Commonly Asked Questions About CEREC (Ceramic Reconstruction)
How long has CEREC technology been around?
CEREC is a brand name – the technology is called CAD/CAM (Computer-aided design and computer–aided manufacturing). CAD/CAM dentistry has been in use since the mid-1980’s. Early efforts were considered a cumbersome novelty, requiring an inordinate amount of time to produce a viable product. This inefficiency prevented its use within dental offices and limited it to lab-side use (that is, use within dental laboratories). As adjunctive techniques, software, and materials improved, the chairside use of CAD/CAM (use within dental offices) increased.
Will I get a good colour match to my other teeth with these crowns?
We have a wide shade selection of tooth-coloured ceramic blocks to restore your teeth to their natural function, strength and beauty and closely matches the composition of your natural tooth structure. To further enhance the aesthetics we are able to customize the colour of your new crown for a natural look to blend it beautifully with your natural teeth.
How is the crown made?
Once Dr. Provo have finished the preparation of your tooth they will take an optical image of the prep site with a special 3D scanner. The scanned information is then turned into a 3D model on the computer. While you watch, Dr. Provo will design your new crown according to your tooth’s appropriate form and function. When they have completed the design your precise specifications are sent via Bluetooth to the milling chamber where diamond burs carve your restoration out of a solid block of ceramic.
How long does the milling process take?
The milling process takes approximately 10-25 minutes depending on what type of ceramic block is selected. Once the milling has been completed your crown will be placed into the firing oven to harden and strengthen the crown for durability. The total time in the oven is 15-30 minutes depending on the ceramic block.
How strong are these crowns?
A CEREC crown will be about as strong as your natural teeth. For people who are clenchers /grinders typically a Zirconia block will be selected for its higher megapascal strength. (You can hit it with a hammer and it will not break!!) Milled ceramic is stronger than the traditional method of layering and pressing, porcelain, so your smile will stay beautiful for years!
What types of restorations can be made with CEREC technology?
Any single or multiple tooth restorations in the mouth such as, veneers, inlays, onlays, crowns placed on either natural teeth or on implants and bridges that were previously processed by a dental lab can be made utilizing the CEREC technology.
Will my dental benefits contribute toward CEREC Crowns?
Yes, should you have dental benefits that include major coverage, your benefit plan will contribute towards your crown. Prior to your appointment, our treatment concierge will submit a predetermination to your benefit plan to confirm eligibility and the contribution amount. The contribution from your benefits is based on the terms of your plan contract that was negotiated between your employer and benefit carrier.
