Abstract: A system comprises an image capture device, an augmented reality (AR) display to display, and a processing device. The processing deice receives image data of a dental arch from the image capture device and processes the image data using a plurality of detection rules, where each detection rule detects one or more dental conditions. The processing device determines a dental condition for the dental arch based on the processing, determines a position of an area of interest on the dental arch, wherein the area of interest is associated with the dental condition, generates a visual overlay comprising an indication of the dental condition at the position of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.

Abstract: Systems and methods for monitoring a subject's teeth during orthodontic treatment. An input 2D image of the subject's current teeth including a wide angle occlusal view of the subject's upper and/or lower jaw at a current treatment stage can be received. Virtual camera parameters corresponding to the input 2D image can be determined. A rendered 2D image of the subject's teeth can be generated from a 3D model of the subject's upper and/or lower jaw at a planned treatment stage with the virtual camera parameters. Differences between the subject's teeth from the input 2D image and the rendered 2D image using tooth centers can be determined. An indicator indicating the differences can be output.

Abstract: Orthodontic systems for monitoring treatment. The systems can include at least one orthodontic appliance that includes one or more sensors. A processor in communication with the sensor(s) is configured to receive sensor data from the sensor(s), where the sensor data corresponds to a force acting on one or more teeth. The processor is further configured to predict tooth movement based on the sensor data. The predicted tooth movement is determined by predicting how much teeth will move based on a direction and a magnitude of the force. The processor is further configured to compare the predicted tooth movement to an expected tooth movement, where the expected tooth movement is based on a treatment stage of a treatment plan. The processor is further configured to modify the treatment plan if the predicted tooth movement does not match the expected tooth movement based on the treatment stage of the treatment plan.

Abstract: Orthodontic appliances are provided. In some embodiments, an orthodontic appliance includes a polymeric shell having a plurality of teeth-receiving cavities. The polymeric shell can include a discontinuity that is configured to deform when the orthodontic appliance is worn on a patient's teeth. The orthodontic appliance can also include an elastic member having a first portion directly coupled to a first location on the polymeric shell, and a second portion directly coupled to a second location on the polymeric shell. When the orthodontic appliance is worn on the patient's teeth, the elastic member can be configured to cause an interaction with the deformed discontinuity, the interaction eliciting a movement of one or more of the patient's teeth to change a size of an interproximal space between the patient's teeth.

Abstract: A system for intraoral scanning comprises a scanner to generate image data of a dental site and a computing device. The computing device receives the image data of the dental site, the image data comprising a representation of the dental site and a representation of a reference object at the dental site. The computing device selects library data for the reference object from library data for a plurality of reference objects in a library. The computing device aligns the library data for the reference object with the image data.

Abstract: Systems and methods are provided for preparation of orthodontics and prosthodontics. A method may include scanning a patient's teeth to form first 3D data of the patient's teeth including a removable element that obscures part of the dental surfaces of the patient's teeth and non-obscured tooth surfaces, removing the removable element form the patient's teeth so that the removable element no longer obscures the part of the dental surfaces of the patient's teeth, and scanning the previously obscured part of the dental surfaces of the patent's teeth and the non-obscured tooth surfaces.

Abstract: The present disclosure provides method, systems, and devices for expanding arch of teeth. A device for expanding an arch of teeth of a patient can include a removable shell formed of a first material having a number of cavities formed therein. The number of cavities are shaped to receive teeth of a patient. A device for expanding an arch of teeth of a patient can include an arch element extending from the removable shell in a lingual direction and across an arch width of the removable shell. The arch element can be formed of the first material and a second material that is a different material than the first material, can be designed to expand an arch of the teeth of the patient, and can have a width specific to a stage of a treatment plan.

Abstract: Systems, methods, and devices for producing appliances for expansion of the arch of a patient are provided. An arch expanding appliance comprises a force generating portion to apply an arch expansion force and a retention portion to hold the force generating portion on the teeth. The retention portion comprises a flexible portion and a stiff portion. The force generating portion applies a force to move teeth associated with the flexible portion, while the stiff portion resists movement of its associated teeth. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.
