Claim 9:
10. An intraoral scanning system, the system comprising:
a wand having at least one image sensor and a near-infrared (near-IR) light source;
a display output; and
one or more processors operably connected to the wand and the display output, the one or more processors configured to:
display a three-dimensional (3D) model of a patient's dental arch on the display output;
display a viewing window over a portion of the 3D model of the patient's dental arch on the display output;
receive an input from the user changing relative positions of the viewing window and the 3D model of the patient's dental arch;
continuously identify, as the relative positions of the viewing window and the 3D model of the patient's dental arch change, an identified near-IR image derived 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, wherein the identified near-IR image approximates an angle and position that is between the viewing window and the 3D model of the patient's dental arch; and
display the identified near-IR image on the display output.
