Abstract
Background: The presence of flabby or displaceable residual ridge tissue presents a significant challenge during complete denture fabrication because conventional impression techniques often compress the mobile tissues, resulting in inaccurate impressions, compromised denture stability, poor retention, and patient discomfort. Various impression techniques have been proposed to minimize tissue distortion during impression making. Among these, the window impression technique enables selective recording of the flabby tissues in a mucostatic state while adequately supporting the remaining denture-bearing tissues.
Case Presentation: A completely edentulous patient presented with a flabby ridge involving the anterior mandibular residual ridge. Clinical examination revealed excessive mobility of the anterior alveolar mucosa extending from canine to canine. A treatment plan involving conventional maxillary complete denture fabrication and mandibular complete denture fabrication using the window impression technique was formulated. A custom tray with a window corresponding to the flabby tissue was fabricated. Border molding and final impression of the normal denture-bearing areas were completed using zinc oxide eugenol impression paste. The flabby tissue was subsequently recorded separately through the tray window using impression plaster without tissue displacement. Master casts were obtained, followed by conventional jaw relation, teeth arrangement, trial evaluation, processing, insertion, and post-insertion adjustments.
Results: The completed dentures demonstrated satisfactory retention, stability, support, and border seal. The mandibular denture exhibited minimal displacement during functional movements. The patient reported significant improvement in mastication, speech, comfort, and overall satisfaction during follow-up visits.
Conclusion: The window impression technique combined with impression plaster remains a simple, economical, and highly effective method for recording flabby ridges. Selective management of mobile tissues while preserving the morphology of the supporting tissues contributes to improved denture fit and patient satisfaction.
