Crystallization
The following points should be observed for the crystallization:
– Crystallization should be carried out in an Ivoclar Vivadent ceramic furnace (e.g. Programat
P300, P500 or P700).
– Use only IPS Object Fix Putty or Flow as an auxiliary firing paste to ideally place the restoration
on the firing tray.
– The cavity of the restoration must be entirely filled with IPS Object Putty or Flow and extended so that
there is a reservoir.
– IPS e.max CAD restorations must neither be placed on metal firing pins nor a honey-combed tray for
crystallization.
– Use only the IPS e.max CAD Crystallization Tray, since it stores the heat necessary for slow and above all tension-free
cooling of the restoration.
– Always allow the restoration to cool to room temperature after crystallization before further processing.
Do not place the IPS e.max CAD restoration on metal pins and do not use a honey-combed
firing tray Fill the entire cavity with IPS Object Fix Putty or Flow and extend
Place the restoration supported with IPS Object Fix Putty or Flow on the IPS e.max CAD
Crystallization Tray Place the firing tray in the furnace and start crystallization

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.
