The purpose of this paper is to describe an impression technique for mandibular flabby ridges. 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. A multitude of impression techniques have been described for overcoming the problem of the flabby ridge. Pressure technique 2. Minimal pressure technique 3. Hand manipulation 2. Many impression techniques have been proposed to overcome these difficulties. Carlsson GE. Extension for maximum coverage within tissue tolerance. Patients with flat ridge have less retention and stability for full denture. 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. The selective pressure technique makes it possible to confine the forces acting on the denture to the stress-bearing areas. relieve displaceable areas, and load primary stress bearing areas peripheral seal ... flabby tissue NVS bundles thin mucosa knife edge ridges.

The impression techniques Following are the different impression techniques that can be used for resorbed mandibular ridges: The functional impression technique. Subsequently, the denture will maintain its peripheral seal during function. Impression making of flabby ridge results in ... using selective composition flaming technique. the effect of impression technique and impression material on denture ... 1. Flabby Ridge. Selective pressure technique Based on the position of the mouth while making impression 1. Making of final impression of flabby tissue with minimal or no displacement of tissue and better stability of denture. two part impression technique: mucostatic selective composition flaming. 8. Step by step procedure for final impression including border moulding using sectional manual technique and wash impression with ZnOE impression paste. Figure 8: Final impression except flabby ridge area ... placement of the stock impression tray with finger pressure caused excess tissue displacement of maxillary residual ridge. Lynch CD, Allen PF. This technique is quite useful in poor ridge cases. The use of selective pressure or minimally displacive impression techniques should help to overcome some of these limitations. A major consideration of treating flabby tissues is impression making, two theories have been suggested for impression making: * Mucodisplacive impression technique, with the aim of compressing the loose flabby tissue to allow functional support from it by replicating the contour of the ridge during compression by occlusal forces. ... also known as selective pressure technique. * Mucodisplacive impression technique, with the aim of compressing the loose flabby tissue to allow functional support from it by replicating the contour of the ridge during compression by occlusal forces. The proposed technique consists on the association of nondisplacive impression of the flabby area in the primary and functional impression. Making of final impression of flabby tissue with minimal or no displacement of tissue and better stability of denture. A definitive impression technique using both impression wax and vinyl polysiloxane impression material for displaceable mandibular residual ridges is described. Thus, over the years, several impression techniques have been suggested for the impression of a flabby tissue ridge which will support the flabby tissue but at the same time will not displace it. impression technique Kawabe, divided into 2 stages: (1) preeliminary impression is made using a technique which is mucostatic charateristic or non-pressure impression, and (2) the physiological impression uses selective pressure impression technique. Clinical morbidity and sequelae of treatment with complete dentures. Duncan JP(1), Raghavendra S, Taylor TD.
