flat ridge impression technique

As resorption continues from the labial and lingual aspects, the crest of the ridge becomes increasingly narrow ultimately becoming knife-edged (order IV).As the process continues,the knife-edge becomes shorter and eventually disappears, leaving a low well rounded or flat ridge … Order 5 to order 6: final stage. These impressions will generally lead to a denture which has a good fit … A dentist should understand the factors causing the residual ridge resorption and treat the patient accordingly using the different treatment options. These prosthetic factors include broad coverage area, decreased number of dental units, decreased buccolingual width of the teeth, improved tooth form, avoidance of inclined planes, centralization of occlusal contacts, adequate interocclusal distance during rest jaw relation. A final impression with monophase (medium body) (Aquasil LV Monophase, Dentsply Caulk) addition silicone was made (Figure 11). The relief wax was removed and multiple holes were drilled in the “supporting tray (Figure 14).” Placement of multiple relief holes was done to ensure prevention of pressure build-up in the flabby area thereby leading to inadvertent tissue compression. Copyright © 2014 Umesh Y. Pai et al. The method uses functional impressions in existing maxillary and mandibular dentures to create master casts and to act as stabilized carriers for jaw relation records. The denture sits on teeth “pilings”, enabling the denture to withstand a much greater occlusal load without movement. Once set, a low viscosity mix of impression plaster is then painted onto the flabby tissues through the window. Flabby ridge also called as fibrous ridge or displaceable ridge is mobile soft tissue present on the superficial aspect of the alveolar ridge. In the United States, posters, cartoons, songs, and other popular culture were designed to mobilize the entire home front, to make every … Fig.3: Refined primary impression. The advantage of choosing monophase impression material is that, due to the inherent nature of the material, different consistencies can be achieved by varying the pressure applied on the material during mixing. Many newer materials, such as polyvinylsiloxanes, are currently available in the market with varying consistencies and dispensing methods to suit the dental practitioner. If endosteal bone growth fails to keep pace with external osteoclastic activity, then medullary bone would be exposed resulting in defects on the crest of the ridge. Lynch and Allen [10] advocated the use of impression compound over the buccal shelf area for recording impressions in distal extension partial denture ensuring a stable and uniform contact on the buccal shelf area, which in this case is the primary stress bearing area. Latents have been successfully used to identify suspects in criminal in-vestigations for over 100 years by comparing the similar-ity between latent and rolled fingerprints in a reference database [12]. When multiple impressions of a finger are available, the relative distortion between one pair can be significantly different from another pair (Fig. A NOVEL IMPRESSION TECHNIQUE FOR FLABBY RIDGE MANAGEMENT IN EDENTULOUS PATIENTS – A CASE REPORT: Nidhi Beria,Rajeev Singh,Asha M. Rathod,Gaurang Mistry,Charusheela Sardar: INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH. We don’t come across the ideal ridge in complete denture patients. [6, 7] described a two-tray impression technique where two trays are fabricated and impression is recorded with two different materials and is then oriented intraorally. According to GPT-7, “residual ridge resorption is a term used for the diminishing quantity and quality of the residual ridge after the teeth are removed.”, Atwood classified residual ridge resorption into: Order 1: pre-extraction Order 2: post-extraction Order 3: high, well-rounded Order 4: knife-edged Order 5: low, well rounded Order 6: depressed. Residual ridge resorption is a localized loss of bone structure. Over the “open” area of the tray another “supporting tray” of clear acrylic was made thus covering the flabby ridge. The techniques of persuasion that helped to shape the modern world were developed for and during the Great War (1914-1918). Residual ridge resorption is multi factorial and biomechanical disease. Residual ridge resorption is directly proportional to bone resorption factors/bone formation factors. MAXILLARY HYDROXYAPATITE AUGMENTATION Eliminates the need for donor site surgery & is easily placed in an outpatient setting It can be used to contour or eliminate minor ridge irregularities & undercut areas in the maxilla. In the soft tissue, varying amounts of metaplastic cartilage and/or bone have been reported [5]. This gives the patient a denture that has far more support than any conventional appliance. Keywords: Flabby ridge, hyperplastic soft tissue, McCord and Ahmad technique This paper presents case report for prosthodontic rehabilitation of a patient with flabby ridge with McCord and Ahmad impression technique. Management of a flabby ridge is mainly by three approaches:(1)surgical removal of fibrous tissue prior to conventional prosthodontics,(2)implant retained prosthesis(i)fixed,(ii)removable,(3)conventional prosthodontics without surgical intervention [6, 7]. A modified technique for edentulous flat ridge lower cases. The etiology of Residual ridge resorption being related to the deficiency of some hormone, vitamin or mineral is yet to be discovered & causally related to Residual ridge resorption. Stability of lower denture in such cases is usually becomes the determining factor between success and failure. The challenge to ensure adequate function increases manifold when confronted with denture bearing areas that are not conducive to adequate function. Thus the use of overdentures preserves the alveolar bone. Fabrication of new complete dentures was planned for the patient with recording of flabby tissue in undisplaced condition using Hobkirk technique. Neil classified residual ridge resorption in relation with the floor of the mouth and mylohyoid ridge: Class 1: 0.5 inch space exists between mylohyoid ridge and the floor of the mouth. Watt and McGregor, recently revisited by Watson [9], described a technique where impression compound is applied to a modified custom tray. Abstract. The materials are also readily available in the market and the method is easy to master and also does not require elaborate time, equipment, and auxiliary personnel thereby making it easy to be incorporated in our day to day dental practice. FLAT PALATE WITH SHALLOW RIDGES the denture may easily be displaced during mastication through lack of ridge support, the shallow sulci adversely influence peripheral seal Treatment: an impression technique incorporating careful peripheral adaptation, the use of cuspless teeth, to reduce the lateral drag from cuspal interference. The remaining borders of impression were recorded by selective pressure technique using green stick compound (Pinnacle tracing stick, DPI, Mumbai, India) (Figure 10). Local bone-resorbing factors like endotoxins, osteoclast activating factor (OAF), prostaglandins, human gingival bone- resorption stimulating factor, heparin and trauma lead to residual ridge resorption. Order 2 to order 3: external osteoclastic resorption Various techniques have been recommended and there is controversy as to whether a mucodisplacive technique which compresses the mobile tissue aiming to achieve maximum support from it or whether a mucostatic technique with the aim of achieving maximum retention should be employed. A window technique is used for impression of flabby ridge using a close fitting custom tray with a window (Watt et al., 1986). However, resorption of the posterior residual ridge was increased when compared with similar sites in the patients treated with implant-supported fixed prostheses. Bone undergoes constant remodeling throughout life. Osborne [8] described the “window” impression technique with a custom tray made with a window over the flabby tissues. Branemark classified residual ridge resorption depending on bone quality and quantity: Bone quantity Class A- Most utmost of the alveolar bone is present. Distraction is a technique that helps to orient the focus away from the trigger to the “gag” reflex. But this is labeled as a disease because of the wide variation in the rate of residual ridge resorption. Indicated when severe resorption of mandible results in inadequate height & contour & potential risk of fracture, placement of implants required. Prosthodontic literature has documented various impression techniques for overcoming the problem of the flabby ridge. The patient was not willing to undergo surgical procedures so it was decided that upper and lower complete dentures will be fabricated with a different impression technique. Typically these “flabby ridges” are composed of mucosal hyperplasia and loosely arranged fibrous connective as well as more dense collagenised connective tissues. Breathe through your nose and lift your feet off of the chair are simple and quick ways to distract the reflexive action, particularly if the first time the reflex becomes apparent is while making the impression. This technique aims to displace but not distort the flabby ridge as If In function. Magnusson et al. The impressions were poured with dental stone and the displaceable tissues were identified on the cast. Techniques for taking