Contouring
Weigh the abutment with the fired IPS e.max Ceram ZirLiner
and record the weight. The weight is used to determine the
wax weight after contouring.
Contour the restoration in accordance with the desired processing technique (staining, cut-back or layering technique).
Please observe the following basic guidelines:
– Isolate the plaster dies with a commercial plaster-wax separator.
– Use only organic waxes for contouring, since they fire without leaving residue.
– Secure the abutment on the model in the correct position and attach the margins with wax.
– Seal the screw cavity with a placeholder (e.g. plastic tube). Isolate the placeholder before contouring.
– Exact contouring for the restoration
– For fully anatomical restorations, the possible occlusal relief must be taken into consideration as early as during the wax-
up, since the application of the Stains and Glaze results in slight increase in vertical dimensions.
Observe the following minimum and maximum layer thicknesses during contouring for pressing over the Straumann
Anatomic IPS e.max Abutment with IPS e.max ZirPress.
– In order to ensure the desired tooth shade as well as complete pressing, a minimum thickness of 0.7 mm must be
observed.
– The maximum thickness of 2.0 mm must not be exceeded.
