Denture Base Socket Groove Structure for Stronger Tooth Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dentures produced by resin cast or 3D printing methods are prone to breaking due to insufficient strength, and reinforcing materials like metal or glass fibers complicate the manufacturing process and affect aesthetics.
Innovation Solution
A denture base design with continuous grooves between sockets allows for seamless adhesive application, enhancing the structural integrity of the denture by ensuring the adhesive is continuously disposed over multiple sockets, thereby improving the adhesion strength without using visible reinforcing materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcing materials like metal or glass fibers are embedded into the denture base, then the strength of the denture is improved, but the manufacturing process becomes more complex and aesthetics are affected
Solution Approach 1:
The patent removes the need for separate reinforcing materials (metal wires, glass fibers) by extracting the reinforcement function from discrete components and integrating it into the continuous adhesive structure itself. The adhesive layer becomes the reinforcing element through its continuous configuration and bonding to multiple sockets simultaneously.
Solution Approach 2:
The patent merges the functions of adhesion and reinforcement into a single continuous adhesive layer. This layer both bonds artificial teeth to the denture base and provides structural reinforcement, eliminating the need for separate reinforcing materials and simplifying the manufacturing process.
2Strength
If reinforcing materials are embedded into the denture base, then the strength of the denture is improved, but the aesthetic appearance is compromised due to visible reinforcing materials
Solution Approach 1:
The continuous adhesive layer provides localized reinforcement at critical stress points where artificial teeth are positioned, rather than using bulk reinforcing materials throughout. This targeted approach maintains aesthetic appearance while providing necessary strength enhancement.
Solution Approach 2:
The continuous adhesive layer creates a homogeneous structure that integrates seamlessly with the denture base and artificial teeth. This uniform appearance eliminates visible boundaries or textures associated with separate reinforcing materials, preserving aesthetic quality.
3Productivity
If traditional resin cast or 3D printing methods are used to manufacture dentures, then manufacturing efficiency is improved, but the dentures are prone to breaking due to insufficient strength
Solution Approach 1:
The continuous adhesive layer is prepared and positioned in advance during the manufacturing process, creating pre-bonded connections between sockets before final assembly. This preliminary action ensures that the denture structure is pre-strengthened against breaking during use.
Solution Approach 2:
The patent creates a composite structure combining the denture base material, continuous adhesive layer, and artificial teeth into an integrated assembly. This composite construction provides enhanced durability while maintaining the manufacturing efficiency of modern resin cast and 3D printing methods.
