Orthodontic Bracket Adhesive Indention Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Orthodontic brackets often detach from teeth, requiring frequent reattachment visits to the orthodontist, highlighting a need for an improved attachment system that prevents premature detachment while maintaining adhesive integrity.
Innovation Solution
The orthodontic bracket attachment system features a bracket with a wing on the facial side and discrete adhesive indentions on the lingual side, allowing for separate adhesive application and distribution, preventing the peeling off of one adhesive indention from affecting the entire surface area, unlike interconnected groove systems which disperse adhesive across the entire bracket surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is applied across the entire bracket surface, then adhesive coverage is maximized, but detachment of one area compromises the entire attachment
Solution Approach 1:
The bracket lingual surface is divided into multiple discrete adhesive indentions rather than a continuous surface. Each indention is a separate adhesive retention area, so that if adhesive fails in one indention, the other indentions remain intact and maintain bracket attachment. This segmentation isolates potential failure points while maintaining overall attachment reliability.
2Reliability
If interconnected grooves are used for adhesive distribution, then adhesive coverage is improved, but peeling off affects the entire surface area
Solution Approach 1:
The adhesive retention features are designed as discrete, non-interconnected indentions on the bracket lingual surface. Each indention is isolated from the others, preventing the propagation of detachment forces across the entire bracket surface. When adhesive is applied, it is contained within individual indentions, so failure in one location does not compromise adhesive integrity in other locations.
3Reliability
If separate adhesive indentions are used, then detachment is contained to local areas, but adhesive application precision is required
Solution Approach 1:
The bracket is pre-formed with discrete adhesive indentions during manufacturing, creating ready-made adhesive retention areas before the bracket is applied to the tooth. These pre-formed indentions guide adhesive placement and ensure proper distribution without requiring precise manual application, as the indentions themselves define where adhesive should be placed.
Solution Approach 2:
The bracket lingual surface has non-uniform geometry with specific localized indentions rather than a uniform surface. Each indention is strategically positioned and sized to optimize adhesive retention at critical locations, providing enhanced adhesive strength where needed while maintaining overall bracket performance.
