E.max, Crystallization parameters, Ip s – Ivoclar Vivadent IPS e.max CAD Labside User Manual
Page 62
The following points should be observed for ceramic furnaces, used for the crystallization of IPS e.max CAD:
– Crystallization should be carried out in an Ivoclar Vivadent ceramic furnace (e.g. Programat P300, P500, or P700).
– 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 to place the restoration directly on the IPS e.max CAD
Crystallization Tray.
– 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 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.
– 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.

Crystallization of IPS e.max CAD MO
Only the program memories 65-69 can be used with the Programat P100.
Please note:
– IPS e.max CAD HT and LT may also be crystallized with this program.
– If only max. two restorations are crystallized at the same time, the closing time S can be reduced to 1:30 min.
