Careful bonding of porcelain is key to making a zirconia restoration last and to greatly reduce or eliminate debonding of ceramic off of zirconia. Several companies have zirconia "liners" but I have found the e.max zirliner to have the best result for me. This liner has flourescense, translucency, base color & gives a superb bond to zirconia with its high firing temp. Here are some details:

What is the purpose of the IPS e.max Ceram ZirLiner?
IPS e.max Ceram ZirLiners are translucent. Their three major purposes are as follows:
1. They enable a strong, homogeneous bond with the zirconium oxide framework.
2. They provide the white, non-coloured zirconium oxide frameworks with chroma, an in-depth effect, and a shaded character
without increasing their opacity.
3. They also provide the non-fluorescent zirconium oxide framework with a natural fluorescence, thus enabling the fabrication of lifelike restorations.


Can IPS e.max ZirCAD frameworks also be pressed-over and/or veneered without IPS e.max Ceram ZirLiner?
A suitably shaded IPS e.max Ceram ZirLiner must always be applied before waxing up. The IPS e.max Ceram ZirLiner generates an
outstanding bond and gives the restoration an effect of depth with regard to colour and fluorescence.

Why is the IPS e.max Ceram ZirLiner powder green and how should it be applied?

Since zirconium oxide is white and, therefore, shows a poor contrast to tooth-coloured and/or white powders, the IPS e.max ZirLiner was given
an identification colour to render its application more simple and efficient. The IPS e.max Ceram ZirLiner consists of a very fine powder and
appears somewhat thick due to the dense packing of the grains. Make sure that the material is applied in an even, greenish coat. If the shade
is too pale, the layer is too thin. After firing, however, the ZirLiner demonstrates a layer thickness of approximately 0.1 mm.
