Orthodontic Bracket Extension System for Bonding Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orthodontic brackets often detach from teeth due to insufficient adherent forces from the archwire, leading to instability during tooth alignment treatments.
Innovation Solution
The orthodontic bracket extension system includes a bracket base and a bracket base extension with an aperture, allowing the bracket base to be securely fixed to the bracket base extension, which is then mounted to the tooth, increasing the bonding surface area and enhancing adherent forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional orthodontic brackets are used with direct bonding to tooth surface, then the device complexity is low, but the reliability of bracket attachment deteriorates due to insufficient adherent forces causing detachment
Solution Approach 1:
The bracket system is divided into separate components: a bracket base that bonds to the tooth surface and a bracket body that holds the archwire. This segmentation allows the base to be optimized for bonding reliability while the body provides structural function, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The bracket base is disposed within an aperture of the bracket base extension, creating a nested configuration where the bracket base fits inside the extension structure. This nesting increases the bonding surface area through the extension while maintaining a compact overall structure, improving reliability without excessive complexity.
2Reliability
If bracket base surface area is increased to improve adherent forces, then the reliability of bracket attachment improves, but the device complexity increases due to additional extension components
Solution Approach 1:
The bracket base extension adds bonding surface area by extending in a direction perpendicular to the tooth surface, utilizing the third dimension (depth/extension away from tooth) rather than only expanding laterally. This increases adhesion area while maintaining a profile that doesn't excessively increase overall device complexity.
