Denture adhesive compositions

本发明涉及一种假牙粘合剂组合物，它含有烷基乙烯基醚-马来酸或酐共聚物和/或含异丁烯的三元共聚物的混合盐，其中该混合盐含有阳离子盐官能，含有至少约1％锶阳离子、约1-40％锌阳离子、0-约2.5％选自铁、硼、铝、钒、铬、锰、镍、铜、钇、钛及其混合物的阳离子，约36-60％游离酸成分和0-约65％选自镁、钙及其混合物的阳离子。另外，本发明还涉及含有上述组合物和至少一种非粘合剂自承性层的假牙粘合剂组合物。本发明涉及通过将上述组合物施加到假牙上、直接施加到口腔、口腔的腭或牙脊、或施加到两者上，之后将假牙固定到口腔的腭或牙脊上，来提高假牙与口腔的粘合性的方法。 The present invention relates to a denture adhesive composition comprising mixed salts of an alkyl vinyl ehter-maleic acid or anhydride copolymer and/or terpolymer with isobutylene wherein the mixed salt contains a cationic salt function comprising at least about 1 % strontium cations, from about 1 % to about 40 % of 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 36 % to about 60 % free acid component; and from 0 % to about 65 % of a cation selected from the group consisting of magnesium, calcium, and mixtures thereof. 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.
