CEREC Restoration is a cosmetic dentistry technique which enables a restoration (crown, inlay, onlay or veneers) to be created and fitted in on single visit to the dentist. CEREC combines a number of different computerised technologies, including 3D Photography, Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM).

During the first dental visit an examination would be carried out and the tooth would be prepared under local aesthetic, an impression of the tooth would then be taken, followed by a temporary restoration being fixed onto the tooth; a second appointment would then be arranged for around two weeks later.

The dentist would send the impression and other information to a specialist dental lab for the restoration to be manufactured. At the second appointment the temporary restoration is removed and the permanent restoration placed. With the use of CEREC (CEramic REStoration) technology it is possible for the complete treatment to be carried out within one appointment.

The CEREC Procedure

The area of the mouth where the restoration will be fitted is initially photographed, the photographs are converted into a 3D computerised model and specialised imaging software is used to ascertain the shape of the restoration by a comparison made with the surrounding teeth. The dentist would then refine the computerised design with the use of CAD software.

Following the completion of the design the information will be uploaded to a CAM milling machine, which will then accurately mill the restoration from a solid block of ceramic material with the use of diamond tipped milling tools. This results in an extremely accurately made restoration which will then be bonded to the prepared tooth with resin cement.

This technology was first introduced in its earliest form in 1987 and there are now over 22,000 dental practices which use CEREC worldwide. It is estimated that over 15 million CEREC restorations have been carried out.

Advantages of CEREC

  • Although the dental practice would have to make a considerable initial investment in the CEREC technology and training, in the long term it will work out to be more cost effective than using conventional methods, as the cost of manufacturing the restorations are considerable less than the dental lab fees, and a financial saving will also be made due to only one appointment being needed.
  • Ceramic material is highly suitable for use in dental restorations as it expands, contracts and wears at a similar rate to natural teeth. Furthermore, milled ceramic has considerably more strength than hand layered and pressed ceramic, which is used for conventional treatments.
  • Due to the accuracy of the manufacturing process more of the existing tooth structure can often be preserved with the use of a restoration which partially covers the natural tooth.

One of main principles behind CEREC technology is that it removes the need for guesswork and eliminates the chance of for human error in manufacturing the restoration. This together with the convenience of having a crown, veneer, inlay or onlay fitted in one sitting makes it one of the most important technologies to be used by cosmetic dentists.
