Abstract: A device for tooth shade measurement comprising a housing, a handle and a measuring head, characterized in that said measuring head includes a hollow body extending along a longitudinal axis, said hollow body comprising a proximal end, a bent distal end relative to the longitudinal axis, said distal end being provided with a removable tip designed to come into contact with a tooth surface to be analyzed, at least one light source and image acquisition means, integral with the hollow body, said hollow body being adapted to transmit the light from said light source from the proximal end up to the distal end, and in that said device comprises an orientation assembly for mounting the proximal end of the hollow body in the housing so that the measuring head occupies different angular positions relative to the housing.

Abstract: 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, and sending the prosthesis to the practitioner.
