“The Z4 by vhf gives me the accuracy and flexibility in materials I need to accommodate more in-office workflows than we have ever seen before. Its user-friendliness and integrated compressor let us get up and mill in no time. All with incredible precision.”

Alan Jurim, DDSIntegrated Dental, Woodbury, New York

“The Z4 fits perfectly into the digital workflow, because it optimally meets the requirements for a same-day dentistry solution. It is important that intraoral scanners, design software and milling machines are seamlessly integrated.”

Dr. Ingo BareselDentist

“I have to tell you that with the Z4 you finally got everything perfect. The system is gorgeous and completely self-contained. I can’t thank you enough for letting me work with your system and I welcome the opportunity to show off and highlight this incredible vhf Z4 system.”

John A Sorensen, DMD, PhD, FACPUniversity of Washington, Seattle

“The Z4 is an easy system, and the ROI is huge, it’s ideal for both general dentists and prosthodontists who want to deliver same-day restorative care that patients appreciate.”

August de Oliveira, DDSDentist

vhf Z4 – The Future of Digital Dentistry

This video shows the most important features of the Z4 by vhf. See for yourself why dental experts all over the world call this machine “The Future of Digital Dentistry”.

The Z4: Groundbreaking

The digital workflow makes it happen: you and your patients can benefit from more pleasant treatments with first-class restorations in just one session. The Z4 is an investment that will pay off for you: high-quality restorations with maximum independence. The number of machinable block materials constantly increases as well as the number of scanners and CAD software packages that are validated with the Z4.

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

The new standard in quality

When it comes to wet machining blocks, the Z4 sets unprecedented quality standards. Fabricate glass-ceramic, PMMA, zirconia and composite restorations in mere minutes and finish highly accurate prefabricated titanium abutments.

Dental milling machine Z4 – Block clamping

Efficiency that is second to none

No external compressed air supply necessary. Only requires clean water. The block is clamped in two seconds. With the Z4, you can work with unparalleled efficiency.

Study confirms: Z4 drills screw-access channels in highest quality

A scientific study at the University of Washington proved that using the Z4, users can drill screw-access channels for hybrid implant restorations into ceramic blocks with no signif-icant difference in flexural strength compared to factory-fabricated materials, known as “meso” blocks.

These blocks are significantly more expensive, and the laboratory design method requires a more sophisticated CAD process. Thus, processing standard blocks with the Z4 means less cost for material and less material inventory necessary.
