Thank you for this clear lec Dr. About the final impression, is it possible to take it with with silicone light body material? And do we make perforations in the special tray?
Ok so you take your impressions fix all the undercut and blemishes. Develope acrylic base add the spacer then take another impressions the model will have the original undercut in it. I don't see the point. Maybe more refined but the you have to redo the undercuts.
