Digital Denture Base Real-Time Arch Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for designing digital dentures require manual adjustments and subsequent grinding to correct arch changes and tooth spacing, leading to issues like overjet, tooth interferences, and malocclusion, which can result in additional rework and enamel reduction.
Innovation Solution
A method and system for automatically adapting the arches and tooth anatomy in real-time using computer software to maintain anatomical relationships between teeth, correcting interferences and malocclusions, and eliminating the need for subsequent grinding by auto-sizing and morphing teeth in response to changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustments are made to correct arch changes and tooth spacing, then anatomical relationships can be maintained, but additional grinding and rework are required
Solution Approach 1:
The software performs preliminary automated adjustments to tooth position and arch form during the digital design phase, anticipating and correcting potential occlusion issues before manufacturing. This preliminary action eliminates the need for subsequent manual grinding and rework by ensuring proper anatomical relationships are established in the digital model itself.
2Adaptability or versatility
If tooth size or position is changed, then customization is improved, but arch length and tooth spacing are adversely impacted
Solution Approach 1:
The software implements real-time feedback mechanisms that automatically monitor and adjust arch length and tooth spacing when tooth size or position is modified. This closed-loop system ensures that customization changes maintain proper anatomical relationships by continuously evaluating and correcting spacing issues as they arise during the design process.
Solution Approach 2:
The digital design system dynamically adapts arch form and tooth positioning in response to customization changes. Rather than static designs, the software allows continuous adjustment and re-evaluation of spatial relationships, enabling customized tooth configurations while automatically maintaining proper arch length and spacing through real-time computational geometry.
3Manufacturing precision
If arches are modified to correct malocclusion, then occlusion is improved, but tooth interferences are created
Solution Approach 1:
The software applies preliminary anti-action by automatically detecting and preventing tooth interferences before they become problematic. When arch modifications are made to correct malocclusion, the system proactively identifies potential interference zones and adjusts tooth positioning in advance to eliminate these harmful effects, rather than allowing interferences to develop and then requiring corrective grinding.
