VHF Z4 – the perfect chairside CNC milling machine

VHF Z4 – the chairside milling machine for milling glass-ceramics, PMMA, zirconia, and composite restorations

The VHF Z4 is a high-end, 4-axis milling machine designed for chairside solutions. The VHFf Z4 has been developed according to the latest quality standards. When it comes to wet milling blocks, the Z4 sets unprecedented quality benchmarks. Fabricate glass-ceramics, PMMA, zirconia, and composite restorations in just a few minutes, and finish highly precise prefrabricated titanium abutments.

The VHF Z4 features an integrated workflow with 3Shape, Exocad, and other (open-source) software systems. By integrating the Z4 into your practice, you have everything in one smooth workflow: scanning, designing, and milling.

The new standard in quality

When it comes to wet milling of blocks, the Z4 sets unprecedented quality standards. Produce glass-ceramic, PMMA, zirconia, and composite restorations in just a few minutes, and create highly precise prefabricated titanium abutments.

Unmachted efficiency

No external compressed air required, only clear water. The block is clamped in just two seconds. With the Z4, you can work with unparalleled efficiency.

The VHF Z4 fits perfectly into your digital workflow
The digital workflow makes it possible: you and your patients benefit from more comfortable treatments with first-class restorations in just one session. The Z4 is an investment that pays for itself: high-quality restorations with maximum independence. The number of block materials that can be processed is constantly increasing, as well as the numbmer of scanners and CAD software packages validated for use with the Z4.

From intraoral scanner to milling machine: users work with a single interface and only need to familiarize themselves with one software package. This is the convenience of fully integrated workflows.
