1. A method comprising:
generating, by a processing device, a scan model that is a mathematical model to simulate an imaging process performed by an x-ray imaging device that created a two-dimensional x-ray image of at least one tooth, wherein the scan model uses an initial estimate of one or more parameters of the x-ray imaging device, the one or more parameters comprising a scan angle parameter indicative of a scan angle of the x-ray imaging device;
adjusting a two-dimensional contour of a three-dimensional model to cause a first component of the two-dimensional contour to approximately align with a second component of the two-dimensional x-ray image; and
calibrating the scan model based on data obtained from adjusting the two-dimensional contour.
