Abstract: Systems and methods for planning a treatment for a patient's teeth are provided. In some embodiments, a method includes receiving an image of a patient's face and determining a plurality of facial lines using the image of the patient's face. The plurality of facial lines can represent a target smile for the patient. The method can further include outputting a visualization including the plurality of facial lines overlaid onto a composite image. The composite image can include the image of the patient's face combined with a digital model of the patient's teeth. The digital model can represent a tooth arrangement of a treatment plan to adjust the patient's teeth from an initial arrangement toward a target tooth arrangement corresponding to the target smile.

Abstract: Systems and methods for treatment planning using patient facial images are provided. In some embodiments, a method includes receiving a 2D image of a patient's face, generating at least one smile line based on the 2D image, receiving a 3D digital representation of the patient's arch, determining a correspondence between the 2D image and the 3D digital representation, generating a 3D projection of the at least one smile line based on the correspondence, and determining a target arrangement for the patient's teeth based on the 3D projection of the at least one smile line.
