Orthodontic Guide Slot Appliance for Precise Tooth Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic treatments face challenges in efficiently guiding tooth movement without undesired rotation or tipping, particularly when using bracket systems that anchor to teeth, leading to complications such as anchor tooth movement.
Innovation Solution
The use of a series of removable appliances, including shells with guide slots and adjustment bands, to guide tooth movement along predefined trajectories, utilizing the dental arch as an anchor, and minimizing rotational forces through attachments and guide slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If bracket systems are used to anchor and guide tooth movement, then tooth repositioning can be achieved, but anchor tooth movement and undesired rotation or tipping occur
Solution Approach 1:
The invention extracts the anchoring function from individual tooth brackets and relocates it to the dental arch itself. The appliance anchors to the arch form rather than to specific teeth, eliminating the problem of anchor tooth movement while maintaining precise control over tooth repositioning.
Solution Approach 2:
The appliance serves as an intermediary between the dental arch and individual teeth. Rather than directly anchoring to teeth with brackets, the appliance uses the dental arch as an intermediate structure to distribute and control forces, preventing undesired rotation and tipping of anchor teeth.
2Ease of operation
If traditional bracket systems are used, then tooth movement can be controlled, but rotational forces and tipping occur during adjustment
Solution Approach 1:
The invention adds a dimensional constraint by incorporating a guide slot that directs tooth movement along a predefined three-dimensional trajectory. This guide slot prevents movement in unwanted dimensions (rotation and tipping) while allowing controlled movement in the desired direction, eliminating harmful rotational forces.
3Manufacturing precision
If successive appliances are used to move teeth through intermediate arrangements, then precise alignment is achieved, but treatment time increases
Solution Approach 1:
The appliance incorporates a guide slot with a predefined trajectory that has been designed in advance to account for the desired tooth movement path. This preliminary planning of the movement trajectory allows the tooth to be guided directly along the optimal path, reducing the need for multiple successive appliances and intermediate adjustments.
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
This approach allows for controlled, efficient tooth repositioning with reduced rotational forces, enabling precise alignment and adjustment of teeth in various orthodontic treatments.
Implementation Method 1
repositioning may be provided through a process that uses one or more positioning appliances that are utilized for aligning teeth. Such appliances may, for example, utilize a thin shell of material having resilient properties
Implementation Method 2
a guide slot formed therein configured to accommodate an attachment on the at least one tooth and to define an adjustment trajectory of the at least one tooth
Implementation Method 3
an adjustment band to generate force on the number of teeth to adjust the number of teeth along the adjustment trajectory

AI summary
The present disclosure provides methods, devices, and systems for adjusting a tooth position. A system for adjusting a tooth position can include an attachment configured to be attached to a tooth to be moved, a dental appliance including a guide slot configured to receive the attachment and to define an adjustment trajectory of the tooth, and an adjustment band to generate force on the tooth to move the tooth along the adjustment trajectory.
