Storage- and dimensionally stable dental dual-component, elastomeric impression material comprises an addition-crosslinking silicone, where at least one component comprises a polymerization catalyst comprising (a) at least one polydimethylsiloxane comprising polyatomic crosslinkable groups, (b) at least one polyalkylsiloxane with silicon-hydrogen functionality, (c) at least one catalyst, (d) at least one filler, and (e) a combination of separating agent comprising (i) at least one alkyl substituted polydimethylsiloxane, and/or at least one polydimethylsiloxane, and (ii) at least one paraffin. Storage- and dimensionally stable dental dual-component, elastomeric impression material comprises an addition-crosslinking silicone, where at least one component comprises a polymerization catalyst comprising (a) at least one polydimethylsiloxane comprising polyatomic crosslinkable groups, preferably unsaturated crosslinkable groups, (b) at least one polyalkylsiloxane with silicon-hydrogen functionality, (c) at least one catalyst for the reaction of polydimethylsiloxane comprising polyatomic crosslinkable groups with polydimethylsiloxane comprising silicon-hydrogen functionality (d) at least one filler, and (e) a combination of separating agent comprising (i) at least one alkyl substituted polydimethylsiloxane, in which the alkyl chain is linear or branched, and/or at least one polydimethylsiloxane, in which the alkyl chain is linear or branched and partially or fully halogenated, preferably fluorinated, and (ii) at least one paraffin. The composition in the mixed state exhibits a certain consistency according to ISO 4823of = 35 mm. Independent claims are also included for: (1) a dental impression prepared by crosslinking of the storable- and dimensionally stable dental, dual-component, elastomeric impression material; (2) a dental kit comprising the elastomeric impression material, at least one mixing tip, optionally impression tray or optionally material for the production of an individual impression tray, optionally a light-weight, medium or heavy running correction impression material, or elastomeric impression material, at least one scoop, optionally impression tray or optionally material for the production of an individual impression tray, optionally a light-weight, medium or heavy running correction impression material, and optionally a mixing block; and (3) producing the dental impression, comprising providing the storage- and dimensionally stable dental, dual-component, elastomeric impression material, providing a suitable molding, filling the molding with the elastomeric impression material, positioning the filled molding into the patient's mouth, curing the elastomeric impression material, removing the impression obtained from the patient's mouth, and optionally pruning, trimming or processing the obtained impression. |
