‘Stability’ in Complete Dentures- An Interpretive Review
Dr. B. Lakshmana Rao1*
Abstract
For complete dentures to be functionally successful, comfortable for patients, and maintain long-term oral health, stability is essential, especially for mandibular dentures where functional and anatomical challenges are significant. Retention, occlusal balance, residual ridge anatomy, muscle dynamics, salivary adhesion, and polished surface contours are some of the factors that affect stability, which is defined as the denture’s capacity to withstand displacement by functional and parafunctional forces. By influencing the peripheral seal and muscle balance, the position and size of the tongue, frenal attachments, sulcus depth, and lateral throat form all have a major impact on the stability of mandibular dentures. While nonkeratinized mucosa supports the seal in dynamic areas, keratinized mucosa offers a stable load-bearing base. If precise impression techniques, neutral zone alignment, and patient education are not used to manage stresses like masticatory, muscular, parafunctional, gravitational, and salivary forces, dentures may become unstable. Stability is increased by making sure appropriate occlusal schemes are used and by optimizing flange extension into regions such as the retromylohyoid space. Implant-supported dentures might be an option for difficult cases. Oral tissue preservation, patient satisfaction, and functional efficiency are all guaranteed by effective management of these variables.
