Layer the emergence profile using Deep Dentin and/or Gingiva. Place the abutment on a honey-combed firing tray for the Dentin firing.
Dentin firing
For the application of the layering materials on the fired ZirLiner, observe the following procedure:
– Secure the Straumann ® Anatomic IPS e.max ® Abutment with the fired Liner on the model.
– Mix the required IPS e.max Ceram layering materials Deep Dentin or Gingiva with the Build-Up Liquids allround or soft. If a
different consistency of the ceramic is desired, the liquids may also be mixed with each other at any mixing ratio.
– Subsequently, layer the emergence profile. Observe the necessary layer thicknesses.
– Loosen the screw and carefully remove the abutment from the model.
– Before firing, the contact surface between the abutment and the implant must be checked. It must be
absolutely free of layering material so that the accuracy of fit is not compromised.
– Position the restoration on a honey-combed tray and fire it according to the stipulated firing parameters.
– Remove the restoration from the furnace after completion of the firing cycle (wait for the acoustic signal of the furnace).
– Allow the objects to cool to room temperature in a place protected from draft.
– Do not touch the hot objects with metal tongs.
