Finish the restoration with diamonds and give it a true-to-nature shape and surface structure.
Preparing for Stain and Glaze firing
Before the Stain and Glaze firing, the restoration has to be prepared as follows:
– Finish the restoration using diamonds and give it a true-to-nature shape and surface structure, such as growth lines and
convex/concave areas.
– Areas which should exhibit a higher gloss after Glaze firing can be smoothed out and prepolished using silicone disks.
– If gold and/or silver dust was used to visualize the surface texture, the restoration has to be thoroughly cleaned with
steam. Make sure to remove all gold or silver dust in order to avoid any discolouration.
Stain and Glaze firing
Stain firing is conducted with IPS e.max Ceram Essence and/or IPS e.max Ceram Shades, while Glaze firing is carried out
with IPS e.max Ceram. Depending on the situation, the Stain and Glaze firings may be conducted together or separately
one after the other. The firing parameters are identical.
In order to achieve an even gloss during Glaze firing of cut-back restorations veneered with IPS e.max Ceram, two
different procedures are possible:
Standard
(high-gloss appearance)
– Prepolish unlayered areas (IPS e.max ZirPress) using
rubber wheels.
– Rub the surface with moist ceramic in order to improve
the wetting properties of the surface.
– Clean the restoration with steam
– Apply IPS e.max Ceram Glaze(Paste, Powder, or Spray)
on the entire restoration.
Option
(true-to-nature appearance)
– Prepolish unlayered areas (IPS e.max ZirPress) using
rubber wheels.
– Rub the surface with moist ceramic in order to improve
the wetting properties of the surface.
– Clean the restoration with steam
– Apply IPS e.max Ceram Glaze (Paste or Powder) only on
unlayered areas (IPS e.max ZirPress).
– Use Self-Glaze for veneered areas.
