What is CEREC?
CEREC (Chairside Economical Restoration of Esthetic Ceramics, or CEramic REConstruction) is a method of CAD/CAM dentistry developed at University of Zurich in 1980 for creating dental restorations like crowns, veneers, inlays, onlays, bridges, abutments and crowns for implants. With the aid of CAD/ CAM technology (computer-aided design and computer-aided manufacturing), we can now design, fabricate and insert ceramic restorations in your mouth in just one appointment, rather than waiting for 1-2 weeks for them to get fabricated in a dental laboratory.
CAD/CAM system has been on the market for over 30 years and over 250 scientific studies have confirmed the clinical safety of CEREC tooth restorations. Worldwide, more than 30 million tooth restorations have been produced with CEREC. Our office is proud to offer this amazing treatment to all of our patients.
At Lakeview Dental Centre we use different types of dental ceramics to fabricate your CEREC restoration based on your individual need. Dental ceramic is not only a highly esthetic choice to repair or replace your teeth, but could offer unparalleled strength, resistance to stains and biocompatibility, meaning that is very well tolerated by your body.
Inlays and onlays are ceramic restorations designed to replace an old silver filing or a broken , part of your tooth.
A dental veneer is a thin layer of ceramic placed over the front part of a tooth to improve the esthetics of a tooth:colour and/or shape.
A crown, or 'cap', is a hollow, artificial tooth surrounding your own tooth to protect it. If your tooth is damaged but not lost, a crown can be used to restore its shape, appearance and function. We would recommend a crown if you have a root canal, a large filling in a tooth or a broken tooth. They can also be used to change the shape or colour of a tooth. Ceramic crowns look and function exactly like a natural tooth. Implants can have ceramic abutments and they always get covered with crowns.
Bridges are generally used to replace one or more missing teeth, they “bridge the gap” that missing teeth create in your smile. To accomplish this, crowns are placed over the natural teeth on either side of your gap to help anchor a false tooth into the open space.
How are CEREC restorations made?
First, Dr. Newman removes any old filling(s) and existing decay and prepares the tooth for the restoration. A blue powder is applied on the teeth and images of the prepared tooth along with opposing teeth and the bite are recorded directly into the CEREC computer. A three dimensional model of your teeth appears immediately on the computer monitor and you can watch the CEREC screen as Dr. Newman manipulates the 3D software where the missing part of the tooth prepared is designed to fit back in place, like the piece of a jigsaw puzzle. The result is a digitally customized and very exact replacement for your tooth.
The digital information is then sent to a robotic milling machine for processing. A ceramic block that matches the exact colour of your own natural tooth is selected and placed in the milling unit, where a precise diamond-cut ceramic restoration is instantly created, just for you.The new custom-made restoration is bonded onto your tooth and any necessary adjustments are made for your comfort. Some stronger ceramics, after being adjusted into your mouth require to be place into a special furnace where the final restoration will gain extra strength (3X stronger than the enamel of your natural tooth!) and only after that they will get bonded onto your tooth. This process takes about 30 min.
Within minutes your CEREC restoration is complete. One of the best things for you is that the whole CEREC process avoids the use of messy impressions, wearing a temporary restoration for 1-2 weeks that could jeopardize the vitality of your tooth due to bacterial leakage or having to return to be re-frozen to insert the permanent restoration. Instead, the restoration is milled by the 3D machine in about 9-15 minutes and bonded into place that day.
How long do crowns and bridges last?
This often depends on the type of crown or bridge as well as how you care for your restoration after treatment is complete. However, restorations can last between five and fifteen years. Most dentists will expect them to last about ten years, but your level of care and hygiene can affect their lifespan.
How to care for your crown or bridge?
Proper dental hygiene at home is very important for keeping your restorations strong and healthy. Their longevity depends largely on the health of surrounding tissues so be sure to brush and floss regularly to prevent gum disease and/or tooth decay. Out team at Lakeview Dental Centre can explain the proper way to brush and floss your teeth; you can also read more about dental hygiene here... Scheduling regular dental cleaning appointments will also help maintain your crowns or bridges. Because it is easier to fix a problem when it’s in its early days, be sure to come in for a check-up every six months. Your dentist and hygienist will be thoroughly examining any possible signs of problems.
