Dental model and its production and use thereof

摘要

Dental modeling material comprises one or more metals and/or metal compounds that expand upon reaction with one another or with other reactants, and a thermoplastic or waxy material. Independent claims are also included for: (1) production of the modeling material by mixing a first component comprising the metal(s) and/or metal compound(s) and optionally a glass ceramic, glass or oxide ceramic material with a second component comprising a wax and optionally additives; (2) production of a dental model by introducing the modeling material into a negative mold of a tooth preparation or prosthetic component and initiating a chemical reaction to expand the material.
