Please observe the following procedure for the Characterization/Glaze firing:
– Extrude the ready-to-use IPS e.max CAD Crystall./Glaze Paste from the syringe and mix.
– 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.
– Apply IPS e.max CAD Crystall./Glaze Paste evenly on the areas to be glazed using a small brush. Avoid to apply too thick
a glaze layer. Avoid "pooling", especially on the occlusal surface of the hybrid abutment crown.
– Too thin a glaze layer may lead to an unsatisfactory gloss.
– Apply characterizations with IPS e.max CAD Crystall./Shades and/or IPS e.max CAD Crystall./Stains. For that purpose,
extrude the Shades and Stains from the syringe and mix. If necessary, slightly thin them 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. 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 CAD
Crystall./Shades Incisal may be used. The cusps and fissures can be individualized using Stains.
After glazing and staining, the Characterization/Glaze firing (Corrective firing) is conducted in a compatible ceramic furnace
(e.g. Programat
® CS or Programat P500). When placing the objects into the furnace and setting the firing parameters,
observe the following points:
– Place the restoration in the centre of the IPS e.max CAD Crystallization Tray.
– A maximum of 6 units can be positioned on the firing tray for the firing with IPS e.max CAD Crystall./Glaze Paste.
Important:
– The glazing material 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 might
compromise the fit of the crown.
Important
– Conduct the Corrective firing on the IPS e.max CAD Crystallization Tray using the stipulated firing
parameters.
