Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic treatment evaluation methods face challenges in systematically and objectively comparing planned treatment performance to real treatment performance due to factors like patient-specific conditions, treatment complexity, and the lack of standardized digital data collection, leading to inefficiencies in evaluating treatment performance.
Innovation Solution
A computer-implemented system and method using 3D virtual dental models to automatically determine orthodontic treatment plan and performance scores by obtaining, processing, and applying index classifiers to virtual stage and dental mesh models, eliminating manual measurements and physical materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurements and physical materials are used for orthodontic treatment evaluation, then treatment performance can be assessed, but the evaluation process is time-consuming, less precise, and less accurate
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated computer-implemented system that processes 3D virtual dental models. The system automatically extracts geometric parameters, applies index classifiers, and generates treatment performance scores without requiring manual measurement tools or physical model handling, thereby improving both precision and reducing evaluation time.
Solution Approach 2:
The patent uses 3D virtual dental models (digital copies) of patient dentition instead of physical models. These virtual models can be obtained through intraoral scanning or by digitizing physical models, allowing for repeated, precise measurements without wear or degradation, and enabling automated processing while maintaining measurement accuracy.
2Productivity
If standardized digital evaluation methods are implemented, then evaluation accuracy and efficiency improve, but system complexity increases
Solution Approach 1:
The patent segments the evaluation process into distinct automated modules: (1) obtaining 3D virtual dental models, (2) extracting geometric parameters automatically, (3) applying index classifiers to generate scores, and (4) comparing planned versus real treatment performance. This segmentation allows each module to be independently optimized and processed automatically, improving efficiency while managing system complexity through modular design.
3Measurement precision
If automated virtual model processing is used, then measurement accuracy and evaluation speed improve, but the complexity of data processing increases
Solution Approach 1:
The patent implements automated self-service functionality where the software system automatically performs parameter extraction, measurement calculations, and score generation from 3D virtual dental models without requiring manual intervention. The system includes built-in algorithms that autonomously process the geometric data, apply appropriate index classifiers, and generate treatment performance evaluations, thereby maintaining high precision while reducing the operational complexity burden on users.
