The technique I use takes about two and one-half minutes for upper and lower arches and it does not gag the sensitive patient. For two years now, we have taken Onmicam impressions for study model and appliance impressions in the Klim office.  This video will clearly document the isolation approach and Omnican scanning flow to gain a predictable impression result.  And by the way, using the technique proposed in this video provides a predictable upper and lower arch mount with just the buccal scan quadrant from one side.  This approach is so much more effective than using the Ortho Software, at least at this point in time.
