Orthodontic Remodeling Device with Inverted Pushing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic devices with arch wires can only pull teeth inward, limiting their effectiveness in correcting irregular teeth and requiring longer correction times.
Innovation Solution
An orthodontic remodeling device with a sleeve and screw rods that allows for the outward pushing of indented teeth, using tooth coupling rings for uniform force distribution, enabling arch wires to apply corrective forces for efficient tooth positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If arch wires are used to pull teeth inward, then teeth can be corrected, but the correction effect is limited and slow for irregular teeth located inward of the regular dentition line
Solution Approach 1:
Instead of pulling teeth inward with arch wires, the invention applies pushing force outward from the inner side of teeth using a remodeling device. This inverted approach directly addresses irregular teeth located inward of the regular dentition line by pushing them outward, significantly improving correction efficiency and reducing treatment time.
2Productivity
If a sleeve with screw rods is used to push teeth outward, then correction effectiveness is improved, but device complexity increases
Solution Approach 1:
The remodeling device is divided into functional segments: a sleeve containing screw rods for force application, tooth coupling rings for tooth engagement, and connecting structures. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and effectiveness.
Solution Approach 2:
The tooth coupling ring acts as an intermediary between the screw rod and the tooth. It transmits the pushing force from the screw rod to the tooth while distributing the force uniformly across the tooth surface, improving correction effectiveness without requiring direct contact between the screw rod and tooth.
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 device enables rapid and efficient correction of irregular teeth by pushing them outward, reducing correction time and improving the effectiveness of subsequent arch wire treatments.
Implementation Method 1
A tooth pushing member is engaged with the first assembling portion. The sleeve is rotatable to move the first screw rod toward or away from the tooth pushing member

AI summary
An orthodontic remodeling device includes a sleeve having first and second screw holes in two ends thereof. The first and second screw holes have opposite thread directions. A first screw rod includes a first threaded portion threadedly engaged with the first screw hole and a first assembling portion exposed outside of the sleeve. A second screw hole includes a second threaded portion threadedly engaged with the second screw hole and a second assembling portion exposed outside of the sleeve. Two tooth pushing members are respectively engaged with the first and second assembling portions. Each tooth pushing member includes at least one tooth coupling ring mounted on at least one tooth of a patient for pushing the at least one tooth outward. The sleeve is rotatable to move the first and second screw rods toward or away from each other to change a relative position between the two tooth pushing members.
