CEREC Single visit dentistry is here!
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, two visits and three weeks of waiting time in-between would be inevitable. CEREC® creates these ceramic restorations in the dental office. This means that many treatments can be completed in just a single visit. No more silver fillings. These ceramic, tooth colored restorations will last a long time.
CEREC® is comprised of several computer-assisted design (CAD) tools and a milling machine that creates custom ceramic restorations. CEREC® can make almost any ceramic restoration to order, meaning the dentist can place it immediately
How can CEREC® benefit me?
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. Recent research indicates that most CEREC®-created restorations last for more than 10-15 years.
Here are some other advantages associated with CEREC®:
No temporary restorations.
High-quality ceramic products.
Less injections and discomfort.
Fewer dental visits.
More natural tooth is saved.
Long lasting restorations.
What is the CEREC® system comprised of?
The CEREC® System is sometimes called a CAD-CAM system. CAD-CAM means Computer Assisted Design and Computer Assisted Milling. The CEREC® system has three major components:
Acquisition device: This device is home to a high-quality camera and a medical grade computer. The function of this unit is to photograph the prepared tooth. Three-dimensional images are created of the tooth on the screen, which the dentist uses to design the perfect ceramic restoration.
Three-dimensional CAD software: This software allows the dentist to examine the tooth from every angle. It is the closest possible thing to holding the tooth in the hands and rotating it.
Milling device: This unit actually manufactures the custom restoration from the specifications entered into the computer. A ceramic block, which best resembles the existing tooth color is chosen and placed into the unit. Within minutes, the milling device produces the restoration the dentist designed. No horrible-tasting impressions or time-consuming transfers to and from the laboratory are required.
What does a CEREC® restoration procedure involve?
The first step in the procedure is to prepare the tooth. 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 12 minutes, the full crown, onlay, inlay 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.
If you have questions or concerns about CEREC®, please ask your dentist.
