Abstract: Remote progress tracking of orthodontic treatment may include receiving a 3D digital model of a patient's dentition including the patient's teeth. A 3D digital model of an impression of occlusal surfaces of the patient's teeth may be generated. The teeth of the 3D digital model of the patient's dentition may be registered to the position and orientation of the patient's teeth in the 3D digital model of the impression of the occlusal surfaces of the patient's teeth. An updated 3D digital model of the patient's teeth may be generated based on the registration.

Abstract: An apparatus for determining surface topography of a patient's teeth comprises a probe sized to be at least partially inserted into an intraoral cavity of the patient, a light source to output light; and a light focusing assembly. The light focusing assembly comprises a first lens, a second lens and a focus changing assembly comprising one or more additional lenses that shares an optical axis with the first lens and the second lens and being configured to focus the light to a plurality of external focal planes to illuminate the patient's teeth, wherein the focus changing assembly has a movement gain factor, and wherein as a result of the movement gain factor a change in separation between lenses of the focus changing assembly by a first distance results in a change in a focus setting by a second distance that is 2-10 times greater than the first distance. The apparatus further comprises a detector configured to measure one or more characteristics of incident light returning from the illuminated patient's teeth and a processor coupled to the detector and configured to generate data representative of a topography of the patient's teeth based on the one or more measured characteristics of the incident light returning from the illuminated patient's teeth.

Abstract: A system includes a memory and a processing device operatively coupled to the memory. The processing device receives an image of a smile of an individual comprising initial contours of teeth of the individual, receives or generates image data comprising target contours of the teeth of an individual, and generates a new image based on the received image data and one or more parametric functions associated with tooth color determined from the image of the smile, wherein a shape of the teeth in the new image is based on the received image data and a color of the teeth in the new image is based on applying the one or more parametric functions to at least a portion of the image data.

Abstract: A method for preparing a tooth crown may include generating a 3D model of an external surface of a patient's tooth and generating a 3D model of an external surface of a first crown based on the 3D model of the external surface of the patient's tooth. The method may also include preparing the patient's tooth to receive the first crown while generating the 3D model of the external surface. A 3D model of the prepared tooth my be generated. A 3D model of an internal surface of the first crown may also be generated. The 3D model of the external surface and the 3D model of the internal surface may form a 3D model of the first crown.

Abstract: Systems and methods of simulating dental treatments are disclosed. A method may include capturing a first 2D image of a patient's face, including the patient's teeth, building a parametric 3D model of the patient's teeth and gingiva based on the first 2D image, developing a simulated outcome of a dental treatment of the patient's teeth by rendering the parametric 3D model with the patient's teeth in one or more positions and/or orientations corresponding to the treatment goals of the dental treatment plan, and rendering a second 2D image of the patient's face with gingiva and teeth according to a simulated outcome of the dental treatment plan. As noted herein, the dental treatment plan may include orthodontic and/or restorative elements. The simulated outcome may correspond to estimated outcomes and/or intended outcomes of the dental treatment plan.

Abstract: Calibrating an intraoral scanner includes obtaining reference data of a reference three-dimensional (3D) representation of a calibration object and obtaining, based on the intraoral scanner being used by a user to scan the 3D calibration object, and from one or more device to real-world coordinate transformations of two-dimensional (2D) images of the 3D calibration object, measurement data. Calibrating the intraoral scanner further includes aligning the measurement data to the reference data to obtain alignment data and updating, based on the alignment data, said one or more transformations.
