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: A fit detection system for a respiratory protection device is presented that includes an infrared camera that captures an image sequence of a user wearing the respiratory protection device. The system also includes a temperature change detector that analyzes images in the image sequence and detects a temperature change profile of the respiratory protection device. The system also includes a communication component that communicates a fit indication based on the detected temperature change profile.

Abstract: Machine learning, or geometric deep learning, applied to various dental processes and 5 solutions. In particular, generative adversarial networks apply machine learning to smile design—finished smile, appliance rendering, scan cleanup, restoration appliance design, crown and bridges design, and virtual debonding. Vertex and edge classification apply machine learning to gum versus teeth detection, teeth type segmentation, and brackets and other orthodontic hardware. Regression applies machine learning to coordinate systems, diagnostics, case complexity, and 0 prediction of treatment duration. Automatic encoders and clustering apply machine learning to grouping of doctors, or technicians, and preferences.
