Creating the framework from the anatomic shape (Shrinking/Cutback)
|You may exclude certain parts from the shrinking, which will then be kept in full anatomic shape. This is useful e.g. for creating lingual bands, or for designing a metal chewing surface if you don't have enough space for ceramic on the occlusal side. Check  – observe how the teeth then turn yellow; they are now responsive to mouse actions. Drag and drop the mouse on the teeth to mark areas that will be excluded from the shrinking.
Slider  controls the thickness of the brush used for marking. Double click on the slider. This puts a collar on all the crowns of the restoration. To provide all crowns with only a lingual collar double click on the slider and simultaneously keep the “Ctrl” key pressed.
In some cases, it may be beneficial to have less reduction on the lingual side. You can achieve this result by setting slider  to a value below 100%. E.g. if you have set a depth of 1mm , and set  to 60%, then the shrinking will be just 0.6mm on the lingual side. By default, this lowered value is only applied to anterior teeth; to apply it to all teeth, uncheck .
Click „Apply“  to perform the shrinking without switching to the next wizard screen, or click „Next“ to shrink and move on.
If the checkbox “Cut back reduced mould again”  in the Expander Multi-level cut-back is activated, areas already cut back can be marked anew and then cut back.
