Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing denture design methods fail to adequately account for the dynamic movements of a patient's jaw, leading to poorly fitting and uncomfortable dentures.
Innovation Solution
A motion-based denture design system that captures patient jaw motion data using a motion capture system, which is then used to generate a digital model for designing dentures that fit better and provide balanced occlusal support during functional movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional static denture design methods are used, then the design process is simple and quick, but the dentures do not account for dynamic jaw movements leading to poor fit and comfort
Solution Approach 1:
The system performs preliminary capture and analysis of patient jaw motion data before denture design, creating a motion model that guides the design process. This preliminary action ensures the denture accounts for dynamic movements from the outset, resolving the contradiction by preparing necessary information in advance rather than during fitting adjustments
Solution Approach 2:
The system creates a digital copy of the patient's jaw motion through motion capture technology, generating a virtual model that can be analyzed and used for design without requiring physical prototypes or repeated trial fittings. This digital copying approach maintains precision while managing complexity through virtual simulation
2Manufacturing precision
If motion capture technology is implemented to capture jaw motion data, then denture fit and comfort are improved, but the number of visits and chair time are reduced
Solution Approach 1:
The system replaces traditional mechanical trial-and-error fitting methods with a digital motion-based design system. By substituting physical adjustments with computational modeling based on captured motion data, the system achieves precise fit in fewer visits, reducing chair time while maintaining or improving precision
Solution Approach 2:
The system enables the design process to be more self-contained and efficient by capturing all necessary jaw motion data during a single visit and using that data to generate the complete denture design. This reduces the need for multiple adjustment visits, as the system performs the analytical work that would otherwise require repeated patient appointments
3Manufacturing precision
If multiple visits are scheduled for denture fitting adjustments, then precision can be improved through iterations, but patient time and clinic resources are consumed
Solution Approach 1:
The system performs preliminary capture and analysis of patient jaw motion data before denture design, creating a motion model that guides the design process. This preliminary action ensures the denture accounts for dynamic movements from the outset, resolving the contradiction by preparing necessary information in advance rather than during fitting adjustments
Solution Approach 2:
The system uses captured jaw motion data as feedback to optimize the denture design digitally before fabrication. By incorporating real motion data into the design process, the system achieves precise occlusion in the initial design, eliminating the need for multiple adjustment visits and improving clinic efficiency
