Abstract: Systems and methods for tracking orthodontic treatment using camera images. One or more input two-dimensional (2D) images of a patient's current teeth taken by a camera device can be received.

The rendered 2D image(s) can be based on virtual camera parameters that correspond to the input 2D image(s). One or more rotational differences between the patient's current teeth and the planned treatment stage can be determined by comparing silhouettes of corresponding teeth of the input 2D image(s) to the rendered 2D image(s). A difference indicator indicating the rotational difference(s) can be output.
