SINGLE VISIT CROWNS, VENEERS, INLAYS and ONLAY
CEREC is an advanced dental restorative system that allows your dentist to restore decayed teeth, place crowns, remove defective amalgam fillings, or place cosmetic veneers in just one appointment. This allows you to have the highest quality, most lifelike dental restorations in just one visit to the dentist…in, out, and on with your busy life.
The CEREC Procedure
CEREC is a method used by thousands of dentists worldwide since 1987 not only to replaceoldsilver fillings, but also to restore any tooth that is decayed, weakened, broken, etc. to its natural strength and beauty. Better yet, it’s done with all-ceramic materials that are tooth colored in a single appointment!
Exam and Preparation
First, your Dentist examines the tooth and determines the appropriate treatment. It could be a simple filling, or a full crown, depending on how much healthy tooth structure is remaining and the clinical judgment of your Dentist. Next, he or she administers an anesthetic and prepares your tooth for the restoration, removing decayed and weakened tooth structure.
Then, your Dentist takes an Optical Impression of the prepared tooth. Instead of filling an oversized tray with impressionmaterial and waiting several minutes for it to harden in your mouth, the dentist lightly coats the tooth with a non-toxic, tasteless powder. A small intraoral camera is then used to take a digital picture of your tooth. This whole Optical Impression process usually takes less than a minute.
Next, the CEREC machine helps the Dentist create the restoration for your tooth. The CEREC 3D software takes the digital picture and converts it into a 3-dimensional virtual model on the computer screen. Your Dentist then uses his or her dental expertise to design the restoration using the CEREC 3D computer software. Within a few minutes, your Dentist clicks a button, and the restoration design data is sent to a separate milling machine in the office. A ceramic block that matches your tooth shade is placed in the milling machine. About 10 minutes later, your all-ceramic, tooth-colored restoration is finished and ready to try in. The dentist tries the restoration in your mouth to ensure proper fit and bite. The restoration is then polished and bonded to the prepared tooth. Your tooth is restored with no “temporary” or return trip necessary. All of this is done in a single appointment! Ask us about CEREC today.

CEREC Acquisition Unit
The CEREC Acquisition Unit is mobile and houses a medical grade computer and the CEREC camera. Your dentist uses the camera to take a digital picture of your prepared tooth. This picture is used instead of a traditional impression. This means no impression tray and material for you to gag on. The computer and CEREC 3D software converts the digital picture to a three dimensional virtual model of your prepped tooth. Your dentist then designs your restoration right on screen using the software while you wait (and watch!). This software can assist your dentist with designing any single tooth restoration: crowns, inlays (fillings), onlays (partial crowns), and veneers. Once your dentist has designed your restoration (usually about 5 minutes), he or she clicks a button, and the design data is communicated via a wireless radio signal to the CEREC Milling Unit.
CEREC Milling Unit
Your dentist or dental assistant selects a ceramic block that matches the shade ofthe tooth being repaired. He or she then inserts the block into the Milling Unit. The data from the Acquisition Unit is used to direct two diamond coated burs to carve the block into the indicated shape of the restoration. This process usually takesabout 10 minutes depending on the size and type of restoration. After the milling is finished, your dentist polishes the finished filling or crown and bonds it into place.
