Cerec Restoration Technology
What is CEREC?
Cerec stands for: Chairside Economical Restorations of Esthetic Ceramic or CEREC for short is a new state-of-the-art method of reconstructing tooth restorations. CEREC uses computer-assisted design (CAD) and computer-aided manufacturing (CAM) to offer single-day crowns, veneers and bridges. This new technology has changed ceramic restorations such as crowns and veneers so that there is no longer a wait between the preparation and final product. With CEREC, the technology is used while sitting in the dental chair. The restorations created are metal-free and tooth colored to restore the tooth’s natural beauty, strength and function. With CEREC’s CAD-CAM technology, these ceramic restorations can usually be done in a single dental visit.
The CEREC® Process
CEREC® uses CAD-CAM technology to design and fabricate custom restorations during one dental visit. So how does this process work?
Exam and Preparation
To begin with, the dentist will determine if CEREC is the right option. The amount of healthy tooth remaining will determine the course of action. After reviewing options, the dentist will begin the process by giving anesthetic and prepping the tooth for the crown or veneer by removing decay and weakened tooth tissue.
In order to make the dental crown, 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 crown without the need to take a messy impression. This means, no bad tasting impression material. The computer and CEREC 3D software then converts the digital image into a three-dimensional virtual model of the tooth.
The Milling Unit is used to used to create the crown designed for the tooth. Based on the original tooth color, the dentist is able to select the correct colored ceramic block. The milling unit will then create the dental crown.
Placing the Crown
After the crown is made, it is ready to be tried on to ensure a proper fit and bite. When it is ready, it is polished and bonded into place by the dentist. Therefore, no temporary crown is needed and no return trip is necessary. Additionally, Cerec is a great compliment to the already extensive list of Cosmetic Dentistry procedures including composites.
Advantages to Using CEREC
CEREC has changed the dental crown process. It was created with the patient in mind in order to make a dental visit as simple as possible. Some of the benefits to using CEREC are:
- Most procedures can be done in one visit – less costly and less time-consuming
- Less painful injections due to single-visit
- No need to take messy impressions
- No need to have a temporary restoration for in-between visits
- Ability to save as much natural tooth structure as possible
- Longer lasting restorations – may last over 10 years
- Restores teeth to natural beauty, function and strength
- Metal-free restorations
