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 performed by a computer system comprising memory and one or more processors, the method comprising:
acquiring motion data for a patient's dentition, wherein the motion data is represented in a three-dimensional (3D) digital coordinate system;
determining a vertical dimension of occlusion in the 3D digital coordinate system for the patient based on:
aligning digital anterior visual data of the patient to a 3D digital model in the 3D digital coordinate system, and
receiving user input indicating the vertical dimension of occlusion based on aligning the digital anterior visual data to the 3D digital model in the 3D digital coordinate system;
positioning the 3D digital model in the 3D digital coordinate system based on the motion data to achieve the desired vertical dimension; and
returning the positioned 3D digital model.
2 . The method of claim 1 , the method further comprising generating a 3D digital denture design based on the positioned 3D digital model.
3 . The method of claim 1 , wherein the vertical dimension of occlusion comprises a distance between corresponding dental features on opposing dental arches when the patient is at rest.
4 . The method of claim 1 , wherein the digital anterior visual data comprises images of the patient.
5 . The method of claim 1 , wherein the digital anterior visual data comprises videos of the patient.
6 . The method of claim 1 , wherein, in response to aligning the digital anterior visual data of the patient to the 3D digital model in the 3D digital coordinate system, the method further comprises:
displaying the aligned anterior visual data of the patient in the 3D digital coordinate system; and
receiving the user input in response to the displaying.
7 . The method of claim 1 , wherein the digital anterior visual data of the patient comprises a digital anterior facial image of the patient.
8 . The method of claim 1 , wherein the 3D digital model comprises a 3D digital model of the particular patient's dentition.
9 . The method of claim 1 , wherein the 3D digital model, the motion data, the vertical dimension of occlusion, and positioning of the 3D digital model is used to automate generation of a 3D digital denture design.
10 . The method of claim 9 , wherein the generated 3D digital denture design comprises removable prostheses, partial prostheses, implant retained prostheses, or hybrid prostheses.
11 . The method of claim 9 , wherein generating the 3D digital denture design comprises assessing the motion data to inform a design of different types of dentures.
12 . The method of claim 11 , wherein assessing the motion data further comprises identifying a location of dental implant in the patient's mouth.
13 . The method of claim 1 , wherein the motion data comprises simulated motion data for the patient.
14 . The method of claim 1 , wherein the motion data comprises inferred motion data for the patient.
15 . The method of claim 1 , wherein the motion data comprises actual motion data captured from the patient.
16 . A system comprising:
a motion capture system configured to capture patient motion and generate patient motion data; and
a denture design system including at least one processor and at least one memory that is operably coupled to the at least one processor and storing instructions that, when executed by the at least one processor, cause the denture design system to:
position an opposing geometric structure in a plurality of positions in a 3D digital coordinate system based on the patient motion data represented in the 3D digital coordinate system; and
join the opposing geometric structure in the plurality of positions to form an occlusal guidance surface.
17 . The system of claim 16 , wherein the denture design system is further configured to: position 3D digital denture library teeth in the 3D digital coordinate system based on the occlusal guidance surface.
