3D Mark Point Recognition for Adaptive Mandibular Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mandibular movement tracking solutions face issues with poor adaptability due to fixed targets that do not fit well with the user's dental condition, leading to errors and reduced applicability, especially in cases like severe overbite.
Innovation Solution
Directly fix mark points to the maxilla and mandible based on the user's dental condition, acquiring and recognizing three-dimensional coordinates to distinguish first and second mark points, using algorithms like ICP or NICP for accurate tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed targets are used for mandibular movement tracking, then the tracking method is simple and standardized, but the adaptability to different dental conditions deteriorates
Solution Approach 1:
The patent transforms the static fixed targets into dynamic customizable mark point configurations. The system allows flexible positioning of mark points on the target based on individual dental conditions, enabling the target to adapt to different user requirements while maintaining the overall tracking functionality.
Solution Approach 2:
The patent applies local customization by allowing different regions of the target to have different mark point configurations. Users can select specific locations and numbers of mark points according to their dental conditions, such as placing mark points on teeth, gums, or other anatomical structures as needed.
2Device complexity
If fixed targets are used for mandibular movement tracking, then the device structure is simple, but the measurement precision deteriorates due to poor fit
Solution Approach 1:
The patent performs preliminary configuration of mark points on the target before actual tracking. Users pre-select and position mark points according to their dental conditions, ensuring optimal placement for accurate tracking. This preliminary action prevents tracking errors caused by poor fit during the actual measurement process.
Solution Approach 2:
The system incorporates feedback mechanisms to verify mark point placement and ensure accurate tracking. By allowing users to adjust mark point positions and configuring them based on individual dental anatomy, the system continuously optimizes tracking precision while maintaining device simplicity.
