The CEREC Procedure
Let’s face it, very few of us have perfect teeth, free of decay, and fillings. You can probably see a filling or two in your own mouth, which do just that — “fill” a cavity, or hole, in your tooth left from the excavation of decayed tooth structure. In many cases, those fillings are made of metal or resin material and can go bad, weaken the tooth, or get additional decay under or around it. In fact, 1.2 billion of these resins or metal fillings will need to be replaced in the next 10 years. CEREC is a CAD-CAM method used by selective dentists not only to replace these 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 for CEREC
First, Dr. Bouzid examines the tooth and determines the appropriate treatment. It could be a filling, an inlay, an onlay, or a full crown, depending on how much healthy tooth structure is remaining and the clinical judgment of Dr. Bouzid. Next, he administers an anesthetic and prepares your tooth for restoration, removing the decay, and weakened tooth tissue. This preparation is just like he would do for many other restorative techniques.
Then, your dentist takes an Optical Impression or scan of the prepared tooth. Instead of filling a tray with impression “goop” that you must bite into and hold in your mouth until it hardens, Dr. Bouzid uses a scan that takes a 3-D digital picture of your tooth. This whole Optical Impression process takes only a minute or two.
Next, the CEREC machine helps Dr. Bouzid 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. He or she then uses his or her dental expertise to design the restoration using the CEREC 3D computer program. Within a few minutes, Dr. Bouzid 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 – 20 minutes later, your all-ceramic, tooth-colored restoration is finished and ready to bond in place. Finally, Dr. Bouzid 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.
What is CEREC? CEREC is an acronym…
- Chairside: The technology is in the dental operatory and used while you are in the chair
- Economical: The procedure is economical for both dentist and patient
- Restorations: The procedure restores your tooth to its natural beauty, function, and strength
- Esthetic: The restorations are metal-free and tooth-colored
- Ceramic: High-strength ceramics are used that are close in composition to your natural tooth structure.
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.
CEREC Acquisition Unit
The CEREC Acquisition Unit is mobile and houses a medical grade computer and the CEREC scan. Your dentist uses the scan 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 convert the digital picture to a three-dimensional virtual model of your prepped tooth. Dr. Bouzid then designs your restoration right on screen using the software while you wait (and watch!). This software can assist with designing any single tooth restoration: crowns, inlays (fillings), onlays (partial crowns), and teeth veneers. Once Dr. Bouzid 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
Dr.Bouzid or his dental assistant selects a ceramic block that matches the shade of the tooth being repaired. The block is then inserted 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 takes 8 to 18 minutes depending on the size and type of restoration. After the milling is finished, the restoration is polished, finished, and bonded into place.
