Ivoclar Vivadent Programat S1 sintering programs
Prior to sintering, allow moist restorations to dry for a sufficiently long time depending on
their size (see Table on page 17).
Restorations that are sintered while still being moist may become damaged during the
sintering process due to the high heating rate.
For the sintering process in the Programat S1, the following points should be observed:
Do not use ZrO
2
sintering beads in the Programat S1.
The sinter tray can be completely filled with restorations. Make sure that the restorations do
not touch each other.
Simultaneous sintering of single-tooth restorations, bridges and constructions with a sinter
support structure is possible.
Selecting the correct program is essential.
Provide even support for the restorations to ensure deformation-free sintering results.
Bridge constructions should not exclusively be supported by the abutment crowns on either side. Preferably provide support to
the pontics. The abutment crowns do not necessarily have to be supported by/be in contact with the sinter tray.
Bridge constructions in particular are best arranged in concentric circles on the sinter tray. Important!
Do not place any restorations over the separation (groove) on the sinter tray.
Place the loaded sinter tray in its intended position in the centre of the sintering chamber of the Programat S1 using a sinter
tray fork.
