Denture retention refers to the ability of a dental prosthesis, known as dentures, to resist movement or displacement within the mouth during functional activities such as biting, chewing, and speaking. It is a critical factor in ensuring the comfort, stability, and functionality of dentures.
Dentures are custom-made removable appliances designed to replace missing teeth and restore a person's ability to eat, speak, and smile. However, without proper retention, dentures may become loose, unstable, or dislodged, leading to discomfort, difficulty in eating, speech impairment, and reduced overall confidence.
The retention of dentures primarily relies on various factors, including the physical characteristics of the dentures themselves, the underlying oral tissues, and the oral muscles. Dentures are typically made of acrylic or a combination of acrylic and metal, and their design should consider factors such as fit, occlusion, contour, and overall aesthetics.
Meanwhile, the oral tissues play a vital role in denture retention, particularly the underlying jawbone and gums. The bony ridge and gums that support the dentures should have sufficient volume and shape to hold the prosthesis securely in place. If the supporting tissues are insufficient or undergo changes over time, it may affect the retention of dentures.
Furthermore, the oral muscles, including the cheek and tongue muscles, contribute to denture retention. They provide counteracting forces and help stabilize and maintain the position of the dentures during various oral activities.
To ensure optimal denture retention, regular check-ups with a dentist or prosthodontist are essential. They can assess the fit and function of the dentures, make necessary adjustments, and recommend appropriate denture adhesives or relines when needed.
