1. A computer program for use in a system for defining a fit between a set of upper and lower teeth of a patient and planning orthodontic treatment, the computer program residing on a computer-readable storage medium and comprising instructions operable to cause a programmable processor to: determine an occlusion from a computer model of a set of upper and lower teeth of a patient's teeth;model the set of teeth in a first plurality of different arrangements representing successive repositioning of the patient's teeth from a first arrangement toward a first desired arrangement;output data for visualizing and/or manufacturing a patient-removable appliance for each arrangement of the first plurality of arrangements, the patient-removable appliances having teeth-receiving cavities, the cavities of successive appliances having different geometries shaped to receive and resiliently reposition the teeth from the first arrangement toward a first successive arrangement; andgenerate revised models of the patient's teeth in a second plurality of different arrangements based on mid-treatment dental information, the second plurality representing successive repositioning of the patient's teeth from a second arrangement toward a second desired arrangement. 2. The computer program of claim 1, wherein the occlusion is a functional occlusion. 3. The computer program of claim 1, wherein an arrangement is further based on optimizing placement of teeth by selecting occlusion index reducing movements to one or more teeth. 4. The computer program of claim 3, wherein the occlusion index reducing movements are based on a Peer Assessment Rating index. 5. The computer program of claim 4, wherein occlusion index reducing movements are selected from attempted movements. 6. The computer program of claim 1, wherein determining the occlusion includes using one or more keys based on a molar relationship, a crown angulation, a crown inclination, a tooth rotation, a tooth contact point, or an occlusal plane. 7. A computer program for orthodontic treatment planning, the computer program residing on a computer-readable storage medium and comprising instructions operable to cause a programmable processor to: receive a computer model of a set of upper and lower teeth of a patient's teeth and determine an occlusion;model the set of teeth in a first plurality of different arrangements representing successive repositioning of the patient's teeth from a first arrangement toward a first desired arrangement, wherein positioning of one or more teeth is based partially on teeth features;output data for visualizing and/or manufacturing a patient-removable appliance for each arrangement of the first plurality of arrangements, the patient-removable appliances having teeth-receiving cavities, the cavities of successive appliances having different geometries shaped to receive and resiliently reposition the teeth from the first arrangement toward a first successive arrangement; andgenerate revised models of the patient's teeth in a second plurality of different arrangements based on mid-treatment dental information, the second plurality representing successive repositioning of the patient's teeth from a second arrangement toward a second desired arrangement. 8. The computer program of claim 7, wherein the occlusion is a functional occlusion. 9. The computer program of claim 7, wherein an arrangement is further based on optimizing placement of teeth by selecting occlusion index reducing movements to one or more teeth. 10. The computer program of claim 9, wherein the occlusion index reducing movements are based on a Peer Assessment Rating index. 11. The computer program of claim 10, wherein occlusion index reducing movements are selected from attempted movements. 12. The computer program of claim 7, wherein determining the occlusion includes using one or more keys based on a molar relationship, a crown angulation, a crown inclination, a tooth rotation, a tooth contact point, or an occlusal plane. 13. A method for defining a fit between a set of upper and lower teeth of a patient and planning orthodontic treatment, the method comprising: determining an occlusion from a computer model of a set of upper and lower teeth of a patient's teeth;modeling the set of teeth in a first plurality of different arrangements representing successive repositioning of the patient's teeth from a first arrangement toward a first desired arrangement;outputting data for visualizing and/or manufacturing a patient-removable appliance for each arrangement of the first plurality of arrangements, the patient-removable appliances having teeth-receiving cavities, the cavities of successive appliances having different geometries shaped to receive and resiliently reposition the teeth from the first arrangement toward a first successive arrangement; andgenerating revised models of the patient's teeth in a second plurality of different arrangements based on mid-treatment dental information, the second plurality representing successive repositioning of the patient's teeth from a second arrangement toward a second desired arrangement. 14. The method of claim 13, wherein the occlusion is a functional occlusion. 15. The method of claim 13, wherein an arrangement is further based on optimizing placement of teeth by selecting occlusion index reducing movements to one or more teeth. 16. The method of claim 15, wherein the occlusion index reducing movements are based on a Peer Assessment Rating index. 17. The method of claim 13, wherein determining the occlusion includes using one or more keys based on a molar relationship, a crown angulation, a crown inclination, a tooth rotation, a tooth contact point, or an occlusal plane.
