Abstract: An apparatus includes a probe sized to be at least partially inserted into an intraoral cavity of a patient and an illumination unit configured to output light. The apparatus includes a light focusing assembly comprising an image space lens, an object space lens and a focus changing assembly between the image space lens and the object space lens and being configured to: overlap a plurality of light beams of the light within the light focusing assembly; and focus the light to a plurality of external focal planes to illuminate the patient's teeth. The apparatus includes a detector 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: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These palatal expanders may be configured to have a variable surface smoothness on one side (e.g., the lingual-facing surface) compared to the opposite side (e.g., the palatal-facing surface). These palatal expanders may be configured to have a varying thickness in the palatal region. These palatal expanders may be adapted for ease in removal by the patient or caregiver (e.g., including a hinged region and/or detachment region, and/or including a thinner buccal side then occlusal side, etc.).

Abstract: The present invention provides methods and systems including orthodontic tooth positioning appliances. An exemplary appliance can include teeth receiving cavities shaped such that, when worn by a patient, repositioning the patient's teeth from a first arrangement toward a subsequent or target arrangement. Appliances can include a cavity having one or more shaped features or protrusions shaped and/or positioned so as to apply a desired force to a patient's tooth received in the cavity and move the tooth along a desired path or direction.

Abstract: A system for generating missing data for 3D models of intraoral structures of a patient. The system may include a hand-held intraoral scanner and a computer having instructions that the system to scan the intraoral structure of a patient to generate first 3D data of the surface of a prepared tooth, generate a 3D virtual model of the prepared tooth based on the first 3D data, determine the 3D virtual model is missing a surface associated with the prepared, generate second 3D data approximating the surface that is determined to be missing from the 3D virtual model intraoral structure that is missing, and combine the second 3D data with the 3D virtual model such that the 3D virtual model includes the approximated surface, wherein the approximated surface approximates the prepared tooth associated with the surface determined to be missing from the 3D virtual model.

Abstract: An intraoral scanner comprises an optical element for transmission of optical signals and a primary housing that houses the optical element, the primary housing comprising a head configured for insertion into a patient oral cavity, the head of the primary housing defining an aperture for transmission of the optical signals, wherein the primary housing comprises a longitudinal axis, and wherein a vector normal to a plane defined by the aperture is at a right angle or an acute angle to the longitudinal axis. The intraoral scanner further comprises a defogging element coupled to the primary housing, the defogging element comprising a transparent substrate aligned with the aperture, at least one side of the transparent substrate facing an external environment, and a transparent conductive layer on a surface of the transparent substrate, wherein responsive to application of electrical power to the transparent conductive layer, the transparent conductive layer generates heat.

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.
