firing Fusion/Crystallization Firing
The glass-ceramic fusion of the IPS e.max ZirCAD framework and the IPS e.max CAD veneering structure is first conducted
without the application of IPS e.max CAD Crystall./Glaze, Shades or Stains. The characterizations (Shades, Stains) and the
Glaze are applied to the tooth-coloured restoration and fired in a separate Characterization/Glaze firing.
Please observe the following procedure for the Fusion/Crystallization firing:
– Keep the joined and cleaned restoration away from liquids and do not steam.
– Only the IPS e.max CAD Crystallization Tray and the corresponding IPS e.max CAD Crystallization Pins must be used for
the Fusion/Crystallization 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.
– A maximum of 6 units (e.g. 6 single crowns or two 3-unit bridges) may be placed on the IPS e.max CAD Crystallization
Tray.
– Carry out the Fusion/Crystallization firing with the indicated parameters (p. 37). Observe the furnace type!
– At the beginning of the firing procedure, open the furnace and wait for the acoustic signal. Subsequently, place the
firing tray with the objects in the centre of the firing table and start the program.
– 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).
– Allow the restoration to cool to room temperature in a place protected from draft.
– Do not touch the hot restoration with metal tongs.
Note on the Fusion/Crystallization firing
A special firing program with pre-drying function has been developed for the Fusion/Crystallization firing in the
IPS e.max CAD-on technique. The firing parameters have been precisely adjusted to the IPS e.max CAD Crystall./
Connect fusion glass-ceramic. This ensures optimum firing results.
The following ceramic furnaces can be used for this firing.
– Programat P300
–> In order to offer all the required program functions the software version V5.1 or higher must be
installed on the ceramic furnace.
– Programat P500, P700 and EP5000
–> The required firing parameters can be entered manually.
Place the restoration on the positioned IPS e.max CAD Crystallization Pins
on the IPS e.max CAD Crystallization Tray.
Apply some IPS Object Fix Putty or Flow material to the cavity of the restoration to place the
restoration on the IPS e.max CAD Crystallization Pins.
