ZirLiner firing
Before ZirLiner is applied, the framework must be free of dirt and grease. Avoid any contamination after
cleaning. Observe the following procedure.
– The IPS e.max ZirLiners are only suitable for the application on IPS e.max ZirCAD and other zirconium oxide frameworks.
– IPS e.max Ceram ZirLiner must always be applied prior to veneering in order to achieve a sound bond as well as an in-
depth shade effect and fluorescence.
– Direct layering on ZirCAD framework without using IPS e.max Ceram ZirLiner results in a poor bond and may lead to
delamination.
– For unshaded frameworks, use the IPS e.max Ceram ZirLiners 1-4. If the frameworks are shaded, the
IPS e.max Ceram ZirLiner clear is applied.
– Mix the IPS e.max Ceram ZirLiner in the corresponding shade with the respective liquid to a creamy consistency.
– If a different consistency is desired, the IPS e.max Ceram Build-Up Liquids (allround or soft) and the Glaze and Stain
Liquids (allround or longlife) may be used. The liquids may also be mixed with each other at any mixing ratio.
– Apply ZirLiner on the entire framework, pay special attention to the margins. If required, the restoration may be vibrated
until an even, greenish colour effect is achieved. If the colour appears too pale, the layer is too thin.
– For more intensively shaded areas, 4 IPS e.max Ceram Intensive ZirLiners (yellow, orange, brown and incisal) are available.
– After that, the applied ZirLiner is briefly dried and fired.
– The IPS e.max Ceram ZirLiner should have a layer thickness of approximately 0.1 mm after firing
– If ZirLiner is to be individually characterized after the Margin firing, IPS e.max Ceram Essence is suitable for this purpose.
Given the lower firing temperature of Essence, characterization prior to Margin firing is not possible.
Mix the corresponding IPS e.max Ceram ZirLiner with ZirLiner Liquid to a creamy consistency. Cover the entire framework with the mixed ZirLiner. Make sure that an even, greenish
colour effect is achieved.
Conduct the ZirLiner firing on a honey-combed firing tray using the stipulated firing parameters.
