Two-Component Orthodontic Bracket for 3D Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orthodontic treatments lack complete three-dimensional control, especially in the initial stages, leading to prolonged treatment times and potential side effects like orthodontic root resorption due to the use of thicker wires for torquing.
Innovation Solution
A two-component orthodontic bracket system comprising a wire component and a tooth component that engages and locks to provide better three-dimensional control, allowing for simultaneous tooth movement and reducing the need for rigid wires by utilizing small cross-section wires with enhanced lever arm length for effective torsional forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional single-component brackets with rectangular slots are used, then the bracket structure is simple and easy to manufacture, but complete three-dimensional control of tooth movement is not achieved especially in initial stages
Solution Approach 1:
The bracket is divided into two separate components: a tooth component that attaches to the tooth and a wire component that engages the arch wire. These components lock together to form the complete bracket assembly, enabling three-dimensional control while maintaining manufacturing simplicity through modular design
Solution Approach 2:
The invention adds a vertical dimension to the traditional bracket design by stacking the wire component above the tooth component with vertical engagement elements. This dimensional addition enables torque control and complete three-dimensional tooth movement control without complicating the manufacturing process
2Force
If thicker wires are used for torquing in conventional systems, then effective torsional forces are applied, but orthodontic root resorption occurs as a side effect
Solution Approach 1:
The wire component acts as an intermediary between the arch wire and the tooth component. It transmits torsional forces effectively through its engagement mechanism while using small cross-section wires that apply gentler forces, preventing root resorption while maintaining torque effectiveness
Solution Approach 2:
The wire component features asymmetric engagement elements with different geometries on opposite sides, enabling effective torque transmission through asymmetric force distribution. This allows small cross-section wires to generate sufficient torsional moments without requiring thick wire diameters that would cause harmful forces
3Reliability
If metal ligature ties are used in conventional brackets, then the wire is securely held, but oral hygiene is compromised and flossing becomes difficult
Solution Approach 1:
The invention completely removes metal ligature ties from the bracket system. Instead, the wire is secured through the locking mechanism between the wire component and tooth component, eliminating the hygiene problems associated with ligature ties while maintaining secure wire retention
Solution Approach 2:
The bracket assembly is designed to be easily detachable by the patient or caregiver. The wire component can be removed from the tooth component without special tools, enabling patients to perform oral hygiene and flossing independently while maintaining secure wire holding through the locking mechanism
4Productivity
If conventional brackets require bracket-wire play accommodation, then manufacturing is simpler, but treatment time is prolonged due to incomplete three-dimensional control
Solution Approach 1:
The engagement mechanism between wire component and tooth component provides dynamic adjustment capability. The wire component can adapt to slight variations in wire dimensions while maintaining precise three-dimensional control, eliminating the need for manufacturing tolerances that accommodate bracket-wire play
Solution Approach 2:
By adding vertical engagement elements, the invention creates a three-point contact system that eliminates play in all three dimensions. This vertical dimension of control prevents wire movement and ensures complete three-dimensional tooth control without requiring overly precise manufacturing tolerances
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates rapid three-dimensional alignment of teeth throughout treatment, shortening duration and promoting better oral hygiene by eliminating metal ligature ties and allowing easy flossing, while applying effective torsional forces without rigid wires.
Implementation Method 1
The force generated by the elastic deformation of the wire then pulls the teeth along with it as it moves to its original shape
Implementation Method 2
the alignment of the teeth occurs due to the elastic recoil of the wire
Implementation Method 3
the appliance will transmit the forces to move the teeth into alignment when the wire component and tooth component of the bracket are engaged to form the bracket assembly

AI summary
An orthodontic bracket consisting of two-components that are engaged and locked together to form the bracket assembly where the tooth component of the orthodontic bracket is semi-permanently glued to the tooth surface and the wire component of the orthodontic bracket is securely attached to the wire. When the wire component and the tooth component of the bracket assembly are engaged, the orthodontic wire that passes through the wire component of the bracket is deflected as a result; the alignment of the teeth occurs due to the elastic recoil of the orthodontic wire. The wire component of the bracket is completely detachable and re-attachable to the tooth component of the bracket.
