A fibrous or flabby ridge is an easily displaced soft tissue that is not supported by alveolar bone. This lack of bone support occurs when hyperplastic tissues replace the alveolar bone, and it is generally located in the anterior maxilla. This condition does not provide good support or stability for a denture. Fabricating a complete denture for a patient with a flabby ridge requires a specific impression technique to obtain an accurate working model that will be used to produce a retentive and stable denture. 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. In this case report, the operator used a window technique impression with an impression material showing minimum changes to the ridges.
