Abstract: A modeling material for dental purposes comprises at least one metal and/or at least one metal compound which are able to react chemically with one another and/or with at least one further reactant so as to lead to an increase in volume, and at least one substance having thermoplastic and/or wax-like properties. If desired, a glass-ceramic, a glass and/or an oxide-ceramic material and, if desired, an additive, in particular a dispersant, can additionally be present. The modeling material is particularly suitable for compensating for the sintering shrinkage which occurs in the production of ceramic shaped dental parts.
