Cercon single units and frameworks are fabricated using a CAM (computer aided manufacturer) process. The restoration is first designed in wax on a conventional working model. The waxed restoration is sprued into specialized holding blocks and placed in the Cercon Brain for scanning where a confocal, class II laser takes precise measurements of the pattern. The data is then enlarged by the Cercon Brain to allow for shrinkage that will take place during the final sintering. A zirconia block is then milled to replicate the expanded pattern and is placed in a specialized sintering furnace where final sintering takes place.
