1. A computer-implemented method for monitoring teeth position during treatment, comprising:
(a) segmenting three-dimensional dental X-ray image data of teeth in a first treatment state to produce segmented X-ray crowns and segmented X-ray roots, each segmented X-ray crown associated with a respective segmented X-ray root;
(b) segmenting optical-scan (OS) image data of the teeth in a second treatment state to produce segmented OS crowns;
(c) comparing, for each tooth, a position and an orientation of each segmented X-ray crown with a position and an orientation of a respective segmented OS crown;
(d) determining, for each tooth, any relative position differences and any relative orientation differences of each segmented X-ray crown relative to the respective segmented OS crown;
(e) for each tooth in which at least one of a relative position difference or a relative orientation difference of a corresponding segmented X-ray crown is determined in step (d), changing at least one of a position or an orientation of the respective segmented X-ray root according to the relative position difference or the relative orientation difference of the corresponding segmented X-ray crown;
(f) for each tooth in which the corresponding segmented X-ray crown has the same relative position and the same relative orientation relative to the respective segmented OS crown, maintaining the position and the orientation of the respective segmented X-ray root.
