What is CAD/CAM system?

The CAD-CAM system means the design of a prosthetic structure on a computer (Computer Aided Design) followed by its production by a machine (Computer Aided Manufacturing).

The main objectives of this technology are automating a manual process in order to obtain high quality material, standardize manufacturing processes and reduce production costs.

One of the main advantages of this technique is the large decrease in reliance on manual execution crowns, veneers, bridges and at the same time decreasing the cost.

The first system to be used and marketed viably was the CEREC (Ceramic Reconstruction) developed by Morman and Brandestini in 1980 at the University of Zurich, Switzerland. During the last 20 years, there has been a large development of the CAD-CAM technology with regard to the reading of dental preparations (optical, contact, laser scanning), the virtual design programs, materials (such as, for example, alumina, zirconia and titanium) and machining of prosthetic restorations.

 

CEREC ®

What is the CEREC?

It´s a technology built in Germany which consists of a sophisticated computerized treatment system. Capabilities using CAD / CAM allows building ceramic crowns without metal. And the only equipment in the world that allows the dentist to design and build crowns perfectly adapted in just a query.

This extraordinary technology allows save more substance dental comparing to conventional crowns.

 

How the CEREC works?

An optical non-contact with the tooth preparation is performed. The generated 3D image is then transferred to a computer system in which the CAD program allows for the design of the structure. The finishing line is detected automatically, and can also be adjusted manually, and is then performed in the milling machine of the same system (CAM).

The system allows production of hoods, inlays, partial crowns, veneers, and crowns, in a single session.

 

Which are the advantages?

Advantages:

- Speed ​​and Convenience-in a day or two has its crown ready, rather than waiting a week or two;

- Biocompatible-minimal irritation of the gums;

- Minimum tooth wear-Conserves natural tooth structure, so there is less loss of tooth substance;

- Resistance to fracture;

- Simulation of the natural enamel;

- No need temporary crowns.
