Digital Dental Impression Cleanup for Clear Tooth and Gum Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital dental impressions often contain extraneous data that obscure views of teeth and gums, limiting the ability to view, diagnose, and manipulate the model effectively.
Innovation Solution
A computer-implemented method for detecting and removing extraneous material from digital dental impressions by identifying dental features, filtering them, digitally joining these features, and determining regions of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a digital dental impression is captured to create a digital model for CAD/CAM processing, then a digital representation of the patient's dentition is obtained, but extraneous data such as walls and extra material are included that obscure views of teeth and gums
Solution Approach 1:
The patent applies the extraction principle by automatically identifying and removing extraneous material (walls and extra material) from the digital dental impression while preserving the useful dental structures. The system distinguishes between anatomical features (teeth, gums) and non-anatomical elements, extracting only the relevant dental information for CAD/CAM processing.
Solution Approach 2:
The patent segments the digital dental impression into distinct components: anatomical structures (teeth, gums) and extraneous material (walls, extra material). This segmentation allows the system to selectively process different regions, removing harmful extraneous data while preserving useful dental information through automated detection and classification algorithms.
2Ease of operation
If extraneous material is removed from the digital dental impression, then clarity of teeth and gum regions is improved, but the complexity of detecting and removing the extraneous data increases
Solution Approach 1:
The patent implements self-service by enabling the digital dental impression processing system to automatically detect, classify, and remove extraneous material without requiring manual intervention. The system uses automated algorithms to identify anatomical versus non-anatomical structures, perform the removal operation, and generate the cleaned model independently, thereby improving ease of operation while managing complexity through automation.

AI summary
A computer-implemented method and system of automatically detecting and removing extraneous material from a digital dental impression includes detecting one or more dental features in a digital dental impression, filtering the one or more dental features, digitally joining the one or more dental features, and determining one or more regions of interest from the joined one or more digital dental features.
