Custom Orthodontic Bonding Tool with Interlocking Facial and Lingual Bodies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic appliance placement methods, such as indirect bonding, are time-consuming, technique-sensitive, and prone to errors, leading to poor bond reliability and increased patient treatment time, while direct bonding lacks precision and control over adhesive delivery.
Innovation Solution
Custom tools with patient-specific designs, comprising a facial body and lingual body that interlock to position orthodontic appliances accurately on teeth, allowing for precise placement and bonding, reducing the need for external templates and improving adhesive control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If indirect bonding is used with transfer trays, then precise placement of orthodontic appliances is achieved, but the process becomes time-consuming and technique-sensitive
Solution Approach 1:
The custom tool is divided into a facial body and a lingual body that can be separately manufactured and then assembled together. This segmentation allows for simplified manufacturing of each component while maintaining the overall precision function, reducing the complexity and time of the bonding process
Solution Approach 2:
The custom tool acts as an intermediary device between the orthodontic appliances and the patient's teeth. It provides a simplified interface that guides appliance placement directly onto the teeth without requiring complex transfer trays or multiple steps, thereby maintaining precision while reducing treatment time
2Measurement precision
If indirect bonding with external templates is used, then appliance placement accuracy is improved, but device complexity and susceptibility to damage increase
Solution Approach 1:
The facial body and lingual body are merged into a single integrated custom tool assembly that functions as one unit during appliance placement. This merging eliminates the need for separate external templates and transfer trays, reducing overall device complexity while maintaining placement accuracy through the interlocked design of the two bodies
3Productivity
If direct bonding is used, then treatment time is reduced, but placement precision and adhesive control are compromised
Solution Approach 1:
The custom tool is designed to be self-aligning on the patient's teeth through the interlocking facial and lingual bodies. This self-service mechanism automatically ensures precise appliance placement without requiring complex external guidance systems, enabling direct bonding with both speed and precision
