Spring-Loaded Tooth Movement Device for Extrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic treatments face challenges in effectively applying tooth extrusion movement forces, often requiring multiple attachments and elastics, which can complicate the process and reduce efficiency.
Innovation Solution
The development of a spring-loaded tooth movement device integrated into orthodontic appliances that directly engages attachments on the teeth, allowing for precise and controlled tooth movement forces, including extrusion, without the need for extensive external elastic forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional braces or multiple attachments with elastics are used to apply tooth extrusion movement forces, then tooth movement can be achieved, but the device complexity increases and the ease of operation decreases
Solution Approach 1:
The patent combines the spring mechanism and attachment into a single integrated spring-loaded device that applies extrusion force directly to the tooth, eliminating the need for separate elastic components and multiple attachments. This merging of components reduces overall device complexity while maintaining effective force application.
Solution Approach 2:
The spring-loaded device is designed to automatically apply and maintain extrusion force without requiring external elastic components or additional adjustment mechanisms. The spring inherently provides the necessary force, making the system self-sufficient and reducing the number of parts needed.
2Manufacturing precision
If traditional braces require multiple clinical visits and adjustments to move teeth, then tooth repositioning can be achieved, but the loss of time increases
Solution Approach 1:
The spring-loaded device is pre-configured with the appropriate spring force and attachment geometry before being applied to the patient's tooth. This preliminary setup allows the device to immediately begin applying the correct extrusion force without requiring multiple adjustment visits, thereby reducing treatment time while maintaining precision.
3Reliability
If conventional orthodontic appliances are used, then tooth movement is possible, but the ease of operation and patient convenience are reduced
Solution Approach 1:
The invention extracts and eliminates the need for external elastic components and complex adjustment mechanisms from the traditional orthodontic system. By using a self-contained spring-loaded device that applies force directly, the system simplifies the application process and improves patient convenience while maintaining reliable tooth movement effectiveness.

AI summary
The present invention provides orthodontic appliances and systems, and related methods, for applying a force to a target tooth as an appliance is worn by the patient. One positioning appliance includes a tooth positioning appliance having teeth receiving cavities shaped to apply a positioning force to the patient's teeth. The appliance includes a spring-loaded tooth movement device disposed in the appliance so as to engage an attachment mounted on a surface of a patient's tooth and apply a force to the tooth.
