Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective prediction tools for the development of dental conditions such as tooth wear and gingiva recession over time, making it difficult for dentists to inform patients about potential future issues and recommend timely preventive measures.
Innovation Solution
A method using digital 3D representations of teeth obtained at different points in time to derive a formula expressing the development of dental conditions as a function of time, allowing for the prediction of future changes and the identification of critical thresholds, thereby enabling informed decision-making on preventive actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital 3D representations are obtained at multiple time points to predict dental condition development, then prediction accuracy is improved, but time consumption and measurement complexity increase
Solution Approach 1:
The system performs preliminary actions by obtaining digital 3D representations at multiple time points before the dental condition reaches a critical state. This allows the prediction model to be trained in advance with historical data, enabling accurate forecasting of future development without requiring extensive time when actual treatment becomes urgent.
Solution Approach 2:
The system creates digital 3D copies (virtual models) of the patient's teeth at different time points. These digital copies serve as data inputs for the prediction algorithm, allowing multiple measurements and analyses without requiring repeated physical interventions or delaying treatment decisions.
2Measurement precision
If digital 3D representations are obtained at multiple time points to predict dental condition development, then prediction accuracy is improved, but the complexity of the diagnostic process increases
Solution Approach 1:
The digital 3D scanning system serves multiple functions: it captures geometric data, tracks changes over time, and provides input for prediction algorithms. This multi-functional approach consolidates what would otherwise require separate diagnostic procedures into a single comprehensive tool, reducing overall diagnostic complexity while maintaining high prediction accuracy.
Solution Approach 2:
The digital 3D representation acts as an intermediary between the physical dental condition and the prediction algorithm. By converting complex physical measurements into standardized digital models, the system simplifies the interface between data collection and analysis, making the diagnostic process more manageable despite the multiple time points involved.
3Reliability
If digital 3D representations are obtained at multiple time points to predict dental condition development, then future development can be predicted, but the quantity of data to be processed increases
Solution Approach 1:
The system extracts only the relevant features and parameters from the complete digital 3D representations that are necessary for predicting dental condition development. By identifying and isolating the critical change indicators (such as enamel thickness, gingival margin position), the system reduces the data volume while preserving the information needed for reliable predictions.
Solution Approach 2:
The diagnostic process is segmented into distinct stages: data collection at multiple time points, feature extraction from 3D models, and prediction analysis. This segmentation allows the system to process large volumes of raw 3D data by breaking it down into manageable components, reducing the overall data processing burden while maintaining prediction reliability.
