Retaining-Bracket Maxilla Implant for Precise Segment Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing maxillary repositioning implants are difficult to manufacture, lack stability, result in unaesthetic appearance, cause discomfort, and have common complications and adverse medical side effects.
Innovation Solution
A maxillary repositioning implant with a base and connecting section, connected via retaining brackets, allowing for simplified insertion and improved manipulability, featuring a stress-optimized design with minimal material usage and enhanced biocompatibility, manufactured using patient-specific CAD/CAM processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional maxillary repositioning implants are used, then fixation function is provided, but manufacturing difficulty increases and stability is insufficient
Solution Approach 1:
The implant is divided into multiple separate plate components (base plate, connecting section plate, and retaining bracket) that are manufactured independently and then assembled. This segmentation allows each component to be manufactured using standard processes with lower difficulty, while the assembled structure provides enhanced stability through distributed fixation points across the maxillary segments.
2Object-affected harmful factors
If conventional maxillary repositioning implants are used, then fixation function is provided, but appearance becomes unaesthetic and patient comfort decreases
Solution Approach 1:
The retaining bracket is designed as a separate removable component that can be extracted after the maxillary segments are fixed in the correct position. This allows the implant structure to be minimized or removed from the aesthetic zone once healing begins, improving appearance while maintaining fixation reliability during the critical initial healing period.
3Device complexity
If conventional maxillary repositioning implants are used, then fixation function is provided, but device complexity increases
Solution Approach 1:
The base plate and connecting section plate are pre-shaped with predetermined geometries and attachment interfaces before the surgical procedure. The retaining bracket is also prepared in advance with specific engagement features. This preliminary preparation of components with standardized shapes and connection mechanisms simplifies the actual insertion procedure, reducing surgical complexity while maintaining effective fixation.
