Stain and Glaze firing
The IPS Empress Universal Shades/Stains and Glaze have been especially developed for the ceramic materials of the
IPS Empress System from Ivoclar Vivadent. They can be used for the following techniques:
– IPS Empress Esthetic
– IPS Empress CAD
– IPS Empress 2 Layering Technique
– IPS Empress 2 / IPS Eris for E2 Layering Technique
After cleaning the restoration, the Stain and Glaze firing is carried out. Basically, there are two options:
Optional
Version A – 2-in-1 Technique
First, the glaze paste is applied, followed by the stains, which are applied on the unfired glaze layer.
Step 1 – Application of the glaze material:
– Extrude IPS Empress Universal Glaze from the syringe and thin the material to the desired consistency using IPS Empress
Universal Glaze and Stain Liquid.
– Apply the glazing material on the entire outer surfaces of the restoration.
– The glazing material must not come into contact with the inner aspects of the restoration.
– Too thin glazing material layers result in an unsatisfactory gloss.
– Avoid pooling and too thick glazing material layers.
Step 2 – Application of Shades/Stains:
– 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.
- Apply the mixed Shade/Stains material directly into the unfired glazing material layer.
– Intensify the corresponding dentin shade in the cervical and occlusal areas using IPS Empress Universal Shades.
– To imitate the incisal area and translucency in the incisal third, use IPS Empress Universal Shade Incisal.
– Apply individualized effects and characterizations using IPS Empress Universal Stains materials.
After staining and glazing, the Stain and Glaze firing is conducted in a compatible ceramic furnace (e.g. Programat ® P500).
The following points should be observed when placing the restoration in the furnace and setting the firing parameters:
– Place the restorations on the metal pins using a small amount of IPS Object Fix and position them on the honey-comb
firing tray .
– As an alternative, the restorations can be supported with a firing pillow. Due to their lower position in the firing
chamber, the restorations are exposed to less heat. Therefore, in order to achieve the desired gloss, the holding time
must be extended to up to 2 minutes.
