Detachable Orthodontic Bracket With Interlocking Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional removable orthodontic appliances lack the precision and strength of fixed appliances, often causing discomfort and inefficiency due to improper fit and limited tooth movement capabilities.
Innovation Solution
A detachable orthodontic bracket and wire system that can be precisely attached to a bonded base on a tooth, featuring interlocking elements and a framework of primary and secondary frame wires to provide strong, guided orthodontic forces, enhancing the alignment of teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional removable orthodontic appliances are used, then minimal visibility during casual interactions is achieved, but precision and strength of tooth repositioning are insufficient
Solution Approach 1:
The orthodontic appliance is divided into separate components: a removable appliance body and detachable bracket assemblies that can be attached to individual teeth. Each bracket assembly includes a bracket body with attachment means for securing to the tooth surface, allowing precise positioning while maintaining overall appliance removability.
Solution Approach 2:
Bracket assemblies serve as intermediary components between the removable appliance body and the tooth surfaces. These brackets provide precise attachment points and force transmission paths, enabling fixed-appliance-level precision while the appliance remains removable for hygiene and comfort.
2Ease of operation
If conventional removable orthodontic appliances are used, then ease of removal is maintained, but strength and robustness for significant tooth repositioning are lacking
Solution Approach 1:
The appliance transitions between two states: when brackets are attached to teeth, the system provides fixed-appliance strength for force application; when brackets are detached, the appliance becomes fully removable for hygiene. This dynamic configuration allows the system to adapt its mechanical properties based on operational needs.
Solution Approach 2:
Brackets are pre-attached to teeth before the removable appliance is inserted. This preliminary attachment ensures that when the appliance is in place, the brackets provide immediate structural support and force transmission paths, enabling strong and robust tooth repositioning capabilities.
3Illumination intensity
If lingual placement of arch wires is used, then minimal visibility is achieved, but accessibility and ease of adjustment are reduced
Solution Approach 1:
The bracket assembly is segmented into a bracket body attached to the tooth and a wire engagement portion that interfaces with the removable appliance. This segmentation allows the bracket to be positioned optimally on the tooth surface while maintaining easy accessibility from the appliance side for wire insertion and adjustment.
Solution Approach 2:
The bracket design incorporates universal features that work with both lingual and labial placements, as well as with different wire configurations. The bracket includes multiple engagement points and adjustable elements that accommodate various clinical requirements, making it versatile for different treatment scenarios.

AI summary
A detachable orthodontic bracket and wire system includes bracket bases, brackets, and an arch wire for guiding alignment of teeth. The bracket bases are positioned on a lingual surface and/or a facial surface of the teeth. Each bracket base includes a first surface, a second surface, and at least one first interlocking element. The first surface is rigidly attached to the lingual surface and/or the facial surface of the teeth. The second surface opposes the lingual surface and/or the facial surface of the teeth. The first interlocking element is attached to and positioned in a direction substantially perpendicular to or parallel to the second surface of each bracket base. The brackets include at least second interlocking element that interlocks with the first interlocking element. The arch wire is inserted through a slot channel of each bracket. The bracket and the arch wire are infused and rigidly anchored within enclosing layers.
