Abstract: A system and method for simulating orthodontic treatment using augmented reality. An electronic image of a user's face is received from a digital camera, and a region of interest in the image is identified where the region includes the user's teeth. Virtual orthodontic appliances are placed on the user's teeth in the image, and the user's image with the virtual orthodontic appliances is displayed on an electronic display device. The method occurs in real-time to provide the user with the augmented image simulating treatment when or shortly after the image of the user is received. The system and method can display a 3D representation of the user's face augmented with the virtual appliances. The user's augmented image or 3D representation can also be supplemented for display with an image or model of the user's facial anatomy such as an x-ray or a cone beam computed tomography image.

Abstract: Methods for generating multiple orthodontic treatment options for a digital 3D model of teeth in malocclusion. The method generates a plurality of different orthodontic treatment plans for the teeth and displays in a user interface the digital 3D model of teeth in malocclusion with a visual indication of each of the plurality of different orthodontic treatment plans. The visual indication of the treatment plans can be overlaid on the digital 3D model of teeth in malocclusion and possibly include aligners, brackets, or a combination of aligners and brackets. A doctor, technician, or other user can then select one of the treatment plans for a particular patient.

Abstract: A method for displaying teeth after planned orthodontic treatment in order to show persons how their smiles will look after the treatment. The method includes receiving a digital 3D model of teeth or rendered images of teeth, and an image of a person such as a digital photo. The method uses a generator network to produce a generated image of the person showing teeth of the person, the person's smile, after the planned orthodontic treatment. The method uses a discriminator network processing input images, generated images, and real images to train the generator network through deep learning models to product a photo-realistic image of the person after the planned treatment.

Abstract: An automated method for generating a final setup for orthodontic treatment. The method includes receiving a digital 3D model of teeth in an initial state. The method computes a scoring function based upon metrics related to the initial state to generate a corresponding score, perturbs the state of the teeth through translations and rotations of a tooth or set of teeth to generate a perturbed state of the teeth, and updates the state of the teeth based upon the score and the perturbed state of the teeth to generate one or more final setups representing a final state of the teeth after the orthodontic treatment.

Abstract: Methods for generating intermediate stages for orthodontic aligners using machine learning or deep learning techniques. The method receives a malocclusion of teeth and a planned setup position of the teeth. The malocclusion can be represented by translations and rotations, or by digital 3D models. The method generates intermediate stages for aligners, between the malocclusion and the planned setup position, using one or more deep learning methods. The intermediate stages can be used to generate setups that are output in a format, such as digital 3D models, suitable for use in manufacturing the corresponding aligners.
