Elastic Tooth Traction Bracket Installation for Nerve-Safe Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing impacted teeth often cause discomfort, pain, and risk nerve damage, and result in large post-extraction sockets and bacterial growth due to direct extraction.
Innovation Solution
A dental instrument with a handle, extension, and protrusions is used to facilitate the installation of an impacted tooth traction device, comprising brackets and an elastic traction ligature, which gradually moves the impacted tooth away from adjacent nerves, reducing discomfort and nerve damage risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If direct extraction of impacted teeth is performed, then the tooth can be removed immediately, but it causes large post-extraction sockets, increases risk of nerve damage, and creates a conducive environment for bacterial growth
Solution Approach 1:
The patent applies preliminary action by first installing a bracket on the impacted tooth and attaching an elastic traction ligature before performing extraction. The ligature is stretched to create gradual traction force that moves the tooth away from nerves and creates space, preparing the environment for safer subsequent extraction or eruption.
Solution Approach 2:
The elastic traction ligature serves as an intermediary element between the bracket on the impacted tooth and the anchoring structure. It transmits and distributes traction force gradually, mediating the movement of the tooth away from vulnerable areas without direct surgical intervention.
2Productivity
If direct extraction of impacted teeth is performed, then the procedure is completed quickly, but it causes discomfort and pain to patients
Solution Approach 1:
The bracket installation and elastic ligature attachment are performed as preliminary actions before the actual extraction or eruption process. This preparation phase allows the tooth to be gradually mobilized, reducing the force required during final extraction and thereby decreasing patient pain and discomfort.
Solution Approach 2:
The elastic traction ligature provides dynamic, adjustable traction force that can be modified over time. The elastic nature allows for gradual increase in force as the tooth moves, optimizing the balance between extraction speed and patient comfort throughout the treatment process.
3Device complexity
If direct extraction of impacted teeth is performed, then the procedure is simpler, but it results in large post-extraction sockets that compromise adjacent teeth support
Solution Approach 1:
The preliminary installation of the bracket and elastic ligature system allows for controlled tooth movement before extraction. This preparation enables the tooth to be pulled through the bone gradually, creating smaller voids as it moves, rather than creating one large socket through direct extraction.
Solution Approach 2:
The elastic traction ligature acts as an intermediary that distributes the extraction force over time and space. By gradually mobilizing the tooth through the bone structure, it prevents the creation of large sudden voids that would compromise adjacent tooth support.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method minimizes pain and nerve damage by gradually moving the impacted tooth, allowing small bone voids to heal quickly, and reduces bacterial growth by avoiding direct extraction.
