Intraoral Panoramic Imaging for Full Teeth Arrangement Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intraoral imaging apparatuses have a limited field of view, making it difficult to identify the position and type of each tooth and the relationship between them, limiting comprehensive observation of dental lesions and surrounding teeth.
Innovation Solution
An intraoral imaging apparatus and method that generates an optical panoramic image by stitching multiple optical images along the teeth arrangement direction, integrating with X-ray panoramic images for comprehensive observation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an intraoral camera with limited FOV is used to capture individual teeth images, then image quality and detail of individual teeth are improved, but the ability to observe the overall teeth arrangement and relationships between teeth deteriorates
Solution Approach 1:
The patent divides the overall teeth arrangement observation into multiple individual tooth images, then reconstructs the complete view by stitching these segmented images together in panoramic mode, resolving the contradiction between detailed individual views and overall arrangement observation
Solution Approach 2:
The patent transitions from a two-dimensional limited FOV view to a panoramic dimensional view by stitching multiple images along the teeth arrangement direction, enabling comprehensive observation of the entire teeth arch while maintaining individual tooth detail
2Loss of information
If multiple individual images are captured to cover the entire teeth arrangement, then the overall teeth arrangement observation is improved, but the complexity of image processing and identification deteriorates
Solution Approach 1:
The patent introduces a processor as an intermediary that automatically performs the complex stitching and identification tasks, taking multiple individual images as input and producing a panoramic view with identified tooth positions and lesions, thereby reducing the operational complexity for the user
Solution Approach 2:
The system performs automatic identification of tooth positions and lesions within the panoramic image without requiring manual intervention, allowing the device to serve itself in processing and analyzing the stitched images

AI summary
Proposed is an intraoral image displaying method. The intraoral image displaying method may include storing a plurality of optical images for the intraoral cavity including a teeth arrangement, generating an optical panoramic image for the entire teeth arrangement by stitching the plurality of optical images along a teeth arrangement direction, and displaying the optical panoramic image.
