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 reference object 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 reference object to the intraoral image and/or the virtual 3D model based on the one or more known properties of the reference object. 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: Embodiments relate to techniques for real-time and post-scan visualization of intraoral scan data, which may include 3D images, 3D scans, 3D surfaces and/or 3D models. In one embodiment, an intraoral scanning system comprises a plurality of image sensors to periodically generate a set of intraoral two-dimensional (2D) images, wherein for each set of intraoral 2D images each image sensor of the plurality of image sensors is to generate an intraoral 2D image, and wherein relative positions and orientations of the plurality of image sensors are known. The intraoral scanning system further comprises a computing device, wherein the computing device is to perform the following for each set of intraoral 2D images: generate a combined intraoral image based on merging the set of intraoral 2D images together during scanning; and output the combined intraoral image to a display.

Abstract: In a method of generating a virtual 3D model of a dental site, scan data comprising an intraoral image is received during an intraoral scan of a dental site. A representation of a foreign object is identified in the intraoral image based on a color analysis of the scan data. The intraoral image is modified by removing the representation of the foreign object from the intraoral image. Additional scan data comprising a plurality of additional intraoral images of the dental site is received during the intraoral scan. A 3D surface of the dental site is then generated using the modified intraoral image and the plurality of additional intraoral images.

Abstract: A scanning system comprises an intraoral scanner to capture scan data of a dental site and a computing device to generate a 3D rendering of the dental site. The scanner comprises one or more input devices configured to provide manual interaction with the computing device, where: a first activation of the input device(s) causes the scanning system to enter the scan mode, wherein the 3D rendering has a first visualization during the scan mode; and a second activation of the input device(s) causes the scanning system to enter an overlay mode, wherein the 3D rendering has a second visualization during the overlay mode, wherein the computing device is to present a menu comprising menu options on the display while the scanning system is in the overlay mode, and wherein the scanner is usable to select among the presented menu options.

Abstract: A system for intraoral scanning comprises a scanner to generate image data of a dental site and a computing device. The computing device receives the image data of the dental site, the image data comprising a representation of the dental site and a representation of a reference object at the dental site. The computing device selects library data for the reference object from library data for a plurality of reference objects in a library. The computing device aligns the library data for the reference object with the image data.

Abstract: Improved dental models for use in dental procedures are provided. In one aspect, a unitary dental model of an intraoral cavity of a patient having a dental implant comprises a physical surface representative of gingival tissue of the patient. The model can comprise a channel shaped and oriented to receive an abutment corresponding to a physical abutment to be connected to the dental implant, in which the channel extends to an opening in the physical surface. The channel can comprise a first portion shaped to receive and constrain a corresponding structure of the abutment to a position and orientation and a second portion shaped to receive a fastener to couple the abutment to the unitary dental model. In many embodiments, the first portion comprises a shoulder shaped to receive the corresponding structure of the abutment in order to position the abutment along the channel.

Abstract: In embodiments, a processing device generates a three-dimensional model of a dental site from scan data, the three-dimensional model comprising a representation of a tooth, wherein a portion of the three-dimensional model comprises an interfering surface that obscures a portion of the tooth. The processing device receives or generates an image of the tooth, wherein the image depicts the interfering surface. The processing device processes the image to generate a modified image, wherein the portion of the tooth that was obscured by the interfering surface in the image is shown in the modified image. The processing device updates the three-dimensional model of the dental site by replacing, using the modified image, the portion of the three-dimensional model that comprises the interfering surface that obscures the portion of the tooth, wherein the portion of the tooth that was obscured in the three-dimensional model is shown in an updated three-dimensional model.
