Leveling occlusion for NobelBiocare

Any ideas how to level the occlusion in a first scan in NobelBiocare? The patient wears a guide and an occlusal splint that locks in the opposing teeth, which closes and locks the biting plane. The iCAT lines the patient up on one side, but I am getting slightly lopsided scans from the patient, and have to readjust and rescan.

I wish I knew - Nobel BioCare is really popular here and I have the same concerns. I also have a question: how do you position the patient so that most of the field of interest of the axial slices thru the guide avoids passing thru the metal restorations?

You don't need to re-scan. You can adjust the patient to the proper position in the MPR views and when you export to DICOM, the adjustments are saved. You have to export using an "Action" (I'm at my home computer and can't recall exactly if "Action" is the right term). Anyway, there is a right way and a wrong way to export to DICOM and I'll try to post the "right" way when I get into work on Friday (if I remember). Also, when I adjust the patient orientation, it helps to thicken the slice on the Sagital and Coronal views and then view as MIP. It looks like a skull and it's easier to make adjustments.
