To measure the angle between two implants:
Select an implant.
Click Implant angle
on the dedicated Implant tab.
Tip
The measure angles tool can also be accessed via Implant angle
on the Diagnose tab of the Planning toolbar.
The cursor changes into a crosshair.
Select the second implant with the left mouse button.
An arched yellow line connecting the two implants is drawn.

Note
Because two objects are needed for this measurement, the Implant angle button is disabled until an implant is selected.
