Method And Device For Manufacturing And Controlling The Conformity Of A Dental Prosthesis From Parameters Obtained With A Shade Selecting Device

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.

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...

Problems solved by technology

This is where the problems arise because it is necessary to determine parameters, not only subjectively, but also through actual, repeatable and verifiable measurements.

Poor workmanship results in significant costs because it entails:discovering the defect intra-orally, which incurs expenses because it requires an unnecessary trip for the client and unnecessary work for the practitioner,manufacturing a new prosthesis resulting in a delay and associated cost,sending said new prosthesis also resulting in a delay and associated cost,asking the client to come back, andworking to seat the new prosthesis, which requires time a
