Dentin and Incisal firing
Please refer to the Instructions for Use of the veneering ceramic system you are using for detailed information. In order to achieve
highly esthetic restorations, please observe the following procedure:
Before layering, apply IPS Model Sealer or a customary plaster sealer on the model and allow it to dry. After that, isolate the
corresponding areas using IPS Ceramic Separating Liquid or a comparable ceramic separating liquid.
Place the framework on the model and make sure it is correctly positioned.
Mix the required veneering materials with the respective liquids.
Then layer the materials according to the layering diagram and the guidelines of the manufacturer of the veneering ceramic.
Observe the necessary layer thickness. We recommend using IPS e.max Ceram Deep Dentin for the veneering of Zenostar T to
ensure that the brightness value of the restoration is maintained.
Carefully remove the restoration from the model and supplement the contact points.
Do not apply excessive suction and prevent the restoration from drying out.
Before firing, all the interdental areas must be separated down to the framework using a scalpel.
Position the restoration on the firing tray and fire it using the stipulated firing parameters.
Isolate the model and place the Zenostar MO framework in
the correct position.
Complete the layering procedure with Incisal and Transpa materials. Completely separate the interdental areas prior to firing.
Build up the tooth shape using Dentin materials.
