Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D scanning and modeling technologies in the dental industry face challenges in obtaining accurate data for designing dental prostheses, particularly due to inaccuracies in occlusion data post-medical procedures, leading to suboptimal prosthesis design.
Innovation Solution
A data processing method that involves obtaining and aligning upper and lower jaw data with various sets of occlusion data to generate alignment scan data, allowing for comparison and improved accuracy in dental prosthesis design by considering pre- and post-medical procedure data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If occlusion data is obtained after medical procedure, then treatment can be provided based on current oral cavity structure, but data accuracy deteriorates because the medical procedure has altered the original structure
Solution Approach 1:
The system performs preliminary actions by obtaining and storing occlusion data before the medical procedure is executed. This pre-procedure occlusion data is then used as a reference during prosthesis design, ensuring that the original oral cavity structure is preserved in the design process even after the procedure alters the actual structure.
Solution Approach 2:
The system creates a digital copy of the pre-procedure oral cavity structure through 3D scanning and stores it as reference data. This digital model serves as an accurate representation of the original structure, allowing designers to work with precise pre-procedure geometry without being affected by post-procedure structural changes.
2Adaptability or versatility
If only post-medical procedure scan data is used, then current oral cavity state is captured, but design accuracy deteriorates due to loss of pre-procedure structural information
Solution Approach 1:
The system merges multiple data sets including pre-procedure upper jaw data, pre-procedure lower jaw data, post-procedure upper jaw data, post-procedure lower jaw data, pre-procedure occlusion data, and post-procedure occlusion data into a comprehensive digital model. This integration allows the design system to access both historical pre-procedure structural information and current post-procedure state, enabling accurate prosthesis design that respects both the original anatomy and the current clinical situation.
