Die stone type IV
Fabricating the model
Fabricate a type IV die stone model with detachable
segments according to the impression.
Applying the spacer
It is advisable to apply a sealer to harden the surface and to
protect the die.
The application of a sealer must not cause any changes in
the dimensions of the die.
a) For single crowns, apply two layer of spacer up to
maximum 1 mm from the preparation margin (layer
thickness of spacer: 9–11 µm).
b)Bridge restorations also require two layers of spacer. Apply
an additional layer of spacer to the intercoronal surfaces of
the abutments (the area facing the pontic). This measure
helps prevent undesired friction.
The spacer is applied to maximum 1 mm from the preparation margin.
