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 material and can go bad, weaken the tooth, or get additional decay under or around it. In fact, 1.2 billion of these metal fillings will need to be replaced in the next 10 years. CEREC® is a method used by thousands of dentists worldwide since 1987 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 & Preparation
First, Dr. Annapolen 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 him. Next, Dr. Annapolen administers an anesthetic and prepares your tooth for the restoration, removing decayed and weakened tooth tissue. This preparation is just like he or she would do for many other restorative techniques.
Then, he takes an optical impression 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. Annapolen coats the tooth with a non-toxic, tasteless powder. A camera is then used to take a digital picture of your tooth. This whole optical impression process takes only a minute or two.
Next, the CEREC® machine helps 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. Dr. Annapolen then uses his dental expertise to design the restoration using the CEREC® 3D computer program. Within a few minutes, he 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. Annapolen 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 for …
- 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 Dr. Annapolen 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 office … 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 camera.Dr. Annapolen 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. He then designs your restoration right on screen using the software while you wait (and watch!). This software can assist him with designing any single tooth restoration: crowns, inlays (fillings), onlays (partial crowns), and veneers. Once Dr. Annapolen has designed your restoration (usually about 5 minutes), he clicks a button and the design data is communicated via a wireless radio signal to the CEREC® Milling Unit.
CEREC Milling Unit
Dr. Annapolen selects a ceramic block that matches the shade of the tooth being repaired. He 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 takes 8 to 18 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.
