Magnetic Tooth Traction for Nerve-Sparing Impacted Tooth Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for extracting impacted teeth, such as dental surgery, cause pain, damage nearby nerves, and result in large cavities prone to bacterial growth due to direct extraction techniques.
Innovation Solution
A magnetic traction device comprising a first magnetic component fixed to a normal tooth and a second magnetic component fixed to the impacted tooth, utilizing an attractive magnetic force to gradually pull the impacted tooth towards the normal tooth, minimizing nerve damage and reducing cavity size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct extraction of impacted tooth is performed, then the impacted tooth can be removed, but nerve damage and large bone cavities occur
Solution Approach 1:
The magnetic components are installed on both the impacted tooth and adjacent normal teeth before extraction begins. The magnetic traction system is activated in advance to gradually guide the impacted tooth into a safer position, reducing the risk of nerve damage during the subsequent extraction procedure.
Solution Approach 2:
Magnetic field is introduced as an intermediary force between the extraction tool and the impacted tooth. The magnetic attraction gradually pulls the impacted tooth toward the normal teeth, serving as a mediating mechanism that reduces direct mechanical force and minimizes nerve damage.
2Productivity
If direct extraction of impacted tooth is performed, then the impacted tooth can be removed, but large bone cavities are created prone to bacterial growth
Solution Approach 1:
The magnetic traction system is activated before extraction to gradually move the impacted tooth into a more favorable position. This preliminary action allows for a more controlled extraction process that preserves more bone structure, resulting in smaller cavities that are less prone to bacterial growth.
3Object-affected harmful factors
If magnetic traction device is used, then nerve damage is avoided, but device complexity increases
Solution Approach 1:
The magnetic traction device is divided into separate components: magnetic components that are independently installed on the impacted tooth and on adjacent normal teeth. This segmentation simplifies the overall device structure, as each component is relatively simple and can be installed separately using conventional dental procedures.
Solution Approach 2:
The magnetic components serve multiple functions: they provide gradual traction force to guide the impacted tooth, act as anchors for the magnetic system, and can be integrated with existing dental restoration materials. This multi-functionality reduces the need for additional specialized equipment, thereby reducing overall device complexity.
