Depends on the settings used on the machine (personal preference), depends
on the accuracy of the powder layer, depends on the consistency of optical
impression line of draw, and how much the operator trusts the machine to
tell him where the occlusion is. If you trust the machine, are consistent
with powdering and imaging, and set the machine parameters properly, you can
drop them in with out touching the occlusion. I personally am a bit OCD, so
I will often leave a bit extra on the occlusal surface so I can refine it
myself. Also, the operator always has to trim back any adhesive flash,
which might look like the occlusal surface is being adjusted. If you do
nothing to establish occlusion during the design, they are as tough to
adjust the occlusion on as when you make an amalgam core and you work the
occlusion into perfection. In these cases, 30-60 seconds with a football
shaped diamond is enough time to create 4-5 well contoured triangular ridges
with some tertiary anatomy as well.

need to adjust the surface after a crown was placed.
