3D Dental Model Alignment for Lesion Comparison and Annotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for presenting and interacting with digital 3D models of dental conditions lack flexibility and often obscure annotations, making it difficult to track changes in dental conditions over time, and existing annotations are not well-suited for the 3D space.
Innovation Solution
A method for superimposing and aligning digital 3D models to display lesions with interactive windows, using a user-adjustable controller to divide the view into regions for each model, and placing annotations outside the lesion area to maintain visibility, with neural networks for lesion detection and re-training based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital 3D models are rotated or interacted with, then the user can inspect different angles of the model, but the annotations describing lesions may be hidden or misplaced
Solution Approach 1:
The display is divided into multiple regions: a first region showing a first digital 3D model and a second region showing a second digital 3D model. Annotations are placed in specific regions associated with their respective models, allowing users to interact with one model while annotations remain visible in their designated regions.
Solution Approach 2:
The patent transitions from a single-view 2D display to a multi-region 3D spatial arrangement of annotations. Annotations are positioned in specific spatial regions corresponding to their associated models, creating a dimensional separation that maintains visibility during model rotation and interaction.
2Quantity of substance
If side-by-side view or sequential view of digital 3D models is used, then multiple models can be displayed, but the user lacks flexibility to inspect changes without relying on individual skill
Solution Approach 1:
The display is segmented into multiple regions, each dedicated to a specific digital 3D model. This segmentation allows simultaneous presentation of multiple models while maintaining clear spatial separation, enabling users to easily compare and inspect changes between models without requiring complex interaction skills.
3Loss of information
If annotations are placed on digital 3D models, then lesion information can be conveyed, but the annotations are not well-suited for the 3D space and are difficult to interact with
Solution Approach 1:
Annotations are segmented and assigned to specific regions corresponding to their associated digital 3D models. This regional assignment creates a structured relationship between annotations and models, making annotations more suitable for 3D space and enabling easier interaction by linking annotation functions to specific spatial regions.

AI summary
A computer-implemented method for evaluating digital 3D models of teeth is disclosed. The method includes receiving first and second digital 3D models and generating a superimposed digital 3D model by mutually aligning the first and second digital 3D models and displaying a part of the superimposed model including a lesion of a dental condition. The displaying includes arranging a user-adjustable controller to vertically divide the displayed part of the superimposed model into first and second regions, wherein in the first and second regions only a part of the first and second digital 3D models are rendered, respectively; identifying first and second end point points of the lesion in the first and second regions, respectively; and arranging first and second interactive windows with x coordinates less than, or equal to the x coordinates of the first and second end points, respectively.
