Model and Tooth Preparation
Fabricate a working model with removable segments as usual. The directions of the manufacturers of the
different CAD/CAM systems regarding the plaster to be used must be observed.
Important for die preparation :
– Check the radius of the incisal/occlusal edge on the prepared die (maxilla and mandible).
– The prepared incisal edge should be at least as thick as the diameter of the bur used in the cavity
during the CAD/CAM process.
– If the incisal edge of the prepared die is thinner than the diameter of the bur, the incisal edge has to
be blocked out accordingly.
– Also observe the information provided by the manufacturer of the CAD/CAM system regarding the die
geometry.
