“…[14][15][16][17][18] When connecting the ball matrix to the implant with autopolymerizing resin, the patient was asked to keep the dentures in centric occlusion using moderate pressure, so that the denture base was in intimate contact to the supporting tissues. 35 However, there was no freeway between the matrix and the ball itself. So, when patients used higher pressure during chewing and/or loaded the denture unilaterally the ball functioned as centre of rotation which might explain the relatively high incidence of fractures to one part.…”

“…Techniques for making impressions of edentulous ridges are classified as non-pressure, pressure, and selective pressure impressions (8)(9)(10)(11)(12)(13)(14). Non-pressure impression is a technique for making an impression of the stationary state of ridges while minimizing impression pressure.…”

“…Pressure is adjusted by varying spacer thickness and the number and size of escape holes. Hyde et al reported that dentures prepared using selective pressure technique were preferable to those prepared with conventional techniques (12). Some evidence suggests that the selective pressure technique is the best method for making impressions of edentulous ridges (9).…”

The aim of this study was to examine the effects of tray design and impression material on impression pressure in a clinical simulation model of an edentulous mandible. Two types of polyvinylsiloxane elastomer, one type of polyether elastomer, and one type of alginate were used. The three tray types had no relief, 0.36 mm of relief, or 1.4 mm of relief, with or without escape holes. Impression pressure was measured at the median alveolar crest, the bilateral alveolar crests corresponding to molars, and the bilateral buccal shelves. Impression pressure significantly differed in relation to tray design and sensor position. In trays without escape holes, impression pressure was highest at the median alveolar crest and lowest at the buccal shelves, for all impression materials. However, impression material had no significant effects on impression pressure. Our results suggest that bite-pressure load on alveolar crests can be alleviated by making an impression with a tray that has relief and escape holes, while applying pressure to buccal shelves and almost no pressure to alveolar crests.

“…This advocates the selective pressure impression technique and provides dentists with good evidence for the clinical procedure. 11 According to Taylor and colleagues, selective-pressure impression technique described provides the clinician with a method for improving the palatal adaptation of maxillary complete dentures. By displacing the tissues of the palate and effectively creating a deeper vault on the definitive cast, the technique compensates for the shrinkage of the polymethylmethacrylate.…”

Impression is basically an interaction between tissues and impression material. The variety of impression materials and the range of working characteristics of these materials, make possible the development of impression procedures best suited for specific conditions. Our method for making impressions should be based on the basic principles of maximum area coverage and intimate contact so as to achieve the objectives of retention, support, stability, esthetics, preservation of ridge (supporting structures). Various impression techniques have been mentioned in the literature for recording impression of edentulous ridges. These techniques have been classified by different authors as functional, mucostatic, mucocompressive, selective pressure, minimal pressure etc. However none of these techniques has been designated as the 'time best' for a particular patient though selective pressure technique has got much attention in the literature. This article is presenting a critical review on the selective pressure impression technique used for edentulous patients.
