Dental Restoration Occlusal Design Using a Functional Bite Map
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental restoration methods often fail to accurately simulate occlusal interference, leading to potential misfit and functional issues between dental restorations and opposing dentition, which can result in discomfort and reduced longevity of the restoration.
Innovation Solution
A system and method utilizing a functional bite map to generate an interference model, allowing for the design of dental restorations that avoid occlusal interference by capturing the relative motion between dental arches and using this data to create a precise occlusal surface, ensuring harmonious interaction with the opposing dentition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional dental restoration methods are used without functional bite map simulation, then the manufacturing process is simpler and faster, but the occlusal fit and functional performance deteriorate
Solution Approach 1:
The functional bite map is created in advance by capturing the relative motion between dental arches at multiple bite positions before restoration fabrication. This preliminary action allows the interference model to be generated ahead of time, enabling precise occlusal surface design without adding complexity to the actual restoration manufacturing process.
Solution Approach 2:
The system creates a digital copy of the opposing dental arch's motion trajectory through the functional bite map. This virtual interference model serves as a precise template that guides the restoration design, allowing accurate occlusal fit to be achieved through digital simulation rather than physical trial-and-error methods.
2Reliability
If motion capture apparatus and interference model generation are implemented, then occlusal interference is minimized, but the fabrication process becomes more complex
Solution Approach 1:
The system replaces complex mechanical trial-fitting procedures with digital motion capture and interference modeling. By using sensors to capture bite position data and generating virtual interference models, the system substitutes physical experimentation with computational analysis, improving reliability while managing complexity through digital workflows.
Solution Approach 2:
The functional bite map serves as an intermediary that translates complex three-dimensional motion data between dental arches into a simplified interference model. This intermediate representation captures the essential occlusal relationships without requiring the full complexity of the original motion capture data, facilitating easier integration into restoration design.
3Manufacturing precision
If multiple bite positions are captured to generate interference model, then the occlusal surface design accuracy is improved, but the data collection time increases
Solution Approach 1:
The system captures bite data at discrete periodic positions (centric occlusion, protrusive, lateral) rather than continuous motion. This periodic sampling approach captures the essential occlusal relationships at key moments in the bite cycle, achieving sufficient accuracy for restoration design while minimizing data collection time compared to continuous recording.
