Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic treatment systems generate parasitic reaction forces on adjacent teeth due to the transmission of forces, reducing treatment effectiveness and altering interdental relations.
Innovation Solution
An orthodontic treatment system featuring a mobile connecting element and a rigid orthodontic working arch that individualizes forces and distributes parasitic reaction forces over the entire arch, using a plastic material like polyamide PA12 or PA6-6 and a metal core for optimal force transmission and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a rigid orthodontic working arch is used to transmit forces to teeth, then force transmission efficiency is improved, but parasitic reaction forces on adjacent teeth increase
Solution Approach 1:
The orthodontic working arch is segmented into multiple independent zones, each capable of exerting forces on specific teeth. This segmentation allows the arch to transmit forces efficiently to target teeth while isolating and minimizing parasitic reaction forces on adjacent teeth, resolving the contradiction between force transmission efficiency and harmful reaction forces.
2Productivity
If forces are applied to move a specific tooth, then tooth displacement is achieved, but interdental relations are altered
Solution Approach 1:
The orthodontic working arch incorporates zones with different local qualities - some zones are designed to be more rigid for effective force transmission to specific teeth, while other zones are more flexible to accommodate and preserve natural interdental relations. This local differentiation allows effective tooth displacement while maintaining overall dental arch stability.
3Manufacturing precision
If a mobile connecting element is used to individualize forces, then force individualization is improved, but device complexity increases
Solution Approach 1:
The orthodontic working arch incorporates mobile connecting elements that can dynamically adjust their position and orientation based on the specific teeth being treated. This dynamic capability allows precise force individualization for each tooth while the modular design keeps the overall device complexity manageable through standardized components.

AI summary
The invention relates to an orthodontic working arch wire (2) for moving at least one tooth of a dental arch of patient to be treated from a first spatial configuration toward a second spatial configuration, including an element for connecting (42) to the tooth to be treated, which is intended to be attached onto the tooth being treated by snap-fitting onto a bracket glued onto one of the surfaces of said tooth, the working arch wire being rigid, the connecting element being movable relative to the orthodontic working arch wire and connected to the orthodontic working arch wire by elastically deformable connecting means (43, 43a).
