Apply IPS e.max Ceram ZirLiner Gingiva to all the areas of the framework onto which IPS e.max ZirPress
Gingiva will be pressed.
Framework Preparation and Application of ZirLiner
The framework is prepared according to the “Framework Preparation” notes (page 14ff). After preparing the framework,
the following procedure has to be observed in the Gingiva technique:
– Before ZirLiner is applied, clean the framework with the steam jet.
– The framework must not be blasted with Al 2 O 3 , since this would damage the surface.
– IPS e.max Ceram ZirLiner must always be applied prior to the wax-up in order to achieve a sound bond as well as an in-
depth shade effect and fluorescence.
– Direct press-on procedures on zirconium oxide frameworks without using ZirLiner results in a poor bond and may lead to
cracks and delamination. Therefore, ZirLiner must be applied to all the areas onto which the restoration will be pressed.
– The IPS e.max Ceram ZirLiner in the corresponding shade is also applied before the Gingiva pressing procedure on all
areas of the framework which will be veneered after pressing the gingival parts.
– Mix the IPS e.max Ceram ZirLiner with IPS e.max Ceram ZirLiner Build-Up Liquid to a creamy consistency.
– 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.
– Apply the different IPS e.max ZirLiners on the entire framework, paying special attention to the margins. If required, the
restoration may be vibrated until an even shade 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.
– After that, the applied ZirLiner is briefly dried and fired.
– After firing, the IPS e.max Ceram ZirLiner should exhibit a layer thickness of approx. 0.1 mm.
Apply IPS e.max ZirLiner Gingiva in those areas to which IPS e.max ZirPress Gingiva will be
subsequently pressed. Coat non-involved outer surfaces with IPS e.max Ceram ZirLiner in the
respective tooth shade and fire. Restoration after ZirLiner firing
