What are some clinical tips for revealing the margins in digital scanning?
Remove deep inflamed tissue with a diode laser (Odyssey Navigator, Ivoclar Vivadent). Retract moderately inflamed tissue with cord and hemostatic agent. Place the cord and let it sit for 5-10 min. Remove just before scanning. A paste retraction material (Expasyl, Kerr Corporation) is a good option in areas of slight inflammation. CAD systems cannot create a margin that you do not reveal.
