Abstract: A method includes receiving first intraoral scan data of an intraoral site, the first intraoral scan data having been generated at a first time, receiving second intraoral scan data of the intraoral site, the second intraoral scan data having been generated at a second time that is later than the first time, and analyzing the second intraoral scan data of the intraoral site relative to the first intraoral scan data of the intraoral site. The method further includes identifying an area of interest (AOI) based on the analyzing and removing data for the AOI from at least one of the first intraoral scan data, the second intraoral scan data, or a three-dimensional (3D) model of the intraoral site generated from the first intraoral scan data and the second intraoral scan data.

Abstract: Improved orthodontic appliances, along with related systems and methods, are provided. In one aspect, an appliance includes a shell having a plurality of cavities shaped to receive teeth, a discontinuity formed in the shell, and an elastic member positioned to interact with the discontinuity. In another aspect, an appliance includes a plurality of discrete shell segments joined by an elastic material to form a single appliance shell. In another aspect, an appliance includes a shell having an exterior layer and an interior layer having a stiffness less than a stiffness of the exterior layer, and a discontinuity formed in the exterior layer. In another aspect, an appliance includes a shell comprising an interior surface and an exterior surface, and an elastic coating covering at least a portion of one or more of the interior surface or exterior surface of the shell.

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: 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: A handheld wand comprises a probe at a distal end of the elongate handheld wand. The probe includes a light projector and a light field camera. The light projector includes a light source and a pattern generator configured to generate a light pattern. The light field camera includes a light field camera sensor, the light field camera sensor comprising an image sensor comprising an array of sensor pixels, and an array of micro-lenses disposed in front of the image sensor such that each micro-lens is disposed over a sub-array of the array of sensor pixels.

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: A 3D virtual model of an intra oral cavity in which at least a part of a finish line of a preparation is obscured is manipulated in virtual space by means of a computer or the like to create, recreate or reconstruct finish line data and other geometrical corresponding to the obscured part. Trimmed virtual models, and trimmed physical models, can then be created utilizing data thus created. The virtual models and/or the physical models may be used in the design and manufacture of copings or of prostheses.

Abstract: A dental prosthesis is made by externally machining successive layers of wax, each of which is formed on a previous prosthesis layer and/or on a coping. Each wax layer is used to form a mold in situ over the previous prosthesis layer/coping, and the appropriate prosthesis material is cast or otherwise molded to conform to the wax layer by the mold.
