Dynamic Panoramic Slice for Dental Implant Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for planning dental implants using panoramic images are limited in accurately assessing the position and orientation of virtual implants in the jaw, as they distort inclined implants and may not intersect all implants, leading to incomplete visibility and poor representation.
Innovation Solution
A method where the panoramic representation is aligned with the axis of symmetry of the planned implant, allowing for local adaptation to planning data, enabling complete display of implants without distortion and allowing for real-time adjustment of implant position, inclination, and diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional panoramic image is used to display implants, then an overview of the complete dental status is provided, but inclined implants are displayed in a distorted manner or cut at an angle
Solution Approach 1:
The patent transitions from displaying implants in a fixed panoramic plane to dynamically adjusting the panoramic slice orientation to align with each implant's axis. This dimensional adjustment allows inclined implants to be displayed in their true orientation rather than appearing distorted or cut at angles, while maintaining the panoramic overview capability.
Solution Approach 2:
The panoramic slice orientation is made dynamic rather than static. The system automatically adapts the panoramic slice to align with the implant axis based on implant planning data, allowing the display to change dynamically according to the specific implant being viewed while maintaining overall contextual information.
2Quantity of substance
If a fixed panoramic slice is used, then the complete dental status is visible, but not all implants are visible when they are inclined
Solution Approach 1:
The system adjusts the panoramic slice orientation in three-dimensional space to align with inclined implant axes. This allows implants that would otherwise be out of plane and invisible in a fixed panoramic view to be displayed completely, increasing the number of visible implants without requiring multiple separate views.
Solution Approach 2:
The panoramic slice serves multiple functions simultaneously: it provides the traditional panoramic overview and also aligns with specific implant axes to ensure complete visibility. This multi-functionality allows a single panoramic display to serve both general assessment and specific implant evaluation purposes.
3Shape
If the panoramic slice is aligned with the jaw arch, then anatomical structures are clearly visible, but implant orientation assessment is compromised
Solution Approach 1:
The panoramic slice orientation dynamically adapts between anatomical alignment and implant alignment modes. When assessing implants, the slice automatically rotates to align with the implant axis, ensuring accurate orientation measurement while maintaining clear visualization of relevant anatomical structures in the new orientation.
Solution Approach 2:
The panoramic slice orientation is locally adapted to the specific region being assessed. In regions with inclined implants, the slice aligns with the implant axis to provide accurate orientation assessment, while in other regions it may maintain traditional anatomical alignment, allowing different parts of the image to have different optimal orientations.
