Split Denture Base and Teeth Design for Faster Custom Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dentures require complex, time-consuming, and expensive adjustments to meet individual patient requirements for fit, occlusion, phonetics, and aesthetics, often necessitating multiple dental visits.
Innovation Solution
A split denture method involving a base part made of harder material for a tight fit and a teeth part made of softer material for adjustments, allowing independent manufacturing and testing of different tooth designs without replacing the entire denture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a complete denture is manufactured as a single unit, then the structure is simple and manufacturing is straightforward, but adjustments to meet individual patient requirements are complex, time-consuming and expensive
Solution Approach 1:
The denture is divided into two separable parts: a base part and a teeth part. The base part includes the artificial gingiva and supporting structures, while the teeth part contains the artificial teeth and can be detached for adjustments. This segmentation allows the base part to be manufactured once and reused, while only the teeth part needs adjustment, significantly reducing the time and complexity of modifications required to meet individual patient requirements.
2Adaptability or versatility
If the entire denture is replaced to test different tooth designs, then the new design can be fully evaluated, but production time and material waste increase
Solution Approach 1:
By separating the teeth part from the base part, the invention enables selective replacement of only the teeth part to test different designs. The base part remains intact and can be reused across multiple denture versions. This reduces production time and material waste compared to manufacturing entirely new dentures for each design iteration.
Solution Approach 2:
The teeth part can be created as a removable component that can be copied or replicated with different designs while using the same base part. This allows multiple design variations to be tested without manufacturing complete new dentures, improving productivity and reducing material consumption.
3Ease of repair
If softer material is used for the entire denture, then adjustments are easier to perform, but the fit and stability are reduced
Solution Approach 1:
Different parts of the denture are made from materials with different properties. The base part is constructed from harder material to provide stable fit and support, while the teeth part is made from softer material to facilitate easy adjustments. This local differentiation of material properties allows each component to optimize its function: stability for the base and adjustability for the teeth.

AI summary
The invention relates to a method for configurating a split denture. A digital 3D model of the denture comprising a plurality of teeth is provided. The digital 3D model of the denture is split into a digital 3D model of a base part and a digital 3D model of a teeth part. The base part comprises a first artificial gingiva portion. Further, the base part is configured to support the teeth part. The teeth part comprises the plurality of teeth of the denture and a second gingiva portion. The teeth part is configured to be mounted on the base part. The digital 3D model of the split denture is provided for generating at least one of the base part and the teeth part.
