    Abstract: First intraoral images of a first portion of a three-dimensional intraoral object are received. The first intraoral images correspond to an intraoral scan of the three-dimensional intraoral object during a current patient visit. A pre-existing model that corresponds to the three-dimensional intraoral object is identified. The pre-existing model is based on intraoral data of the three-dimensional intraoral object captured during a previous patient visit. A first intraoral image of the first intraoral images is registered to a first portion of the pre-existing model. A second intraoral image of the first intraoral images is registered to a second portion of the pre-existing model.

    Abstract: A system includes an intraoral scanner and a computing device operatively connected to the intraoral scanner. The intraoral scanner generates three-dimensional scan data of a tooth and further performs color measurements of the tooth. The computing device receives the three-dimensional scan data of the tooth during a first mode of operation. The computing device invokes a second mode of operation, and presents, in a graphical user interface (GUI), an image of the tooth. The computing device further presents, in the GUI, data indicating a plurality of color zones of the tooth and further indicating, for at least one color zone of the plurality of color zones, that insufficient color information has been received, wherein each color zone indicates a separate region of the tooth that is expected to have approximately uniform color.

    Abstract: A first multitude of intraoral images of a first portion of a three-dimensional intraoral object are received. A pre-existing model that corresponds to the three-dimensional intraoral object is identified. A first intraoral image of the first multitude of intraoral images is registered to a first portion of the pre-existing model. A second intraoral image of the first multitude of intraoral images is registered to a second portion of the pre-existing model.

    Abstract: Optical scan data including a first set of images representing a first portion of a three-dimensional object is received. A processing device receives ultrasound scan data including a second set of three-dimensional images representing a second portion of the three-dimensional object. The processing device performs image stitching between the second set of three-dimensional images using the optical scan data. The processing device then creates a virtual model of the three-dimensional object based on the stitched second set of three-dimensional images.

    Abstract: An intraoral scanner system includes an intraoral scanner having an imaging device and a sensing face, and a computing device, communicatively coupled to the intraoral scanner. The computing device receives a first intraoral images of a three-dimensional intraoral object of a patient generated by the intraoral scanner corresponding to an intraoral scanning of the three-dimensional intraoral object of the patient. The computing device registers a first intraoral image of the first intraoral images relative to a second intraoral image of the first intraoral images using a model of the three-dimensional intraoral object that existed prior to the intraoral scanning.

    Abstract: The current document is directed to methods and systems that provide semi-automated and automated training to technicians who use oral-cavity-imaging-and-modeling systems to accurately and efficiently generate three-dimensional models of patients' teeth and underlying tissues. The training methods and systems are implemented either as subsystems within oral-cavity-imaging-and-modeling systems or as separate system in electronic communication oral-cavity-imaging-and-modeling systems. The training methods and systems use an already generated, digital, three-dimensional model of a portion of the oral cavity of a particular patient or of a physical model of a portion of an oral cavity to compute a temporal, translational, and rotational trajectory of an oral-cavity-imaging-and-modeling endoscope, or wand, during a training scan. The temporal, translational, and rotational trajectory is used for a variety of different types of instruction and instructional feedback to facilitate training of technicians.
