1. A method of planning orthodontic treatment of a patient comprising use of incremental tooth repositioning appliances, the method comprising:
receiving an initial digital data set representing an initial arrangement of the patient's teeth;
producing a final digital data set representing the patient's teeth in a desired or prescribed arrangement;
producing a plurality of intermediate digital data sets representing intermediate arrangements of the patient's teeth, wherein at least some of the intermediate tooth arrangements represent different orthodontic treatment stages as the patient's teeth are moved from the initial arrangement toward the final arrangement.
2. The method of claim 1, wherein the initial digital data set is generated from a scan of the patient's teeth of impression thereof.
3. The method of claim 1, wherein the intermediate digital data sets for different orthodontic treatment stages are configured for facilitating fabrication of shell appliances for a corresponding treatment stage.
4. The method of claim 1, wherein the appliances are generated based on at least some of the intermediate digital data sets and wherein the plurality of intermediate digital data sets are produced prior to successively applying appliances to the patient's teeth.
5. The method of claim 1, further comprising providing a plurality of the intermediate digital data sets to a fabrication operation for fabrication of a series of successive tooth repositioning appliances.
6. The method of claim 5, wherein the providing comprises transmitting the digital data sets over a network to the remote location comprising a fabrication machine.
7. An orthodontic treatment plan for repositioning a patient's teeth using incremental tooth repositioning appliances, the treatment plan residing on a computer readable storage media and comprising a plurality of intermediate digital data sets representing intermediate arrangements of the patient's teeth, wherein at least some of the intermediate tooth arrangements represent different orthodontic treatment stages as the patient's teeth are moved from an initial arrangement toward a final arrangement representing the patient's teeth in a desired or prescribed arrangement.
8. The orthodontic treatment plan of claim 7, wherein the intermediate digital data sets for different orthodontic treatment stages are configured for facilitating fabrication of shell appliances for a corresponding treatment stage.
9. The orthodontic treatment plan of claim 8, wherein the shell appliances comprise a plurality of successive appliances having teeth receiving cavities, and wherein cavities of at least two successive appliances have different geometries shaped to receive and reposition the patient's teeth.
10. A method for generating appliances for repositioning a patient's teeth, comprising:
receiving an orthodontic treatment plan for repositioning a patient's, the treatment plan comprising a plurality of intermediate digital data sets representing intermediate arrangements of the patient's teeth, wherein at least some of the intermediate tooth arrangements represent different orthodontic treatment stages as the patient's teeth are moved from an initial arrangement toward a final arrangement representing the patient's teeth in a desired or prescribed arrangement;
generating a patient removable appliance for each of at least two of the intermediate arrangements, each patient removable appliance having cavities and wherein the cavities of appliances for the at least two intermediate arrangements have different geometries shaped to receive and resiliently reposition teeth from one arrangement to a successive arrangement.
11. The method of claim 10, wherein the patient removable appliances for each of the at least two intermediate arrangements are generated prior to successively applying the appliances to the patient's teeth.
12. The method of claim 10, wherein the orthodontic treatment plan is transmitted from a remote location.
13. An improved method for repositioning teeth using a plurality of appliances comprising polymeric shells having teeth receiving cavities shaped to receive and resiliently reposition a patient's teeth, wherein an improvement comprises modeling prior to a stage of treatment a plurality of different teeth-receiving cavity geometries for at least three appliances that when worn successively by the patient reposition the patient's teeth toward a final tooth arrangement, the at least three appliances comprising at least two successive intermediate appliances having different cavity geometries, and wherein said stage of treatment comprises successively applying any of the at least three appliances to the patient's teeth, wherein each of the different teeth-receiving cavity geometries for the at least three appliances correspond to different arrangements of teeth.
14. The method of claim 13, wherein the successive intermediate appliances are immediately successive.
15. The method of claim 13, wherein the modeling occurs before fabricating at least some of the appliances.
16. The method of claim 13, further comprising fabricating the at least two successive intermediate appliances after modeling the cavity geometries for at the at least three appliances.
17. A system for repositioning teeth a patient's teeth, comprising a plurality of incremental position adjustment appliances configured for delivery to the patient prior to a stage of treatment, the plurality of appliances comprising a patient removable appliance for each of at least two different intermediate arrangements for repositioning the patient's teeth toward a final position, each patient removable appliance having teeth receiving cavities and wherein the cavities of two different successive appliances of the plurality have different geometries corresponding to different arrangements of teeth and shaped to receive and resiliently reposition teeth from one arrangement to a successive arrangement, wherein said stage of treatment comprises successively applying the appliances to the patient's teeth.
