selective pressure impression technique material

J Am Dent Assoc 1967;75:1145-66. The choice of impression material may also be affected by the technique to be adopted, with a major consideration being the selection of a stock tray or special tray. NIH Newer elastomeric materials for Trajectories of jaws. The selective pressure technique is a combination of extension for maximum coverage within tissue tolerance with light pressure or intimate contact with the movable, loosely attached tissues in the vestibules. The selective pressure technique makes it possible to confine the forces acting on the denture to the stress-bearing areas. 1996 May;75(5):512-4. doi: 10.1016/s0022-3913(96)90455-2. Theories of impression making have evolved trough trial of a variety of materials and techniques. A review of residual ridge resorption and bone density. Charles C Thomas Publication: 1957. USA.gov. COVID-19 is an emerging, rapidly evolving situation. Complete denture impressions. Clipboard, Search History, and several other advanced features are temporarily unavailable. In the selective impression technique, the impression material is removed when the application of impression pressure is desired, while relief and/or escape holes are installed in the tray to reduce the pressure when the application of impression pressure is not desired. Would you like email updates of new search results? Three different impression tech-niques are used for selective pressure impressions. Selective pressure impression (SPIT) technique is based on the premise that the stress bearing capability of the denture bearing area must be taken into account while recording the impression. However, the viscoelastic rheological properties of impression materials, particularly the time-dependent viscoelastic changes in impression material immediately after tray 12 Lammie.

Make a nasal impression with irreversible hydrocol- loid and plaster backing in the usual manner and pour a cast in quick-setting plaster (Fig. @article{Kawara2015RheologicalPO, title={Rheological properties of elastomeric impression materials for selective pressure impression technique. Dental practitioners can make the impression in a single stage (abbreviated impression) or in two stages (preliminary impression made for the purposes of diagnosis, or for the construction of a tray, followed by final impression). 2004 Dec;92(6):563-8. doi: 10.1016/j.prosdent.2004.09.010. Can we control the finger pressure, thereby choosing a particular area of the basal seat to receive excess load? Mandibular residual ridge resorption was reduced for dentures fabricated using the mucostatic impression technique compared with the selective pressure impression technique in individuals with diminished bone density.

PMID: 15343168 [Indexed for MEDLINE] MeSH terms Figure 21-1 Use of an existing Kennedy Class I removable partial denture base as a tray during a reline impression. A dental impression is a negative imprint of hard (teeth) and soft tissues in the mouth from which a positive reproduction (cast or model) can be formed. The effect of osteoporosis on residual ridge resorption and masticatory performance in denture wearers.
