Flabby ridge is a common clinical finding that affects the alveolar ridge in both the mandibular and maxillary arches. The anterior region of the maxilla is the most commonly affected area in edentulous patients. Dentures fabricated over flabby ridges often exhibit compromised stability, poor support, and inadequate retention. Management includes surgical intervention, specialized impression techniques, redistribution of occlusal loads, and implant therapy. Among these, the window impression technique is employed to record flabby tissues in a static, undistorted state. However, these techniques present several clinical challenges. This case report presents a modified window technique for accurately recording anterior maxillary flabby tissue, allowing controlled application of light-body polyvinyl siloxane (PVS) impression material and improved clinical outcomes. This technique was adapted using a previously reported method (Zafarullah Khan's technique), with precise cutting of the window after the zinc oxide eugenol impression set, ensuring no damage to the primary impression.
