Technique
1 st /2 nd Dentin and Incisal firing
For the application of the layering materials on the fired Wash, observe the following procedure:
– Secure the Straumann ® Anatomic IPS e.max ® Abutment with the fired Liner on the model using the screw.
– Mix the required IPS e.max Ceram layering materials, i.e. Dentin, Incisal and Effect, 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.
– Seal the screw cavity before layering so that no material may enter.
– Subsequently, layer the IPS e.max Ceram layering materials. Observe the maximum layer thicknesses.
– Loosen the screw after layering and carefully remove the abutment from the model.
– Before firing, the contact surface between the abutment and the implant as well as the screw cavity must be
checked. They must be absolutely free of layering material so that the accuracy of fit is not compromised.
– Position the restoration on 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.
– If a second firing is required, it can be conducted using the same parameters.
Layer the IPS e.max Ceram layering materials.
Before firing, make sure that the contact surface between the abutment and the implant and the screw cavity are free from contamination.
