Dynamic 3D Occlusogram for Dental Malocclusion Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental treatment methods, such as conventional braces and Invisalign, face challenges in accurately calculating and displaying occlusal data, which is crucial for determining optimal tooth positioning and simulating tooth movement, especially in complex malocclusions, often relying on 2D representations that fail to accurately depict the extent and type of occlusal state.
Innovation Solution
The development of a method to calculate and display occlusal information using 3D models, including the creation of occlusograms, which involve determining potential occlusion tooth lists, calculating occlusal distances, and building height maps and distance fields to model the occlusal relationship between upper and lower teeth, allowing for a dynamic and real-time representation of tooth movement and bite adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If 2D representations are used to display occlusal data, then the device complexity is reduced, but the measurement precision and accuracy of occlusal state depiction deteriorates
Solution Approach 1:
The patent transitions from 2D occlusal representations to 3D occlusal models and height maps. By adding the third dimension (vertical height information), the system achieves accurate depiction of occlusal contacts, tooth positioning, and bite relationships while maintaining manageable system complexity through software-based rendering.
2Measurement precision
If detailed 3D occlusal modeling is implemented, then the measurement precision of tooth interactions is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The patent creates virtual 3D copies of patient-specific occlusal surfaces through height maps and digital models. These digital replicas enable precise measurement and simulation of tooth interactions without requiring complex physical measurement devices, reducing hardware complexity while maintaining high measurement precision.
Solution Approach 2:
The patent replaces complex mechanical measurement systems with computational methods. By using algorithms to generate height maps and 3D models from scanned data, the system achieves detailed occlusal analysis through software processing rather than mechanical measurement apparatus.
3Device complexity
If static occlusal models are used, then the device complexity is minimized, but the adaptability to simulate dynamic tooth movement deteriorates
Solution Approach 1:
The patent implements dynamic 3D occlusal models that can be updated in real-time as teeth move during treatment. The height map technology allows the virtual occlusal surfaces to be regenerated and updated to reflect changing tooth positions, enabling simulation of treatment progression while maintaining relatively simple system architecture.
