Abstract
Example dental scanning methods for analyzing jaws of a patient involve taking multiple scans of the jaws, and/or models thereof, and then shifting the image of one scan to match that of another. In some examples, fiducial markers are attached to the patient's jaws beforehand to accurately identify and track the relative position of the jaws. The methods provide a way for creating a precise image of an upper jaw and a lower jaw in their proper bite registration, even though the resulting image may show an insufficient number of teeth to readily do so. The final, properly shifted image serves as a virtual 3D jaw model that can be manipulated and analyzed to aid in various orthodontic and other dental treatments.
