Indirect Bonding Model Targets for Precise Orthodontic Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic procedures face challenges in accurately placing orthodontic appliances on teeth, leading to repeated treatments and deviations from the desired treatment plan due to the reliance on mechanical stops that protrude from the model dental surfaces, which can hinder precise alignment and bonding.
Innovation Solution
The use of targets on physical models that lack outwardly protruding mechanical stops, featuring recesses and optical markings to facilitate precise placement of orthodontic appliances, allowing for accurate alignment and bonding without the need for physical anchoring, and enabling the use of transfer trays for indirect bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If mechanical stops protruding from model dental surfaces are used to position orthodontic appliances, then the appliances can be physically anchored to the model, but the placement precision deteriorates due to interference with accurate alignment
Solution Approach 1:
The patent removes the mechanical stops that protrude from the model dental surfaces, eliminating the source of interference with precise alignment. Instead of using protruding stops for positioning, the invention uses recesses that receive the appliances without obstructing the bonding process or compromising placement accuracy.
Solution Approach 2:
Instead of using protruding mechanical stops to anchor appliances, the invention inverts the approach by using recesses (indentations) in the model surfaces to receive and position the appliances. This inversion eliminates the interference caused by protruding stops while maintaining physical anchoring functionality.
2Productivity
If traditional indirect bonding methods are used with protruding mechanical stops, then the bonding process can proceed, but repeated treatments are required due to inaccurate placement
Solution Approach 1:
The patent replaces the mechanical stop system with an optical marking system. Instead of relying on physical protrusions for positioning, the invention uses visual targets and markings that guide precise placement without mechanical interference, thereby improving both accuracy and treatment reliability.
Solution Approach 2:
The invention incorporates optical markings and visual targets on the model surfaces that provide clear visual feedback for accurate appliance placement. These markings use color or optical contrast to indicate precise positioning points, replacing the inadequate mechanical stop system.
3Strength
If outwardly protruding mechanical stops are used for appliance placement, then physical anchoring is achieved, but the alignment and orientation precision deteriorates
Solution Approach 1:
The patent introduces optical markings and visual targets as intermediaries between the model and the orthodontic appliances. These visual guides mediate the positioning process, allowing precise alignment and orientation without the interference of protruding mechanical stops that compromise bonding quality.
4Ease of operation
If mechanical stops are used to position appliances on the model, then the appliances can be secured, but the bonding quality deteriorates due to interference with the bonding process
Solution Approach 1:
The invention removes the protruding mechanical stops that interfere with the bonding process. By extracting this harmful element, the bonding quality is improved while appliance securing is maintained through the use of recesses and visual targeting systems.
