Disclosed are dental impression materials containing selected curable polymer systems and a mixture of nonionic surfactant which is provided with silicon and at least one (poly)alkylene oxide radical while having a relative molar mass of less than 6000 g/mol, and a nonionic fluorinated surfactant containing at least one partially fluorinated or perfluorinated hydrocarbon radical that is bonded to a (poly)alkylene oxide radical, carbohydrate radical, aliphatic polyhydroxy radical, or heterocyclic radical containing nitrogen via an oxygen atom, amino group, keto group, carboxylic acid ester group, phosphoric acid ester group, carboxylic acid amide group, and/or phosphoric acid amide group, or a nonionic fluorinated surfactant containing at least one partially fluorinated or perfluorinated hydrocarbon radical and at least one amine oxide radical. The inventive dental impression materials flow extraordinarily well to the moist tooth in conditions prevailing in a dentist's office while an extremely detailed and accurate impression is created during the processing time. |
