– Following the set-up and wax-up procedures, a key is
fabricated using silicone or plaster.
– Remove wax from the model and teeth without
leaving any residue. If a plaster key is used, the model
and the key have to be isolated with Ivoclar Vivadent
Separating Fluid. In addition, the tooth surfaces
requiring adjustments must be roughened.
