Techniques for identifying anatomical dental feature points and related systems and methods

At least one computer readable medium comprising instructions that, when executed by at least one processor, perform a method of determining positions of a plurality of feature points of a patient's tooth based on a statistical tooth model, the method comprising:

• determining values of a plurality of parameters of the statistical tooth model by comparing a three-dimensional (3D) model of a reference tooth, which has a shape parametrized by the plurality of parameters, to a 3D model of a patient's tooth;
• determining positions of a plurality of feature points for the patient's tooth based at least in part on a plurality of feature points associated with the statistical tooth model, and at least in part on the determined values of the plurality of parameters of the statistical tooth model;
• and
• associating the plurality of feature points for the patient's tooth with the 3D model of the patient's tooth according to the determined positions of the plurality of feature points.
