SMILE TREATMENT PLANNING SYSTEMS AND METHODS

1 . A method for adjusting an image of a smile, comprising:

receiving a three-dimensional (3D) digital model of a dental arch of a patient;

receiving a digital facial image of the patient which includes an image of one or more teeth of the patient when smiling;

registering the 3D digital model to the one or more teeth of the patient from the digital facial image;

correcting the 3D digital model for scale and distortion to create a corrected 3D digital model;

overlaying the corrected 3D digital model onto the digital facial image;

generating a smile curve or arc which corresponds to a curve or arc of a lower lip of the patient when the lower lip is formed into a smile in the digital facial image; and

adjusting one or more teeth from the corrected 3D digital model according to the smile curve or arc.

2 . The method of claim 1 further comprising overlaying the smile curve or arc in proximity to the one or more teeth on the digital facial image prior to adjusting the one or more teeth from the corrected 3D digital model.

3 . The method of claim 2 further comprising adjusting one or more parameters of the smile curve or arc.

4 . The method of claim 1 further comprising:

estimating a facial anatomy from the digital facial image of the patient;

identifying one or more areas of the facial anatomy affected by a correction treatment of the one or more teeth;

adjusting the one or more areas of the facial anatomy corresponding to the correction treatment.

5 . The method claim 1 further comprising:

identifying one or more parameters relating to smile optimization; and

generating a smile score based on the one or more parameters.

6 . The method of claim 5 further comprising altering one or more parameters to adjust the smile score.

7 . The method of claim 5 wherein the one or more parameters for generating the smile score is selected from the group consisting of smile arc, incisor plane cant, occlusal plane cant, max midline, max transverse display, cuspid inclination, buccal segment inclination, tooth proportionality, flow, gingival display, maxillary central inclination, and COP.

8 . The method of claim 1 further comprising overlaying a plane upon the one or more teeth of the digital facial image to determine a position of one or more brackets upon the one or more teeth.

9 . The method of claim 8 further comprising overlaying images of the one or more brackets upon the one or more teeth on the digital facial image in a corresponding manner.
