Check of the restoration on the model. The fired emergence profile must rest flush against
the gingiva. finishing the layered areas with fine-grain diamonds and rubber polishers.
Finishing and preparing for the Stain and Glaze firing
Before the Stain and Glaze firing, the abutment has to be finished as follows:
– Check the restoration on the model. The fired emergence profile must be designed in such a way that it rests flush
against the "gingiva" without exerting pressure.
– It is important that the contact surface between the abutment and the implant is not finished in any way. The polishing
aid can be used for finishing.
– If necessary, the emergence profile can be finished using fine-grain diamonds and rubber polishers.
– Prepolish tapered areas with a rubber polisher so that a very smooth transition to the abutment is achieved.
Apply Glaze and/or Stains on the fired areas. Conduct the Glaze firing on a honey-combed tray with the stipulated firing parameters.
Before firing, make sure that the contact surface between the abutment and the implant is
free from contamination.
Glaze firing
The abutment must be free of dirt and grease prior to the Glaze firing. Any contamination after cleaning must be prevented.
The following steps must be observed:
– Mix the paste or powder with the IPS e.max Ceram Glaze and Stain Liquids allround or longlife to the desired consistency.
– The shade of the emergence profile can be individually designed using IPS e.max Ceram Essence and Shade materials.
– Apply the Glaze and Stains layer thinly using a brush.
– Before firing, the contact surface between the abutment and the implant must be checked. It must be
absolutely free of Glaze and Stains so that the accuracy of fit is not compromised.
– Position the restoration on a honey-combed tray and fire it according to the stipulated parameters for the Glaze firing.
– 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.
