The invention is intended for a manufacturing process of coated working models for the production of dental prostheses using a "digital workflow" comprising:- scanning the patients mouth to obtain a digital file containing the patients scanned mouth- processing using a computer-aided design and computer-aided manufacturing system (CAD/CAM) of this digital file in order to generate the necessary information to produce a model using a computer numerical control device (CNC)- mixing the powder/liquid components of a coating for dental use and pouring and setting this mixture in a suitable mould, thereby producing a coating product and- processing the coating product in the CNC device using the information generated during the CAD/CAM process.
