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 time, those fillings can go bad, weaken the tooth, or get additional decay under or around it. In fact, 1.2 billion of these 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 replacedefective fillings, but also to restore any tooth that is decayed, weakened, broken, etc. to its natural strength and beauty. In many cases, CEREC onlays and inlays can be used to restore teeth that would have been restored withfull coverage crowns in the past. CEREC technology has improved the practice of dentisty by enabling dentists toconserve tooth structure, that would have been removedin the past. Better yet, it’s done with all-ceramic materials that are tooth-colored in a single appointment. This means no temporaries!
Exam and Preparation
First, your Dentist examines the tooth and determines the appropriate treatment. It could be a porcelain inlay, partial crown(onlay) 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 tissue. This preparation is just like he or she would do for many other restorative techniques.
Then, your Dentist 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, your Dentist 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 few minutes.
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 program. 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 higly compressed 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, your 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.
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, or remove defective amalgam fillings 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 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 gooey material. 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 crowns. Once your dentist has designed your restoration, 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 of the 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 takes 8 to 18 minutes depending on the size and type of restoration. After the milling is finished, your dentist polishes the finished inlay, onlay or crown and bonds it into place.

Dr. Pryzgoda chooses carefully which and when radiographs are taken. There are many guidelines that we follow. Radiographs allow us to see everything we cannot see with our own eyes. Radiographs enable us to detect cavities in between your teeth, determine bone level, and analyze the health of your bone. We can also examine the roots and nerves of teeth, diagnose lesions such as cysts or tumors, as well as assess damage when trauma occurs.
Digital imaging allows us to store patient images, and enables us to quickly and easily transfer them to specialists or insurance companies.