impression. The anterior canine-canine region in maxilla along with the maxillary tuberosity and the mandibular canine-canine region was flabby (Figures 1 and 2). Class B- Moderate residual ridge resorption occurs. Technique 1: Distraction. But there may be porosities and imperfections in the crestal areas of residual ridges of both maxilla and mandible, no matter at what stage of configuration they are. Furthermore, even in a single impression, the deformation of the ridges can vary The authors declare that there is no conflict of interests regarding the publication of this paper. If the flabby tissue is compressed during conventional impression making it will later tend to recoil and dislodge the overlying denture [2]. They include: Impression procedures for Residual ridge resorption [5] described a technique where two impression materials are used in a custom tray using zinc oxide and eugenol over the normal tissues and impression plaster over the flabby area. Flabby ridge is predominantly seen in the upper anterior region and is commonly associated with features of combination syndrome, as mentioned by Kelly [1]. Methodology: Dual surface impression technique was employed for the fitting and polished surface using silicone impression material. 7 out of 10 completely edentulous patients have resorbed mandibular ridge. 1969 Feb 4;126(3):134-5. The purpose of this paper is to describe two impression techniques used by the authors using readily available impression materials for recording the edentulous flabby tissue along with the normal tissues around it. Although tooth & implant abutment attachment mechanism differs, their prosthetic role is identical. Loss of vertical dimension of occlusion. The lesser resilient tissues can displace the dentures under masticatory load leading to loss of peripheral seal causing poor retention of the denture. (Signature of Mary Doe) Signed and sworn to before me in (Notary's Stamp (Notary's Name, County, and Date Commission Expires) lounty, Michigan, on … SELECTIVE IMPRESSION TECHNIQUE. To categorize the most common residual ridge configurations, Atwood has described the six orders of residual ridge resorption. While this impression technique is clearly less complex than the previous three described, the problem with all four techniques is that they rely on materials such as impression plaster, impression compound, and zinc oxide and eugenol. Studies on mandibular overdentures retained by implants have shown that the bone height is maintained in the area where implants were located. 2014, Article ID 104541, 6 pages, 2014. https://doi.org/10.1155/2014/104541, 1Department of Prosthodontics, Manipal College of Dental Sciences, Manipal University, Manipal, Mangalore, Karnataka 575001, India, 2Department of Prosthodontics, A B Shetty Memorial Institute of Dental Sciences, Deralakatte, Mangalore-575018, India. Over this manipulated impression compound, a wash impression with zinc oxide and eugenol is made. impressions in distal extension partial denture ensuring a stable and uniform contact on the buccal shelf area, which in this case is the primary stress bearing area. Crawford et al. It proceeds slowly over a long period of time, flowing from one order to the next order. The overdentures accomplishes three rather obvious, but tremendously important goals 1. A variety of impression techniques have been suggested for flabby ridge cases, such as using two materials on a single custom impression tray, a two-tray impression with different impression materials incorporated together intraorally, a window impression, and using impression compound on a custom tray with a wash impression material application. Vestibuloplatsies are the soft tissue surgeries performed to provide an enlarged area of fixed tissue in primary denture bearing or implant area & to improve extension in the area of denture flanges by removing the dislodging effects of muscle attachments in denture bearing or vestibular areas. technique described by Watson (12) in which a The posterior tray part was modified by wax to The history of complete denture impression procedures has been influenced largely by the development of impression materials from which new techniques and ideas arose. Now a closed mouth or open mouth technique is used to make a master impression Farrier S(1), Pretty IA, Lynch CD, Addy LD. There are five special impression techniques for taking an impression of a resorbed ridge. tion ridge impressions formed as a result of someone touch-ing a surface, particularly at a crime scene. There is a reduction in the size of the residual ridge. Transpositional Flap Vestibuloplasty (Lip Switch), Vestibule and Floor of the mouth extension procedure. A primary impression of the upper and lower arches was taken with alginate (Neocolloid; Zhermack) in the edentulous trays. 