The objective is a shared retention and force distribution between implants and soft tissues, while ensuring necessary support from denture bases. A two-stage impression technique is proposed to eliminate much of the need for finished denture base modification. Learn about using various impression techniques using PVS materials and trays to make impressions for LOCATOR overdenture cases! Affiliations. In fabrication of complete dentures and overdentures, impressions show hard and soft structures of the denture-bearing area, their biological and physical properties and the relationship between displaceable and non-displaceable mucosa for the purpose of achieving the best possible valve effect. It is possible to fabricate a titanium bar entirely by a digital process, i.e. In addition, these images may also serve as a reference point for monitoring future marginal bone levels. INDIRECT (CLOSED-TRAY) TRANSFER TECHNIQUE 82. Although there are references in the literature regarding the lack of scientific evidence for the importance of functional impressions for the success of complete denture and overdenture treatment (36, 37), this paper argues that standardization of their procedures and use of proven techniques and materials ensures good retention and stability of complete dentures and overdentures.
