Abstract

Embodiments of the present disclosure create an “exchange” where dentists who invest in on-site restoration technologies can share their restoration design, restoration supplies, characterization knowledge, and idle milling time with local dentists. Suppliers can further offer quality control by double checking designs and selections. The platform of shade measurements, block selections, and characterization recommendations further serves as a resource to the dental community at large for improving shade matching in dentistry restorations.

Claims (36)

1. A shade matching server device comprising:

one or more processors;

one or more communications interfaces;

memory containing instructions executable by the one or more processors with the one or more communications interfaces whereby the server device is operable to:

receive a stereo lithic file and a shade measurement for a design of a restoration for a target patient from a requesting computing device:

receive a geographic area designation from the requesting computing device;

receive inventory information from a plurality of supplying computing devices;

generate one or more material recommendations for the restoration for the target patient based on inventory information from a plurality of supplying computing devices that match the geographic area designation, wherein the material recommendations comprise recommendations for computer aided design and computer aided manufacturing blocks of different materials;

receive stereo lithic files and shade measurements for restorations for other patients from supplying computing devices;

invoke a machine learning process with the stereo lithic file and shade measurement for the restoration for the target patient;

generate one or more characterization recommendations for the restoration for the target patient based on machine learning and statistical models; and

send the one or more material recommendations and the one or more characterization recommendations for the restoration for the target patient to the requesting computing device, wherein the one or more characterization recommendations includes one or more staining recommendations and wherein the one or more characterization recommendations include a custom map identifying spatial information for aligning the one or more staining recommendations to the restoration for the target patient after the restoration has been milled from the one or more material recommendations.

2. The server device of claim 1 , wherein applying the machine learning process involves applying a translation process to the stereo lithic file for the restoration of the target patient and the stereo lithic files for the restorations for other patients.

3. The server device of claim 1 , wherein the one or more characterization recommendations includes one or more glazing recommendations.

4. The server device of claim 1 , wherein the one or more characterization recommendations includes information for using the spatial information of the one or more characterization recommendations in an augmented reality application.

5. The server device of claim 1 , wherein the server device is further operable to:

rank order the one or more material recommendations.

6. The server device of claim 1 , wherein the server device is further operable to:

rank order the one or more characterization recommendations.

7. The server device of claim 6 , wherein the one or more material recommendations are rank ordered by one of the methods in the group comprising of: the shade of the material that best matches the shade measurement, the cost of the material, the availability of the material, the estimated target delivery time of the material, and the estimated target delivery time of a restoration created from the material.

8. The server device of claim 1 , wherein the geographic area designation is one of the group comprising: a physical address, latitude and longitudinal coordinates, what3words, zip code, point and a radius, and an arbitrary polygon.

9. The server device of claim 1 , wherein the shade measurement comprises individual measurements for chroma, hue, and value.

10. The server device of claim 1 , wherein generating the one or more material recommendations comprises matching the closest values of the individual measurements of chroma, hue, and value for both the shade measurement and the material recommendation.

11. The server device of claim 1 , wherein the shade measurement comprises an aggregate measure of chroma, hue, and value.

12. The server device of claim 1 , wherein generating the one or more material recommendations comprises matching the closest aggregate measure of chroma, hue, and value for both the shade measurement and the material recommendation.

13. The server device of claim 1 , wherein the computer aided design and computer aided manufacturing blocks of different materials are blocks selected from the group of materials comprising: feldspathic porcelain, ceramic resin hybrid, leucite-reinforced porcelain, lithium disilicate, nano ceramic/resin, composite resin, and zirconia reinforced lithium silicate.

14. The server device of claim 1 , wherein the server device is further operable to:

detect a minimum depth error based on the design file and the material recommendation selection; and

request a reduction coping.

15. The server device of claim 1 , wherein the server device is further operable to:

determine if the design file contains identifying information and request the manufacture of a restoration based on the design file; and

receive information indicating the completion of the manufacture of the restoration.

16. The server device of claim 1 , wherein the server device is further operable to:

receive information indicating the completion of the reduction coping and wherein the identifying information is one of the group comprising: information identifying a dentist, a dental office, and a patient;

initiate a delivery request with a delivery service, wherein initiating the delivery request comprises at least one of the group consisting of: receiving delivery information to the requesting computing device and sending delivery information to a delivery service; and

remove identifying information from the design file.
