Abstract
The present invention relates to a method for the fabrication of a dental cast part having the following steps: Forming and hardening a first working model of a dentition, in such a way that the material used for fabrication of the working model expands during hardening; modelling a restoration from a modelling material on the first working model or a second working model that is essentially identical to the first working model in respect of its dimensions; embedding the restoration model in a settable dental investment that is at least essentially quartz-free; hardening the dental investment; removing the restoration model from the dental investment so that a casting form is created; introducing liquid metal into the casting form and allowing the metal to solidify in the casting form; removal of the metal that has solidified to form a dental cast part.
