ABSTRACT:
Dental impression masses are described, which contain selected curable polymer systems and a mixture of a silicon-containing non-ionic surfactant that has at least one (poly)alkylene oxide group and a molecular mass of less than 6000 g/mol, and of a non-ionic fluorosurfactant containing at least one partially fluoridated or perfluoridated hydrocarbon group that is connected with a (poly)alkylene oxide group, a hydrocarbon group, an aliphatic polyhydroxy group, or heterocyclic group that contains nitrogen, by way of an oxygen atom, an amino group, a keto group, a carboxylic acid ester group, a phosphoric acid ester group, a carboxylic acid amide group and/or a phosphoric acid amide group, or of a non-ionic fluorosurfactant that has at least one partially fluoridated or perfluoridated hydrocarbon radical and at least one amino oxide radical. These dental impression masses flow extremely well onto the damp tooth under practical conditions, and an extremely detail-accurate impression forms during the processing time.
