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. Boucher CO. A critical analysis of mid-century impression techniques for full dentures. The impression material of choice for the preliminary impression was irreversible hydrocolloid (88%). The selective pressure technique makes it possible to confine the forces acting on the denture to the stress-bearing areas. However, when the mucosa is easily displaced, the open-mouth selective pressure technique is preferable. 0000471973 00000 n 1 °. 30 0 obj << /Linearized 1 /O 32 /H [ 1492 296 ] /L 654811 /E 638629 /N 3 /T 654093 >> endobj xref 30 52 0000000016 00000 n 0000003967 00000 n Various methods had been employed by the profession to overcome this problem.
