Abstract: Apparatuses, including sleeves, intraoral scanning systems to use these sleeves, and methods of using the sleeve, that authenticate the sleeve for use with an intraoral scanning system. Authentication may include verifying that the sleeve is new (unused) and/or verifying that the sleeve is appropriate and/or intended for use with the intraoral scanning system. Once authenticated, operation parameters of the intraoral scanning system can be automatically set based on information from a scanned identifier on the sleeve.

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: The present disclosure provides computing device implemented methods, computing device readable media, and systems for motion compensation in a three dimensional scan. Motion compensation can include receiving three-dimensional (3D) scans of a dentition, estimating a motion trajectory from one scan to another, and calculating a corrected scan by compensating for the motion tfajectory. Estimating the motion trajectory can include one or more of: registering a scan to another scan and determining whether an amount of movement between the scans is within a registration threshold; determining an optical flow based on local motion between consecutive two-dimensional (2D) images taken during the scan, estimating and improving a motion trajectory of a point in the scan using the optical flow; and estimating an amount of motion of a 3D scanner during the scan as a rigid body transformation based on input from a position tracking device.

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: Un sistema, que comprende: un módulo de análisis que incluye un escáner intraoral en tres dimensiones (3D); y un módulo de procesamiento acoplado al módulo de análisis para: recibir una pluralidad de exploraciones en tres dimensiones (3D) de una dentición; registrar una exploración distorsionada a una exploración previa y la exploración posterior, determinar si una cantidad de movimiento entre la exploración previa, la exploración distorsionada, y la exploración posterior está dentro de un umbral de registro, estimar una primera trayectoria de movimiento de la exploración previa a la exploración posterior basada en el registro; estimar una segunda trayectoria de movimiento durante un tiempo de exploración de la exploración distorsionada; calcular una exploración corregido para la exploración distorsionado mediante la compensación de la trayectoria de movimiento durante el tiempo de escaneado de la exploración distorsionada, y rechazar una exploración distorsionada en respuesta a la cantidad de movimiento que está fuera del umbral de registro.
