Embodiment Construction

[0039]FIG. 1 shows in 1 a measuring device for acquiring a color image of a tooth or the spectral data of a tooth. These measures allow achieving a complete and precise mapping of the variations in the different characteristics of the tooth. In particular, this mapping allows determining the tooth shade for the realization of a dental prosthesis according to the method of the present invention.

[0040]The device comprises a gripping handle 10 topped by a housing 11, one end of the housing 11 being provided with a measuring head 20 for acquiring spectral data or images.

[0041]According to one embodiment, the housing 11 has a substantially parallelepipedic shape with an upper face 14 comprising a display 15 which is used to indicate in real time the data relating to the analyzed tooth generated by the measuring head 20.

[0042]These data can then be transmitted to the computer means of the user by Wi-Fi connection or through a USB connection to be processed by a calculation software for pr...

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, andsending the prosthesis to the practitioner.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a method and a device for manufacturing and controlling the conformity of a dental prosthesis from parameters taken intra-orally with a shade selecting device.[0002]We know that the manufacture of dental prostheses is performed by dental technicians who are not necessarily in the vicinity of the dental practitioner's office, and can even take place in industrially oriented units in countries which are geographically quite distant from the site where they will be seated but whose labor costs are lower.[0003]The prosthesis thus remotely manufactured is sent by courier to the dental practitioner and it is necessary to deliver a prosthesis that is not only dimensionally accurate, this not being the object of the present invention, but also aesthetically perfect. It is indeed essential for a prosthesis: to be natural to the point that it is not noticed and fits perfectly. The shade in the broad sense is therefore paramount...
