9 Setting up restoration
If you select IPS e.max ZirCAD for crown material, you also need to
select the preparation type, either Chamfer Edge or Shoulder Edge
(default):
As instructed in the pop-up, a Chamfered restoration may require
manual polish on the milled margin (pre-firing) to prevent overhanging to
the margin.
Select OK to proceed or Cancel to change your selection. For how this
material selection affects the milling unit screen see section "Milling IPS
e.max ZirCAD" in chapter "Sending restoration to milling unit" on page
159 and the Planmeca PlanMill 30/40 S manual for information on how
this material selection affects milling.
6. Select translucency (if applicable for the selected material). You can
choose from low (LT), medium (MT) or high (HT) translucency.
