Rehabilitation of a completely edentulous patient with flabby tissue is a testing situation for a prosthodontist as it adversely affects retention, stability and support of complete dentures. Several impression techniques have been proposed to help overcome these difficulties encountered in such cases.  A careful consideration and application of the principles of complete denture construction for such condition can provide a palliative form of treatment. The window impression technique uses a custom tray with a window over flabby tissues and a mucostatic impression material to minimize distortion of tissues while making an impression. First, an accurate record of the denture supporting and limiting structures is made except for the mobile tissues which are recorded in second step using light body polyvinyl siloxane/impression plaster impression material in the window area of special tray. This technique helps in maintaining the contour and recording the details of the tissues without displacing the flabby tissues.
