Chairside Economical Restorations of Esthetic Ceramic (CEREC©) has revolutionized dental procedures. Traditionally, if crowns, onlays, inlays or dental veneers were required to restore damaged teeth, multiple procedures and a great deal of waiting time in-between would be inevitable. CEREC© creates these ceramic restorations within minutes in the dental office. This means that many treatments can be completed in just a single visit.
CEREC© is comprised of several computer-assisted design (CAD) tools and a milling machine that creates custom ceramic restorative devices. CEREC© can benefit almost anyone needing a ceramic restoration. This is of great benefit to nervous patients, and it can also reduce the cost of treatment.
CEREC© can benefit almost anyone needing a ceramic restoration. Exceptions include patients who have a prior history of breaking ceramic devices and those with a deep bite. CEREC© devices are proven to last for over 5 years, but recent research indicates that most CEREC©-created restorations last for more than 10 years.
The CEREC© System is sometimes called a CAD-CAM system. CAD-CAM means Computer Assisted Design and Computer Assisted
The first step in the procedure is to prepare the tooth. The dentist removes all tooth decay and creates a divergent occlusal axial wall, to make the opening of the tooth wider than the base. Next, an impression is made using a covering of titanium dust. This dust allows the camera to take a highly detailed picture of the tooth. Images are formulated with the CEREC© camera. CEREC© optical imaging utilizes an infrared wavelength.
The image is transposed onto the computer screen. It is here that the dentist is able to view the tooth from every angle and design the final restoration. When the design is complete, it is transmitted to the milling unit. The dentist chooses a block of ceramic that matches the color of the teeth. This ensures that the restoration will be almost invisible.
Within 15 minutes, the full crown, onlay, overlay, or veneer is complete. The restoration is made of compressed, rather than laboratory-layered, porcelain. This enhances strength and durability.
Before affixing the restoration to the tooth, the dentist will place it dry to ensure it fits perfectly. It is then polished and affixed to the tooth with dental cement. The procedure is now complete and all without the need for a second visit! The quality of the results is the same as the laboratory-generated restoration, but a great deal of time and money has been saved.
