1. Flat ridge Asdsdsa

2. What is a flabby ridge? a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. It can develop when hyperplastic soft tissue replaces the alveolar bone Allen P F, McCarthy S. Complete dentures from planning to problem solving. London: Quintessence Publishing, 2003

3. Etiology Long term denture wear without maintenance (relining or rebasing) Loose ill_fitting dentures(main cause) as well wrong centric occluding relation, occlusal disharmony and traumatic occlusion Load concentration on the anterior segment of the ridge as a result of decreased VD accompanying occlusal wear ex,dentures with anterior porcelain teeth and posterior resin teeth Complete maxillary denture opposing natural mandibular anterior teeth and partial denture Not removing denture during night to allow the basal seat mucosa toregain its resting form Unplanned extractions

4. Combination syndrome/Anterior hyperfunction syndrome Edentulous maxilla is opposed by natural mandibular anterior teet Loss of bone form the anterior portion of the maxillary ridge Overgrowth of the tuberosities Papillary hyperplasia of the hardpalates mucosa Extrusion of the lower anterior teeth Loss of alveolar bone and ridge height beneath the mandibular prosthesis The cause for this problem is usually inadequate posterior occlusion

5. Location and forms Single or multiple flaps Localized or generalized over the entire ridge crest Commonly found ,maxillary anterior region associated with amaxillary complete denture opposing natural mandibular anterior teeth without posterior Or mandibular partial denture is present but no longer provides for posterior occkusal support due to tissue changes

6. Management/ treatment Reversibility of flabby tissue: hypertrophy of the mucosa which does not include fibrous hyperplasia ,resolve when the source of trauma is removed and start arecvery program Irreversibility of flabby tissue: fibrous hyperplasia for the mucosa and necessitates surgical removal
