Electrospun multilayer denture pad with enhanced adhesion and comfort
Introducing a multilayer denture pad made from electrospun mucoadhesive polymers, designed to improve denture security and comfort. This innovative solution offers controlled hydration, strong adhesion, and easy removal by separating hold, seal, and removability into distinct material functions.
Overview
The University of Alberta introduces an innovative multilayer denture pad, leveraging electrospun mucoadhesive polymers to enhance denture security and user comfort. This advanced design aims to deliver a secure, comfortable, and natural-feeling fit by integrating a mucosa-contacting wet-adhesive layer, a saliva-responsive viscoelastic "gasket" layer, and a barrier/handling layer. These layers work together to provide controlled hydration, robust interfacial contact, and easy removal, addressing common denture adhesive issues such as messiness and residue formation.
Technical specifications
Key features:
- Mucosa-contacting wet-adhesive layer: Ensures strong adhesion to the gums.
- Saliva-responsive viscoelastic gasket layer: Hydrates and conforms to the denture-gum microgap, enhancing comfort and sealing.
- Barrier/handling layer: Minimizes oozing and facilitates clean removal.
- Electrospun architecture: Allows for precise control over fiber composition, layer thickness, porosity, and hydration response.
The proposed pad undergoes extensive testing phases, focusing on optimizing saliva-triggered activation, retention/separation force, and user experience metrics to ensure practical applicability and comfort.
Technology readiness level
This technology is currently at Technology Readiness Level 2, indicating that the concept has been formulated and initial proof-of-concept work has been completed. Future validation includes further prototype development, performance evaluation, and user experience assessments to advance towards commercialization.
