Adaptive Oral Scan Data Stitching for Scan Post Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing intraoral scanning and implanting process requires scanning gum data first, then digging a hole, and finally scanning with a scan post, leading to a dependency on gum data, which limits the scanning process and reduces accuracy if the scan post is installed before scanning.
Innovation Solution
Obtain scanning process information based on target oral cavity information, scan the target oral cavity to collect customized scan post data and dental and jaw data, perform calculations using a preset position transformation matrix, and stitch the data to achieve adaptive scan post data, thereby improving accuracy and reducing data dependency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gum data is scanned first, then scan post data is scanned, then scanning accuracy is improved, but scanning process complexity increases and work efficiency decreases
Solution Approach 1:
The patent inverts the traditional scanning sequence by scanning the scan post data first, then the gum data. This reversal eliminates the dependency relationship between the two scanning steps, allowing the scan post to remain installed throughout the entire process, thereby simplifying the overall workflow while maintaining high accuracy through coordinate system transformation
2Productivity
If scan post is installed before scanning, then work efficiency is improved, but scanning accuracy deteriorates due to data dependency
Solution Approach 1:
The patent applies parameter changes by transforming the coordinate system parameters. When the scan post is installed before scanning, the system uses coordinate transformation to map the scan post coordinates to the gum coordinate system, thereby maintaining scanning accuracy despite the changed installation timing, while allowing the scan post to remain in place for improved work efficiency
3Stability of the object's composition
If scan post data depends on gum data, then data consistency is maintained, but scanning flexibility is reduced
Solution Approach 1:
The patent introduces a coordinate transformation matrix as an intermediary between scan post data and gum data. This matrix establishes a mathematical relationship that allows independent scanning of both components while maintaining their spatial consistency, thereby eliminating data dependency and enabling flexible scanning sequences without compromising data consistency
