What is “CEREC”? CEREC stands for (Chairside Economical Restoration of Esthetic Ceramics), which is the way how modern technology manufacture ceramic restorations.
In old days, dental restorative methods require more than one visit to the dentist. This means that on the first visit, you get an injection of anesthesia, your toothprepared, an impression taken, and a temporary restoration put on your tooth. Your impression sent away to a dental lab to have your restoration make. You make a second appointment for a couple of weeks later, get another injection, have the temporary pried off, and have a permanent restoration put on. The whole procedures sound complicated. Why go to the dentist a second time when you don’t have to? With CEREC technology, our dentists can restore damaged teeth and enhance your smile in a single appointment, making the treatment easy to fit in around a busy lifestyle.
1. A CEREC tooth restoration isn’t just convenient
2. It is also healthy since no metal inside the restoration
3. Strongest restoration in the market, it is made from a dense, compact ceramic block, there is no bubble inside the structure.
4. No metal inside which means it offers better looking, tooth colored ceramic material restore your teeth just like your natural teeth.
5. These materials closely match the composition of natural tooth structure. This means when you eat hot food and then drink something cold, the restoration and tooth expand and contract at almost equal rates. So, your tooth does not crack.
6. The materials are chemically bonded to your tooth, so your dentist can save as much healthy tooth tissue as possible while providing you with a dental restoration that strengthens your tooth. It is a more conservative approach to tooth replacement because it leaves more of the remaining tooth structure intact.
How does the CEREC procedure work?
First, we prepare your tooth for restoration, removing decayed and weakened tooth tissue. Then we take some images of your tooth by 3D intra-oral camera.
After that, the CEREC 3D software processes the digital pictures and converts it into a 3-dimensional virtual model on the computer screen. We then use our expertise to design the restoration using the CEREC 3D computer program.
Within a few minutes, with the click of a button, the restoration design data is sent to a separate milling machine in the office.
A ceramic block is then selected that matches the shade of the tooth being repaired. The block is inserted 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. You can actually see the restoration being milled.
Once the milling is finished, we then polish the crown and put it into the furnace to fire it. The purpose of firing the crown is to sinter the material to make it strong and give a glossy coat.
Approximately 20 minutes later, your all-ceramic tooth restoration is finished and ready to be bonded into place.
