Abstract
Orthodontic devices such as aligners, palatal expanders, retainers, and dental implants can be used to adjust the position of teeth and to treat various dental irregularities. To help the clinician or doctor (i.e., orthodontist) design and plan the subject's treatment plan, a 3D digital model of the subject's teeth, dentition, and gingiva can be constructed from a 3D scan of the subject's mouth, teeth, dentition, and gingiva. The 3D model of the subject's teeth and dentition can be displayed graphically to the doctor on a display using a computing system with memory and software.
Claims23
A method, the method comprising:
- displaying, on a display, a first three dimensional (3D) model of a subject's dentition that shows an arrangement of the subject's teeth before receiving a treatment, and a second 3D model that shows an arrangement of the subject's teeth subject to a first orthodontic treatment;
- wherein the second 3D model is displayed at either a final stage or an intermediate treatment stage of the first orthodontic treatment;
- adjusting a view of both of the first 3D model and the second 3D model based on a user input modifying a view of one of the first 3D model or the second 3D model;
- switching the view of both the first 3D model and the second 3D model to an occlusal view when the user selects a control, wherein the occlusal view shows occlusal surfaces of teeth in the first 3D model and the second 3D model, further wherein the occlusal view indicates one or more regions of inter-arch collisions on either or both of the first 3D model and the second 3D model.
A method, the method comprising:
- displaying, on a display, a first three dimensional (3D) model of a subject's dentition that shows an arrangement of the subject's teeth before receiving a treatment, and a second 3D model that shows an arrangement of the subject's teeth subject to a first orthodontic treatment;
- wherein the second 3D model is displayed at either a final stage or an intermediate treatment stage of the first orthodontic treatment;
- adjusting a view of both of the first 3D model and the second 3D model based on a user input modifying a view of one of the first 3D model or the second 3D model, wherein adjusting the view comprises adjusting one or more of the rotation, zoom and pan;
- switching the view of both the first 3D model and the second 3D model to an occlusal view when the user selects a control, wherein the occlusal view shows occlusal surfaces of teeth in the first 3D model and the second 3D model, further wherein the occlusal view indicates one or more regions of inter-arch collisions on either or both of the first 3D model and the second 3D model, using an indicator that is scaled to differentiate a relative degree of contact between an upper arch and a lower arch.
A system for visualizing a subject's teeth, the system comprising:
- one or more processors;
- a memory coupled to the one or more processors, the memory configured to store computer-program instructions, that, when executed by the one or more processors, perform a computer-implemented method comprising:
- displaying, on a display, a first three dimensional (3D) model of a subject's dentition that shows an arrangement of the subject's teeth before receiving a treatment, and a second 3D model that shows an arrangement of the subject's teeth subject to a first orthodontic treatment;
- wherein the second 3D model is displayed at either a final stage or an intermediate treatment stage of the first orthodontic treatment;
- adjusting a view of both of the first 3D model and the second 3D model based on a user input modifying a view of one of the first 3D model or the second 3D model;
- switching the view of both the first 3D model and the second 3D model to an occlusal view when the user selects a control, wherein the occlusal view shows occlusal surfaces of teeth in the first 3D model and the second 3D model, further wherein the occlusal view indicates one or more regions of inter-arch collisions on either or both of the first 3D model and the second 3D model.
