Condensation-crosslinking two-component dental molding materials based on polyethers, which are particularly suitable for taking impressions, as well as mixtures that can be obtained from them, and their use. Such materials are used in dental medicine, for example for taking tooth impressions, for bite registration, or for lining dental prostheses. The material contains the following: at least one alkoxysilyl-functional polyether a), at least one reinforcing filler b.sub.1) having a BET surface of at least 50 m.sup.2/g or at least one non-reinforcing filler b.sub.2) having a BET surface of less than 50 m.sup.2/g, water c), if applicable, at least one condensation catalyst d), and a hydroxylsilyl-functional polyether e).
