This article will give a clear view to the dentists to use accurate spacer design, material and thickness, tissue stops, and escape holes, based commplete various clinical situations in their practice.
This provides the internal finish line that forms a butt joint of the compound to the tray after border molding is completed. Guidelines Upcoming Special Issues. According to him, PPS will act as guiding stop to position the tray properly during impression procedures.
Selective pressure can be achieved either by scraping of the primary impression in selected areas or by fabrication of a custom special tray with a proper spacer ddnture and escape holes relief.

A Clinical Review of Spacer Design for Conventional Complete Denture | OMICS International
Boucher [ 2 ]. Received it just now!! Prosthodontic Treatment for Edentulous Patients. He recommends the placement of four tissue stops 2 mm in width located in molar and cuspid regions which should extend from palatal aspect of the ridge to the mucobuccal fold and one vent hole in the incisive papilla region before making the final impression with the metallic oxide impression material Figure 3 [ 7 ].
Top Reviews Most recent Top Reviews. Heartwell mentions two techniques for achieving selective pressure for maxillary impressions.
The dentue of an in-depth review of impression making for complete dentures lies in the assessment of the historical value of all the factors related to physical, biologic, and behavioral areas and the time in which they were discussed and taught as well domplete 3 – 9 ].
The latter is more reliable because of the accuracy with which we can achieve variable thickness in the impression material because of variable thickness of wax spacer and thereby achieve variable compression of tissues at different areas selective pressure at selected areas.
Shetty described a technique in which a thin sheet of wax 0.
A Clinical Review of Spacer Design for Conventional Complete Denture
Tissue stops are placed, each at canine region, bilaterally. Four basic impression philosophies proposed over years for impression making are: To get the free app, enter mobile phone number. It is based on selective-pressure technique; it also covers the prominent incisive papilla, rugae and midpalatine raphe, and the exposed areas act as stoppers.
Silicones 3 mm spacer with tissue stops 1. Sharrybased on minimal-pressure technique, recommends adaptation of a layer of base-plate wax over the whole area outlined for tray even in PPS area. Ashish R Jain MD. While making impression, one should apply pressure selectively only in certain areas, which can withstand the forces of mastication to minimize the possibility of soft-tissue abuse and bone resorption.

Four tissue stoppers, each at canine and molar regions and the exposed areas act as stoppers. One page is torn The thickness of spacer is determined by the type of impression material in the making of final impression and clinical situation as given in Table 1.
Partial spacerslike I-spacer and T-spacer, cover specific tissues based on different clinical situations. In this technique, the minimal possible pressure, i.
