Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental prosthesis design systems lack flexibility in manipulating 3D models of prosthetic teeth, limiting the ability to customize dental prostheses based on individual patient needs and occlusion estimation.
Innovation Solution
The system presents a virtual multi-tooth prosthesis with 3D models of individual teeth relative to a patient's mouth, allowing operators to manipulate and modify parameters such as shape and occlusion through a computer-implemented interface, using motion simulation and collision detection to estimate occlusion and generate production data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a library of 3D models of prosthetic teeth is provided for dental prosthesis design, then the design process can be initiated with standardized components, but the flexibility to customize prostheses based on individual patient needs and occlusion estimation is limited
Solution Approach 1:
The system transforms static 3D models into dynamically manipulable virtual prostheses that can be adjusted in real-time. Operators can modify parameters such as tooth position, orientation, and shape, allowing the prosthesis to adapt to individual patient needs while maintaining a standardized base library for efficiency.
Solution Approach 2:
The invention enables modification of multiple parameters including position, orientation, shape, and occlusion characteristics of prosthetic teeth. These parameter changes allow customization of the prosthesis to match patient-specific anatomical and functional requirements while building upon standardized 3D model libraries.
2Productivity
If standardized 3D models of prosthetic teeth are used, then the design process is simplified and faster, but the precision and accuracy of fit and functionality based on individual patient occlusion are reduced
Solution Approach 1:
Standardized 3D models serve as pre-prepared templates that provide a head start in the design process. These preliminary models can be quickly selected and then refined through parameter modification to achieve patient-specific precision, combining the speed of standardization with the accuracy of customization.
Solution Approach 2:
The system incorporates occlusion estimation and analysis that provides feedback on how well the prosthesis fits patient-specific requirements. This feedback loop allows operators to adjust parameters iteratively, ensuring both efficient design and high precision in the final prosthesis configuration.

AI summary
Herein are provided methods, systems, computer-readable media, techniques and processes for crown or prosthesis manipulation in dental prosthesis design. These include presenting a 3D model of a multi-tooth prosthesis relative to an area to be reconstructed. An operator may manipulate one or more prosthetic teeth in that 3D model in order to alter the overall shape of the prosthesis. In various embodiments, the techniques may also include the determination of occlusion with respect to antagonist teeth - of the entire 3D model of the prosthesis and/or of individual 3D models of prosthetic teeth in the model. The position or shape of the 3D model of the prosthesis may be modified based on the occlusion.
