Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assessing dental situations lack precision and real-time analysis capabilities, impacting the quality of dental treatments and patient compliance, particularly in individualized orthodontic treatments.
Innovation Solution
A method involving the acquisition of a real dental scene through a camera, generation of a virtual dental scene based on the real scene, and overlaying it transparently on the real scene for simultaneous comparison and simulation, enhancing the analysis and simulation of dental treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional dental assessment methods are used, then the process is simple and quick, but the precision and real-time analysis capabilities are insufficient
Solution Approach 1:
The patent creates a virtual dental scene that is a digital copy of the real dental scene, allowing precise comparison and analysis. The virtual model replicates tooth positions, orthodontic appliance locations, and other dental features to enable accurate measurement and assessment without requiring complex physical measurement tools.
Solution Approach 2:
The patent introduces a camera and image processing system as an intermediary between the dental professional and the actual dental scene. This intermediary captures images, generates virtual scenes, and overlays them with real-time feedback, providing precise analysis capabilities while keeping the interface simple for the dental professional.
2Speed
If traditional dental assessment methods are used, then the equipment is simple, but real-time analysis and immediate feedback are not available
Solution Approach 1:
The patent implements continuous image capture and processing, where the camera continuously acquires images of the dental scene and the system continuously generates and updates the virtual dental scene. This continuous process enables real-time analysis and immediate feedback without interrupting the dental procedure.
Solution Approach 2:
The patent replaces traditional mechanical measurement and assessment methods with optical (camera-based) and computational (image processing) approaches. This substitution enables faster, real-time analysis while reducing the mechanical complexity of physical measurement tools.
3Reliability
If virtual dental scene overlay is implemented, then treatment quality and patient compliance improve, but the device complexity and processing requirements increase
Solution Approach 1:
The patent merges the virtual dental scene with the real dental scene by overlaying the virtual image onto the camera's real-time view. This combination allows dental professionals to see both the actual dental structures and the virtual representation simultaneously, improving treatment accuracy and patient understanding without requiring separate viewing systems.
Solution Approach 2:
The patent uses color and transparency variations in the overlay to differentiate between real and virtual elements. The virtual dental scene is displayed with adjustable transparency and color coding to highlight specific features such as tooth positions, appliance locations, and treatment progress, making the information easily distinguishable and interpretable.

AI summary
A method for analyzing a real dental situation of a patient. The method includes steps, as follows, in succession. At an updated instant, acquisition of an updated image representing a real dental scene as observed by an operator. Simulation, for a simulation instant, of the real dental scene represented on the updated image, then determination of a virtual dental scene as a function of the simulation. Presentation of the virtual dental scene in transparent mode and overlaid on the real dental scene, or display of the updated image on a screen and presentation of the virtual dental scene overlaid with the representation of the real dental scene on the updated image displayed on the screen, in transparent mode or not on the representation.
