Incisal firing
With the Incisal firing, the anatomical shape is completed and the individual esthetic appearance achieved.
The layering procedure is conducted with IPS e.max Ceram Transpa and Impulse materials. To achieve the
desired consistency, the IPS e.max Ceram Build-Up Liquid allround and soft can be used.
If a different consistency is desired, the liquids can also be mixed in any ratio.

Fire with the firing parameters for Incisal firing
Due to the thin material layer and the thus resulting limited shape change during firing, the cut-back technique also allows
to complete the restoration with one firing cycle. If a second Incisal firing is required, however, it can be conducted using
the same firing parameters.
Finishing and preparing for the Stain and Glaze firing
Before the Stain and Glaze firing, the restoration has to be finished as follows:
– Finish the restoration using diamonds and give it a true-to-nature shape and
surface structure, such as growth lines and convex/concave areas.
– If gold and/or silver dust was used to visualize the surface texture, the
restoration has to be thoroughly cleaned with steam. Make sure to remove
all gold or silver dust in order to avoid any discolouration.
