1. A method of simulating orthodontic treatment, the method comprising:
capturing a first representation, the first representation comprising a depiction of a patient's teeth;
building a parametric model of the patient's teeth based on the first representation, using one or more case-specific parameters for one or more shapes associated with at least one of the patient's teeth;
simulating an outcome of a dental treatment plan for the patient's teeth to produce a simulated outcome of the dental treatment plan; and
modifying the parametric model to provide a modified model representing the simulated outcome of the dental treatment plan.
