3D Tooth Model Planning With Root-Aware Orthodontic Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orthodontic programs fail to accurately establish orthodontic planning due to the lack of consideration of the root area of teeth, leading to inadequate control of tooth movement during orthodontic treatment, which can result in insufficient blood flow and potential tooth movement cessation.
Innovation Solution
A method and computing device that generate a 3D tooth model incorporating both crown and root areas, allowing for precise control of tooth movement by calculating the expected movement of the root and adjusting the orthodontic planning to maintain optimal periodontal ligament thickness and movement within allowable ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If orthodontic planning is established using only crown area of teeth, then the planning process is simplified, but the accuracy of orthodontic planning deteriorates
Solution Approach 1:
The tooth model is segmented into two distinct parts: crown area and root area. The system separately processes and analyzes each region, allowing independent evaluation of orthodontic movements on both crown and root, thereby improving overall planning accuracy without significantly complicating the workflow
Solution Approach 2:
The system transitions from two-dimensional crown-only analysis to three-dimensional comprehensive analysis by incorporating root area data. This dimensional expansion enables accurate determination of axis and center of rotation in 3D space, resolving the accuracy issue while maintaining computational efficiency
2Device complexity
If root area is excluded from 3D tooth model, then modeling complexity is reduced, but the reliability of orthodontic treatment planning deteriorates
Solution Approach 1:
The 3D tooth model is divided into crown and root segments that can be independently processed and analyzed. This segmentation allows the system to handle complex root morphology separately from the crown, improving reliability of treatment planning while managing computational complexity through modular processing
Solution Approach 2:
The system performs preliminary analysis of the root area to automatically determine the axis and center of rotation before final orthodontic planning. This preliminary action on the root structure provides accurate reference points that enhance treatment planning reliability without requiring manual intervention
