Direct firing of IPS e.max Ceram
IPS e.max Ceram offers the possibility to directly veneer the Straumann ® Anatomic IPS e.max ® Abutment. The veneered
abutment is intraorally screwed down with the abutment and the screw cavity sealed with composite.
When firing IPS e.max Ceram on the Straumann ® Anatomic IPS e.max ® Abutment, the following maximum layering
thicknesses 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 as well as a true-to-nature shade effect and in-depth translucency.
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 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 veneered 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.
