EASE CLASS

E3: Aligner manufacturing in assembly-line style.

The specialist in the processing of thermoformed dental splints.

The new E3 enables you to automate the precision trimming of occlusal appliances. You can expect the very best results in the shortest time. The machined fabrication also ensures a consistently high quality.

The E3 is simple to commission and operate, and fits seamlessly into your workflows. Our in-house developed trimcam software automatically recognizes the trimline on which the occlusal appliance is milled out from the available planning data. So, you’ll get started right away.

True to the motto: unpack, connect, start milling!

Highlights

For more comfort in aligner and splint production

With a machine weight of only 25 kg and no use of compressed air, the compact E3 offers maximum flexibility in terms of the installation site. Meticulous attention has been paid to the details: for example, no separate extraction system is required – thanks to the practical collection tray for chips.

100% developed and manufactured in Germany, the E3 impresses with its precise results and outstanding reliability – not only for aligners, but also for bite splints, grinding splints and other splints, including sports mouthguards. Despite its compact design, the interior of this machine contains only high-quality industrial components.

Saves time and work

Benefit from the machining of aligners in under 60 seconds. This saves you a lot of time compared to manual production – and on top of that you gain the high precision of CNC production.

The tool-free clamping system further simplifies your work processes. This quick workpiece change enables you to produce entire series of aligners quickly and easily.

With trimcam to the perfect aligner

The trimcam software developed in-house at vhf enables you to fabricate your dental splints conveniently and easily. The trimcam workflow supports you from the moment you import the 3D data on the dental arch model from your CAD application. From this data, trimcam automatically calculates the trim line you can apply to further customize as needed. This step is followed by preparation for 3D printing of the dental arch model and precision milling of the thermoforming sheet thermoformed by this model.
