COLOR DIGITAL DENTURE DESIGN AND REPLACEMENT
Apparatuses, components, devices, methods, and systems for generating dentures are provided. An example system includes a motion capture system that captures patient jaw motion and generates patient jaw motion data; and a denture design system that generates a denture design based on the patient jaw motion data. An example method includes acquiring a digital reference denture model of a reference denture; selecting a denture tooth library based on the digital reference denture model; selecting and aligning denture library teeth from the selected denture tooth library to the digital reference denture model; generating a denture base digital model based on the digital reference denture model and the aligned denture library teeth; and fabricating a physical denture based from the denture base digital model.
1 . A method for fabricating dentures, the method comprising:
acquiring a digital reference denture model of a reference denture for a patient;
acquiring color data for the digital reference denture model;
selecting a denture tooth library based on the digital reference denture model;
selecting and aligning denture library teeth from the selected denture tooth library to the digital reference denture model;
generating a denture base digital model based on the digital reference denture model and the aligned denture library teeth;
assigning colors to the denture base digital model and the aligned denture library teeth; and
fabricating a physical denture from the denture base digital model and the aligned denture library teeth using a rapid fabrication system with multiple colors.
2 . The method of claim 1 , wherein:
the colors are assigned to the denture base digital model based on the color data acquired for the digital reference denture model, and
fabrication of the physical denture by the rapid fabrication system is performed by applying the colors assigned to the denture base digital model using the multiple colors of the rapid fabrication system.
3 . The method of claim 2 , wherein:
the denture base digital model comprises a 3D mesh including polygons defined by vertices, and
the color data is associated with at least some portions of the 3D mesh.
4 . The method of claim 3 , wherein the color data is associated with at least some of the polygons included in the 3D mesh.
5 . The method of claim 3 , wherein the color data is associated with at least some of the vertices included in the 3D mesh.
6 . The method of claim 2 , wherein:
the denture base digital model comprises a plurality of voxels, and
the color data is associated with the plurality of voxels.
7 . The method of claim 6 , wherein the colors are assigned to the denture base digital model are determined based on blending of the color data associated with the plurality of voxels.
8 . The method of claim 2 , wherein the color data is applied to and stored in association with the digital reference denture model based on a color 3D scan or one or more photographs of a reference denture that is being replaced by the physical denture that is being fabricated.
9 . The method of claim 8 , wherein acquiring the color data comprises texture mapping colors from the color 3D scan or the one or more photographs onto a surface of the reference denture.
10 . The method of claim 8 , wherein acquiring the color data comprises mapping colors from the color 3D scan or the one or more photographs of the reference denture onto corresponding portions of the digital reference denture model.
11 . The method of claim 8 , wherein acquiring the color data comprises:
mapping colors from the color 3D scan or the one or more photographs onto a surface of the reference denture;
identifying damaged portions and undamaged portions of the reference denture;
discarding a portion of the colors mapped onto damaged portions of the reference denture; and
mapping remaining portions of the colors mapped onto undamaged portions of the reference denture onto the digital reference denture model.
12 . The method of claim 11 , wherein the damaged portions of the reference denture are identified based on features, shapes, or other comparisons to one or more denture library teeth.
13 . The method of claim 2 , wherein the color data is acquired for one or more denture library teeth that are represented by the digital reference denture model.
14 . The method of claim 13 , wherein color data is selected from among multiple versions of the one or more denture library teeth that each have different color shading.
15 . The method of claim 14 , wherein the color data is selected based on user input identifying shading preferences of the patient for whom the physical denture is being fabricated.
16 . The method of claim 14 , wherein the color data is selected based on shading information identified from analysis of reference dentition of the patient.
17 . The method of claim 16 , wherein the color data is selected based on a closest match from among the multiple versions of the one or more denture library teeth with the shading information for the reference dentition of the patient.
18 . The method of claim 16 , wherein the reference dentition comprises a reference denture that is being replaced for the patient by the physical denture that is being fabricated.
19 . The method of claim 16 , wherein the reference dentition comprises one or more teeth of the patient that are being replaced for the patient by the physical denture that is being fabricated.
