3D Dental Model Rendering With Zone-Based Comparison Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for comparing digital dental models are subjective and lack technical means for guided, region-specific assessment of dental condition development, making dental treatment planning sub-optimal, especially when changes are subtle.
Innovation Solution
A method for superimposing digital 3D dental models in a 3D space, allowing a 2D controller to demarcate zones for selective rendering of model parts, enabling user-controlled relative movement for precise region-specific assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital dental models are presented side-by-side in a static manner, then the user can visualize multiple models simultaneously, but the user cannot easily establish correspondences between specific regions across the models, making assessment subjective
Solution Approach 1:
The system segments the dental models into multiple zones using a 2D controller that divides the model into different regions. This allows the user to focus on specific zones for comparison, establishing clear correspondences between regions across different time points while maintaining overall model context.
Solution Approach 2:
The system introduces a temporal dimension by allowing users to toggle between different time points while maintaining spatial correspondence through the 2D controller zones. This multi-dimensional approach enables precise region-specific assessment across time without losing anatomical context.
2Measurement precision
If digital dental models are arranged in a sequence along a timeline, then the user can toggle between models, but the user must mentally track correspondences across models, making evaluation subjective
Solution Approach 1:
The system pre-establishes zone boundaries and correspondences using the 2D controller before the user performs assessment. This preliminary organization of spatial relationships eliminates the need for users to mentally track correspondences during evaluation, reducing cognitive burden and improving accuracy.
3Adaptability or versatility
If conventional comparison methods are used, then the system is simple to operate, but the system cannot provide guided, region-specific assessment, leading to sub-optimal treatment planning
Solution Approach 1:
The 2D controller serves as an intermediary tool that guides users through region-specific assessment without requiring complex manual manipulation. It automatically maintains zone boundaries and correspondences, providing structured assessment capability while keeping the interface intuitive and easy to operate.

AI summary
A computer implemented method for rendering digital three-dimensional dental models of a patient includes receiving a first digital 3D dental model; receiving a second digital 3D dental model; generating a superimposed model by superimposing one of the first digital 3D dental model or the second digital 3D dental model on another of the second digital 3D dental model or the first digital 3D dental model; and arranging, in the digital 3D space, a 2D controller and the superimposed model relative to each other such that a position of the 2D controller relative to a location of the superimposed model defines a boundary that demarcates the superimposed model between a first zone configured to render only at least a part of the first digital 3D dental model from the superimposed model and a second zone configured to render only part of the second digital 3D dental model from the superimposed model.
