A system for repositioning teeth comprises a plurality of individual appliances used with braces. The appliances are configured to be placed successively on the patient's teeth and to incrementally reposition the teeth from an initial tooth arrangement, through a plurality of intermediate tooth arrangements, and to a final tooth arrangement. The appliances may be substituted with braces as appropriate to optimize the treatment of the teeth.

1. A computer-implemented method for repositioning teeth from a first tooth arrangement to a subsequent tooth arrangement, the method comprising: receiving, on a computer, a digital data set comprising a digital model of the patient's teeth in a first arrangement for determining a severity of a malocclusion of a patient;generating, using a computer, based on the determined severity of the patient's malocclusion, a first treatment plan having data comprising a plurality of intermediate digital data sets each corresponding to a different successive tooth arrangement for repositioning the patient's teeth from the first arrangement toward a target arrangement, the treatment plan prescribing a first phase and a second phase in a pre-selected order, the first phase comprising successively placing polymeric shell appliances having tooth receiving cavities having different geometries selected to progressively reposition the teeth, the second phase comprising placing a wire and bracket system to progressively reposition the teeth;receiving, on a computer, evaluation data indicating whether repositioning of the teeth is progressing in a satisfactory fashion after the patient has been administered at least some of the polymeric shell appliances; andgenerating, using a computer, a second treatment plan data in response to the evaluation data, the second treatment plan comprising a prescribed schedule for transitioning between administering to the patient polymeric shell appliances as in the first phase of the first treatment plan and placing a wire and bracket system to progressively reposition the teeth as in the second phase of the first treatment plan. 2. The method of claim 1, further comprising providing a plurality of successively worn polymeric shell repositioning appliances after the placing of a wire and bracket system. 3. The method of claim 1, wherein the evaluating comprises receiving input from a treating professional. 4. A computer-implemented method for formulating a treatment plan for treating a dental malocclusion so as to reposition a patient's teeth toward a desired arrangement, the method comprising: receiving, on a computer, a 3-D digital model of a current arrangement of the patient's teeth;accessing, using a computer, digital data comprising criteria for determining the severity of a patient's malocclusion;generating, using a computer, an identification of a more severe malocclusion of the patient's teeth based on a comparison between the current arrangement digital model and the criteria; andgenerating, using a computer, treatment plan data based on the received digital data and the identification of the more severe malocclusion of the patient's teeth, the treatment plan comprising prescription of a pre-selected order of in seriatim use of both a wire and bracket system and a plurality of successive polymeric shell appliances having tooth receiving cavities, at least two of the appliance having cavities with different geometries selected to progressively reposition teeth toward a desired or prescribed arrangement; wherein the treatment plan data is generated prior to use of the wire and bracket system or plurality of polymeric shell appliances by the patient. 5. The method of claim 4, wherein the criteria indicating a more severe malocclusion comprises: A-P correction of greater than 2 mm;autorotation of the mandible required for vertical/A-P correction;CR-CO discrepancy correction/treatment to other than centric occlusion;correction of moderate to severe rotations of premolars and/or canines that are greater than 20 degrees;severe deep bite opened to ideal or open bite to be closed to ideal;extrusion of teeth greater than 1 mm other than as part of torquing or in conjunction with intruding adjacent teeth;teeth tipped by more than 45 degrees;multiple missing teeth;crowns less than 70% of normal size;posterior open bite; ormovement of entire arch required for A-P correction. 6. The method of claim 4, wherein the treatment plan specifies the use of a wire and bracket system following use of a series of successive shell appliances. 7. The method of claim 4, further comprising: receiving a second indication of the severity of a patient's malocclusion after orthodontic treatment has begun; andgenerating a second treatment plan to use a plurality of successive polymeric shell appliances to resiliently reposition the teeth to a final desired arrangement when the malocclusion is determined from the second indication to be less severe. 8. The method of claim 4, further comprising generating a plurality of digital models representing different arrangements of the patient's teeth progressing from an initial arrangement toward a desired or final arrangement. 9. The method of claim 4, the treatment plan further comprising a prescribed schedule for transitioning between administering to the patient polymeric shell appliances and administering a wire and bracket system. 10. A computer-implemented method for formulating a treatment plan for treating a dental malocclusion so as to reposition a patient's teeth to a final desired arrangement, the method comprising: receiving, on a computer, a digital model of a patient's teeth;generating, using a computer, a determination whether the patient's malocclusion is more severe or less severe, comprising accessing digital data comprising pre-determined criteria indicating severity of a malocclusion and comparing the digital model of the patient's teeth and the criteria; andgenerating and outputting, using a computer, treatment plan data in response to a determination of a more severe malocclusion, the treatment plan comprising prescription of a pre-selected order of in seriatim use of both a wire and bracket system and a plurality of successive polymeric shell appliances having tooth receiving cavities, at least two of the appliance having cavities with different geometries selected to progressively reposition teeth; wherein the combined treatment is selected to reposition the teeth toward a desired or prescribed final arrangement, and wherein the treatment plan is generated prior to the patient being treated with the wire and bracket system and plurality of successive polymeric shell appliances. 11. The method of claim 10, comprising formulating a treatment plan to use a plurality of successive polymeric shell appliances to resiliently reposition the teeth to a final desired arrangement when the malocclusion is determined to be less severe, the appliances having geometries selected to progressively reposition the teeth. 12. The method of claim 10, wherein the determination of severity of the malocclusion comprises input from a treating professional. 13. The method of claim 10, wherein the model is a physical model or digital representation of the teeth.
