Ivoclar Vivadent IPS e.max ZirPress - Manual (Page 20)

3. Contouring for the layering technique
Contouring of the “dentin core” and/or ceramic shoulder depends on the available space.
The following points have to be observed:
– Precisely attach the restoration margins and/or shoulder with wax.
– In bridges, contour the basal surface of the bridge pontic.
– Contour the dentin core.
– Observe a wax thickness of at least 0.7 mm to avoid incomplete press results.
Sintered IPS e.max ZirCAD framework onto which IPS e.max Ceram ZirLiner has been fired on the model.
Precisely attach the restoration margins and contour the “dentin area”. In bridges, contour the basal surface of the bridge pontic. Observe the minimum layer thickness of 0.7 mm.
