Dental Wire Supporter with Segmented Limiter for Orthodontic Friction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orthodontic treatments face challenges with increased treatment time due to intensified friction between orthodontic wires and brackets, particularly when moving anterior teeth rearward, leading to lateral movement and tilting of teeth.
Innovation Solution
A dental wire supporter with a limiter and support base that restricts the movement of orthodontic wires, featuring a wire hole with one side blocked and the other open, to prevent excessive movement and reduce friction, integrated with an orthodontic device including arch wires, guide brackets, and traction members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional orthodontic treatment moves anterior teeth rearward through three brackets, then tooth alignment is achieved, but friction between brackets and wire intensifies causing treatment time to increase
Solution Approach 1:
The invention divides the wire path into multiple segments by introducing intermediate wire supporters between the brackets. Instead of a single continuous wire passing through three brackets, the wire is segmented into multiple sections supported by additional intermediates, which distributes the friction and reduces resistance at each contact point, thereby improving treatment efficiency and reducing duration.
Solution Approach 2:
The invention introduces intermediate wire supporters as mediator elements between the brackets and the wire. These intermediaries provide additional support points that reduce the direct friction between the wire and brackets, acting as buffer zones that facilitate smoother wire movement and reduce overall treatment time.
2Manufacturing precision
If orthodontic wire passes through multiple brackets during rearward movement, then tooth alignment is achieved, but lateral movement and tilting of teeth occur due to intensified friction
Solution Approach 1:
By segmenting the wire path with intermediate supporters, the invention creates multiple controlled support points that stabilize the wire's position. This segmentation prevents the wire from deviating laterally or causing tooth tilting, as each segment is independently supported, thereby maintaining tooth orientation stability while achieving precise positioning.
Solution Approach 2:
The intermediate wire supporters act as mediators that stabilize the wire's trajectory between brackets. These intermediaries prevent lateral movement by providing continuous support, ensuring the wire moves smoothly in the intended direction without causing unwanted tooth tilting or rotation, thus maintaining compositional stability.
3Ease of operation
If wire hole is completely open for wire insertion, then wire placement is easy, but wire movement is not limited causing excessive displacement
Solution Approach 1:
The wire hole is designed with non-uniform properties: one end is open for easy wire insertion, while the other end is blocked to limit wire movement. This local differentiation of the wire hole's quality allows simultaneous achievement of easy wire placement and controlled wire position, resolving the contradiction between operational ease and position control.
Solution Approach 2:
Instead of making the wire hole completely open or completely closed, the invention inverts the expected design by blocking one end while keeping the other open. This inverted approach allows the wire to be easily inserted from the open end while the blocked end prevents excessive movement, achieving both ease of operation and position control.

AI summary
Disclosed are a dental wire supporter, which supports an orthodontic wire and limits the movement of the orthodontic wire in a predetermined direction, and an orthodontic device (orthodontic system) having the same. The dental wire supporter includes a limiter having a wire hole into which an orthodontic wire is inserted, and a support base provided at the limiter in order to fix the limiter to a tooth. One side of the wire hole is blocked and an opposite side of the wire hole is open so that the limiter supports the end of the orthodontic wire in a longitudinal direction of the orthodontic wire.
