Solid Denture Adhesive Composition for Oozing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing denture adhesives face issues with premature sticking, oozing, and decreased performance due to bio-erosion and negative aesthetics, leading to discomfort and reduced denture stability.
Innovation Solution
A denture adhesive composition comprising a homogeneous mixture of 10% to 90% denture adhesive component and 20% to 70% water insoluble thermoplastic component, which is solid prior to use and provides a normalized dislodgement force of 1100 to 12,000 grams per sq.cm, minimizing oozing and improving handling and application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a low viscosity denture adhesive is used, then ease of application is improved, but oozing increases
Solution Approach 1:
The patent changes the physical state parameter of the denture adhesive from liquid/cream to solid form. This fundamental parameter change allows the adhesive to be easy to apply (can be picked up and positioned) while preventing oozing under the denture plate.
Solution Approach 2:
The patent utilizes phase transition by employing a solid denture adhesive that can be easily positioned. The solid phase provides structural integrity to prevent oozing while maintaining ease of application through simple placement.
2Ease of operation
If a liquid or creamy denture adhesive is used, then ease of application is improved, but stability and retention decrease due to bio-erosion
Solution Approach 1:
The patent changes the physical state from liquid/cream to solid, which fundamentally alters the adhesive's resistance to bio-erosion. The solid form maintains structural integrity and stability while remaining easy to apply.
Solution Approach 2:
The solid denture adhesive is designed as a single-use article that is discarded after one application, eliminating the problem of progressive bio-erosion that affects reusable liquid adhesives.
3Reliability
If more denture adhesive is applied, then denture retention is improved, but oozing and negative aesthetics increase
Solution Approach 1:
The solid form of the denture adhesive provides sufficient retention with minimal application amount. The structural integrity of the solid material prevents oozing even when applied in adequate quantities for retention.
4Ease of operation
If a water-soluble denture adhesive is used, then ease of removal is improved, but oozing and negative mouth-feel increase
Solution Approach 1:
The patent changes the adhesive from water-soluble liquid/cream to water-insoluble solid. This allows the adhesive to be easily removed as a single piece while preventing oozing and negative mouth-feel associated with water-soluble formulations.
