3D Dental Model Island Grouping for Faster Condition Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying dental conditions on 3D dental models require manual inspection, which is cumbersome due to scattered and potentially out-of-view indications, making it difficult to efficiently assess and compare dental health over time.
Innovation Solution
A computer-implemented method that identifies and groups regions on a 3D dental model into islands based on dental conditions, using visual indicators and automatic navigation to focus on areas of interest, allowing for efficient inspection and comparison of dental conditions over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual inspection method is used to identify dental conditions on 3D dental model, then user can visually inspect the determined indications, but the inspection process becomes cumbersome and time-consuming due to scattered indications across multiple sections
Solution Approach 1:
The patent segments the 3D dental model into multiple viewports or sections, allowing the user to simultaneously view different areas of the model. This segmentation enables scattered dental condition indications to be distributed across multiple visible sections, eliminating the need for manual navigation and reducing inspection time while maintaining comprehensive coverage.
2Loss of information
If comprehensive 3D dental model is displayed to show all dental conditions, then all indications can be visible, but the model complexity increases making it difficult to identify critical areas
Solution Approach 1:
The patent applies local quality by enhancing or highlighting specific regions of the 3D dental model where dental conditions are detected. Instead of uniformly displaying the entire model, critical areas are emphasized through visual indicators such as color coding, magnification, or selective rendering, allowing users to quickly identify problematic regions without being overwhelmed by the complexity of the complete model.
3Measurement precision
If user manually navigates through 3D dental model to find all dental conditions, then thorough inspection is possible, but productivity decreases due to repetitive manual searching
Solution Approach 1:
The patent performs preliminary action by automatically detecting and marking dental conditions on the 3D model before user inspection. The system pre-processes the model to identify caries, periodontal diseases, and other conditions, then presents these pre-identified areas to the user through enhanced visual indicators. This eliminates the need for users to manually search through the entire model, maintaining thoroughness while dramatically improving inspection efficiency.

AI summary
A method for identifying islands of interest on a 3D dental model includes receiving at least a first dental 3D scan data, generating the 3D dental model based on the received 3D data. Method further includes identifying a plurality of regions on the 3D dental model, each region indicating presence of at least one dental condition. A severity factor value for each region is determined. The method further includes marking, on the 3D dental model, each region of the plurality of regions with a visual indicator, wherein the visual indicator is selected based on the determined severity factor value for said region. A plurality of islands is then obtained by grouping the plurality of regions on the 3D dental model (100, 300) such that each island includes neighboring regions indicating presence of the at least one dental condition. The 3D dental model is then displayed.
