With modified impression techniques, these ridges can be managed effectively without any additional clinical visits as compared to patients with normal edentulous ridges. Pressure technique 2. A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. Special impressions often involve window technique for static impression of flabby area, which present multiple challenges. Hand manipulation 2. Fibrous or flabby ridge is a mobile or extremely resilient alveolar ridge which becomes displaceable due to fibrous tissue deposition. 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. Methods applied for flabby ridge management, include surgical removal and augmentation, special impression techniques, balanced distribution of occlusal loads and implant therapy. Functional impression can be used very effectively to create stability in cases exhibiting extreme resorption. The result is a composite material exhibiting greater flowability and hence better recording of details. impression technique can be overcome by selective pressure or minimally displacive impression technique. 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. The selective pressure impression technique where denture bearing tissues are selectively displaced and relieved. The admixed technique. 2nd technique – it was advocated by Greene Brothers, which captured the tissue in its passive form.
