Practical Use; Correctly Loading The Furnace - Ivoclar Vivadent Programat CS6 Operating Instructions Manual

2. Application

2.3. Practical use

The operating procedure will be explained with the help of two examples: one Ivoclar Vivadent program and one individual
program. The correct loading of the firing chamber is described beforehand.
If a restoration has fallen into the firing chamber, make sure to remove it by means of the service position before
starting the next program. Otherwise, the insulation can get damaged.

2.3.1 Correctly loading the furnace

Loading for sintering programs
Up to three units may be positioned on the object tray in the firing
chamber. Make sure that the objects do not touch each other in
order to prevent them from sintering together. The objects must be
positioned within the circumferential groove of the object tray. For
more detailed information, please refer to the Instructions for Use of
the respective material.
To achieve optimum sintering results, the objects should be placed
on their occlusal or labial surface (not on the cervical margin).
Massive pontics in particular must rest on the object tray during the
sintering process.
Exclusively use the supplied special tweezers to place the objects on the object tray in the firing chamber. Do not
use any additional firing trays.
There are special sinter programs with integrated predrying process for wet machined IPS e.max ZirCAD
restorations. Additional predrying is not necessary.
For wet machined zirconia restorations, predrying "ZrO
process must not be selected.
Remove the objects from the furnace at the end of the sintering
program and allow the objects to cool on the cooling tray (a).
Exclusively use the supplied special tweezers for this purpose.
Do not remove the hot objects with firing tongs with metal surfaces!
Do not place the hot objects directly on the cooling tray!
Cooling may be too fast in certain areas, which may result in cracks or tears in the objects.
