For producing a mother matrix mouldof a full or partial dental prosthesis orof a temporary crown or bridgeor of a permanent crown or bridge,the data of a digitalised virtual model reflecting the status of the jaw is used to generate a data setof the digital tooth set-up of the full or partial dental prosthesis orof the temporary crown or bridge orof the permanent crown or bridge,based on which a rapid manufacturing or rapid prototyping method is used to produce a functional model of the full or partial dental prosthesis or of the temporary crown or bridge or of the permanent crown or bridge that is then invested in a curable elastic impression material from which the mother matrix mould is produced after curing the elastic impression material.
