Orthodontic Bracket Placement Guide for Precise Direct Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for accurately placing orthodontic brackets on teeth without indirect bonding trays, such as in crowded teeth conditions, result in deviations from digitally planned placements, leading to potential bracket collisions and suboptimal treatment outcomes.
Innovation Solution
The use of orthodontic bracket placement guides that provide graphical representations of teeth and brackets, including measurements and indicia, to assist clinicians in accurately positioning brackets according to a digital treatment plan, enabling direct bonding without indirect trays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct bonding is performed without indirect bonding trays in crowded teeth conditions, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The patent introduces a bracket placement guide as an intermediary tool between the clinician and the bracket bonding process. This guide includes graphical representations of teeth with indicated bracket positions and measurements, serving as a mediator that translates digital treatment plans into accurate physical placement without requiring indirect bonding trays, thus resolving the contradiction between ease of operation and placement precision
2Manufacturing precision
If indirect bonding trays are used for bracket placement, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the essential guiding function from the complex indirect bonding tray system and isolates it into a simplified bracket placement guide. This guide contains only the necessary information (graphical tooth representations, bracket position indicators, and measurements) to achieve precise placement, eliminating the need for complex tray structures while maintaining placement accuracy
3Ease of operation
If bracket placement deviates from digital plan, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The bracket placement guide incorporates feedback mechanisms by displaying graphical representations of the tooth and bracket with indicated measurements and positions. This visual feedback allows the clinician to verify bracket placement accuracy in real-time against the digital treatment plan, ensuring that simple direct bonding operations maintain high reliability and predictable treatment outcomes

AI summary
An orthodontic appliance placement guide with instructions to position an orthodontic appliance, such as an orthodontic bracket, on a tooth of a patient at a position corresponding to a digital position of a digital appliance on a digital tooth in a virtual model of teeth of the patient. The orthodontic appliance placement guide can include representations of the tooth and the orthodontic appliance positioned thereon. The orthodontic appliance placement guide can indicate measurements between reference features of the orthodontic appliance and tooth. A clinician can take measurements when placing the orthodontic appliance on the tooth to guide placement of the orthodontic appliance as instructed by the orthodontic appliance placement guide.
