Fabrication of any dental prosthesis over a compromised residual alveolar ridge is really a challenge for prosthodontists. Fibrous or flabby ridge and highly resorbed residual alveolar ridge are two clinical situations that require special considerations during construction of any prosthesis. Mobile soft tissue and flattened alveolar ridge significantly compromise denture stability and support. There are different treatment modalities to manage these clinical conditions like surgical excision of soft tissue, ridge augmentation, modification in impression technique, etc. Prosthodontic management of a patient with compromised residual alveolar ridges needs special consideration. Selection of treatment modality depends on patient’s general health, clinical condition of residual alveolar ridges, financial capacity and skill of the clinician. A modification from conventional impression procedure was used to record maxillary flabby anterior ridge and neutral zone concept was applied for teeth arrangement to improve denture stability in atrophied lower alveolar ridge. This case report is about an old completely edentulous male patient who reported with a complaint of difficulty in chewing with his present denture.
