The new CEREC Zirconia makes chairside, single-visit zirconia restorations possible.

At this year’s Chicago Dental Society Midwinter Meeting, Sirona announced the combination of a trusted restorative material and the leading innovator in CAD/CAM dentistry.

CEREC by Sirona has long been an industry leader in single-visit, CAD/CAM dentistry. Zirconia has long been sought-after by many dentists as a high-performance restoration material.

Now, they can be used together. Along with Sirona, Patterson Dental announced the release of CEREC Zirconia in the U.S. and Canada, enabling dental practices to provide their patients with single-visit chairside zirconia restorations.

“CEREC Zirconia is another innovation that helps our clients do more for their patients and their practice,” said Patterson Dental CEO Paul Guggenheim. “Single-visit zirconia restorations with CEREC will positively impact the experience of every patient in every practice that adopts them.”

Along with the introduction of CEREC Zirconia came the introduction of the CEREC SpeedFire furnace. Practices can both sinter and glaze with the CEREC SpeedFire to create full-contour zirconia restorations in one session.

For sintering, the SpeedFire is the smallest and fastest furnace on the market—sintering a crown in typically 10-15 minutes —making the strength of full-contour zirconia possible for chairside treatment. And, if needed, a glaze can be applied with the CEREC SpeedGlaze and then fired in just a few minutes in the CEREC SpeedFire. Thanks to this speedy, space-saving tool, the restoration is then ready to be placed into the patient’s mouth.

With the CEREC Single-Visit Zirconia workflow, dental teams can create, sinter and glaze a full-contour zirconia crown in as little as 70 minutes.

CEREC Zirconia highlights

Zirconium oxide is a high-performance material in great demand, which CEREC combines with a workflow optimally matched to the material. Zirconium oxide’s high degree of flexural strength and biocompatibility allow tooth-conserving preparations for fully anatomical restorations. The result: faster, easier, more economical zirconium oxide restorations than ever before.

Other benefits of CEREC Zirconia include:

• Minimal invasiveness. Full-contour zirconia restorations require a lower wall thickness and less reduction in tooth structure for full strength.

• Strength. Full-contour zirconia ensures that you and your patients receive long-lasting restorations.

• Perfect fit. A 25 percent larger pre-sintered state yields highly precise margins and occlusal surfaces.

What makes CEREC Zirconia truly special is the combination of different innovations. It’s the only combination that allows a single-visit treatment with full-contour zirconia, and the innovation that comes along with every CEREC.

So, what does CEREC Zirconia bring to the dental practice?

Everything under control

With CEREC Zirconia, you are 100 percent in control of creating restorations and ensuring their quality. The CEREC Zirconia workflow allows you to step in before the restoration is glazed or inserted. That saves time, may save the patient another appointment, and prevents arduous grinding and costly intraoral polishing.

Tooth-conserving preparation

The high strength of CEREC Zirconia benefits both dentist and patient. Restorative treatment is even possible in confined spaces, and when replacing metal restorations, hardly any of the old preparations have to be removed. Preparations preserve tooth substance and can be cemented conventionally when fitted.

Safety in strength and fitting accuracy

CEREC Zirconia is milled oversized and then densely sintered in the CEREC SpeedFire to its final size. This leads to precise edges and a detailed occlusion. A subsequent glaze firing brings the restoration to a high gloss. CEREC Zirconia stands for high strength – thin wall thicknesses can be processed. Chipping is eliminated and, of course, bridges can also be made.

Efficient and simple workflow

Thirty years of CAD/CAM experience now make it possible to bring full-contour zirconia restorations into the practice. The pre-shaded CEREC Zirconia material (colors A1–D3 of the VITA Classical A1–D4^® color system), dry milling with the CEREC grinding and milling unit, and the extremely short sintering cycles of the new CEREC SpeedFire – everything is designed for time savings and simplicity.
