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. 0000638181 00000 n - Areas of the denture bearing tissue best able to tolerate load and provide support are impressed under increased pressure or functional load.
