A method for manufacturing and controlling the conformity of a dental prosthesis from parameters obtained intra-orally with a shade selecting device is described herein. The method includes:selecting the shade of the client tooth to be replaced or restored by the practitioner using the practitioner's shade selecting DPraticien device, with local storage of such data,transmitting these data to a practitioner's computer station equipped with software for visualizing the measurement data and possibly with software for entering the client's contact information and specific data, both software programs being advantageously combined,transmitting these data to a dental technician's computer station,manufacturing by the dental technician of the prosthesis according to the data received from the practitioner,controlling the prosthesis data using a dental technician's shade selecting DProthésiste device, self-calibrated in the same way as the DPraticien device, andsending the prosthesis to the practitioner.
