A gentle alternative: Managing flabby ridges with a liquid-supported denture

An ideal complete denture must achieve a delicate balance between rigidity and resilience. The polished surface should possess adequate strength to resist masticatory loads, while the tissue-bearing surface should provide cushioning and flexibility to ensure uniform stress distribution. Conventional acrylic dentures, being entirely rigid, frequently transmit occlusal loads unevenly, resulting in mucosal trauma, discomfort, and progressive alveolar bone resorption. This problem is accentuated in patients with flabby or atrophic ridges, where mobile fibrous tissue distorts under pressure, compromising denture stability and retention.The liquid-supported denture concept offers a biologically compatible solution that integrates a rigid acrylic base with a flexible, fluid-filled interface capable of dynamic adaptation to functional stresses. By incorporating a thin polyethylene sheet and a viscous liquid such as glycerin, the system enables equalized stress transmission, reduced mucosal distortion, and enhanced comfort.This report describes the clinical and laboratory procedures involved in fabricating a liquid-supported complete denture for a 72-year-old male patient presenting with a flabby anterior maxillary ridge. The steps—from impression making and spacer adaptation to final sealing and patient evaluation—are explained in detail. The outcome demonstrated improved retention, stability, and patient satisfaction. The liquid-supported denture thus represents a conservative yet effective alternative for prosthodontic rehabilitation of compromised ridges where surgical or implant options are unsuitable.
