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.
Cerec-3D软件于2003年德国牙科展上正式推出，版本为2.00 R1000。与之前几代软件相比，其决定性差异在于能对预备牙体和修复体进行三维显示。因此，借助编辑工具进行的虚拟更改也能在三维空间中即时得到控制和查看。Cerec-3D软件的最新官方可用版本2.10 R1500在一些方面有进一步改进，与首个版本2.00 R1000有所不同，例如：——在标记预备边缘时若关闭半自动边缘探测器，会出现替代强度图像而非三维显示。——通过扩展“Drop”工具（连续添加和去除材料的功能），设计得到了显著改进。——在形态复杂的情况下，设计方案可在尺寸上放大/缩小，并在所有空间方向上重新定位。——参数设置再次允许设置特定于牙医和单位的粘结间隙宽度。例如，通过一个简单的临床病例展示1500版本软件，在该病例中借助功能性咬合记录虚拟定义咬合点，无需进行咬合磨除。
