Removable Orthodontic Retainer with Magnetic Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic retention systems either interfere with the bite or complicate cleaning and maintenance, and lack flexibility in accommodating replacement teeth or adjusting to realign teeth post-treatment.
Innovation Solution
A removable orthodontic retention system featuring adjustable components with magnetic and mechanical retentive mechanisms that attach to fixed brackets on teeth, allowing for easy insertion and removal, and incorporating adjustable wires for realignment, while maintaining tooth position and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixed retainers are used to maintain tooth position, then tooth alignment is maintained, but they interfere with bite and complicate cleaning and maintenance
Solution Approach 1:
The retainer is divided into fixed components (brackets cemented to teeth) and removable components (wires that can be taken out). This segmentation allows the fixed brackets to maintain tooth position reliably while the removable wires can be easily cleaned and maintained separately, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The system transitions from a completely fixed retainer design to a dynamic system where components can be removed and reattached. The removable wire component can be taken out for cleaning and maintenance, providing adaptability that resolves the contradiction between maintaining alignment reliability and enabling easy cleaning.
2Reliability
If traditional retainers are used, then tooth position is retained, but they lack flexibility in accommodating replacement teeth or adjusting to realign teeth
Solution Approach 1:
The adjustable wire component can be modified in length and configuration to accommodate replacement teeth or realign shifted teeth. This dynamic adjustability provides versatility while the fixed brackets maintain reliable tooth position retention, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The retainer system serves multiple functions: it retains tooth position, accommodates replacement teeth, and allows for adjustments to realign teeth. This multi-functionality resolves the contradiction by making the system versatile enough to handle various scenarios while maintaining reliable retention.
3Adaptability or versatility
If adjustable components are added to allow realignment, then versatility is improved, but device complexity increases
Solution Approach 1:
The adjustable realignment components are segmented as separate removable wires rather than being integrated into the fixed bracket structure. This keeps the basic bracket structure simple while adding versatility through separate adjustable components, resolving the contradiction between adaptability and device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively maintains tooth alignment without interfering with bite or dental hygiene, simplifies the replacement of missing teeth, and allows for conversion between retention and treatment modes.
Implementation Method 1
The retention system also can include magnetic retention components to retain the removable component with respect to one or more teeth.
Implementation Method 2
Adjustments are made to the wires, which cause forces to be applied to the teeth, which in turn move the teeth.

AI summary
An orthodontic retention system includes a fixed component that remains on teeth and a component that attaches to this fixed component. The fixed component and the component have mating or interlocking parts. The component that mates with the fixed component can be removable. The component that mates with the fixed component can be adjustable. The retention system also can include magnetic retention components to retain the removable component with respect to one or more teeth. The retention system also can include an element that replaces as tooth.
