The best management for a patient presenting with a flabby ridge is surgical removal of the flabby tissue because the mobile, fibrous tissue compromises denture stability and retention. Excision of the hyperplastic tissue creates a firm and stable foundation, allowing for better adaptation and support of the denture base. This approach prevents continuous movement during function, which soft liners or relining alone cannot fully control. Increasing vertical dimension does not address the core structural issue. Proper surgical intervention ensures long-term prosthetic success and patient comfort.
