[Original technique for secondary impressions in complete removable dentures (CRD)].

Abstract

Regardless of its anatomic shape, an edentulous arch is formed by two types of mucosa, different in both nature and behavior. This is why the impression of such a complex requires two distinct steps with two different modeling materials with different consistency. The first step is the border molding of the mucosal reflexion zone with a silicone of medium viscosity, placed on the borders of the custom tray. The second step is the static impression of the inner part of the denture, with a fluid or very fluid silicone.
