cerec

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.

  • 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 a method used by thousands of dentists worldwide since 1987 not only to replace metal 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. Trembath 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 Dr. Trembath. 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.

Optical Impression

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 uses a camera to take a digital picture of your tooth. This whole Optical Impression process takes only a minute or two.

No Temporaries

Next, the CEREC machine helps Dr. Trembath 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. Trembath 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, 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.

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 teeth 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 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 filling or crown and bonds it into place.

Uses for CEREC

CEREC Inlay Restoration

Often, patients with amalgam fillings will exhibit amalgam breakdowns and damage to the tooth structure as recurrent decay creates stress fractures on the enamel. Unlike most laboratory-created crowns, CEREC inlay restorations stabilize the integrity of the tooth. CEREC materials ensure maximum bond strength and enhance appearance, resulting in your desired smile. CEREC inlay restorations form a smooth, tooth-colored replacement of dental material lost to cavities. Using ultramodern CAD/CAM technology, CEREC inlays mimic your tooth’s color and structure exactly.


CEREC Onlay Restorations

Silver amalgam restorations regularly result in unsightly crowns and the necessity of replacement over time from recurrent decay. Rather than replace the old amalgam, CEREC onlays are placed on the tooth to retain the original structure and create a more natural look. Onlays, or partial crowns, are more extensive than inlays, and cover the bumps on the tooth surface. The enamel-like material of CEREC mimics the appearance and feel of real teeth.


CEREC Crowns

Patients who lose fillings often need replacement crowns, which can take up to three appointments to fill in. CEREC, however, mirrors the appearance and feel of a normal tooth and only requires one visit to install. Crowns, or tooth-shaped caps placed over teeth, restore the damaged tooth to its original shape, strength, size or appearance. CEREC crowns preserve a healthy tooth structure while restoring your natural smile.


CEREC Veneers

Teeth that have been repaired with compacted composite material often break down, resulting in chipped teeth. CEREC veneers correct the incisal length and angle, restoring the tooth to its original appearance in only one visit. Veneers, or thin laminates of tooth-colored porcelain, are bonded to the front of teeth, covering the front surface and resulting in an improved appearance. The veneers produced by CEREC are custom-designed for each tooth to provide an exact match.


Multiple Restorations

In the past, patients with multiple failed restorations typically required several appointments to achieve a full restoration. With CEREC, however, multiple inlays and onlays can be fabricated, bonded, polished and installed at once. CEREC technology completes the multiple restorations in one visit, resulting in a beautiful smile in a fraction of the time.

Home Care Instructions

Remember that it will take time to adjust to the feel of your new bite. When the bite is altered or the position of the teeth is changed it takes several days for the brain to recognize the new position of your teeth or their thickness as normal. If you continue to detect any high spots or problems with your bite, call our office at (303) 457-3046 so we can schedule an adjustment appointment.

It is normal to experience some hot and cold sensitivity. The teeth require some time to heal after removal of tooth structure and will be sensitive in the interim. Your gums may also be sore for a few days. Warm salt water rinses (a teaspoon of salt in a cup of warm water) three times a day will reduce pain and swelling. A mild pain medication (one tablet of Tylenol or Ibuprofen (Motrin) every 3-4 hours) should ease any residual discomfort.

Don’t be concerned if your speech is affected for the first few days. You’ll quickly adapt and be speaking normally. You may notice increased salivation. This is because your brain is responding to the new size and shape of your teeth. This should subside to normal in about a week.

Daily brushing and flossing are a must for your new dental work. Daily plaque removal is critical for the long-term success of your new teeth, as are regular cleaning appointments.

Any food that can crack, chip or damage a natural tooth can do the same to your new teeth. Avoid hard foods and substances (such as beer nuts, peanut brittle, ice, fingernails, or pencils) and sticky candies. Smoking will stain your new teeth. Minimize or avoid foods that stain such as coffee, red wine, tea and berries.

If you engage in sports let us know so we can make a custom mouthguard. If you grind your teeth at night, wear the night guard we have provided for you. Adjusting to the look and feel of your new smile will take time. If you have any problems or concerns, please let us know. We always welcome your questions.
