1. A method for scanning obstructed intraoral structures of a patient, the method comprising:

  • providing a hand-held intraoral scanner, wherein the hand-held intraoral scanner is configured to focus light onto an intraoral structure;

    scanning, using the hand-held intraoral scanner, the intraoral structure of the patient to generate first 3D data of a surface of the intraoral structure of the patient;

    generating a 3D virtual model of the intraoral structure of the patient based on the first 3D data;

    determining a missing portion of the 3D virtual model that are missing a portion of the intraoral structure of the patient;

    generating second 3D data representing the intraoral structure of the missing portion of the 3D virtual model;

    combining the second 3D data with the 3D virtual model such that the 3D virtual model includes a representation of the intraoral structure in place of the missing portion.
