Highlights

Chairside production is so easy

The new E4 makes it so easy for you to get started with chairside production of dental restorations, and gives you maximum freedom. Combine the E4 with your preferred intraoral scanner, any CAD software and materials that are appropriate for your individual patients. The E4 is the heart of your workflow and produces the perfect restoration for you.

The integrated CAM software enables you to get started right away!

The all-rounder for blocks

The E4 has many talents. Wet grind glass ceramics or composites with ceramic content and dry mill materials such as zirconia and PMMA.

A small change with a big effect. Benefit from easy switching: Insert the tank for wet processing or the optional container for machining dust and start processing high-quality restorations. A special filter mat in the liquid tank ensures that the tank is free of chippings.

No compressed air with the innovative technology

One great innovation of the E4 is that it does not use compressed air: The E4 requires neither an external compressed air connection nor an integrated compressor, which is only possible with our patent-pending airtool.

The airtool turbine blades use the speed of the high-frequency spindle to generate a powerful air flow, which keeps the workpiece free from dust and chippings. They are removed by vacuum from a dust collector.

Wet grinding

The purewater Technology ensures that the closed liquid circuit in the machine requires no grinding additives. For you, this means easy disposal and even lower running costs.

Dry milling

The optional dry container enables you to mill materials such as zirconia, PMMA and various composites with your E4 with no cooling water or compressed air.
