Abstract: In a method of generating a virtual 3D model of a dental site, scan data comprising a plurality of images of a dental site is received during an intraoral scan. An analysis of an image is performed. A representation of a foreign object possibly with known properties is identified in the image based on the analysis. A virtual 3D model of the dental site is generated based on the plurality of images. The image and/or the virtual 3D model of the dental site is modified by adding additional data about the foreign object to or removing data for the foreign object from the intraoral image and/or the virtual 3D model. If the image is modified, it may be modified prior to generation of the virtual 3D model, and the virtual 3D model may be generated using the modified image.

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 an intraoral image of a first intraoral site and determines an identity of the first intraoral site. The processing device then locks the intraoral image and selects a portion of the intraoral image depicting a portion of the first intraoral site based at least in part on the identity of the first intraoral site. The processing device may then generate a model comprising the first intraoral site based at least in part on the locked intraoral image, wherein the portion of the locked intraoral image is used for a first region of the model, and wherein data from one or more additional intraoral images that also depict the portion of the first intraoral site is not used for the first region of the model.

Abstract: Un procedimiento que comprende: mostrar un modelo (617) tridimensional (3D) de la arcada dental de un paciente; mostrar una ventana (1003, 1005) de visualización sobre al menos una porción del modelo 3D de la arcada dental del paciente, donde la visualización de la ventana (1003, 1005) de visualización sobre una porción del modelo 3D de la arcada dental del paciente comprende la visualización de un bucle (1401) a través del cual se puede ver la porción del modelo 3D de la arcada dental del paciente; recibir, de un usuario, un cambio en una posición relativa entre la ventana (1003, 1005) de visualización y el modelo (617) 3D del arco dental del paciente; identificar, a partir del modelo (617) 3D de la arcada dental del paciente y de una pluralidad de imágenes de la arcada dental del paciente tomadas desde diferentes ángulos y posiciones relativas a la arcada dental del paciente, una imagen del IR cercano (1005) tomada en un ángulo y posición que se aproxima a un ángulo y posición relativos entre la ventana (1003, 1005) de visualización relativa y el modelo 3D de la arcada dental del paciente; y mostrar la imagen (1005) identificada del IR cercano tomada en el ángulo y la posición que se aproxima al ángulo y la posición entre la ventana (1003) de visualización en relación con el modelo (617) 3D de la arcada dental del paciente.

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.
