1. A method of creating a treatment plan to align a patient's teeth using a plurality of removable aligners to be worn in sequential stages, the method comprising:
receiving, in a processor, a digital model of the patient's teeth;
accessing, by the processor, a set of treatment preferences, a comprehensive final position of the patient's teeth, and a set of treatment details;
selecting a plurality of numerically expressed treatment targets from a memory accessible to the processor, based on the set of treatment details, the set of treatment preferences and the comprehensive final position of the patient's teeth;
combining the plurality of numerically expressed treatment targets to form a single numerical function;
selecting a plurality of numeric limits on the single numerical function based on the set of treatment preferences;
minimizing the single numerical function subject to the plurality of numeric limits to get a solution vector including all stages forming the treatment plan;
mapping the solution vector to the treatment plan, wherein the treatment plan includes a final tooth position that is different from the comprehensive final position of the patient's teeth; and
generating one or more aligners based on the treatment plan.
