Adaptation of the emergence profile

If there is a gap between the "gingiva" (gingiva mask) and the abutment on the model with the abutment screwed down,

it can be closed by adding and ﬁring IPS e.max Ceram.

The emergence proﬁle can be adapted using tooth-shaded or gingiva-shaded materials as necessary.

Abutment Technique

Screwed-down abutment on the model with individualized incisal adaptation. The gap between the abutment and the "gingiva" requires adaptation of the emergence proﬁle.

When adapting the emergence proﬁle, the maximum layer thickness of 1.0 mm of IPS e.max Ceram must not

be exceeded.

Application of IPS e.max Ceram ZirLiner

IPS e.max Ceram ZirLiner must always be applied before the application of the IPS e.max Ceram layering materials to

achieve an optimum bond. Direct layering onto the abutment without ZirLiner may result in cracks and delamination.

– Remove the Straumann Anatomic IPS e.max Abutment from the model for the application of the IPS e.max Ceram ZirLiner.

– Do not blast the Straumann Anatomic IPS e.max Abutment with Al

, since this may damage the surface.

– Clean the abutment with the steam jet before the application of the IPS e.max Ceram ZirLiner.

– Mix the IPS e.max Ceram ZirLiner in the desired shade or gingiva shade with the respective IPS e.max Ceram ZirLiner Build-

Up Liquid to a creamy consistency.

– For shaded abutments, use IPS e.max ZirLiner clear.

– If a different consistency is desired, IPS e.max Ceram Build-Up Liquid (allround or soft) as well as the IPS e.max Ceram Glaze

and Stain Liquids (allround or longlife) may be used. The liquids may also be mixed with each other at any mixing ratio.

– Cover the areas to be adapted with ZirLiner. If necessary, brieﬂy vibrate until an even, greenish colour effect is achieved. If

the colour appears too pale, the layer is too thin.

– For more intensively shaded areas, four IPS e.max Ceram Intensive ZirLiners (yellow, orange, brown, incisal) are available.

– It is important that no ZirLiner reaches the contact surface between the abutment and the implant.

– Conduct the ZirLiner ﬁring on a honey-combed ﬁring tray.

– After ﬁring, the IPS e.max Ceram ZirLiner should exhibit a layer thickness of approx. 0.1 mm.

– 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.
