Current methods for producing artificial dentures, particularly the base part, are inefficient in achieving a precise fit and customizable coloration, and often require multiple steps and materials, which can lead to suboptimal fit and aesthetic results.
Innovation Solution
A computer-aided manufacturing method using rapid prototyping techniques, such as 3D laser lithography, to create the base part and teeth, allowing for precise scanning and modeling of the gum area, enabling the production of gum-colored and tooth-colored components with integrated fastening mechanisms, and the option to recolor or add wear-resistant layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional multi-step manufacturing methods are used for base parts and teeth, then production flexibility and material selection are improved, but manufacturing complexity and production time increase
Solution Approach 1:
The patent combines the manufacturing of base parts and teeth into a single integrated rapid prototyping process. The base part and teeth are produced as one piece using 3D laser lithography, eliminating the need for separate manufacturing steps and reducing overall manufacturing complexity while maintaining material selection flexibility.
Solution Approach 2:
The rapid prototyping process serves multiple functions simultaneously: it creates the base part structure, forms the teeth, and applies coloration in a single manufacturing operation. This multi-functional approach reduces the number of separate processes needed while maintaining design flexibility.
2Productivity
If traditional manufacturing methods are used, then production time for multiple components is reduced, but manufacturing precision and fit accuracy deteriorate
Solution Approach 1:
By manufacturing the base part and teeth as a single integrated component using rapid prototyping, the patent eliminates assembly errors and ensures precise fit accuracy. The one-piece production process maintains manufacturing precision while the rapid prototyping technique keeps production time efficient.
3Ease of manufacture
If base part and teeth are produced separately, then manufacturing flexibility is improved, but fit precision and aesthetic results deteriorate
Solution Approach 1:
The patent merges the production of base part and teeth into a single rapid prototyping process, achieving both fit precision and manufacturing flexibility. The integrated approach allows for precise customization of the interface between base part and teeth while maintaining the flexibility to adjust design parameters during the manufacturing process.
4Adaptability or versatility
If multiple materials and steps are used for coloration, then color customization is improved, but manufacturing complexity and time increase
Solution Approach 1:
The patent combines coloration with the base manufacturing process itself. The rapid prototyping system can incorporate color information directly into the manufacturing process, applying gum-colored and tooth-colored regions in the same operation that creates the structural components, thereby reducing production time while maintaining color customization capabilities.
