Condensation-crosslinking two-component dental molding materials based on polyethers are particularly suitable for taking impressions. Such materials are used in dental medicine, for example for taking tooth impressions, for bite registration, or for lining dental prostheses. The molding material is made of the following: a) at least one hydroxylsilyl-functional polyether; b) at least one alkoxysilane b.sub.1) or one polysilicic acid ester b.sub.2); c) at least one reinforcing filler c.sub.1) having a BET surface of at least 50 m.sup.2/g or at least one non-reinforcing filler c.sub.2) having a BET surface of less than 50 m.sup.2/g, d) water, if necessary; and e) at least one condensation catalyst.
