1. A method of generating shell appliances configured to resiliently reposition a patient'"'"'s teeth, the method comprising:
- receiving a first digital data set representing a first arrangement of the patient'"'"'s teeth;
generating a final position digital data set representing the patient'"'"'s teeth in a desired or prescribed final arrangement;
generating a plurality of intermediate digital data sets representing different 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 first arrangement toward the final arrangement; and
after generating the plurality of intermediate digital data sets, generating a plurality of shell appliances based on the plurality of intermediate digital data sets, the plurality of shell appliances each having cavities shaped to receive and resiliently reposition teeth along respective movement paths for the teeth between the first arrangement and the final arrangement.

17. A method of generating shell appliances configured to resiliently reposition a patient'"'"'s teeth, the method comprising:
-
receiving a first digital data set representing a first arrangement of the patient'"'"'s teeth; segmenting the first digital data set into a plurality of manipulable tooth components; generating a plurality of intermediate digital data sets based on the plurality of manipulable tooth components, the plurality of intermediate digital data sets representing different 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 first arrangement toward a final arrangement; and generating a plurality of shell appliances based on the plurality of intermediate digital data sets after generating the plurality of intermediate digital data sets, the plurality of shell appliances each having cavities shaped to receive and resiliently reposition teeth along respective movement paths for the teeth between the first arrangement and the final arrangement. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A method of generating shell appliances configured to resiliently reposition a patient'"'"'s teeth, the method comprising:
-
receiving a first digital data set representing a first arrangement of the patient'"'"'s teeth; manipulating a plurality of segmented tooth components based on the first digital data set so as to generate 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 first arrangement toward a final arrangement; and after generating the plurality of intermediate digital data sets, generating a plurality of shell appliances based on the plurality of intermediate digital data sets, the plurality of shell appliances each having cavities shaped to receive and resiliently reposition teeth along respective movement paths for the teeth between the first arrangement and the final arrangement. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
