Flabby ridges are a common challenge in the prosthetic rehabilitation of edentulous patients. These mobile, hyperplastic tissues compromise denture stability and retention, leading to patient discomfort and functional limitations. This case report describes the management of an 81-year-old edentulous patient presenting with flabby maxillary tissues. The proposed treatment included a combined surgical and prosthetic approach. A specific impression technique was used to accurately record the flabby tissues with minimal displacement, employing selective pressure. Surgical intervention involved vestibuloplasty and excision of the hyperplastic mucosa, guided by a transparent duplicate of the prosthesis serving as a surgical guide. Post-surgical stabilization was achieved using a tissue conditioner applied to the final prosthesis, which was placed immediately after surgery. The healing process was monitored at regular intervals, and satisfactory outcomes were obtained with prosthesis stability, and patient satisfaction. This case illustrates the value of a multidisciplinary approach combining careful diagnosis, patient-specific impression techniques, and surgical precision to manage flabby ridges effectively and restore prosthetic function in edentulous patients.
