Modified impression technique for flabby ridge using sectional magnet retained custom tray

Abstract

Alveolar ridges that are movable or extremely resilient, which become displaceable due to fibrous tissue deposition are known as fibrous or flabby ridges. These patients suffer from inadequate support, stability, and retention of a complete denture. Making final impression for these ridges often used window technique which involved painting of impression plaster for mucostatic recording of fibrous region but it is difficult to handle. This case report proposes a technique that uses the integration of magnets to fabricate a segmented custom tray to allow mucostatic impression for flabby ridge by polyvinylsiloxane light body material followed by wash impression with zinc oxide of the remaining palate.
