Abstract: A computer-implemented method for generating a virtual depiction of an orthodontic treatment of a patient is disclosed herein. The computer-implemented method may involve gathering a three-dimensional (3D) model modeling the patient's dentition at a specific treatment stage of an orthodontic treatment plan. An image of the patient's face and dentition may be gathered. A first set of reference points modeled on the 3D model of the patient's dentition and a second set of reference points represented on the dentition of the image of the patient may be received. The image of the patient's dentition may be projected into a 3D space to create a projected 3D model of the image of the patient's dentition. Based on a comparison of the first reference points and projections of the second set of reference points, a plurality of modified images of the patient may be constructed to depict progressive stages of a treatment plan.

Abstract: Orthodontic devices such as aligners, palatal expanders, retainers, and dental implants can be used to adjust the position of teeth and to treat various dental irregularities. To help the clinician or doctor (i.e., orthodontist) design and plan the subject's treatment plan, a 3D digital model of the subject's teeth, dentition, and gingiva can be constructed from a 3D scan of the subject's mouth, teeth, dentition, and gingiva. The 3D model of the subject's teeth and dentition can be displayed graphically to the doctor on a display using a computing system with memory and software.
