Motion-Based Denture Design System
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 fit well and cause discomfort due to ignoring dynamic jaw movements
Solution Approach 1:
The system performs preliminary capture of patient jaw motion data before denture design, storing this dynamic information for later use. This preliminary action allows the denture to be designed with pre-calculated clearance zones that prevent interference during jaw movement, improving fit precision without adding complexity to the actual design process.
Solution Approach 2:
The system creates a digital copy or model of the patient's jaw motion patterns, allowing virtual simulation and analysis of denture-teeth interactions during movement. This digital copying enables precise adjustment of denture geometry based on actual motion data without requiring complex physical prototypes or trial-and-error fitting procedures.
2Reliability
If motion capture systems and digital modeling are implemented, then denture fit and comfort are improved, but the chair time and number of visits increase
Solution Approach 1:
The system replaces traditional mechanical trial-fitting procedures with digital modeling and simulation. By substituting physical adjustment iterations with computational analysis of jaw motion data, the system achieves reliable denture fit in fewer visits and reduced chair time, as digital modifications can be made instantly without remaking physical prototypes.
Solution Approach 2:
The system enables self-adjustment of denture design parameters based on captured motion data, reducing the need for multiple provider visits. The digital model can automatically optimize clearance zones and tooth positioning based on the patient's own jaw movement patterns, minimizing manual intervention and extending the time between fitting visits.
3Productivity
If dentures are designed without considering dynamic jaw movements, then the design process is faster, but the dentures interfere with opposing teeth during bite motion
Solution Approach 1:
The system performs preliminary capture and analysis of jaw motion data before finalizing the denture design. By pre-calculating the clearance zones needed to prevent tooth interference based on actual patient movement patterns, the design can be completed faster without causing harmful interactions during biting, as the interference prevention is built into the initial design rather than requiring later adjustments.
