Another type of impression technique is selective pressure technique in which stress bearing areas are compressed and stress relief areas are relieved such that both the advantages of muco static and muco compressive techniques are achieved. 0000002246 00000 n Bernard L.

However, the viscoelastic rheological properties of impression materials, particularly the time-dependent viscoelastic changes in impression material immediately after tray seating, are unknown. But all the authors proposed their concepts based on the available information of the underlying functional and histologic anatomy during their time.This article reviews the various ways of achieving selective pressure as seen by different authors and also includes a custom tray design to achieve selective pressure, which is based on the newer concepts of the stress bearing and relieving areas in the maxillary edentulous impression procedures.
