Virtual Camera Optimization for Alternative Incisal Dental Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional views of three-dimensional dental models often occlude important dental features, making it difficult for orthodontists and clinicians to accurately assess and approve treatment plans.
Innovation Solution
The system optimizes a virtual camera position relative to a 3D digital dental model to generate an incisal view that maximizes the visibility of occlusal, labial, and lingual surfaces of the incisors, using techniques such as bounding box inclusion and tilt angles based on the dental arch type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional views of three-dimensional dental models are used, then the display system is simple and easy to operate, but important dental features are occluded and cannot be clearly assessed
Solution Approach 1:
The patent introduces a new viewing dimension by optimizing the virtual camera position to generate an incisal view that looks down onto the occlusal surfaces of incisors. This dimensional change in viewing angle reveals dental features (labial, occlusal, and lingual surfaces) that are occluded in conventional views, directly resolving the information loss problem without adding physical device complexity
Solution Approach 2:
The system changes the parameter of camera position (position and orientation) to optimize the view of dental features. By adjusting the virtual camera's position relative to the 3D dental model and calculating optimal tilt angles based on dental arch type, the system maximizes visibility of critical tooth surfaces while maintaining the simplicity of the software-based solution
2Measurement precision
If the virtual camera position is optimized to maximize visibility of occlusal, labial, and lingual surfaces, then the assessment accuracy improves, but the calculation and positioning complexity increases
Solution Approach 1:
The system performs preliminary calculations to determine the optimal virtual camera position before generating the incisal view. By pre-calculating the camera position based on the dental model's geometry and dental arch type, and by establishing predetermined tilt angles, the system achieves high measurement precision while keeping the actual view generation process simple and efficient
Solution Approach 2:
The system uses the geometric properties of the dental model itself to determine the optimal camera position. By calculating tilt angles based on the dental arch type (upper or lower) and using the model's own structure as the reference frame, the system achieves self-service optimization without requiring external complex equipment or manual adjustment mechanisms

AI summary
System, methods, and apparatus for displaying alternative incisal views of a patient's three-dimensional (3D) digital model are disclosed. An incisal view may include maximal portions of labial, lingual, and occlusal incisor tooth surfaces. Some methods may include accessing the 3D digital model of the patient's upper or lower dental arch, optimizing a virtual camera position relative to the 3D digital model to generate the incisal view having a maximized view of an occlusal surface, a lingual side, and a labial side and generating the incisal view based on the optimized virtual camera position.
