Preparing for staining
Before the stain and characterization firing, the restorations must be free
of dirt and grease. Avoid any contamination after cleaning.
Observe the following procedure.
– Clean the restoration with ultrasound in a water bath or blast with
Al 2 O 3 at 0.5 bar pressure (Caution: abrasive) and clean under running
water or using the steam jet.
– Certain blasting devices require different settings for the intended
blasting procedure.
Stain and glaze firing using IPS Empress Universal Shade and Stains
Once the restoration has been cleaned, the stain and characterization firing is conducted. Observe the following working
procedure:
– Extrude IPS Empress Universal Shade or 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 unto the surface.
– Intensify the corresponding dentin shade in the cervical and central crown thirds using IPS Empress Universal Shades.
– Excessively thick or thin material layers should be prevented.
– More intensive shades are achieved by repeated staining, 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.
