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: Dental hygiene and periodontal hand instrumentation requires alignment of the cutting surface of the instrument at a specific angle and adaptation to the tooth surface. A dental hygiene and periodontal hand instrumentation tutor provides an objective, consistent and accurate way to measure and display the actual angulation and adaptation angles of a periodontal hand instrument and assess instrument use continuously. The method includes detecting the position, orientation, motion path, pressure, angulation angle, adaptation angle, and centerline angle of a periodontal hand instrument and comparing them to ideal positions, orientations, and motion paths; and provides various forms of user feedback.

Abstract: An interproximal reduction (IPR) kit and method for using the same. The patient takes their own dental impression and submits it to a dental service provider for a treatment plan. A set of aligners based on the treatment plan are then delivered to the patient as part of a kit. The kit also includes a set of written instructions and/or a treatment diagram and a plurality of strips used to reduce the widths of specific spots of the patient's teeth according to the treatment plan. The patient follows the reapproximation instructions or is instructed to go to a website for supervision for the performance of the reapproximation process. After sufficient instruction, the patient applies the plurality of strips to the correct spots between their teeth. Once reapproximation is complete, the patient is ready to begin wearing the aligners as dictated by the treatment plan.

Abstract: A dental instrument configured to measure a degree of tapering of a side wall of a tooth is described. The dental instrument may include a handle and a taper measuring component coupled to a distal end of the handle. The taper measuring component includes a first, second, and third elongated member. A bottom surface may be formed at a coupling point of the second and third elongated member, where the second elongated member is configured to be substantially vertical when the bottom surface is placed adjacent to a tooth, and the third elongated member projecting radially from the second elongated member at a predefined angle. The third elongated member is shaped and positioned to rest substantially flush along the at least one side wall of the tooth when a degree of tapering of the tooth is substantially similar to the angle, and may include a measuring component.
