Dentists who use computer-aided design/computer-aided manufacturing (CAD/CAM) systems know the chair-side technology is extremely valuable in producing dental prostheses on-site within a short time frame. With this technology, dentists can produce crowns, veneers, implants, and more from their office.

For many years, Cerec systems were the only chair-side CAD/CAM machines available. The E4D system, first released to the market in 2008, is a worthy upgrade investment.

One of the biggest advantages of the E4D system is that dentists will no longer have to dust the patient’s teeth with titanium powder before initiating the imaging process required to design restorations. The E4D system also scans images of the tooth from different perspectives, allowing for more detail, while the Cerec system takes images only once.

Even the milling process is improved on the E4D system; the computer sends instructions to the mill and is then freed for another job. The Cerec computer is freed only when the milling process is complete.
