Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intraoral image processing methods struggle to make the gingival region appear natural when expanded from three-dimensional scan data, often resulting in angled edges that disrupt the natural shape.
Innovation Solution
An intraoral image processing method and device that acquire three-dimensional intraoral data, identify a tooth region, and determine a gingival region with an edge formed by a curve having smaller curvature than the tooth region's edge, allowing for a smooth expansion and natural appearance of the gingival region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the gingival region is expanded from three-dimensional scan data, then the visual appearance is improved, but the edge becomes angled and unnatural
Solution Approach 1:
The patent applies curvature principles by generating a curve with smaller curvature than the original tooth region edge. This curve is used to define the gingival region boundary, ensuring that when the region is expanded, the edge maintains a smooth, natural appearance rather than forming sharp angles. The curvature constraint is mathematically enforced to preserve aesthetic quality.
2Measurement precision
If the edge of the gingival region is formed with high curvature, then the region can be clearly defined, but the expanded edge looks angled and unnatural
Solution Approach 1:
The patent changes the curvature parameter of the boundary curve. Specifically, it requires that the curve forming the gingival region edge has smaller curvature than the original tooth region edge. This parameter modification ensures that the boundary is sufficiently defined while maintaining smoothness for natural appearance after expansion.
3Productivity
If automatic region selection is used, then processing efficiency is improved, but control over the exact curvature characteristics is lost
Solution Approach 1:
The system performs automatic region selection where the algorithm autonomously identifies the tooth region and generates the gingival region boundary based on predefined curvature constraints. The process self-adjusts to ensure the curve has appropriate curvature characteristics without requiring manual intervention, thus maintaining both efficiency and precision.
