CEREC (Chairside Economical Restoration of Esthetic Ceramics) is an advanced dental restorative system used by modern-day dentists to repair decayed teeth, remove faulty amalgam fillings or place crowns and cosmetic veneers in just a single appointment. Developed in Switzerland in 1985, it is the only chair-side dental CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) restoration system in the world to date.
CAD/CAM technology has found its way into the field of dentistry via CEREC. The process enables dentists to produce different forms of ceramic dental restorations and orthodontic appliances consisting of crowns, veneers, fixed bridges inlays and onlays, as well as dental implant restorations for patients in a same-day visit.
The CEREC® Procedure
The dentist will first examine your tooth to determine a suitable treatment. Depending on how much healthy tooth structure is present, the dentist decides whether you need a simple filling or a full crown. He will then administer anesthetic and remove decay and weakened tooth tissue to prepare your teeth for the restoration. This preparation phase is similar to that of most traditional dental restoration techniques.
Unlike conventional restorations however, the dentist won’t need to take impressions of your teeth using traditional molds that are sent to a dental lab. Instead, all he needs to do is coat the tooth with a thin layer of blue anti-reflective contrast medium (usually in tasteless, non-toxic powder form), take an optical impression using the CEREC® 3D software and camera and upload the images to the CEREC® computer. The whole process will only take a minute or two!
A restoration can then be designed using the 3-dimensional virtual model of your tooth that has been stored in the computer. Restoration design data is sent to a milling machine that creates the restoration from a ceramic block that matches the color of your teeth. Depending on the complexity of the restoration, milling time varies from 5 to 20 minutes after which your all-ceramic restoration is done and ready to be bonded.
Before fixing the restoration onto the prepared tooth, your dentist will test it out to ensure a proper fit and bite. If all seems fine, the restoration is polished and permanently bonded. No temporaries are needed and you get all these done in a single visit to your dentist!
