Digital Dental Impression Stroke Completion Trigger Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental procedure planning systems face challenges in efficiently processing and editing 3D digital dental impressions, particularly with touch-based interfaces, where real-time computation of visual elements is resource-intensive and less precise compared to traditional input devices, leading to slower processing and reduced user interaction.
Innovation Solution
A computer-implemented method using trigger logic to detect stroke completion in digital dental impression editing, allowing for faster processing by executing algorithms only when necessary, enabling faster frame rates and reducing processing requirements through techniques like fill hole and erase island algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If real-time computation of visual elements is performed during digital dental impression editing, then user interaction responsiveness is improved, but processing speed deteriorates due to resource-intensive computation
Solution Approach 1:
The system performs computation-intensive processing not continuously but periodically triggered by specific user actions (stroke completion, tool selection changes). This allows the system to maintain real-time responsiveness for basic interactions while executing heavy computations only when necessary, resolving the contradiction between user interaction responsiveness and processing speed.
Solution Approach 2:
The system pre-calculates and caches certain visual elements and processing results before they are actually needed. When users interact with the interface, pre-computed data is readily available, providing responsive user experience without requiring real-time computation for every display update.
2Ease of operation
If continuous processing of visual elements is performed, then user interaction responsiveness is improved, but processing requirements increase
Solution Approach 1:
Instead of continuous processing, the system uses periodic processing triggered by specific events (stroke completion, tool changes). This dramatically reduces overall processing requirements and energy consumption while maintaining responsiveness for critical user interactions.
Solution Approach 2:
The system extracts and separates computation-intensive operations from the main processing loop. By identifying and isolating specific processing tasks that can be deferred or pre-computed, the system reduces ongoing processing requirements while maintaining user interaction responsiveness.
3Ease of operation
If touch-based interface is used for dental procedure planning, then portability and convenience are improved, but adjustment precision deteriorates compared to traditional input devices
Solution Approach 1:
The system automatically performs certain adjustments and corrections that would otherwise require precise manual input. By detecting stroke completion and automatically finalizing adjustments, the system compensates for the lower precision of touch-based input while maintaining the portability and convenience benefits.
Solution Approach 2:
The system provides visual feedback and confirmation during the editing process, allowing users to review and confirm adjustments before finalizing them. This feedback mechanism helps compensate for reduced input precision by enabling users to verify and correct adjustments visually.

AI summary
The disclosure relates to a method for processing a digital dental impression including: displaying an image of the digital dental impression; the image including: a shaded region representative of a part of the oral anatomy which is relevant for a dental procedure, and the shaded region being enclosed within a boundary; and an unshaded region representative of a part of the oral anatomy which is not relevant for a dental procedure. The unshaded region and the shaded region are separated from each another by the boundary. The method includes; receiving user input for altering the shaded region and/or unshaded region; detecting completion of a stroke generated by the user input; altering, the shaded region and/or the unshaded region, in response to the stroke completion. The present teachings also relate to a method for processing digital three-dimensional shapes, a dental procedure assisting system, uses and computer software products.
