CEREC Zirconia: Milling, sintering and glazing for dental restorations in one session

The new CEREC Zirconia workflow gives dentists a means of providing a high-performance material chairside. New devices and tried-and-tested processes make for an efficient, time-saving workflow.

CEREC Zirconia – inCoris TZI C for your chairside workflow

This is a precolored, translucent zirconium dioxide which is available in in 10 shades on the basis of the VITA Classic Shade Guide® and which requires no further liquid coloring. The material is milled or polished while dry, then fully sintered immediately afterwards. It is only then that the restoration reaches its final size. The over-sized milling facilitates a new level of milling precision leading to superb fitting restorations. The material is available in two sizes (mono L and medi S).

CEREC MC XL Premium Package, MC X and MC with dry milling option

These CEREC grinding and milling machines come equipped with a device to vacuum up the mill shavings as well as new precision tools. The new machine can be used for both wet and dry processing, one straight after the other. Dry milling saves a considerable amount of time, as the restoration does not need to be dried before sintering – thus enabling the chairside procedure. And there is no difference in quality between dry and wet milling processes. The dry dust can easily be removed using a short, integrated cleaning program. All CEREC MC XL Premium Package, MC X and MC units delivered after February 26, 2016 are equipped for full-contour zirconia finishing. All units which came into practices between May 2015 and February 2016 can be retrofitted with the "dry-ready" configuration.

CEREC SpeedFire – Finalizing in a compact sintering furnace

For sintering, there is the new CEREC SpeedFire induction furnace: the smallest, fastest sintering furnace on the market. It combines the sintering and finalizing processes (staining and glazing) in one device. Both processes are extremely quick: It takes 10 – 15 minutes to sinter and 9 minutes to glaze crowns. Small bridges need 25 minutes sintering time. Active cooling also means that the restoration is soon ready for individualization or insertion. The furnace includes a touchscreen for managing jobs as well as glazing supports on which the restorations can be fixed for glazing with CEREC SpeedPaste. Its connection to the system provides the furnace with all the necessary information on the material, color, type and size of restoration via the Sirona CAD/CAM software. Based on this information, the customer gets the right program for the restoration. An important benefit: The intuitive handling of the software makes all processes easy – there is no need for any special training or long practice sessions. The dental team can quickly be involved in all processes.

CEREC SpeedGlaze for a final high-gloss polish

To give the restoration a high-gloss finish, it can be sprayed with the new CEREC SpeedGlaze. This dries quickly and is orange in color. Visualization ensures that it is applied evenly. In the sintering furnace, the glass particles melt onto the restoration, bonding with the surface. After firing, the surface is smooth, has again taken on tooth color and is ready to be placed into the patient's mouth.

CEREC SW 4.4.1 – intuitively managed workflow

At the heart of CEREC Zirconia is the new CEREC Software 4.4.1, which automatically controls the furnace based on the size, volume and shade of the restoration. It guides users through all processes, including the start of the milling process (fast or precision milling) and the precise heat treatment cycle, which depends on the material used. The software is extremely simple to use and supports the practitioner through the entire design and fabrication process.
