Abstract
A process for producing artificial teeth or parts thereof is given, in which a mass of at least one polyfunctional isocyanate, at least one polyol and at least one methacrylate monomer, as well as in each case one catalyst for the polymerization of the methacrylate monomer and for the acceleration of the formation of a urethane is hardened in a first stage to an elastic blank, which can then be cured in a second stage to artificial teeth or parts thereof. A storage-stable dental material for performing the process comprises two components, namely at least one polyfunctional isocyanate as the first component and the remaining constituents as the second component.
