Removable Traction Bracket for Orthodontic Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic brackets have a fixed traction hook that can scratch the oral mucosa and do not allow the arch wire to fully express the torque angle of the main groove, leading to incomplete tooth correction.
Innovation Solution
A traction bracket design featuring a cylindrical traction component with an arrestment-traction hole and a threaded inner wall, allowing for the insertion of a traction bolt to assist in sliding and an arrestment bolt to secure the arch wire, reducing clearance angles and enhancing tooth movement control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the traction hook is welded directly to the bracket body, then the traction component is firmly fixed, but the protruding traction hook scratches oral mucosa and cannot be removed when unneeded
Solution Approach 1:
The patent extracts the harmful protruding traction hook from the bracket body by creating a separate removable traction component that inserts into a hole through the bracket. This allows the traction function to be separated from the bracket structure, eliminating the scratching problem while maintaining firm fixation when needed.
Solution Approach 2:
The patent transforms the static welded traction hook into a dynamic removable component. The traction component can be inserted and removed from the bracket body through the arrestment-traction hole, allowing it to be present only when needed for tooth movement, thus avoiding continuous contact with oral mucosa.
2Stability of the object's composition
If the arch wire is smaller than the main groove of the bracket, then the arch wire fits within the groove, but an angle of clearance between 10° and 24° is generated preventing full expression of torque angle
Solution Approach 1:
The patent introduces the arrestment bolt as an intermediary element that contacts both the arch wire and the bracket body. This mediator transmits the torque force from the arch wire to the bracket, enabling full expression of the torque angle even when the arch wire is smaller than the groove, by eliminating the clearance angle through mechanical contact.
3Object-affected harmful factors
If the traction component is made removable for comfort, then patient comfort is improved, but convenient installation and removal mechanism is needed
Solution Approach 1:
The patent designs the traction component as a nested structure that inserts into a cavity within the bracket body. The cylindrical traction component with threaded outer wall nests into the arrestment-traction hole, providing a simple push-in installation mechanism that is both comfortable for the patient and easy to operate for the orthodontist.
Solution Approach 2:
The patent prepares the bracket body in advance by creating the arrestment-traction hole with appropriate dimensions and threading. This preliminary preparation allows the traction component to be easily installed by simply inserting and threading it, without requiring complex installation procedures, thus maintaining patient comfort while ensuring ease of operation.

AI summary
The present disclosure discloses a traction bracket, an orthodontic system, and an orthodontic method thereof. The traction bracket includes a traction component, a main body, a cover body and a connecting component, wherein a surface of the main body is provided with a main groove, the main body is provided with a arrestment-traction hole, one end of the arrestment-traction hole is opened at a surface of the main body to form a traction hole, and another end of the arrestment-traction hole is opened at the main groove of the main body to form an arrestment hole, the traction component matches and is connected to the arrestment-traction hole, the main body is connected to the cover body via a connecting component, and the bottom surface of the cover body matches the surface of the main body and covers the main groove. The traction component of the traction bracket according to the present disclosure can be easily installed, and is equipped with bolt accessories in two specifications, i.e., a traction bolt and an arrestment bolt. The traction bolt can facilitate sliding of the bracket. When the traction bolt is replaced with an arrestment bolt, the movement of the bracket and the arch wire can be stopped, to strengthen anchorage, achieve removal of the clearance between the arch wire and the groove, and achieve the correction effect of accurate expression of the torque of the bracket.
