1. An intraoral scanning system, the system comprising:
a wand having at least one image sensor and a near-infrared (near-IR) light source; and
one or more processors operably connected to the wand, the one or more processors configured to:
display a three-dimensional (3D) model of a patient's dental arch;
display a viewing window over a portion of the 3D model of the patient's dental arch;
change a relative position between the viewing window and the 3D model of the patient's dental arch based on input from the user;
identify, from a plurality of near-IR images of the patient's dental arch that were taken from different angles and positions relative to the patient's dental arch, an identified near-IR image taken at an angle and position that approximates a relative angle and position between the viewing window and the 3D model of the patient's dental arch; and
display the identified near-IR image taken at the angle and position that approximates the relative angle and position between the viewing window and the 3D model of the patient's dental arch.
