Smile treatment planning systems and methods

A method of adjusting 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;
• generating a smile curve or arc which corresponds to a curve or arc of a lower lip of the patient from the digital facial image;
• overlaying the smile curve or arc in proximity to the one or more teeth on the digital facial image;
• adjusting one or more parameters of the smile curve or arc;
• and
• manipulating one or more teeth from the 3D digital model according to the smile curve or arc.

A method of adjusting a facial image, 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;
• 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.

A method of improving a smile of a patient, 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;
• identifying one or more parameters relating to smile optimization;
• and
• generating a smile score based on the one or more parameters.

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;
• and
• overlaying the corrected 3D digital model onto the digital facial image.
