However, when the mucosa is easily displaced, the open-mouth selective pressure technique is preferable. 0000007409 00000 n For seating velocity of the impression tray, Hyde et al. Selective pressure was the predominantly used impression philosophy (80%). The selective pressure maxillary impression: A review of the techniques and presentation of an alternate custom tray design 0000637032 00000 n This article describes a selective-pressure impression technique for the edentulous maxilla that is intended to compensate for the polymerization shrinkage of heat-polymerized polymethyl methacrylate resin and provides improved palatal adaptation of the definitive denture base.

Part III: Support. 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. 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.

Many phenotypic variations are neutral, which means that they don't give organisms a benefit or disadvantage when it comes to survival and reproduction. Complete Denture Prosthetics. An impression in complete dentures is the first step in the fabrication of the complete denture prosthesis. Selective Pressure Impression (Boucher) In this technique, the impression is made to extend over as much denture-bearing area as possible without interfering with the limiting structures at function and rest. Selective pressure technique. 0000637803 00000 n In this study selective pressure impression technique and neutral zone have been compared. The objectives and principles of impression-making have been clearly defined. In the first stage, the practitioner makes a preliminary impression with a rigid or elastic material using the one-step technique.After the material sets, the impression is sent to the dental laboratory. �f��-��F&�[�8?�` �e`0 hF' endstream endobj 81 0 obj 184 endobj 32 0 obj << /Type /Page /Parent 19 0 R /Resources 33 0 R /Contents 42 0 R /MediaBox [ 0 0 581 780 ] /CropBox [ 0 0 581 780 ] /Rotate 0 >> endobj 33 0 obj << /ProcSet [ /PDF /Text ] /Font << /F1 51 0 R /F2 47 0 R /TT1 39 0 R /TT3 37 0 R /TT4 41 0 R /TT6 44 0 R /TT7 58 0 R >> /XObject << /Fm2 79 0 R >> /ExtGState << /GS1 67 0 R /GS2 59 0 R >> /ColorSpace << /DefaultCMYK 36 0 R /Cs8 36 0 R /Cs9 35 0 R /Cs10 55 0 R /Cs11 46 0 R >> >> endobj 34 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 0 /Descent -216 /Flags 34 /FontBBox [ -558 -307 2000 1026 ] /FontName /ODKPMB+TimesNewRoman,Bold /ItalicAngle 0 /StemV 133 /FontFile2 71 0 R >> endobj 35 0 obj [ /Separation /RTF#20r19#20g1#20b124 36 0 R 65 0 R ] endobj 36 0 obj [ /ICCBased 63 0 R ] endobj 37 0 obj << /Type /Font /Subtype /TrueType /FirstChar 49 /LastChar 53 /Widths [ 456 456 456 0 456 ] /Encoding /WinAnsiEncoding /BaseFont /ODKPKB+SP_Herald_Narrow,Bold /FontDescriptor 40 0 R >> endobj 38 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 0 /Descent -216 /Flags 34 /FontBBox [ -568 -307 2000 1007 ] /FontName /ODKODI+TimesNewRoman /ItalicAngle 0 /StemV 0 /FontFile2 60 0 R >> endobj 39 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 232 /Widths [ 250 0 0 0 0 0 778 0 333 333 0 564 250 333 250 278 500 500 500 500 500 500 500 500 500 500 278 0 0 0 0 0 921 722 667 667 722 611 556 722 722 333 389 722 611 889 722 722 556 0 667 556 611 722 722 944 722 722 611 0 0 0 0 0 0 444 500 444 500 444 333 500 500 278 278 500 278 778 500 500 500 500 333 389 278 500 500 722 500 500 444 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 333 444 444 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 535 ] /Encoding /WinAnsiEncoding /BaseFont /ODKODI+TimesNewRoman /FontDescriptor 38 0 R >> endobj 40 0 obj << /Type /FontDescriptor /Ascent 910 /CapHeight 0 /Descent -312 /Flags 32 /FontBBox [ -139 -217 873 938 ] /FontName /ODKPKB+SP_Herald_Narrow,Bold /ItalicAngle 0 /StemV 133 /FontFile2 68 0 R >> endobj 41 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 121 /Widths [ 250 0 0 0 0 0 0 0 0 0 0 0 0 0 250 0 0 500 500 0 0 0 0 0 0 0 333 0 0 0 0 0 0 722 667 722 722 667 611 0 778 389 0 778 667 944 722 778 0 0 722 556 667 722 0 0 0 0 0 0 0 0 0 0 0 500 0 444 556 444 333 500 556 278 0 0 278 833 556 500 556 0 444 389 333 556 0 722 0 500 ] /Encoding /WinAnsiEncoding /BaseFont /ODKPMB+TimesNewRoman,Bold /FontDescriptor 34 0 R >> endobj 42 0 obj << /Length 2911 /Filter /FlateDecode >> stream 0000002466 00000 n qL��P�7���mZnjI� ��.

An impression in complete dentures is the first step in the fabrication of the complete denture prosthesis. Another type of impression technique is selective pressure technique in which stress bearing areas are compressed and stress relief areas are relieved such that both the advantages of muco static and muco compressive techniques are achieved.

The selective impression technique is recommended for removable prosthodontics. This article describes a selective-pressure impression technique for the edentulous maxilla that is intended to compensate for the polymerization shrinkage of heat-polymerized polymethyl methacrylate resin and provides improved palatal adaptation of the definitive denture base. 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. ] 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. 0000004423 00000 n Firm healthy Mucosal covering over the ridge B.
