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.
