CONSERVATIVE REHABILITATION OF SEVERELY ATROPHIC MANDIBULAR RIDGES USING LIQUID SUPPORTED DENTURES: A CASE SERIES

Abstract

Managing edentulous patients with severely resorbed ridges continues to be a clinical challenge, especially when traditional dentures fail to offer lasting comfort, retention, or stability. In such cases, surgical or implant-supported solutions may not always be practical—either due to systemic conditions like diabetes or patient-related factors such as cost or preference. Liquid-supported dentures present a promising conservative alternative that adapts to the dynamic oral environment.

This case series describes two patients with atrophic mandibular ridges who were successfully rehabilitated using liquid-supported dentures. After conventional fabrication steps, a flexible polyethylene sheet was incorporated into the mandibular denture to create space for glycerin,a biocompatible liquid that cushions the tissues during function. The denture is adapted to soft tissue movements while evenly distributing masticatory forces.

Over a 6-month follow-up, both patients reported noticeable improvements in chewing, comfort, and overall satisfaction. There were no complications such as leakage or mucosal irritation. The flexible base helped reduce trauma to the tissues and may play a role in slowing further ridge resorption.

Liquid-supported dentures combine the best of flexibility and function, offering an effective solution for patients with compromised ridges especially when more invasive approaches are not an option.
