Abstract: Systems, methods, devices, and apparatus for positioning a patient's mandible in response to sleep apnea status are provided herein. In one aspect, a system for monitoring and treating sleep apnea in a patient comprises one or more sensors configured to monitor the patient for symptoms associated with sleep apnea; an intraoral appliance worn by the patient, one or more processors, and memory comprising instructions executable by the one or more processors to cause the one or more processors to: receive a set of sensor data from the one or more sensors, detect, using a machine learning algorithm, onset of a sleep apnea event based on the set of sensor data, and transmit a control signal to the intraoral appliance to cause the intraoral appliance to displace a lower jaw of the patient from a first position to a second position in order to treat the sleep apnea event.

Abstract: Methods and apparatuses for generating a model of a subject's teeth. Described herein are intraoral scanning methods and apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth) including both surface features and internal features. These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth. Any of these methods and apparatuses may use minimum scattering coefficients and/or segmentation to form a volumetric model of the teeth.

Abstract: Data from an intraoral scan is received, the data comprising a plurality of intraoral images of a dental site. At least two intraoral images are identified that comprise a representation of at least a portion of a non-rigid object that was affixed to the dental site at a target area. Image registration is performed between the at least two intraoral images using the non-rigid object identified in the at least two intraoral images. A 3D model of the dental site is generated based on the image registration. A representation of the non-rigid object is subtracted from the 3D model based on the known properties of the non-rigid object. A surface of a portion of the dental site is interpolated where the non-rigid object was located based on a) data for other portions of the dental site and b) the surface of the base of the non-rigid object.

Abstract: During an intraoral scan session, a processing device receives a first intraoral image of a dental site and identifies a candidate intraoral area of interest from the first intraoral image. The processing device receives a second intraoral image of the dental site and verifies the first candidate intraoral area of interest as an intraoral area of interest based on comparison of the second intraoral image to the first intraoral image. The processing device then provides an indication of the intraoral area of interest during the intraoral scan session.

Abstract: Processing logic makes a comparison between first image data and second image data of a dental arch and determines a plurality of spatial differences between a first representation of the dental arch in the first image data and a second representation of the dental arch in the second image data. The processing logic determines that a first spatial difference is attributable to scanner inaccuracy and that a second spatial difference is attributable to a clinical change to the dental arch. The processing logic generates a third representation of the dental arch that is a modified version of the second representation, wherein the first spatial difference is removed in the third representation, and wherein the third representation comprises a visual enhancement that accentuates the second spatial difference.

Abstract: A processing device receives image data of an actual condition of a patient's dental arch at an intermediate stage of a multistage orthodontic treatment plan. The processing device compares the image data of the actual condition of the patient's dental arch to a planned condition of the patient's dental arch for the intermediate stage. The processing device identifies one or more clinical signs that the actual condition of the patient's dental arch has a deviation from the planned condition of the patient's dental arch for the intermediate stage of the multi-stage orthodontic treatment plan based on a result of the comparing. The processing device determines one or more probable root causes for the deviation based on the one or more clinical signs. The processing device additionally determines one or more corrective actions for the multi-stage orthodontic treatment plan based on the one or more probable root causes.

Abstract: A system comprises a scanner, an augmented reality (AR) display and a computing device. The scanner generates intraoral images of a dental arch and the AR display generates additional image data representative of a view from a wearer of the AR display. The computing device receives the intraoral images from the intraoral scanner, generates a virtual three-dimensional model of at least a portion of the dental arch from the intraoral images, receives the additional image data from the AR display, determines, from the additional image data, a region of the view that is outside of the dental arch, generates a visual overlay comprising the virtual three-dimensional model, and sends the visual overlay to the AR display. The AR display displays the visual overlay such that the virtual three-dimensional model is shown in the region of the view that is outside of the dental arch.

Abstract: A processing device receives a first virtual 3D model and a second virtual 3D model, each comprising one or more teeth of a patient. The processing device compares the first virtual 3D model to the second virtual 3D model and determines, as a result of the comparing, a difference between the first virtual 3D model and the second virtual 3D model at a dental site comprising a tooth of the one or more teeth. The processing device determines whether the difference comprises a first type of change to the tooth that is indicative of tooth wear or a second type of change to the tooth that is indicative of tooth movement associated with orthodontic treatment. Responsive to determining that the first difference comprises the first type of change to the first tooth, the processing device generates a first indicator of the tooth wear for the tooth.

Abstract: A physical model of at least a portion of a patient's dentition has model dental surfaces corresponding to real dental surfaces of the patient's dentition. The physical model includes one or more targets, each configured for facilitating placement of an orthodontic appliance on the model at a desired location. The targets lack mechanical stops that are outwardly protruding from the original model dental surfaces. Also provided are a method of manufacturing a physical model for use in indirect bonding procedures, a method for indirect bonding for use in an orthodontic procedure, a method for providing an indirect bonding transfer tray for use in an orthodontic procedure, and a system for providing a physical model for use in indirect bonding orthodontic procedures.
