Complete denture secondary impression technique to minimize distortion of ridge and border tissues

A retrospective comparison of two definitive impression techniques and their associated postinsertion adjustments in complete denture prosthodontics

“…The techniques for definitive denture impressions can be classified as mucostatic, 12 maximum displacement, 13 functional, 14 or selective pressure 15 . Variations in these fundamental concepts have been described by numerous authors 3,11,15,16 . It has been acknowledged that a single technique cannot be used for all clinical situations 3,4 .…”

“…10 The definitive impression technique is reportedly one of the more critical elements in complete denture prosthodontics. 11 The objective in definitive impressions is for clinicians to obtain accurate impressions of the denture-bearing areas of the edentulous jaws. 9 Accurate impressions are important in fabricating stable and retentive prostheses with optimal esthetics and function and a comfortable fit for edentulous patients.…”

“…15 Variations in these fundamental concepts have been described by numerous authors. 3,11,15,16 It has been acknowledged that a single technique cannot be used for all clinical situations. 3,4 Textbooks in com-plete denture prosthodontics describe numerous theories and techniques for making definitive denture impressions.…”

Determination of the lingual border of lower complete dentures: How to use a silicone impression material?

“…The border for complete dentures plays a significant role in the stability, retention and bracing of the denture base during normal functions . To date, a conventional modelling compound has been used in the border‐moulding process, although applying it requires training and experience as well as the application of segmental procedures because of its thermoplasticity.…”

Rheological properties of elastomeric impression materials for selective pressure impression technique

“…To achieve this, tray design [10][11][12][13], seating velocity of the impression tray [12,14], and viscoelasticity of impression materials must be considered [15][16][17][18][19][20]. With regard to tray design, Komiyama et al [13] noted that when making an impression of an edentulous maxillary arch using the selective pressure technique, optimal pressure can be obtained using a tray with escape holes of 1.0 mm or larger, or a 1.40-mm-thick wax base plate as a spacer.…”
