IPS
Characterization/Glaze firing
After the Fusion/Crystallization firing, the Characterization/Glaze firing is carried out as a second step. The characterizations
are applied to the tooth-coloured restoration with IPS e.max CAD Crystall./Shades and Stains. This enables a very
precise shade reproduction.
IPS e.max CAD Crystall./Shades are ready-to-use "Dentin" and "Enamel" stains in syringes.
IPS e.max CAD Crystall./Stains are ready-to-use intensive stains in syringes.
IPS e.max CAD Crystall./Glaze Paste is a ready-to-use glazing paste in syringes.
Glaze,
Characterization
For the application of the glaze and characterizations, observe the following procedure:
– Before starting the characterization and glazing procedure, make sure that the outside of the restoration is free from
contamination.
– Hold the restoration in place with diamond-coated tweezers.
– Extrude the glaze material from the syringe and mix thoroughly.
– If a slight thinning is desired, the ready-to-use glaze may be mixed with a small amount of IPS e.max CAD Crystall./Glaze
Liquid. However, the consistency should still remain pasty.
– Apply the glazing material on the entire outer aspect of the restoration. Avoid to apply too thick a glaze layer. Avoid
"pooling", especially on the occlusal surface.
– Too thin a glaze layer may lead to an unsatisfactory gloss.
– In the case of bridges, apply the glaze also to the IPS e.max ZirCAD framework at the basal side of the bridge pontic.
– If characterizations are desired, they can be applied with IPS e.max CAD Crystall./Shades and/or IPS e.max CAD Crystall./
Stains.
– Extrude Shades and Stains from the syringe and mix thoroughly.
– The Shades and Stains may be slightly thinned using IPS e.max CAD Crystall./Glaze Liquid. However, the consistency
should still remain pasty.
– Apply mixed Shades and Stains directly into the unfired glaze layer using a fine brush. The margin of the IPS e.max
ZirCAD framework may also be characterized.
– Only the IPS e.max CAD Crystallization Tray and the corresponding IPS e.max CAD Crystallization Pins must be used for
the Characterization/Glaze firing.
– Place the IPS e.max CAD-on restoration in the centre of the IPS e.max CAD Crystallization Tray.
– For this purpose, place the IPS e.max CAD Crystallization Pins as close as possible to the centre of the IPS e.max CAD
Crystallization Tray.
– The IPS e.max CAD-on restoration may be placed on the IPS e.max CAD Crystallization Pins by means of IPS Object Fix
Putty of Flow material. Apply a small amount of IPS Object Fix Putty or Flow into the cavity of the restoration and place it
on the pins.
– Carry out the Characterization/Glaze firing with the indicated parameters (see p. 41).
– Remove restoration on the IPS e.max CAD Crystallization Tray from the furnace after completion of the firing cycle (wait
for the acoustic signal of the furnace).
– Do not touch the hot restoration with metal tongs.
– Allow the restoration to cool to room temperature in a place protected from draft.
– If required, an additional Characteraization/Glaze firing can be conducted. In total, a maximum of 3 Characterization/
Glaze firings may be conducted.
Note:
Do not use IPS e.max Ceram layering materials
and Shades, Essences or Glaze materials in con-
junction with the IPS e.max CAD-on technique.
