The value of n should be such that the polymer has a viscosity at 25° C. of between 200 and 200,000 mPa.s, preferably 1,000 to 10,000 mPa.s. no filling with gypsum several times is possible. 19.4 parts of a polydimethylsiloxane with terminal vinyl groups and a viscosity of 7,000 mPa.s at 23° C., 3.1 parts of a polydimethylsiloxane containing SiH groups and with a viscosity of 60 mPa.s at 23° C., 32.2 parts of a polydimethylsiloxane with a viscosity of 50 mPa.s at 23° C., 0.3 part of a silanized pyrogenic silicic acid, 44 parts of calcined kieselguhr (1 to 20 μm), 0.3 part of inorganic coloured pigment dispersed in 0.2 part of a polydimethylsiloxane with a viscosity of 50 mPa.s at 23° C. and 0.6 part of a carbosilane surfactant hydrophilizing agent according to WO 96/08230, preparation example 2, are combined in a kneader by mixing to give a homogeneous base paste. Silicone, being a more elastic material, allows for more uses for dentists than alginate. The hydrocarbon radicals can be methyl, ethyl, C2 -C10 -aliphatics, trifluoropropyl groups and aromatic C6 -C12 substituents. Various additives which increase the hydrophilicity of silicone impression compositions have been described in the literature to solve this problem. The amount of material retained in the mixing tip is slightly greater than that used in static mixing. This organopolysiloxane preferably contains from 0.01 to 1.7 wt. The recipes according to the invention are particularly suitable for mechanical mixing in automatic mixing apparatuses (e.g. Elastomeric materials include polysulfide, polyether, condensation-cured silicone, and addition-cured silicone. %, based on the total weight of the cured composition, and the composition has a Shore hardness A to be determined in accordance with DIN 53505, of less than 45--measured after 30 minutes--, and a viscosity, determined in accordance with ISO 4823, of 31 to 39 mm. % platinum in a polydimethylsiloxane with terminal vinyl groups and a viscosity of 2,000 mPa.s at 23° C. 50 g base paste and 10 g catalyst paste are mixed completely. When producing the provisional crowns and bridges, the dentist must cut the cured impression at the interdental points, so that the material used for production of the provisional prostheses, which in itself is relatively brittle, does not become too thin at the interdental points and break. Therefore, recently, addition silicones have been labeled as hydrophilic due to extrinsic surfactant addition, improving oral tissue and gypsum wettability when the impression and cast pouring are performed. Classification of Elastomeric Impression materials: Till now the elastomeric impression materials are divided into 3 types based on the material used Mach-2 Die Impression Material Silicone Refill Flowable 30 Second Set 2/Package %, as a rule no noticeable influence on the ability to stand is detectable, and amounts of >10 wt. in DE-A-43 06 997, page 5, reference being made to this. The crown and bridge material cured in the patient's mouth to give the provisional prosthesis is likewise difficult to separate from the impression material if this has too high a hardness. Preferred reinforcing fillers are pyrogenically prepared highly disperse silicic acids, which have preferably been hydrophobized by a surface treatment. The viscosity according to ISO 4823 is determined as 36 mm. The Shore hardness A after 30 minutes is 35. Used in other industries more elastic material, allows for more uses dentists.
