Abstract: Methods and media for analyzing a patient's dental arches in order to generate a treatment plan for the dentition when the patient is missing one or more teeth. The methods and media can include indentifying one or more missing teeth, and estimating one or more dimensions of the one or more missing teeth.

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: Method, systems, and devices including: accessing a 3D model including a virtual representation of a patient's dentition at a treatment stage of an orthodontic treatment plan; obtaining an image of the patient's face and at least a portion of the patient's dentition; projecting the obtained image into a 3D space to create a projection of the patient's face and the at least the portion of the patient's dentition; generating a modified image of the patient representing the patient in the treatment stage of the orthodontic treatment plan, where the modified image is formed by combining the patient's dentition of the accessed 3D model with the patient's face of the projection; and sending instructions to display the modified image of the patient on an output device.

Abstract: Methods and systems for generating composite images of a patient and models of the patient's dentition are provided. In some embodiments, a method includes generating a plurality of 3D models, each comprising a virtual representation of the patient's dentition at different treatment stages of a treatment plan and obtaining an image of the patient's face and dentition. The method can include projecting the obtained image into a 3D space to create a projected 3D model of the patient's face and dentition. The method can also include generating a plurality of modified images, each representing the patient in a treatment stage of the treatment plan and formed by combining the patient's dentition of one of the 3D models with the patient's face of the projected 3D model. A modified image corresponding to a selected treatment stage and a corresponding 3D model can be provided for display.
