1. 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.

Abstract
A system for generating an electronic model having a common coordinate system includes a scanning device; a first plate module; and a second plate module. Each of the plate modules is configured to separately couple to the scanning device. The plate modules also can be moveably coupled together using an articulation device. Each of the plate modules includes alignment structures (e.g., spheres) to facilitate determining a position and orientation of the plate modules within a coordinate system of the scanning device.

15. A method comprising:
-
arranging a first physical model on a scanning device, the first physical model associated with a first alignment sphere, a second alignment sphere, and a third alignment sphere; scanning a surface of the first physical model along a first scan line to find an edge of the first physical model at a first edge point; scanning the surface of the first physical model along a second scan line to find the edge of the first physical model at a second edge point, the second scan line being spaced a distance from the first scan line; determining a first vector crossing the first edge point and the second edge point, the first vector having a first direction; locating the first alignment sphere at a first location, the first location being located along the first vector; and scanning the first alignment sphere to obtain positional data. - View Dependent Claims (16, 17)
