Solution Overview

Problem

Existing methods for removing impacted teeth, such as traction techniques, face difficulties in passing a wire through the tooth due to the challenge of navigating the wire through a perforation and into a longitudinal cavity, often causing discomfort and potential damage to nearby nerves.

Innovation Solution

A guiding device with a hook and wire is used to facilitate the passage of the wire through the impacted tooth, where the hook is more resistant to deformation and has a curved shape to guide the wire through a transverse perforation and into a longitudinal cavity, optionally assisted by a tool with a handle and receiving portion to secure the hook and prevent rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wire is directly passed through a transverse perforation in the impacted tooth, then the wire can be positioned for traction, but the process is difficult and time-consuming

Engineering Contradiction:
Improveease of passing wire through toothVSAvoidoperation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent introduces a guiding device as an intermediary tool that includes a curved guide portion and a wire. The guide portion is inserted into the transverse perforation first, and then the wire is passed through the guide portion along a predetermined curved path. This intermediary guide device simplifies the complex task of directly threading the wire through the tooth perforation, making the operation easier and faster while ensuring proper wire positioning for subsequent traction treatment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The guiding device performs preliminary action by pre-establishing the correct spatial path and orientation for wire insertion. The curved guide portion is designed beforehand to match the required trajectory from the transverse perforation into the tooth root area. By preparing this guide structure in advance, the actual wire passing operation becomes straightforward, eliminating the need for complex manual threading during the procedure.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If traditional dental surgery is used to remove impacted teeth, then the tooth can be extracted, but it causes pain, leaves large bone cavities, and may damage nearby nerves

Engineering Contradiction:
Improvetooth extraction efficiencyVSAvoidpatient discomfort and nerve damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The invention segments the tooth extraction process into two distinct phases: first, the root portion is gradually pulled out through controlled orthodontic traction after wire fixation; second, the crown portion is removed separately through minimal surgery. This segmentation allows the root to be extracted along its long axis without damaging surrounding nerves or creating large bone cavities, while the crown removal is minimized to only what is necessary. The wire fixation device enables this segmented approach by providing secure attachment for gradual traction forces.

Inventive Principle:
Principle #1Segmentation
