The Cerec-3D software was introduced officially at the IDS 2003 with the version 2.00 R1000. The decisive difference compared with the preceding software generations was that the prepared tooth and the restoration were displayed three dimensionally. Thus, the virtual changes which could be made with the aid of editing tools could also be controlled and seen immediately in 3D. The latest officially available version of the Cerec-3D software version 2.10 R1500 differs in some further developments from the first version 2.00 R1000; these are for example: - If the semiautomatic margin detector is switched off while marking the preparation margin, the alternative intensity image appears instead of the 3D display. - Designing has been decisively improved by the extension of the "Drop" tool (function of continuous application and removal of material). - Under morphologically difficult circumstances, the design proposal can be magnified/reduced in size and repositioned in all spatial directions. - The Parameter setting again permits setting an adhesive gap width specific to the dentist and unit. As an example, the version 1500 software is demonstrated on a simple clinical case in which the occlusion points were defined virtually with the aid of a functional bite registration, eliminating the need for occlusal grinding-in.
