Orthodontic Bracket Retention Anchor for Indirect Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional indirect bonding techniques for orthodontic brackets face challenges in maintaining the precise position of brackets within the bonding tray, leading to potential repositioning or premature release during production and bonding, which can affect the accuracy of tooth movement in orthodontic treatments.
Innovation Solution
The introduction of a bracket configuration featuring a bracket base, a bracket body, and a bracket retention anchor that assists in anchoring the bracket to the matrix material of the bonding tray, ensuring stable positioning and preventing repositioning or premature release during the bonding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional indirect bonding techniques are used without retention anchors, then the bonding process is simpler, but the bracket position stability deteriorates leading to repositioning or premature release
Solution Approach 1:
The bracket is divided into distinct functional components: the bracket base for bonding to the tooth, the bracket body for holding the archwire, and the bracket retention anchor for securing to the matrix material. This segmentation allows each component to perform its specific function optimally, with the retention anchor specifically addressing the stability issue without complicating the bonding or archwire engagement functions.
Solution Approach 2:
The bracket retention anchor acts as an intermediary element that connects the bracket assembly to the matrix material of the bonding tray. This intermediary component provides a mechanical interface between the bracket and the tray, ensuring stable positioning during the bonding process without interfering with the adhesive bonding mechanism or the archwire slot function.
2Manufacturing precision
If brackets are firmly held in the bonding tray, then placement precision is improved, but the difficulty of bracket release from the tray increases
Solution Approach 1:
The retention anchor provides dynamic holding during the bonding process when firm attachment is needed, but allows for controlled release when the bonding is complete. The mechanical engagement between the retention anchor and the bonding tray can be designed to maintain stability under bonding forces while permitting deliberate removal, balancing holding strength with release ease.
3Stability of the object's composition
If the bracket configuration includes retention anchors, then resistance to repositioning is improved, but the device complexity increases
Solution Approach 1:
The retention anchor is a localized feature on the bracket that provides specific functional quality for stability without requiring changes to the entire bracket structure. By concentrating the stability function in a dedicated local component rather than redesigning the whole bracket, the solution adds minimal complexity while effectively addressing the repositioning issue.
