1. A method for reducing metal artifacts in a volume radiographic image of a region which includes at least a part of a dental arch and surrounding tissue, the method comprising the steps of:
acquiring an intraoral optical image of the region;
acquiring an X-ray cone beam scan of the region;
registering the intraoral optical image with a reconstructed volume of the X-ray cone beam scan;
identifying the location of metal in the reconstructed volume using the registered optical intraoral image; and
using the identified location of metal in the reconstructed volume to reduce metal artifacts in a subsequent reconstructed volume of the cone beam scan.
