Adjustable Orthodontic Bracket with Pivoting Rotor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional orthodontic brackets have fixed slot angles and inclinations, making them inadequate for treating patients with irregular teeth arrangements, as they cannot be easily adjusted to match the unique requirements of each patient, leading to suboptimal treatment outcomes.
Innovation Solution
An adjustable bracket design that separates the bracket slot from the main body, allowing the rotor to be pivoted and adjusted at various angles within a smooth curved base groove, enabling the bracket slot to match the arch wire route and tooth arrangement, thus allowing for customizable torque, tip, and torsion adjustments without replacing the bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bracket slot is fixed at a specific angle and inclination, then the bracket structure is simple and easy to manufacture, but it cannot adapt to patients with irregular teeth arrangements
Solution Approach 1:
The bracket is divided into two main segments: a base body that remains fixed and provides structural support, and a rotor that can be rotated independently to adjust the bracket slot angle. This segmentation allows the slot orientation to be customized for each tooth while keeping the overall bracket structure relatively simple and manufacturable.
Solution Approach 2:
The rotor component introduces dynamic adjustability to the otherwise static bracket structure. The rotor can be rotated to different angles and locked in place, transforming the fixed bracket slot into an adjustable one, thereby adapting to various tooth arrangements without requiring multiple different bracket designs.
2Adaptability or versatility
If different bracket types with different slot angles are used for different patients, then the orthodontic treatment can be precisely tailored, but the device complexity and inventory requirements increase
Solution Approach 1:
A single base body design can accommodate multiple rotor components with different slot angles, or the same rotor can be rotated to provide different effective angles. This multi-functionality allows one bracket type to serve multiple patients with different tooth arrangements, eliminating the need to manufacture and stock multiple specialized bracket types.
Solution Approach 2:
Instead of manufacturing different brackets with fixed parameters for different patients, this invention allows the bracket slot angle parameter to be changed dynamically by rotating the rotor. This single parameter adjustment achieves customization without requiring complex multi-version manufacturing processes.
3Ease of operation
If the bracket slot angle is fixed, then the bracket is easy to operate and install, but it cannot be adjusted to match the arch wire route for irregular teeth
Solution Approach 1:
The rotor is pre-designed with a smooth curved surface that fits into a corresponding base groove, allowing for smooth rotation without requiring complex alignment procedures during installation. The preliminary design of this interface simplifies the adjustment operation while maintaining ease of initial bracket installation.
Solution Approach 2:
The rotor features a spherical or spheroidal surface that rotates within a matching curved base groove. This spherical geometry provides smooth, continuous rotation and easy adjustment to any angle, making the bracket adaptable to various arch wire routes while maintaining simple, intuitive operation.
