The name CEREC stands for Ceramic Reconstruction. This method, which has been in clinical use since 1985, allows for all-ceramic fillings and crowns to be produced in a single sitting. The CEREC system is made up of a recording unit and a milling unit. The recording unit is a mobile PC to which an imaging camera is connected. The tooth needing treatment is scanned without being touched and an image of the tooth appears on the monitor of the recording unit.
The dentist, who has been trained and certified for the use of the CEREC method, must now refine the model of the inlay or crown on the monitor. Next, the lines are converted to milling data and transmitted to the milling unit, where a block of ceramic matching the color and size of the defective tooth is placed. Within 10 to 20 minutes, the milling procedure is completed and the ceramic can be placed in the tooth. Minor adjustments to contact points and bite levels are then made. The entire procedure takes between 60 and 90 minutes.
Advantages for the Patient
Only a single sitting is needed for the patient to receive a highly esthetic, durable and well-tolerated restoration. This makes temporary fillings and crowns as well as bite recordings that last several minutes a thing of the past. Since the restorations produced in the CEREC procedure are made exclusively of ceramic, the metal structures used in traditional procedures are no longer needed. As a result, the patient receives a reconstruction that is entirely free of metal. Scientific studies have shown that reconstructions with the CEREC system are long-lasting. After approximately 13 years, almost 90 percent of the reconstructions remain intact.
Which teeth can be treated with the CEREC procedure?
A treatment using Veneer can be done for almost any tooth requiring a filling, a veneer or a crown. Even gaps can be filled with this method if an implant had been previously used.
