Ivoclar Vivadent IPS e.max CAD Chairside v.1 - Handbuch (Seite 103)

51
The following notes should be observed for the crystallization of IPS e.max CAD:
– Carry out the crystallization in a Programat CS or another Ivoclar Vivadent ceramic furnace using the indicated
parameters.
– If you would like to use other, untested ceramic furnaces, please consult Ivoclar Vivadent about their compatibility with
IPS e.max CAD.
– Basically, the following applies:
Ceramic furnaces without
– function for controlled (long-term) cooling
– vacuum function
cannot be used.
– Before the first crystallization and every six months after that, the ceramic furnace must be calibrated.
– Depending on the mode of operation, more frequent calibration should be required. Follow the instructions for the
manufacturer.
The following aspects should be observed for conducting the crystallization:
– Use only IPS Object Fix Putty or Flow as an auxiliary firing paste.
– IPS e.max CAD restorations must not be directly placed on the IPS e.max CAD Crystallization Tray and Pins, e.g. without
auxiliary firing paste, for crystallization.
– Use only the IPS e.max CAD Crystallization Tray and the corresponding IPS e.max Crystallization Pins, since they store the
heat necessary for slow and above all tension-free cooling of the glass-ceramic.
– Always conduct the crystallization under vacuum.
– Always allow the restoration to cool to room temperature after crystallization before further processing.
– Remove IPS e.max CAD objects 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.
– Do not blast or quench the objects.

Please note:
– If glaze paste is used, Speed Crystallization/Glaze Spray must not be used.
– Both Speed Crystallization and Crystallization/Glaze are not suitable for the crystallization of IPS e.max CAD MO.
