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.
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. 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.
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 that best resembles the existing tooth color is chosen and placed into the unit. Within minutes, the milling device produces the restoration the dentist designed.
What does a CEREC® restoration procedure involve?
Crowns done in our office are fabricated utilizing Cerec technology. These highly aesthetic, durable crowns have several distinct advantages. They are fabricated in one visit instead of two - therefore there is no need for an impression or a temporary crown. Because there is no second visit, there is also no need to be numb again.
What does an appointment look like to get a one visit Cerec crown?
Color images of the teeth are taken using a special camera. Removal of old fillings and decay is completed, followed by the placement of a bonded build-up as needed. A scan of the prepared tooth is then obtained.
Your new crown is custom designed using the the Cerec software, then milled form a ceramic block. At this point we try-in the crown over the prepared tooth. Margins, contacts with adjacent teeth, and the bite are evaluated. Because of the accuracy of the system adjustments are very seldom necessary.
After polishing a glaze is applied to the crown and it is fired in a computer controlled porcelain oven. The tooth is then isolated and the crown is cemented in place. Home care of brushing and flossing, along with regular hygiene appointments in our office, will help you enjoy your new crown for years to come.
