1. A computer-implemented method for use in developing a course of treatment for an orthodontic patient, the method comprising:

  • scanning a patient'"'"'s teeth or a physical model thereof to obtain data;

    receiving in a computer the data obtained by the scanning;

    obtaining in the computer a digital model of a patient'"'"'s dentition, including a dental model representing the patient'"'"'s teeth at a set of initial positions and a gingival model representing gum tissue surrounding the teeth; and

    deriving in the computer from the digital model data representing an expected deformation of the gum tissue as the teeth would move from the initial positions to another set of positions.
