One of the biggest advantages of digital impressioning is to know within seconds if you captured your margins, as opposed to waiting 4 to 5 minutes for the traditional impression to set.  But one common thing between the two is that you must make sure you have soft tissue retraction and displacement of the tissue to discern where the tooth structure ends and the tissue starts.  One big adjunct that accomplishes both those things with relative ease is a soft tissue laser.  Here you see the pre-op condition where you can tell the clinician struggled accomplishing an important task and in the immediate post op, you can appreciate how hemostasis and retraction worked to achieve the desired results

Sweet work! Those are some of the toughest cases.
