Indirect Bonding Tray Inspection for Accurate Bracket Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indirect bonding trays often have defects or misaligned dental brackets, leading to incorrect placements, arch wire bending, and prolonged orthodontic treatment procedures, which are time-consuming and costly.
Innovation Solution
A quality control system and method that uses digital models and image processing to compare and identify variances in indirect bonding trays and dental brackets, ensuring accurate alignment and placement by generating image models and comparing them to digital models, with features like bracket identification marks and light transmission analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If indirect bonding trays are manually inspected and loaded with dental brackets, then the process is simple and quick, but structural variances and misaligned brackets occur leading to incorrect placements
Solution Approach 1:
The system performs preliminary quality control inspection of indirect bonding trays before they are used in clinical applications. The image capture devices and processing system detect structural variances, defects in tooth pockets and bracket pockets, and incorrect bracket loading in advance, preventing these issues from occurring during actual bracket placement procedures.
Solution Approach 2:
The patent replaces manual visual inspection and manual bracket loading with an automated optical inspection system. Image capture devices capture images of the indirect bonding tray, and a processing system automatically analyzes these images to detect variances from the digital model, substituting mechanical/manual processes with optical and computational systems.
2Productivity
If defects in indirect bonding trays are not detected, then the manufacturing process remains fast, but incorrect bracket placement occurs requiring repositioning and replacement
Solution Approach 1:
The system establishes a feedback loop where the image processing system compares captured images of the indirect bonding tray against its digital model, identifies variances and defects, and provides information about these issues. This feedback enables corrective actions before the tray is used clinically, ensuring reliable bracket placement.
Solution Approach 2:
The quality control inspection is performed preliminarily before the indirect bonding tray is used for bracket placement. By detecting defects and variances in advance, the system prevents incorrect placements and the need for repositioning or replacement during clinical procedures.
3Manufacturing precision
If variances in indirect bonding tray structure are identified, then bracket placement accuracy improves, but additional inspection time is required
Solution Approach 1:
The system replaces time-consuming manual inspection with automated optical imaging and computer-based image processing. The image capture devices quickly capture images of the indirect bonding tray, and the processing system automatically compares these images to the digital model, significantly reducing inspection time compared to manual methods.
Solution Approach 2:
The inspection is performed preliminarily in the manufacturing or preparation phase rather than during clinical procedures. This timing allows for detection and correction of variances before the indirect bonding tray is used, preventing time loss during actual orthodontic treatment.
