Subsequent adjustments
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, blast the areas to be
adjusted with Al 2 O 3 (Type 100) at max. 0.5 bar pressure and thoroughly clean the restoration using the steam jet.
– Mix IPS Empress Add-On 770 °C / 1418 °F with IPS Empress Esthetic Veneer Build-Up Liquid 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.
