Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing maxilla repositioning implants are difficult to manufacture, lack stability, result in unaesthetic appearance, and cause unpleasant wearing comfort due to soft tissue coverage, with potential complications and medical side effects.
Innovation Solution
A maxilla repositioning implant with a base and connection portion connected via retaining brackets, allowing for improved manipulability and simplified insertion, utilizing patient-specific geometry and materials like titanium or magnesium alloy, and designed for minimal material use and tissue compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate plates are used for maxilla repositioning implant, then the adaptability to patient-specific geometry is improved, but the device complexity and difficulty of insertion increase
Solution Approach 1:
Multiple separate plates are connected to each other via retaining brackets to form a unified implant structure. The retaining brackets mechanically link the plates together, allowing the implant to maintain patient-specific geometry adaptation while reducing overall device complexity and simplifying the insertion procedure.
Solution Approach 2:
The implant is divided into multiple plates that can be independently adapted to different regions of the maxilla, with retaining brackets connecting them. This segmentation allows each plate to be customized for patient-specific geometry while the connecting brackets integrate them into a cohesive structure.
2Strength
If traditional maxilla repositioning implants are used, then the structural integrity is maintained, but the manipulability and ease of insertion are reduced
Solution Approach 1:
The implant structure incorporates retaining brackets that allow for dynamic manipulation during insertion. The brackets enable the plates to be positioned and adjusted before final fixation, improving ease of operation while maintaining structural integrity through the rigid connection provided by the brackets.
3Stability of the object's composition
If more material is used in the implant, then the stability and strength are improved, but the aesthetic appearance and tissue compatibility worsen
Solution Approach 1:
The implant is segmented into multiple plates connected by retaining brackets, allowing material to be distributed only where structurally necessary. This segmentation enables stability to be achieved with minimal material, reducing interference with soft tissue and improving aesthetic appearance.
Solution Approach 2:
Material is concentrated in specific locations where structural support is needed, such as in the plates that contact the maxilla and in the retaining brackets that connect the plates. Areas not requiring structural support use minimal material, improving tissue compatibility and aesthetics while maintaining overall stability.
