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.
Optical Impression
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.
Milling Unit
This device is used to 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 time and money.
