3D Dental Model Rendering With Interactive Region Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for comparing digital dental models are inadequate for visualizing changes in dental conditions, relying heavily on user interpretation and lacking technical means for guided, region-specific assessment, especially when changes are subtle.
Innovation Solution
A method and system for rendering digital dental models by superimposing them in a 3D space, allowing a 2D controller to demarcate zones for selective rendering of different dental models, enabling controlled user interaction for precise region-specific assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital dental models are presented side-by-side in a static manner, then the user can visualize both models simultaneously, but the user cannot establish correspondences between specific regions across the models and relies heavily on mental determination which is subjective
Solution Approach 1:
The patent introduces a 2D controller as an intermediary tool between the user and the superimposed 3D dental models. This controller enables objective, guided interaction by allowing the user to selectively render different models in specific zones, thereby establishing precise region-specific correspondences without relying solely on mental determination.
Solution Approach 2:
The patent divides the superimposed dental models into different zones (first zone and second zone) that can be selectively rendered. This segmentation allows the user to focus on specific regions of interest, enabling precise region-specific assessment while maintaining the ability to visualize both models simultaneously.
2Adaptability or versatility
If digital dental models are arranged in a sequence along a timeline, then the user can toggle between models, but the user cannot easily establish correspondences between specific regions and must mentally track correspondences which is subjective
Solution Approach 1:
The patent transforms the static side-by-side or sequential model presentation into a dynamic superimposed view where the user can interactively control the rendering of different models in different zones. This dynamic interaction enables precise region-specific assessment while maintaining navigation flexibility through the 2D controller.
3Device complexity
If conventional methods are used for comparing digital dental models, then the system is simple to implement, but the evaluation is subjective and lacks technical means for guided region-specific assessment
Solution Approach 1:
The 2D controller serves as an intermediary that introduces objective, guided interaction capability to the system. It provides technical means for region-specific assessment while maintaining relative system simplicity by building upon existing 3D modeling and rendering capabilities rather than requiring entirely new hardware or complex processing systems.
4Device complexity
If the user is expected to mentally determine correspondences between models, then no additional technical means are required, but the assessment becomes subjective and cannot reliably detect subtle changes
Solution Approach 1:
The 2D controller acts as an intermediary tool that assists the user in objectively identifying and comparing specific regions across models. This eliminates the need for purely mental determination and provides technical support for detecting subtle changes with precision, while adding minimal complexity to the overall system.

AI summary
A computer implemented method for rendering digital three-dimensional dental models includes receiving a first digital 3D dental model including a first dental information of a patient; receiving a second digital 3D dental model including a second dental information of the patient; generating, in the digital 3D space, 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 a 2D controller and the superimposed model relative to each other such that a position of the 2D controller defines a boundary that demarcates the superimposed model between a first zone and a second zone.
