Initial startup

Burning-in sintering aids
Tip: We recommend subjecting all sintering aids (sintering tray, sintering
shuttle) to a gradual burning-in cycle before sintering for the first time. To
do this, load the furnace with the sintering aids and start the "inCoris ZI
classic" program. This also applies to any new sintering aids supplied as
repeat orders.
This procedure extends the service life of the sintering aids.

Sintering zirconium oxide

6.3.2.1

Preparing the sintering tray

NOTICE
Risk of damage to the furnace chamber
If incorrectly positioned, the sintering tray collides with the furnace
chamber insulation.
➢ Ensure that the sintering tray is positioned centrally on the covering,
before closing the furnace or starting the process.
➢ Place the sintering tray on the crucible tray and fill the tray with
sintering pearls as required. Only use original Sirona sintering pearls
for zirconium oxide. The correct fill level of the sintering trays varies
depending on requirements. To prevent a delay, when positioning the
restorations to be sintered, ensure that there is sufficient support and
that the sintering pearls can move freely.
Take note of the following items when filling the sintering tray:
● Free movement of the sintering pearls
● Sufficient support for sagging restorations
● Positioning the restorations with the chewing surface facing
downwards (in contact with the sintering pearls)
● Interdental areas should be free of sintering pearls
