Characterization/Glaze firing with IPS e.max Ceram
The following paragraphs will explain the steps of characterizing and glazing with IPS e.max Ceram.
If hybrid abutment crowns are fabricated, the entire outer surface may be
individually characterized with IPS e.max Ceram Shades,
Essences, and Glaze.
If hybrid abutments are fabricated, only the area of
the emergence profile is characterized with IPS e.max Ceram
Shades, Essences and Glaze.
Required materials
– IPS e.max Ceram Essences are intensively shaded stains in powder form.
– IPS e.max Ceram Shades are ready-to-use stains in syringes.
– IPS e.max Ceram Glaze and Stain Liquid (allround, longlife) to mix the
materials in powder form (Essences, Glaze), as well as to thin paste materials
(Shades, Glaze).
IPS e.max CAD Crystall./Shades, Stains, Glaze and IPS e.max Ceram Shades, Essence, Glaze must not be
mixed with each other!
The following steps must be observed:
– Clean the finished ceramic structure with the steam jet to remove any contaminations and grease residue. Any conta-
mination after cleaning must be prevented.
– 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 Liquid allround or longlife to the desired consistency.
– 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 hybrid 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 hybrid abutments are fabricated, only the area of the emergence profile is characterized with IPS e.max Ceram Shades
and Essences.
– Secure the ceramic structure on the firing pin of the honey-comb tray with a little IPS Object Fix Putty or Flow for firing.
Important:
The characterization must neither reach the bonding surface to the Ti base nor the screw channel, as this may
compromise the accuracy of fit. Check the interface before firing and carefully remove any contamination.
On the hybrid abutment, do not apply any materials to the bonding surface to the crown, as this may compromise
the fit of the crown.
Conduct the Characterization/Glaze firing for IPS e.max Ceram on a honey-comb firing
tray using the stipulated firing parameters. Firing parameters see page 64
