Patent ID: 8417493

Claim:
A scanning placement system comprising: a first plate module including a plurality of alignment spheres, the alignment spheres of the first plate module being configured to fit with a base of a scanning device to couple the first plate module to the base at a known location, the first plate module also being configured to retain a first physical model of a first dentition of a patient and to position the first physical model on the scanning device within a first coordinate system; and a second plate module including a plurality of alignment spheres, the alignment spheres of the second plate module being configured to fit with the base of the scanning device to couple the second plate module to the base at a known location, the second plate module also being configured to retain a second physical model of a second dentition of the patient and to position the second physical model on the scanning device within a second coordinate system, the second plate module also being configured to operably couple to the first plate module on the base of the scanning device to form a combined apparatus within the first coordinate system.
