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 processing device receives a plurality of intraoral scans of a dental arch. The processing device determines, from the plurality of intraoral scans, a first set of intraoral scans that depict a restorative object and a second set of intraoral scans that fail to depict any restorative object. The processing device generates a multi-resolution three-dimensional model of the dental arch, wherein a first portion of the multi-resolution three-dimensional model is generated from the first set of intraoral scans, has a first resolution and represents the restorative object, and wherein a second portion of the multi-resolution three-dimensional model is generated from the second set of intraoral scans, has a second resolution and represents a remainder of the dental arch, wherein the first resolution is greater than the second resolution.

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.

Abstract: In embodiments, a processing device detects a margin line in a model of a preparation from one or more images. The processing device determines, for each segment of a plurality of segments of the margin line, a quality score for the segment. The processing device determines that a segment of the margin line has a quality score that is below a quality threshold, wherein the segment of the margin line was generated based on a first set of images. Responsive to determining that the segment of the margin line has the quality score that is below the quality threshold, the processing devices updates the three-dimensional model of the preparation by replacing a portion of the three-dimensional model associated with the segment of the margin line with image data from at least one of a new image or a second set of images.
