Final try-in of the restoration before cementation ... or with steam.
Remove residue with ultrasound in a water bath … Remove the cool restoration from the hardened IPS Object Fix Putty or Flow.
If additional characterizations or adjustments are required after crystallization, a corrective firing using
IPS e.max CAD Crystall./Shades and Stains and Glaze can be conducted. Conduct the corrective firing also on the
IPS e.max CAD Crystallization Tray.
For minor shape adjustments (e.g. proximal or occlusal contact points), IPS e.max CAD Crystall./Add-On is available.
The adjustments may be made with both Crystallization/Glaze and Corrective firing. The detailed procedure is
described on page 36.

Completion of the Restoration
Once the IPS e.max CAD restoration has cooled to room temperature, proceed with the following steps:
– Remove the restoration from the hardened auxiliary firing paste.
– Remove any residue with ultrasound in a water bath and/or with steam.
– Do not blast residues using Al

or glass polishing beads.
– Final try-in of the restoration before cementation.
– If adjustments by grinding are required, make sure that no overheating of the glass-ceramic occurs.
– Use fine-grained diamonds (< 60 µm) for finishing, followed by rubber polishers at low speed and limited pressure. For
the selection of the appropriate grinding tools, refer to the Ivoclar Vivadent Flow Chart “Recommended grinding tools –
chairside”.
– Finally, polish the adjusted areas to a high gloss (e.g. using OptraFine).
– Thoroughly clean the restoration.
