CAD/CAM Wax Discs

About wax discs

A wax disc is milled into a wax pattern, the positive likeness of the object to be made. The pattern is then cast in metal by the lost-wax technique, the traditional way of making a metal substructure. The FDA lists wax for constructing patterns from which metal crowns and bridges are cast as a Class I device (21 CFR 872.6890).

Not a final material: the milled wax is a pattern that is removed from the mould, usually by heat.
