Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental prosthesis bases lack a realistic reproduction of blood vessels, limiting their natural appearance.
Innovation Solution
A method for determining the internal structure of a dental prosthesis base with blood vessel replicas using CAD/CAM software, combining outer shell data with blood vessel data to create a detailed, lifelike internal structure through Boolean operations, additive manufacturing, and varying material properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If fibrous material is added to replicate blood vessels, then the visual realism of the denture base is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent uses optical copying by capturing an image of a natural tongue (which contains blood vessels) and transferring this visual pattern onto the denture base. This creates a realistic blood vessel appearance without the complexity of physically replicating actual blood vessels through fibrous materials or injection molding
Solution Approach 2:
The patent changes the approach from physical replication (fibrous materials, injection molding) to optical/visual replication through image processing. By transforming the problem from three-dimensional physical structure to two-dimensional visual pattern, the manufacturing complexity is significantly reduced while maintaining visual realism
2Shape
If the outer shell is made translucent or transparent, then the natural appearance is improved, but the internal structure becomes more visible and requires more complex replication
Solution Approach 1:
Instead of physically replicating complex internal blood vessel structures that would be visible through the translucent shell, the patent uses optical copying by projecting an image of natural blood vessels onto the inner surface or incorporating it into the material. This creates the illusion of internal structure without the manufacturing complexity of actual physical replication
3Manufacturing precision
If detailed internal structure with blood vessels is created, then the fidelity of the denture base is improved, but the manufacturing time and complexity increase
Solution Approach 1:
The patent achieves high-fidelity blood vessel replication by copying an image from a natural tongue photograph through digital image processing. This 2D copying method produces realistic blood vessel patterns without requiring time-consuming 3D modeling, sculpting, or multi-step molding processes
Solution Approach 2:
The patent replaces mechanical manufacturing methods (such as injection molding with fibrous materials or hand-sculpting) with an optical/digital approach. By using image capture and processing instead of mechanical replication, both fidelity and manufacturing efficiency are improved
