Stain and Characterization Firing

The following paragraphs will explain the most important steps for staining and characterizing with IPS e.max Ceram

Essence and Shade. For further information on the nano-fluorapatite layering ceramic and its processing, please refer to

the IPS e.max Ceram Instructions for Use.

– IPS e.max Ceram Shades are ready-to-use stains in syringes.
– IPS e.max Ceram Essence are intensively shaded powdered stains which are mixed with

IPS e.max Ceram Glaze and Stain Liquid.

– IPS e.max Ceram Glaze Paste is a ready-to-use glaze paste supplied in a syringe.
– IPS e.max Ceram Glaze Spray is a ready-to-use glaze spray.
– IPS e.max Ceram Glaze Powder is a glazing material in powder form to mix with

IPS e.max Ceram Glaze and Stain Liquid.

Before the Stain and Characterization firing, the restoration must be free of dirt and grease.

Any contamination after cleaning must be prevented. The following steps must be observed:

– For better wetting of the stains, a small quantity of IPS e.max Ceram Glaze and Stain Liquid may be slightly rubbed into

the restoration surface.

– Mix the paste or powder with the IPS e.max Ceram Glaze and Stain Liquids allround or longlife to the desired

consistency.

– More intensive shades are achieved by several staining procedures and repeated firing, not by applying thicker layers.
– To imitate the incisal area and translucency in the incisal third, IPS e.max Ceram Shade Incisal may be used.
– The cusps and fissures can be individualized using Essence.
– Conduct the Stain and Characterization firing using the indicated firing parameters.

Coat the surface with a small amount of the IPS e.max Ceram Glaze and Stain Liquid to
enhance the wettability of the surface.

Apply IPS e.max Ceram Shade Incisal to imitate the incisal area.

Individually design cusps and fissures using Essence.

Conduct the Stain and Characterization firing on a honey-combed tray using

the indicated firing parameters.
