CEREC 3D CAD/CAM technology
CADCAM (computer aided design, computer aided manufacturing), the technology that produces ceramic restorations and crowns, has revolutionized dentistry over the past few years.
The CEREC (CEramic REConstruction) system, used by many dentists for the fabrication of ceramic restorations, was developed in the 80s and put on the market in 1987. It allows dentists to deliver aesthetic and durable restorations in a single appointment.
Once the tooth is filed down, an optical impression of the tooth is taken with a camera.
The computer program creates a virtual model of the filed down tooth. A restoration adapted to the model is then designed using this same program.
The computer data is sent to a milling chamber, which cuts the final custom-made restoration out of a block of vacuum pressed ceramic.
The restoration or crown is then tried on and adjusted.
A baking process is then carried out to adjust the color and finish of the tooth. This step also allows the restoration or crown to become stronger.
The restoration or crown is cemented to the tooth.
Advantages:
A single visit
The main advantages of this technology are time, the service provided to the patient, and the use of an optimal restoration material.
Time: This method allows dentists to design, fabricate, and cement the restoration in A SINGLE VISIT, by simply taking an optical impression or photo of the tooth. In this way, you won’t need a temporary restoration, nor will you have to wait due to laboratory time frames.
CADCAM technology offers aesthetics, durability, and biocompatibility. According to a number of studies, ceramic gives strength back to the tooth, which allows for increased resistance to breaking compared to teeth restored traditionally with either composite or amalgam.
