Dental crowns are effective way to improve the appearance of your smile and strengthen week teeth and prevent any further damage or decay. Crown, sometimes called “cap”, is porcelain, plastic or metal covers placed over the tooth. Crowns repair teeth that cannot be restored with fillings or veneers because there is no enough tooth structure left. When complete, the tooth is stronger and looks and feels natural.What is CEREC®?
CEREC® is a state-of-the-art technology that allows us to quickly restore damaged tooth in just one office visit using ceramic material that matches the natural color of other teeth. CEREC® uses optical impression and computer to fabricate the crown. That essentially eliminates the possibility of human error and makes the fit of the crown more precise. How does the new technology work?
The process starts with the dentist using a special camera that captures three-dimensional image of the tooth and adjacent teeth. Then special software is used to create design for the crown. A mouse click sends the design to the milling machine, which sculpts the tooth from a small block of very strong ceramic. Finally the dentist bonds the new restoration to the tooth. All is done in one single visit.
Why choose CEREC?
CEREC® has revolutionized the restorative process. It was created with the patient in mind in order to make a visit to the dentist as pain-free as possible. Some of the benefits to using CEREC® are:
- Ability to save as much natural tooth structure as possible by fabricating partial crowns, inlays, onlays
- One visit, one time injection placement
- Longer lasting: precise fit increases longevity
- No messy impressions
- No temporary crowns to wear while waiting for the permanent
- Metal-free, tooth colored biocompatible ceramic material
- Natural look and feel
The CEREC® Process
CEREC® uses CAD-CAM technology to design and mill custom restorations during one visit to the dentist. So how does this process work?
Exam and Preparation
Before you get started, your dentist will determine if CEREC® is right for you. Depending on how much healthy tooth structure you have remaining, it may be a simple filling or you may need a crown. After reviewing your options, the dentist will begin the process by administering anesthetic and preparing your tooth for restoration by removing decay and weakened tooth tissue.
In order to make the desired restoration, a 3-dimensional image of the tooth that needs to be restored must be created from a digital camera scan of the tooth. This three-dimensional image will be used to create the restoration without the need to take a messy impression. This means no horrible tasting impression material for you to gag on. The computer and CEREC® 3D software then converts the digital image into a three-dimensional virtual model of the prepared tooth.
This device is used to create the custom restoration needed for the tooth. Based on the original color of your tooth, the dentist is able to select the correct colored ceramic block and in a few minutes, the milling device is able to create the restoration needed.
Placing the Restoration
After the restoration is made, it is ready to be tried on to ensure that you get proper fit and bite. When it is ready, the restoration is polished and bonded into place by your dentist. Therefore, no temporary restoration is needed and no return trip is necessary, saving you
