CEREC

What is CEREC?

CEREC (CERamic REContstruction) is a dental restoration product that allows a trained dental practitioner produce an indirect ceramic dental restoration using a variety of computer assisted technologies, including 3D photography and CAD/CAM. With CEREC, teeth can be restored in a single sitting with the patient, rather than the multiple sittings required with standard techniques. Additionally, with the latest software and hardware updates, crowns, veneers, onlays and inlays can be prepared, using different types of ceramic material.

The Benefit to you:

• One visit dentistry

• No temporaries

• No second visit

• Natural Appearance (no grey lines at the gumline)

• Variety of metal free restorations to choose from
  CAD/CAM Technology with highly accurate results

• Design and fabrication by your dentist at chairside

Technology

The cavity preparation is first photographed and stored as a three dimensional digital model and proprietary software is then used to approximate the restoration shape using biogeneric comparisons to surrounding teeth. The practitioner then refines that model using 3D CAD software. When the model is completed, a milling machine carves the actual restoration out of a ceramic block using diamond head cutters under computer control. When complete, the restoration is bonded to the tooth using a resin.

History

The system is manufactured by Sirona Dental Systems in Bensheim, Germany . 1980 Development of the CEREC method at the University of Zurich W. Mörmann, M. Brandestini). 1985 Treatment of the first patient with CEREC (University of Zurich, material: VITABLOCS Mark I). 1986 Siemens acquires the license to market and further develop the CEREC equipment. 1987 CEREC 1 is introduced (chief indication: single and dual-surface inlays; material: VITABLOCS Mark II). 1990 International CEREC Symposium at the University of Zurich. 1991 Hydraulic machining drive replaced by an electronically controlled motor. 1994 CEREC 2 is introduced (range of indications: inlays, onlays, veneers). 1996 CAD/CAM Symposium to mark a decade of CEREC (University of Zurich). 1997 Sirona was formed as the result of the sale of the Dental Division of Siemens AG. 1997 CROWN 1.0 program for producing full-ceramic posterior crowns. 1998 Second material manufacturer partnership is formed (lvoclar, ProCAD). 1998 CROWN 1.11 program for producing posterior and anterior restorations. 2000 CEREC 3 is introduced (compact Windows-based CAD/CAM system). 2000 Third material manufacturer partnership is formed (3M Paradigm MZ100). 2002 More than 2,500 CEREC users in the United States and over 5,000,000 CEREC restorations placed worldwide. 2003 3D software version is released, allowing users to see 3D views of teeth and models. 2006 CEREC Celebrates 20 Years. 2006 Sirona releases BIOGENERIC version of software. This software allows for the machine to accurately reconstruct the missing tooth shape and surface. 2007 More than 23,000 CEREC users world wide. 2008 Sirona release the MCXL milling unit, this milling unit can produce a crown in 4 mins. 2009 Sirona release CEREC Acquisition Center (AC) powered by Bluecam.
