8.3

Rework of the grounded/milled restoration

After the grinding/milling process and prior to sintering, the restoration
must be separated using a carbide milling machine (Dentsply Sirona
recommends: HM489FC 023 from Meissinger).

To prevent milling residues from remaining in the fissures, the
restoration can be briefly steamed off or cleaned with water and a soft
toothbrush.

In the case of dry-milled restorations we recommend that these are
freed from dust using a ceramic brush or compressed air.

Make sure you do not inhale abrasive dusts. Use a vacuum system and
wear a mask.

Block remains and the block holder do not need to be disposed of
separately. They can be disposed of as normal household waste. This
also applies to trepanated restorations.

8.4

Drying before sintering

No drying is required for dry-milled restorations (with no water cooling).

The CEREC software makes a drying program available for the CEREC
SpeedFire furnace for drying restorations.

NOTICE

Prior to sintering in the inFire HTC or inFire HTC speed, restorations
processed with water cooling (wet milling/wet grinding) must be dried
for 10 minutes at 150°C (302°F) in the drying cabinet. Residual
moisture in the material can cause the restorations to burst.

NOTICE

In the case of high humidity

In an environment with a high level of humidity, the restorations can
absorb moisture after drying. For this reason, sintering must take
place within a maximum of one hour after drying.
