Interface

Posterior ceramic restorations require dental technicians to exhibit considerable expertise with regard to both anatomy and function. These quality aspects are very difficult to check when building up posterior crowns or bridges, as each firing will result in more contraction of the ceramic material.
The Interface technique presents a solution to this problem. The wax-up is performed directly on the framework, and the subsequent ceramic pressing step is completed in the pressing furnace as a one-to-one transfer without any dimensional changes.
Interface ingots are available in 5 shades to produce restorations in all 16 Vita shades. The opaques or liners of the Pulse system shine through from the depth of the restoration, forming the chromatic base for a natural-looking veneer. The translucent properties of the Interface dentins are engineered such that you can press a complete ceramic restoration from a single material. Where the veneer is thinner, e.g. in the cervical or occlusal areas, the fired base material increases the chromatic effect. Where the ceramic veneer is thicker, e.g. near cusps or in the proximal region, incident light will be scattered and appears brighter and less chromatic. The fluorescent Pulse stains are used to perform a final customization.

Application and characteristics
There is currently no better way to produce high-quality ceramic shoulders, perfectly functional occlusal surfaces or emergence profiles for implant-supported restorations. One of the most useful attributes of the pressable ceramic material is its high surface density that reduces plaque deposits in the cervical regions and protect the gingival tissues from product-related irritation.
