Orthodontic Bracket Bonding Jig With Discharge Holes and Viewing Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indirect bonding methods for orthodontic appliances face issues with excessive bonding agent spread, difficulty in seeing proper fastening, and increased working time due to the need for manual removal of excess agent and potential tooth damage.
Innovation Solution
An indirect bonding device with discharge holes for excess bonding agent and transparent windows for visual confirmation of fastening, allowing easy discharge and accurate alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an indirect bonding jig is used to bond brackets to teeth, then bracket bonding accuracy and ease of operation are improved, but excessive bonding agent spreads between the jig and tooth surface causing tooth damage risk and increased working time
Solution Approach 1:
The patent extracts the harmful excessive bonding agent from the bonding system by incorporating discharge holes in the jig body. These holes allow the excess bonding agent to escape outward during the bonding process, preventing it from spreading between the jig and tooth surface, thus eliminating the tooth damage risk while maintaining the ease of operation benefits of indirect bonding
Solution Approach 2:
The patent converts the potentially harmful excessive bonding agent into a beneficial flow by designing discharge holes that channel the excess agent outward. The bonding agent that would otherwise be harmful is now directed to flow away from the tooth surface, transforming a harmful factor into a controlled process element that prevents damage
2Adaptability or versatility
If an indirect bonding jig covers the entire tooth surface including labial and lingual surfaces, then comprehensive bracket placement is enabled, but visibility of fastening status is blocked making proper fastening difficult to verify
Solution Approach 1:
The patent applies local quality by making specific portions of the jig body transparent while maintaining coverage of other areas. The transparent windows are strategically placed to allow visibility of the fastening status at critical locations, while the rest of the jig body maintains its coverage function. This selective transparency resolves the contradiction by enabling both comprehensive coverage and visibility where needed
Solution Approach 2:
The patent utilizes optical properties (transparency/opacity) to resolve the visibility problem. By incorporating transparent windows in the jig body, the patent allows light to pass through, making the fastening status visible to the operator. This optical modification enables simultaneous achievement of comprehensive coverage and detectability of fastening status
3Reliability
If manual removal of excessive bonding agent is performed using tools like burrs, then complete removal is achieved, but working time increases and tooth damage risk increases
Solution Approach 1:
The patent applies preliminary action by designing the jig body with discharge holes that automatically remove excessive bonding agent during the bonding process itself. The excess agent is discharged outward as it is applied, preventing the need for subsequent manual removal steps. This preliminary discharge action eliminates the time-consuming and damaging manual removal process while ensuring complete removal of excessive agent
