Knife edge with movable mucosa D. When sharp bony spicules are present in the ridge Ans: A. special tray is made with 2 mm spacing. 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. If the degree of mucosal displacement is minimal, one part impression technique or selective perforation tray technique may be considered (4). Many impression techniques have been proposed to overcome these difficulties. A spaced special tray for an Impression Compound Impression Is then constructed on this model. Keywords: flabby ridges, complete denture, window impression technique 1. The purpose of this paper is to describe an impression technique for mandibular flabby ridges. Impression techniques may be classified depending on: Amount of pressure used 1. Oral status and prosthetic factors related to residual ridge resorption in elderly subjects. Impression techniques for management of flabby ridges in complete dentures – A review. The selective pressure impression technique combines aspects of both mucostatic and functional impression techniques. Ø Two techniques were developed for the management of flabby ridge. The use of selective pressure or minimally displacive impression techniques should help to overcome some of these limitations. A not-yet-reported attempt was made at recording the flabby ridge in its undistorted form, by means of a two-stage impression technique, with window modification made in stock and custom trays. Window opening of impression tray. Impression is basically an interaction between tissues and impression material. It was simple and economical to modify and increase the efficacy of an already-well-established impression technique. to compress the loose flabby tissue to allow functional support from it by replicating the ridge contour of the ridge during compression by occlusal forces. In the present case, the impression technique adopted for making of the final impression of the maxillary arch was first described by Osborne in 1964 for use in ⦠Conflicts of interest Rationale behind it was that as the patient functioned, the denture would move forward, returning the tissues to original form 5 BOUCHER introduced a method of impression technique- âSELECTIVE PRESSURE TECHNIQUEâwww.indianentalacademy.com 8. palatal splinting using a two-part tray system. Liddlelow described a technique whereby two separate impression materials are used in a custom tray (using 'plaster of Paris' over the flabby tissues, and zinc oxide and eugenol over the 'normal' tissues). Acta Odontol Scand 1997;55:306-13. This impression philosophy is credited to Boucher 5 and is based on a histologic understanding of the supporting tissues. It also acts as a stopper for the tray in the nal impression procedure. Making of final impression of flabby tissue with minimal or no displacement of tissue and better stability of denture. 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. 8 This method is based on the histological anatomy of the supporting tissues. #MCQ 19 - Selective Pressure Impression Technique is indicated in: A. London: Quintessence; 1996. The use of selective pressure or minimally displacive impression techniques should help to overcome some of these limitations. Special impressions often involve window technique for static impression of flabby area, which present multiple challenges. impression technique avoids side effects of flabby ridges and with its use we can make a complete denture with supported retention and stability. Many authors have proposed selective pressure impression techniques for flabby ridge impressions by modifying custom tray by window cut through, vent holes, and spacer or combination. Pressure technique 2. Step by step procedure for final impression including border moulding using sectional manual technique and wash impression with ZnOE impression paste. Extension for maximum coverage within tissue tolerance. With modified impression techniques, these ridges can be managed effectively without any additional clinical visits as compared to patients with normal edentulous ridges. It involves making of a primary impression by mixing impression compound and Greene stick compound in the ratio of 3:7. Functional impression can be used very effectively to create stability in cases exhibiting extreme resorption. impression technique can be overcome by selective pressure or minimally displacive impression technique. Keywords: Flabby ridge, hyperplastic soft tissue, McCord and Ahmad technique. An impression technique is required which will compress the non flabby tissues to obtain optimal support and at the same time, will not displace the flabby tissues. * Mucostatic impression technique, which aims to achieve support from the other firm areas of the arch and maximizes retention. University, Varanasi, Uttar Pradesh, India 2 Post Graduate Student, Department of The impression technique modification reported here enabled us to Prosthodontics, Faculty of Dental Sciences, make minimal-pressure impressions of flabby ridges at both the Institute of Medical Sciences, Banaras Hindu preliminary and the final impression stages. Management of flabby ridge case: An arduous task in undergraduate practice The impression technique modification reported here enabled us to make minimal-pressure impressions of flabby ridges at both the preliminary and the final impression stages. Conclusion Managing a patient with flabby maxillary ridge can be a challenging problem. A primary Impression Is taken in a mucostatic Impression material (e. g. Impression plaster or alginate) and cast in stone. Inadequate support, stability and retention of complete denture are the problems encountered in these patients. Ideas of impression making are based, particularly for hypermobile tissues, on principle of pressure (6). Case Rep Dent 2014;2014:104541. A multitude of impression techniques have been described for overcoming the problem of the flabby ridge. Subsequently, the denture will maintain its peripheral seal during function. impression technique with window preparation in stock trays and subsequent custom trays to record flabby ridges and displaceable areas. Firm healthy mucosal covering over the ridge Mucostatic Impression Technique is indicated for options B,C and D. Sankeshwari B. The selective-pressure impression technique combines aspects of both techniques, as pressure is applied to certain tissues while other areas are captured with minimal pressure. The techniques used for making final impression The basic differences in techniques for final impressions can be resolved as those that record the soft tissues in a: Functional position (Closed mouth technique, Pressure technique) Rest position Nonpressure technique (Passive technique, Mucostatic technique). The choice of impression materials and design of the custom tray used for making final impression to reduce the pressure