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, 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...

AI Technical Summary

Benefits of technology

The text is explaining that when selecting the shade for a patient's tooth, it is important to consider only the interactions of adjacent teeth. This helps to overcome the impact of the entire environment around the tooth. The technical effect of this is that it allows for more accurate and precise shade selection for dental procedures.

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 and is therefore costly, not counting the time spent to exchange information and the negative impact on the reputation of the practitioner.

The first difficulty is precisely the shade selection.

This measurement technique is unreliable.

However, this device can only make spot measurements on the tooth.

Although it can perform a two-dimensional measurement, this device has a relatively bulky measuring head.

Another drawback of these known devices is related to the fact that the measuring head remains stationary relative to the handle.

Therefore, the use of these devices is limited to a front portion of the patient's dental arch.
