0-18.75 grams and / or CMC by 0-18.75 grams sex. The above cream composition can also be modified by using a mixture of different AVE / MA polymer mixed salts and / or AVE / MA / IB mixed salts. The subject applied 0.1-2 grams of the cream composition to the dentures. The subjects then place the dentures in their mouths and press them into place.

Embodiment III

[0060] weight / g)

[0061] All ingredients are mixed. The above composition can be modified by increasing or decreasing the amount of AVE / MA mixed salt or AVE / MA / IB polymer mixed salt by 0-50 grams, and / or increasing or decreasing CMC by 0-40 grams. The powder compositions described above can also be modified by using mixtures of different AVE / MA mixed salts and / or AVE / MA / IB mixed salts. The subject applied 0.1-2 grams of the composition to the pre-moistened denture and allowed it to briefly hydrate. The subjects then place the dentures in their mouths and press them into place.

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.

Description

background of the invention [0001] Typically removable dentures, dental plates, etc. consist of teeth secured in a suitable plate or base. Denture stabilizers are used to fill the gap between the denture and the gum or tissue. Before the denture is placed in the mouth, the denture stabilizer is placed on the surface of the denture board, it should evenly contact the gums and mucous tissue for a good fit. Denture stabilizers are not only formulated to be adhesive, but also to provide a lining or cushion between the denture and the gums or tissues, thereby holding the denture securely in place in the oral cavity. [0002] Over the years, considerable efforts have been made to develop improved denture adhesive compositions. Synthetic and natural polymers and gums have been used alone or in combination, and in combination with various adhesives and other materials to overcome certain deficiencies. These deficiencies include insufficient retention, adhesive seeping from under th...