2. careful blocking out of the undercut areas on the model. Fig.6: Provision of relief for In terms of patient economics and time taken for the completion of procedure, the implant supported prosthesis has its drawbacks. FLAT LOWER RIDGE The shape of the ridge provides no resistance to lateral movements of the denture. Order 4 to order 5: more resorption Indicated in bone deficient maxilla where the palatal vault is found to be adequately formed but the ridge height is insufficient. 1 single complete denture /dental courses Indian dental academy. We are committed to sharing findings related to COVID-19 as quickly as possible. Complete denture fabrication in clinically compromised situations such as flabby ridges is a challenging task for the clinician. Class C- Advanced residual ridge resorption occurs. Impressions can also be described as mucostatic or mucocompressive, being defined both by the impression material used and the type of impression tray used (i.e. Mccord and Tyson’s technique for flat mandibular ridges is followed for a definitive impression. It also acts as a stopper for the tray in the nal impression procedure. Resin tray and occlusal rim are made and tried in the mouth 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. 4. reducing the vertical dimension in such cases may be advantageous as this reduces the force applied during mastication. They provide enhanced prosthesis retention & stability, & their influence on adjacent bone levels appears to be similar. A particular problem is encountered in the conventional impression making if a flabby ridge is present within an otherwise “normal” denture bearing area. INFERIOR BORDER AUGMENTATION Rarely used. Br Dent J. A monophase impression material was preferred as it has the desirable thixotropic property thereby ensuring adequate flow under pressure (Figure 12). Residual ridge resorption is a normal physiologic process and is not a disease. The purpose of this study was to compare the retention of complete dentures made by using different impression techniques like conventional, admixed, all green, and functional techniques. Flat ridge management 11,538 views. The treatment of a patient with prosthodontic needs can be modified according to the type of ridge present as a result of ridge resorption. The handle was placed in the palatal portion of the maxillary tray to ensure visualization of the underlying tissues through the clear acrylic tray and also to facilitate uniform distribution of pressure during impression making (Figure 7). Cast is poured KNIFE LIKE LOWER RIDGE The patients with a ridge of this type frequently complain of pain during mastication as the pressure exerted on the mandible via denture compresses the soft tissue between the fitting surface & the knife-like process forming the crest of the alveolar ridge. Resorption of the residual ridges is a natural process. The upper tray is kept properly seated in position by the operator’s thumb and index fingers. The Buccal shelf area was recorded by using mucocompressive impression material like impression compound Type 1 (Y Dents, Mumbai, India) (Figure 9). But in osteoporosis bone resorption is greater than bone formation. They are: Residual ridge resorption and anatomic factors The presence of more bone will lead to more residual ridge resorption. Aim: This article described a physiological impression technique to design denture surfaces by the action of the surrounding musculature during functional movements based on "neutral zone concept" in patients with severely atrophied mandibular ridge. Its limitations include chances of decrease in vestibular height requiring an additional surgery of vestibuloplasty. This ridge resorption can continue till only a thin cortical plate is left on the inferior border of the mandible, and in maxilla it continues till there is no alveolar process left. and functional moments were done till the impression material hardens.13 The technique proposed by Dr. Chandrasekaran Nair Irreversible hydrocolloid is used for mandibular primary impression. 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. Non-anatomic teeth should be used for the setup. 