1. A method of managing delivery of an orthodontic treatment plan, comprising:
- generating a treatment plan for a patient using a computer processor, the plan comprising a plurality of digital models of successive tooth arrangements for moving teeth along a treatment path from an initial arrangement toward a selected final arrangement, the treatment plan further comprising a scheduled treatment-progress tracking event timed to correspond to the patient wearing at least one retention appliance and embodied in a tangible medium;
providing a set of orthodontic shell appliances to the patient, the set of orthodontic shell appliances shaped based on the plurality of digital models of successive tooth arrangements and including the at least one retention appliance, the at least one retention appliance being a duplicate orthodontic shell appliance having the same geometries with respect to tooth receiving cavities as another appliance of the set of orthodontic shell appliances;
tracking progression of the patient'"'"'s teeth along the treatment path after administration of the set of orthodontic shell appliances to the patient, the tracking comprising comparing a digital model of a current arrangement of the patient'"'"'s teeth to a digital model of a planned arrangement of the teeth, wherein the tracking is timed to correspond to the patient wearing the at least one retention appliance according to the treatment plan;
generating a revised treatment plan where it is determined that treatment has progressed substantially off-track.

12. A method of managing orthodontic treatment of a patient, comprising:
-
generating a treatment plan for a patient using a computer processor, the plan comprising a plurality of digital models of successive tooth arrangements for moving teeth along a treatment path from an initial arrangement toward a selected final arrangement, the treatment plan further comprising a scheduled treatment-progress tracking event timed to correspond to the patient wearing at least one retention appliance; providing a set of orthodontic shell appliances to the patient, the set of orthodontic shell appliances shaped based on the plurality of digital models of successive tooth arrangements and including the at least one retention appliance, the at least one retention appliance being a duplicate orthodontic shell appliance having the same geometries with respect to tooth receiving cavities as another appliance of the set of orthodontic shell appliances; tracking progression of the patient'"'"'s teeth along the treatment path after administration of the set of orthodontic shell appliances, the tracking comprising comparing a current arrangement of the patient'"'"'s teeth to a planned arrangement of the teeth; generating a revised treatment plan where it is determined that treatment has progressed substantially off-track, the revised treatment plan comprising one or more digital models of successive tooth arrangements for moving teeth along a second treatment path; and synchronizing at least one aspect of the revised treatment plan so as to integrate revised treatment with an expectation of a treating professional or the patient.

13. A method of providing orthodontic treatment to a patient, comprising:
-
generating an orthodontic treatment plan for a patient using a computer processor, the plan comprising a plurality of digital models of successive tooth arrangements for moving teeth along a treatment path from an initial arrangement toward a selected final arrangement, the treatment plan further comprising a scheduled treatment-progress tracking event timed to correspond to the patient wearing at least one retention appliance; providing a set of shell appliances based on the treatment plan, a first subset of the set of shell appliances shaped such that when successively worn by the patient in a designated sequence progressively move the patient'"'"'s teeth at least partially along the treatment path and a second subset of the set of shell appliances including the at least one retention appliance, the at least one retention appliance being a duplicate appliance having the same geometries with respect to tooth receiving cavities as another appliance of the set of shell appliances; receiving a representation of a current arrangement of the patient'"'"'s teeth following administration of the set of shell appliances and prior to completion of the orthodontic treatment plan; tracking progression of the patient'"'"'s teeth along the treatment path after administration of the set of shell appliances, the tracking comprising comparing a current arrangement of the patient'"'"'s teeth to a planned arrangement of the teeth by matching teeth from a previously segmented digital model to a surface of an unsegmented digital representation of the current arrangement and calculating one or more positional differences between the current and planned arrangements of at least some of the corresponding digital teeth; generating a revised treatment plan where it is determined that treatment has progressed substantially off-track, the revised treatment plan comprising one or more digital models of successive tooth arrangements for moving teeth along a second treatment path; and synchronizing at least one aspect of the revised treatment plan so as to integrate revised treatment with an expectation of a treating professional or the patient.
