Stain and characterization firing with IPS Empress Universal Shade and Stains
After the restoration has been cleaned, the stain and characterization firing is conducted.
The following working procedure should be observed:
– Extrude IPS Empress Universal Shade and Stains from the syringe and mix thoroughly.
– Thin the material to the desired consistency using IPS Empress Universal Glaze and Stain Liquid.
– For better wetting of the stains, a small quantity of IPS Empress Universal Glaze and Stain Liquid may be slightly rubbed
into the surface.
– Apply the mixed Shade material directly onto the surface.
– Intensify the corresponding dentin shade in the cervical and central crown thirds using IPS Empress Universal Shade.
– Refrain from applying excessively thick or thin material layers.
– You can achieve more intensive shades by repeating the staining and firing procedures, rather than by applying thicker
layers.
– To imitate the incisal area and translucency in the incisal third, use IPS Empress Universal Shade Incisal.
– Design individualized affects and characterizations using the Stains material.
– Apply the Stains thinly and in a controlled manner using a brush.
The dentin body is intensified using IPS Empress Universal Shade.
Individualized effects and characterizations are designed using IPS Empress Universal Stains.
The incisal area is imitated using IPS Empress Universal Shade Incisal.
