| Summary: | In the case of old mobile denture wearers, one of the main problems is related to the dentures’ retention and insufficient stability. Our goal was to improve support and stability using a different type of final impression, with different types of impression materials. In this study we chose a number of three complete edentulous patients who presented for complete oral rehabilitation. They were wearing full acrylic dentures with poor support and stability. Complete examination revealed the presence of the flabby ridge. The impression methods for the prosthetic fields with a flabby ridge differ from the classical method by using techniques that involve the use of at least two impression materials with fluid consistency to record all the details of the prosthetic fields in the final impression, this being done in two steps; the impression of the flabby ridge areas must be done without pressure, in its resting position. The impression methods we applied led to the expected results, and the dentures succeeded in offering the patient the desired functional comfort. Using fluid impression material for the flabby ridge in a resting position, and a fenestrated custom tray, offered a good quality in adaptation, maintenance and stability of the final dentures.
