Intraoral Scanning Guide for Accurate 3D Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for scanning the intraoral cavity lack guidance, leading to incomplete or inaccurate 3D data collection, which can result in suboptimal prosthodontic and orthodontic procedures due to inadequate scanning of critical areas and excessive focus on non-essential details, wasting time for both practitioners and patients.
Innovation Solution
A method and system that identify target parts within the intraoral cavity, determine spatial relationships between the scanning device and these parts, and display these relationships as a guide for accurate scanning, ensuring comprehensive and precise 3D data collection by defining scanning stations and their optimal orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the dental practitioner scans the entire intraoral cavity without guidance, then complete coverage is achieved, but time is wasted scanning non-essential areas and critical areas may still be missed
Solution Approach 1:
The system performs preliminary identification of target parts and determination of optimal scanning spatial relationships before the actual scanning process. By pre-calculating and displaying the scanning guide with target areas and recommended scanner positions, the system prepares the scanning path in advance, allowing the practitioner to efficiently scan only necessary areas with proper orientation, thus improving accuracy while reducing time
Solution Approach 2:
The system provides real-time feedback by displaying the scanning guide that shows target parts, ancillary parts, and recommended scanning spatial relationships. This feedback mechanism guides the practitioner's scanning actions, allowing them to adjust their scanning approach based on the displayed information, ensuring complete coverage of critical areas without wasting time on non-essential regions
2Reliability
If the dental practitioner focuses on detailed scanning of all areas, then comprehensive data is obtained, but the quality of critical areas may be insufficient due to lack of targeted scanning
Solution Approach 1:
The system applies local quality by differentiating between target parts, ancillary parts, and non-essential areas. It provides enhanced scanning guidance and higher resolution data collection specifically for target parts that are critical for the dental procedure, while maintaining adequate but not excessive detail for other areas. This ensures high-quality data where needed without compromising overall data completeness
3Measurement precision
If multiple scanning passes are performed to ensure complete coverage, then data accuracy improves, but productivity decreases due to repeated scanning
Solution Approach 1:
The system performs preliminary identification of all target parts and calculation of optimal scanning spatial relationships before scanning begins. By providing a complete scanning guide that maps out all necessary scanning positions and orientations in advance, the practitioner can achieve complete coverage in fewer passes, improving both accuracy and efficiency
Solution Approach 2:
The system provides feedback during scanning by displaying the scanning guide and allowing the practitioner to verify coverage. This real-time feedback enables the practitioner to confirm that all target areas have been adequately scanned, reducing the need for multiple review passes and improving overall productivity while maintaining data accuracy

AI summary
According to the invention, a method and system are provided for scanning, and for facilitating scanning of, an intraoral cavity. The target parts of the intraoral cavity that it is desired to have scanned are identified, and the spatial s relationships between a scanning device and the target parts of the intraoral cavity suitable for enabling said target parts to be scanned by said scanning device, are also identified or otherwise determined. These relationships are then displayed, and the displayed relationships are used as a guide for scanning the intraoral cavity.
