Abstract
A target positioning tool for use during the scanning of a dental preparation enables an operator to ensure that the preparation is always properly positioned. In one embodiment, the tool comprises an outer circle and a pair of arcs that are positioned back-to-back. The arcs enable the operator to correctly align the scan to the preparation or with a preparation margin. Preferably, the size of the circle is constant and remains so as the view moves in and out on the display screen.