on the displaceable tissue is very important. But in some clinical situations where the mucosa over the ridge or the palate is hyperplastic or flabby, severe undercuts, tori, etc. #MCQ 19 - Selective Pressure Impression Technique is indicated in: A. 6. Selective pressure technique. In literature, there are many impression techniques for flabby ridges. It is infeasible to register flabby tissue in an unstrained position, as meager introduction of trays and exertion 8. controlled lateral pressure technique. Firm healthy mucosal covering over the ridge Mucostatic Impression Technique is indicated for options B,C and D. Br Dent J 2000;188:484-92. The result is a composite material exhibiting greater flowability and hence better recording of details. Saudi Dent J 2018;30:89. Note distortion of left alveolar ridge lingually due to pressure exerted by irreversible hydrocolloid impression material. Tripathi A(1), Singh SV(2), Aggarwal H(3), Gupta A(4). Minimal pressure technique 3. Lynch CD, Allen PF. The impression techniques Following are the different impression techniques that can be used for resorbed mandibular ridges: The functional impression technique. Br Dent J 2005;199:715-9. 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. techniques, flabby ridge adversely affects support, retention and stability of denture. The selective pressure impression technique where denture bearing tissues are selectively displaced and relieved. The use of selective pressure or minimally displaced impression techniques should help to overcome some of these limitations. Our method for making impressions should be based on the basic principles of maximum area coverage and intimate … J Prosthet Dent 1998;79:17-23. In this paper, the authors have proposed a newer technique of impression making of the flabby tissues using a combination of readily available newer and older materials to ensure an accurate and easy impression of these tissues. Neutral zone impression technique. Controlled lateral pressure technique has been advocated by … selective pressure impression techniques for flabby ridge impressions by modifying custom tray by window cut through, vent holes, spacer or combination. III. It can develop when hyperplastic soft tissue replaces the alveolar bone and is a common finding particularly in the upper anterior region of long-term denture wearers. Conclusion Managing a patient with flabby maxillary ridge can be a challenging problem. 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.

Impression technique for Flabby ridge: Flabby ridge: a ridge that becomes displacable due to fibrous changes. Standard mucocompressive impression techniques are likely to result in an unretentive and unstable denture as the denture constructed on a model of the flabby tissue in a distorted state. presence of flabby ridge tends to create a difficulty while making complete dentures. Pai UY, Reddy VS, Hosi RN. 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. Br Dent J 2006;200:258-61. Step by step procedure for final impression including border moulding using sectional manual technique and wash impression with ZnOE impression paste. used if marked flabbiness exists ( advanced flabbiness) primary impression taken with alginate. Earlier studies show that prevalence of flabby ridges vary in either arches, with edentulous maxillae prevalence being 24% and edentate mandibles 5% [2, 3]. The British Society for the Study of Prosthetic Dentistry. Patients with flat ridge have less retention and stability for full denture. Minimal pressure technique 3. denture. A Single Step Impression Technique of Flabby Ridges Using Monophase Polyvinylsiloxane Material: A Case Report UmeshY.Pai, 1 VikramSimhaReddy, 2 andRushadNarimanHosi 2 ... remaining borders of impression were recorded by selective pressure technique using green stick compound (Pinnacle tracing stick, DPI, Mumbai, India) ( Figure ). Bansal R, Kumar M, Garg R, Saini R, Kaushala S. Prosthodontic rehabilitation of patient with flabby ridges with different impression techniques. Open mouth 2. 1st technique – it was of muco compressive type compound impression which displaced the flabby tissue paratally. 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. A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. Thus this technique helps in maximizing the functional support from h ed nul osr ig. Preliminary cast. 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. Selective Displacement / Selective Composition Flaming Technique 1) SELECTIVE IMPRESSION TECHNIQUE. Therefore, a primary impression was performed with irreversible hydrocolloid with a dual impression. selective pressure impression techniques for flabby ridge impressions by modifying custom tray by window cut through, vent holes, spacer or combination. An impression technique is required which will compress the non flabby tissues to obtain optimal support and at the same time, will not displace the flabby tissues. 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.

Fibrous or flabby ridge is a mobile or extremely resilient alveolar ridge which becomes displaceable due to fibrous tissue deposition. Dr.Yusr Mady 8,126 views. A definitive impression technique using both impression wax and vinyl polysiloxane impression material for displaceable mandibular residual ridges is described. In this simple technique for making wash impression of highly displaceable maxillary anterior ridge with low-viscosity polyvinyl siloxane and zinc oxide eugenol, impression material is explained. A close fitting custom tray and high viscosity impression for a flabby ridge the patient would usually complain of poor comfort and a âlooseâ denture. Masticatory forces can displace this mobile denture-bearing tissue, leading to altered denture positioning and loss of peripheral seal. Tunnel technique-mainly for mandibular flabby ridges. two part impression technique: mucostatic selective composition flaming. 2nd technique – it was advocated by Greene Brothers, which captured the tissue in its passive form. Close mouth Based on the method of manipulation for border molding. Methods applied for flabby ridge management, include surgical removal and augmentation, special impression techniques, balanced distribution of occlusal loads and implant therapy. The neutral zone technique. This present study describes an impression technique to rehabilitate patients with flabby ridge in pre-maxilla through complete dentures. Selective pressure technique Selective Pressure Impression Method use those portions of the residual ridge that can withstand additional stress (primary stress bearing area) and at the same time relieve the tissue of the residual ridge that cannot withstand functional loads. ý{¦SLW¨g`SG =GFÄ¡Ì ¹ó³;x¬Ac©QSd.HrÃÇë+dîj2\x0¶'e½pßn÷JZ6[l¿+©p3gþµçkg5%û/ÒÆ;\gº(¶\MP2ð 2~ãRGª+û,[æ¾z±Xïv½»qE¯©+)ârW.
