1. A method for defining a fit between a set of upper and lower teeth in a masticatory system of a patient, comprising:
determining an occlusion from the computer representation of the masticatory system using one or more keys;
digitally modeling the set of teeth in a plurality of different arrangements representing successive repositioning of the patient's teeth from a first arrangement toward a desired arrangement; and
generating a patient removable appliance for each of a plurality of the 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 one arrangement toward a successive arrangement, wherein the plurality of appliances is generated prior to the patient wearing an appliance of the plurality so as to reposition the teeth.
2. The method of claim 1, wherein one of the keys is based on a molar relationship.
22. The method of claim 21, wherein the teeth are free of undesirable rotations.
27. The method of claim 26, wherein the plane ranges between flat and a curve of Spee.
generating an ideal model of the teeth based on the identified features.
36. The method of claim 35, wherein at least one of the feature is identified automatically.
generating a model of the teeth; and
52. The method of claims 51, wherein the model is based on an abstract model of idealized teeth placement.
generating a model of the teeth, the model having a visual appearance; and
57. The method of claims 56, wherein the model is based on an abstract model of idealized teeth placement.
58. A computer-implemented apparatus for defining a fit between a set of upper and lower teeth in a masticatory system of a patient, the apparatus comprising a computer-readable storage medium comprising instructions operable to cause a programmable processor to:
determine an occlusion from the computer representation of the masticatory system using one or more keys;
digitally model the set of teeth in a plurality of different arrangements representing successive repositioning of the patient's teeth from a first arrangement toward a desired arrangement; and
generate a patient removable appliance for each of a 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 one arrangement to a successive arrangement, wherein the plurality of appliances is generated prior to the patient wearing an appliance of the plurality so as to reposition the teeth.
59. The apparatus of claim 58, wherein one of the keys comprises a molar relationship, a crown angulation, a crown inclination, teeth rotations, teeth contact points, or an occlusal plane.
60. A system for defining a fit between a set of upper and lower teeth in a masticatory system of a patient, comprising:
generate a computer representation of the masticatory system of the patient; and
61. The system of claim 60 wherein one of the keys comprises a molar relationship, a crown angulation, a crown inclination, teeth rotations, teeth contact points, or an occlusal plane.
62. The system of claim 60, wherein the data storage device storing instructions operable to cause the processor to identify an ideal base model for the final position of the teeth.
63. The system of claim 62, wherein the ideal base model includes an arch curve.
64. The system of claim 62, further comprising instructions to place a marker on each tooth.

66. The system of claim 65, further comprising instructions to adjust the position and orientation of the teeth.
67. The system of claim 66, further comprising instructions to set the position and orientation of the teeth so that the arch curve passes though the marker within a predetermined deviation.
68. The system of claim 64, where the instructions allow a user of the system to place the marker.
69. The system of claim 64, where the instructions automatically place the marker.
70. A method for defining a fit between a set of upper and lower teeth in a masticatory system of a patient useful for generating a plurality of patient removable appliances having teeth receiving cavities, the cavities of successive appliances having different geometries shaped to receive and resiliently reposition the teeth from one arrangement to a successive arrangement, the method comprising:
generating a first computer representation of the masticatory system of the patient representing an ideal model of the patient's teeth;
determining an occlusion from the first computer representation of the masticatory system using one or more keys;
generating a second computer representation of the masticatory system of patient, the generating comprising optimizing placement of teeth by selecting occlusion index reducing movements to one or more teeth of the first computer representation; and
generating a plurality of at least three geometrically distinguishable tooth arrangements representing the successive repositioning of the teeth from one arrangement to a successive arrangement,
wherein the plurality of tooth arrangements is generated prior to the patient wearing an appliance of the plurality so as to reposition the teeth.
71. A method as in claim 70, further comprising generating the plurality of patient removable appliances using the plurality of tooth arrangements wherein the appliances when worn successively by the, patient resiliently reposition the teeth from one arrangement toward a successive arrangement.
72. A method as in claim 70, wherein the successive arrangement comprises an arrangement of the patient's teeth defined by the second computer representation.
This application is a continuation of U.S. patent application Ser. No. 10/047,078,filed Jan. 14, 2002, now U.S. Pat. No. 6,685,469 which was a continuation of application Ser. No. 09/313,291, filed May 13, 1999, now U.S. Pat. No. 6,406,292, which was a non-provisional of Application No. 60/110,189, filed Nov. 30, 1998. The full disclosures of the above applications are incorporated herein by reference.
The cusp-groove and the marginal-ridge conditions of the molars, the cuspembrasure relationship of the premolars and canines, and incisor overjet can be observed directly from the buccal perspective. A facial axis of the clinical crown (FACC) measurement is used to permit assessment of the lingual-cusp occlusion of the molars and premolars when these teeth are viewed from their mesiobuccal aspect, as explained below.
