1. An intraoral scanning system comprising:
a hand-held wand having at least one image sensor and one or more light sources, wherein the one or more light sources are configured to emit visible light and a near-infrared (near-IR) light;
a display output;
a user input device; and
one or more processors operably connected to the hand-held wand, the one or more processors configured to:
display a three-dimensional (3D) model of a patient's dental arch on the display output;
display an indicator over a portion of the 3D model of the patient's dental arch on the display output;
change in a relative position between the indicator and the 3D model of the patient's dental arch based on input from the user input device;
identify, from both the 3D model of the patient's dental arch and a plurality of images of the patient's dental arch taken from different angles and positions relative to the patient's dental arch, a two-dimensional (2D) image based on a relative angle and position between the indicator relative to the 3D model of the patient's dental arch; and
display the identified 2D image based on the relative angle and position between the indicator relative to the 3D model of the patient's dental arch.
