Technique
Glaze firing
Stain firing is conducted with Essence and/or Shades, while glaze powder or paste is used for Glaze firing. Depending on the
situation, the Stain and Glaze firings may be conducted together or separately one after the other. The firing parameters are
identical.
The restoration must be free of dirt and grease. Avoid any contamination after cleaning the restoration with ultrasound in a
water bath or steam jet. With this firing, final adjustments of contact points are also possible. The following steps must be
observed:
– For better wetting of the Stains and Glaze, a small amount of Glaze and Stain Liquid can be applied on the surface.
– Mix the Glaze paste or powder with the IPS e.max Ceram Glaze and Stain Liquids allround or longlife to the desired con-
sistency.
– If more intensive shades are desired, they are achieved by several staining procedures, not by applying thicker layers.
– The cusps and fissures can be individualized using Essence.
– If shade adjustments are required, Shade materials can be used.
– Apply the glazing material in an even layer on the entire restoration.
– For the adjustment of the contact points, mix e.g. IPS e.max Ceram Incisal and Add-On Incisal in a 1:1 ratio. Polish the
adjusted areas to a high gloss after firing using silicone polishers.
– Before firing, the contact surfaces between the abutments and the implant must be checked. It must be
absolutely free of Glaze and Stains so that the accuracy of fit is not compromised.
– Position the restoration on a honey-combed tray and fire it according to the stipulated parameters for the Glaze firing.
– Remove the restoration from the furnace after completion of the firing cycle (wait for the acoustic signal of the furnace).
– Allow the objects to cool to room temperature in a place protected from draft.
– Do not touch the hot objects with metal tongs.
Apply the Glaze in an even layer. Apply characterizations using Shades and Essence
Supplement the contact points using a 1:1 mixture. Conduct the Glaze firing on a honey-combed tray with the stipulated firing parameters.
Before firing, make sure that the contact surface between the abutment and the implant is
free from contamination.
