Abstract

A virtual model of an intraoral cavity is provided, wherein this process is initialized by a dental clinic, and the design and manufacture of a suitable dental prosthesis for the intraoral cavity is shared between a dental lab and a service center.

First claim

What is claimed is:

1. A method for manufacturing an orthodontic dental appliance, comprising:
receiving, at a service center from a dental clinic, three-dimensional data indicative of a patient's oral cavity and a final position of at least one tooth, wherein the service center is at a first geographic location, and wherein the dental clinic is at a second geographic location remote from the first geographic location;
generating, at the service center, a three-dimensional digital dentition model based on the three-dimensional data;
using, at the service center and based on user input from a user at the service center, the three-dimensional digital dentition model to move the at least one tooth of the three-dimensional digital dentition model towards the final position;
outputting, from the service center, information for manufacturing the orthodontic dental appliance based on the movement of the at least one tooth of the three-dimensional digital dentition model towards the final position;
receiving, at a dental lab, the information for manufacturing the orthodontic dental appliance, wherein the dental lab is at a third geographic location remote from both the first geographic location and the second geographic location; and
manufacturing the orthodontic dental appliance based on the information.

2. The method of claim 1 , further comprising:
providing the orthodontic dental appliance to the dental clinic for treatment of teeth of the patient.

3. The method of claim 1 , further comprising:
receiving, at the service center, an orthodontic prescription from the dental clinic.

4. The method of claim 3 , wherein the orthodontic prescription includes a specification of teeth that are to be moved in an orthodontic dental treatment.

5. The method of claim 4 , wherein the orthodontic prescription includes a final position of the teeth at the conclusion of the orthodontic dental treatment, including the final position of the at least one tooth.

6. The method of claim 1 , wherein generating the three-dimensional digital dentition model includes identifying an external surface shape geometry of a dentition.

7. The method of claim 1 , wherein using, at the service center, the three-dimensional digital dentition model to move the at least one tooth of the three-dimensional digital dentition model towards the final position includes applying a virtual model of the orthodontic dental appliance to the three-dimensional digital dentition model.

8. The method of claim 7 , further comprising:
simulating the movement of teeth that would occur in an orthodontic dental treatment using the virtual model of the orthodontic dental appliance.

9. The method of claim 1 , wherein manufacturing the orthodontic dental appliance is shared by the service center and the dental lab.

10. A service center system comprising computer hardware, the computer hardware programmed to:
receive, from a dental clinic, three-dimensional data indicative of a patient's oral cavity and a final position of at least one tooth, wherein the service center system is at a first geographic location, and wherein the dental clinic is at a second geographic location remote from the first geographic location;
generate a three-dimensional digital dentition model based on the three-dimensional data;
use the three-dimensional digital dentition model to move the at least one tooth of the three-dimensional digital dentition model towards the final position based on user input from a user at the service center system;
output information for manufacturing an orthodontic dental appliance customized to treat a dentition of the patient based on the movement of the at least one tooth of the three-dimensional digital dentition model towards the final position, and
transmitting, to a dental lab, the information for manufacturing the orthodontic dental appliance, wherein the dental lab is at a third geographic location remote from both the first geographic location and second geographic location.

11. The service center system of claim 10 , wherein the computer hardware is further programmed to:
receive an orthodontic prescription from the dental clinic.

12. The service center system of claim 11 , wherein the orthodontic prescription includes a specification of teeth that are to be moved in a dental treatment.

13. The service center system of claim 12 , wherein the orthodontic prescription includes a final position of the teeth at the conclusion of the dental treatment, including the final position of the at least one tooth.

14. The service center system of claim 10 , wherein the computer hardware generates the three-dimensional digital dentition model by identifying an external surface shape geometry of a dentition.

15. The service center system of claim 10 , wherein the computer hardware uses the three-dimensional digital dentition model to move the at least one tooth of the three-dimensional digital dentition model towards the final position by applying a virtual model of the orthodontic dental appliance to the three-dimensional digital dentition model.

16. The service center system of claim 15 , wherein the computer hardware is further programmed to:
simulate the movement of teeth that would occur in the dental treatment using the virtual model of the orthodontic dental appliance.

17. A method for manufacturing orthodontic dental appliances customized for treating a dentition of a patient, the method comprising:
receiving, at a dental service center from a dental clinic, three-dimensional digital data indicative of the dentition of the patient from the dental clinic, wherein the dental service center is at a first geographic location, and wherein the dental clinic is at a second geographic location remote from the first geographic location;
receiving, at the dental service center, a prescription from the dental clinic;
generating, at the dental service center, a three-dimensional computer model of the dentition of the patient based on the three-dimensional digital data received from the dental clinic;
manipulating, at the dental service center, the three-dimensional computer model of the dentition of the patient to execute an orthodontic treatment specified by the prescription received from the dental clinic based on user input from a user at the dental service center;
simulating, at the dental service center, movement of the dentition of the patient that would occur in the specified orthodontic treatment;
sending, from the dental service center, information for manufacturing the orthodontic dental appliances that are customized for treating the dentition of the patient;
receiving, at a dental lab, the information for manufacturing the orthodontic dental appliances, wherein the dental lab is at a third geographic location remote from both the first geographic location and the second geographic location; and
manufacturing the orthodontic dental appliances based on the information.

18. The method of claim 17 , wherein the received three-dimensional digital data indicative of the dentition of the patient comprises data acquired by scanning the dentition of the patient directly or data acquired from scanning a physical model of the dentition.

19. The method of claim 17 , further comprising receiving, from a dentist of the dental clinic, a specification of the dental lab to which the information for manufacturing the orthodontic dental appliances is to be sent.

20. The method of claim 17 , wherein manufacturing the orthodontic dental appliances is shared by the dent
