The material and shade for the current restoration can be changed here.
Select the minimum material thickness along the margin. The recommended
margin thickness is 70 to 100 microns to reduce margin chipping or potential
short margins.
Milling Settings only affect proposals with a sharp interior angle, like an
anterior incisal edge. If the interior of the proposal is smaller at the tip than
the tools in the mill, the Standard setting removes extra material at the tip.
This may lead to a crown that is too thin at the top. The options are to round
the preparation or to select Undermill. If Undermill is selected, then the mill
will go as far as the tool's size will allow and the remainder must be removed
manually.
