Wash Firing
The low heat conductivity of zirconium oxide requires a Wash firing. The Wash firing ensures controlled sintering of the
ceramic onto the framework surface and enables a homogeneous bond to the fired ZirLiner. In order to achieve this, please
proceed as follows:
– Before the application of the Wash layer, clean the abutment with the steam jet.
– Mix the required IPS e.max Ceram Dentin or Deep Dentin material with the IPS e.max Ceram Build-Up Liquids allround or
soft. If a different consistency of the ceramic is desired, the liquids may also be mixed with each other at any mixing ratio.
– Apply the wash in a thin coat on the entire fired ZirLiner.
– It is important that no layering material reaches the contact surface between the abutment and the implant.
– Position the abutment on a homey-combed tray for the Wash 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 wash in a thin coat on the entire fired ZirLiner. Secure the abutment on the
polishing aid for the application of the Wash. Remove the abutment from the polishing aid and place it on a honey-combed tray for the
Wash firing. Before firing, make sure that the contact surface between the abutment
and the implant is free from contamination.
