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.

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: Methods and apparatuses for adjusting three-dimensional (3D) dental model data of a patient's dentition to detect and remove one or more attachments on a dental structure (e.g., tooth) of the patient's dentition. These methods and apparatuses may be used for generating treatment plans for treating the patient's teeth, including for more accurately and efficiently aligning the patient's teeth.

Abstract: Methods and apparatuses, including systems, for forming and modifying treatment plans, including modifying treatment plan in real time. In particular are methods and apparatuses for modifying and orthodontic treatment plan in real time that may include the use of an enhanced user interface including a 3D user overlay.

Abstract: Provided herein are methods and apparatuses for analyzing a patient's dental arches in order to generate a treatment plan for the dentition. In particular described herein are methods and apparatuses for analyzing a patient's dental arches when the patient is missing one or more teeth. Methods and apparatuses are provided to properly number the teeth of a patient's arches after a dental scan, including automatically detect missing teeth after a dental scan and estimating the dimensions of the missing teeth. Methods and apparatuses are provided to perform an analysis of the patient's arches that uses the estimated dimensions of the missing teeth. Methods and apparatuses for designing and manufacturing the aligner are also provided.