2a, b). The design of the denture should aim at reducing the amount of force on the ridge, thereby reducing residual ridge resorption. Neutral zone impression technique shaista173. An accurate impression is the foundation of a good functional prosthesis as it determines the retention and comfort of the prosthesis. The two impression techniques described in this paper requires the same amount of appointments as required for the fabrication of the normal complete denture. Uses autogenous corticocancellous blocks of iliac crest bone. Elsey HJ. Lateral cephalometric radiographs provide an accurate method for determining RRR. Once set, the entire impression is removed. In everyday dental practice one encounters patients who either believe themselves, or subsequently prove themselves, to be gaggers. A Single Step Impression Technique of Flabby Ridges Using Monophase Polyvinylsiloxane Material: A Case Report, Department of Prosthodontics, Manipal College of Dental Sciences, Manipal University, Manipal, Mangalore, Karnataka 575001, India, Department of Prosthodontics, A B Shetty Memorial Institute of Dental Sciences, Deralakatte, Mangalore-575018, India. A mucocompressive impression is first made of the normal tissues with zinc oxide and eugenol using a custom tray. Earlier studies show that prevalence of flabby ridges vary in either arches, with edentulous maxillae prevalence being 24% and edentate mandibles 5% [2, 3]. With provision of complete dentures in general dental practice in mind, an impression technique is described and illustrated. * Mucostatic impression technique, which aims to achieve support from the other firm areas of the arch and maximizes retention. Share; Like; Download ... Muaiyed Mahmoud Buzayan ... Resorbed ridge seminar koto Kushal Singh. Clinically, the soft tissues overlying the residual ridges may range from normal to inflamed, edematous, ulcerated, indented or abused tissue. 3. with the preservation of teeth for an overdenture, there is also the preservation of the periodontal membrane that surrounds these teeth. Three major factors lead to residual ridge resorption. More precise esthetic and phonetic assessments of the existing prostheses are accommodated, and prescriptive changes may be referenced to the current tooth arrangement. Umesh Y. Pai, Vikram Simha Reddy, Rushad Nariman Hosi, "A Single Step Impression Technique of Flabby Ridges Using Monophase Polyvinylsiloxane Material: A Case Report", Case Reports in Dentistry, vol. The purpose of this article is to highlight the clinical problems encountered in the treatment of edentulous patients with atrophic (flat) mandibular ridges. A spaced special tray for an Impression Compound Impression Is then constructed on this model. A good impression plays an important role in the successful treatment in cases of resorbed mandibular ridges where there is inadequate tissue to fulfil the requirement of retention, stability and support. Review articles are excluded from this waiver policy. Treatment for residual ridge resorption is of two types: Ideally, we should treat Residual ridge resorption by preventing it. This clinical case report presents a case of severely resorbed ridge managed using the cocktail impression technique to improve mandibular denture stability in an atrophic mandibular ridge. Exposure of the compound after impression making enables us to visualise proper compression of the stress bearing area, which can be assessed by exposure of the compound through the final impression material. 1. Other factors that must be considered include surgery, discomfort and inconvenience, general health of the patient, and risk of surgical complications or implant failure [4]. The current paper describes a simple technique to record flabby tissues in their undisplaced state using readily available clinical materials like polyvinylsiloxanes in varying consistencies. Until this is determined, it is essential to analyze our patients in regard to the various possible factors to best of our ability, to seek consultation concerning possible metabolic factors, & to perform prosthodontic care of our patients within our best capabilities. Complete denture fabrication in clinically compromised situations such as flabby ridges is a challenging task for the clinician. Alveolar bone exists as support of the teeth. The maxillary borders were recorded by selective pressure impression technique using green stick compound (Figure 13). Treatment: 1. an alveolectomy to reduce undercut. Due to the obvious difficulties in analysis of the success of prostheses constructed using the various impression techniques described, the clinical choice has fallen mainly to personal preference, based on analysis of theoretical principles. Class 3- a thin layer of compact bone surrounds a core of dense trabecular bone. Class E- Extreme resorption of the basal bone occurs. Accurate impressioning of these tissues plays a major role in ensuring a well-fitting prosthesis. The best of all is to prevent the loss of natural teeth. Force is the main factor in Residual ridge resorption. Treatment: 1. alveolectomy to reduce the sharp process 2. relief for the knife-like ridge area 3. construction of denture having resilient lining.
