Subsequent adjustment
After completion, additional adjustment (e.g. contact points) may become necessary. For that purpose,
IPS Empress Add-On 770 °C/1418 °F is available.
Processing:
– Before the adjustment, the restoration must be free from dirt and grease. For that purpose, thoroughly clean the
restoration using the steam jet.
– Mix IPS Empress Add-On 770 °C / 1418 °F to a workable consistency. Make sure that the add-on material and liquid are
evenly mixed so that an optimum firing result can be achieved.
– Apply the mixed add-on material on the cleaned, desired areas using a brush and slightly blot them with an absorbent
cloth.
– Position the adjusted restoration on the firing tray and fire in the ceramic furnace.
– After firing, manually polish the supplemented areas to a high gloss.

Firing parameters for the corrective firing
Place the objects on the honey-comb firing tray and start
the firing program
After glazing and staining, the glaze and stain firing is conducted in a compatible ceramic furnace (e.g. P500).
The following points should be observed when placing the restoration in the furnace and setting the firing parameters:
– Support inlays, onlays, and partial crowns with a firing pillow and place them on a honey-comb firing tray.
– Place veneers as well as anterior and posterior crowns on metal pins and position them on the honey-comb firing tray.
– As an alternative to the firing pillow and to better secure the restoration
on the metal pins (particularly with veneers), a small amount of
IPS Object Fix may also be used.
– Restorations supported with a firing pillow on the honey-comb tray are
exposed to less heat due to their lower position in the firing chamber.
Therefore, in order to achieve a true-to-nature gloss, it is recommended
to extend the holding time from 1 minute to 2 minutes.
– Make sure that the firing pillow is regularly replaced in order to prevent
contamination. Keep firing pillows used for all-ceramic materials
separated from those for metal-ceramics to avoid cross-contamination.
