1 st Margin firing (optional)
A ceramic shoulder is applied to the reduced premolar bridge abutment after the ZirLiner firing. Observe the following
procedure:
– Before the ceramic shoulder is applied, cover the model die with IPS Margin Sealer and allow it to dry. After that, isolate
the shoulder areas using IPS Ceramic Separating Liquid.
– Place the framework on the die and make sure it is correctly positioned.
– Subsequently, mix IPS e.max Ceram Margin in the desired shade with the corresponding Margin Build-Up Liquid
(allround or carving) and apply in drop-shaped increments.
– For more intensively shaded areas, 4 Intensive Margin materials (yellow, yellow-orange and orange-pink) are available.
– Contour the Margin material as desired and dry.
– Carefully remove the framework with the applied and dried shoulder material from the die, place it on a honey-combed
tray and fire.
Isolate the die and apply the Margin material on the entire shoulder preparation.
Do not apply the Margin material too thinly or with a concave shape. Apply the Margin material in drop-shaped increments.
Firing parameters for the ZirLiner firing (note the temperature control)
Do not apply any layering materials on unfired ZirLiner, since this will lead to delamination of the layering
ceramic. Before the actual layering is commenced, the ZirLiner must be fired.
