If abutments are fabricated, only the area of the emergence profile is characterized
with IPS e.max Ceram Shades and Essences.
If abutment crowns are fabricated, the entire outer surface may be individually
characterized.

The following paragraphs will explain the steps of optional staining and characterizing with IPS e.max Ceram Shades and
Essences. On abutments, only the emergence profile is characterized for the individual patient. This characterization may
also take place at a later stage, i.e. when the crown is characterized.
The Stains and Characterization firing is conducted with IPS e.max Ceram Shades and Essences. For further
information, please refer to the IPS e.max Ceram Instructions for Use.
– IPS e.max Ceram Shades are ready-to-use stains in syringes.
– IPS e.max Ceram Essences are intensively shaded powdered stains, which are mixed with IPS e.max Ceram
Glaze and Stain Liquid.
The following steps must be observed:
– Clean the pressed object with a steam cleaner to remove any contaminations and grease
residue. Any contamination after cleaning must be prevented.
– Tip: For the characterization, place the abutment or the abutment crown on the Ti base using a little IPS e.max Ceram
Glaze and Stain Liquid. This allows you to assess the effect of the Ti base on the shade.
– For better wetting of the stains, a small quantity of IPS e.max Ceram Glaze and Stain Liquid may be slightly rubbed into
the area that needs to be characterized.
– Mix the pastes or powders with the IPS e.max Ceram Glaze and Stain Liquids (allround or longlife) until the desired
consistency is achieved.
– More intensive shades are achieved by several staining procedures and repeated firing, not by applying thicker layers.
– To imitate the incisal area and translucency of the abutment crown in the incisal and occlusal third, IPS e.max Ceram
Shade Incisal may be used.
– The cusps and fissures can be individualized using Essences.
– If abutments are fabricated, only the area of the emergence profile is characterized with IPS e.max Ceram Shades and
Essences. Do not apply materials to the bonding surface to the crown, as this might compromise the fit and the bond.
– Important: Make sure that absolutely no materials are applied to the screw channel and the interface to the Ti base in
order not to compromise the fit and bond.
– Conduct the Stain and Characterization firing on a honey-comb firing tray using the stipulated firing parameters. Please
observe the special firing parameters.
– Remove restoration from the furnace after completion of the firing cycle (wait for the acoustic signal of the furnace).
– Allow the objects to cool to room temperature in a place protected from draft.
– Do not touch the hot objects with metal tongs.
