Dental Component Construction via 3D Volume Surface Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing tooth replacement parts require users to navigate within CT or optical surface data to find relevant regions, making the process complex and difficult.
Innovation Solution
A method that correlates a 3D volume model of a dental condition with a 3D surface model, restricting the graphic representation to relevant regions using the surface model or its sections, thereby hiding irrelevant areas, allowing for clear construction and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the complete 3D volume model is displayed for construction planning, then all relevant anatomical information is available, but the complexity of navigation and visualization increases significantly
Solution Approach 1:
The patent segments the 3D volume model data into multiple 2D graphic representations showing different anatomical structures (teeth, jawbone, nerves, blood vessels) as separate layers. Users can selectively view and navigate through these segmented layers rather than navigating a single complex 3D volume, thereby reducing navigation complexity while preserving access to all anatomical information.
Solution Approach 2:
The patent transforms the 3D volume model into multiple 2D cross-sectional graphic representations. This dimensionality reduction simplifies the visualization and navigation interface while maintaining comprehensive anatomical information through stacked 2D slices that can be viewed in sequence or combination.
2Loss of information
If the complete 3D volume model is displayed, then comprehensive anatomical data is visible, but the clarity of relevant regions decreases due to information overload
Solution Approach 1:
The patent separates different anatomical structures into distinct 2D graphic layers (teeth, jawbone, nerves, blood vessels). This segmentation allows users to focus on specific structures of interest without being distracted by irrelevant anatomical data, improving region identification ease while preserving complete anatomical information across all layers.
Solution Approach 2:
The patent enables users to selectively activate and view specific anatomical structures in each 2D graphic representation based on the specific construction task. For example, when planning an implant, users can focus on jawbone density and nerve locations while temporarily hiding less relevant structures, thereby improving clarity without losing access to comprehensive anatomical data.
3Loss of information
If all anatomical structures are visualized in the 3D model, then complete diagnostic information is available, but the time required to locate relevant regions increases
Solution Approach 1:
The patent organizes complete diagnostic information into segmented 2D graphic layers representing different anatomical structures. Users can quickly navigate to relevant diagnostic information by selecting specific layers rather than searching through a unified 3D volume, significantly reducing navigation time while preserving all diagnostic data.
Solution Approach 2:
The patent pre-processes the 3D volume model into multiple organized 2D graphic representations with different anatomical structures separated into distinct layers before the user begins construction planning. This preliminary segmentation allows users to immediately access relevant diagnostic information without performing time-consuming navigation or data processing during the planning phase.

AI summary
The invention relates to a method for constructing a dental component (I) using a graphic representation of a dental condition. A 3D volume model of the dental condition is thus already correlated with a 3D surface model of the dental condition, wherein the graphic representation of the 3D volume model is restricted to relevant regions by delimitation using the 3D surface model or using a section thereof, wherein the remaining regions of the 3D volume model are hidden.
