Dental Implant Removal Forceps With Thread-Engaging Holding Pieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current forceps for removing dental implant fixtures are ineffective due to insufficient frictional force, causing the holding portions to slip out of the fixture, and existing removal kits are expensive and not widely usable.
Innovation Solution
Design of forceps with pinching portions featuring holding pieces that protrude to match the outer circumference of the fixture, including grooves and inclined surfaces to securely engage with the threaded portion, preventing slipping during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If forceps for removing teeth are used to remove the fixture, then the existing tool can be utilized, but the holding portions slip out of the fixture due to insufficient frictional force
Solution Approach 1:
The forceps design modifies only the holding portions with thread-engaging structures (protrusions and grooves) while keeping the rest of the forceps structure standard. This localized modification enables fixture removal functionality without requiring complete redesign, maintaining reusability while solving the slipping problem through enhanced local engagement with the fixture threads
2Reliability
If a removal kit is used to remove the fixture, then reliable removal can be achieved, but the high cost and disposable nature make it difficult to widely use
Solution Approach 1:
The forceps are designed to be self-retaining through the interaction between the holding portion protrusions and the fixture threads. The groove geometry and protrusion shape create automatic engagement and locking mechanisms that do not require additional components or disposable elements, enabling reliable removal while maintaining reusability and reducing cost
Solution Approach 2:
The forceps are designed to perform multiple functions: standard tooth removal and fixture removal. By incorporating the thread-engaging holding portions into reusable forceps, the tool can serve both traditional dental applications and implant removal, eliminating the need for separate expensive disposable kits
3Adaptability or versatility
If the holding portions have standard tooth-grasping structure, then the forceps can be used for natural teeth, but the structure cannot securely hold the threaded fixture
Solution Approach 1:
The forceps design modifies only the holding portions with thread-engaging structures (protrusions and grooves) while keeping the rest of the forceps structure standard. This localized modification enables fixture removal functionality without requiring complete redesign, maintaining reusability while solving the slipping problem through enhanced local engagement with the fixture threads
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
The forceps effectively secure the dental implant fixture by enhancing the frictional contact with the threaded portion, preventing slipping and ensuring successful removal without the need for expensive removal kits.
Implementation Method 1
enhancing the frictional contact with the threaded portion, preventing slipping

AI summary
An object of the present invention is to provide forceps for removing a dental implant fixture, in which pinching portions securely hold a fixture to remove the fixture implanted in an alveolar bone, and thus to prevent the pinching portions from slipping out of the fixture. Forceps for removing a dental implant fixture according to the exemplary embodiment of the present invention include: a pair of handles; coupling portions extended from the handles, crossed, and hingedly coupled; pinching portions connected to the coupling portions; and holding pieces protruding from ends of the pinching portions in a direction toward a center of a dental implant fixture and each having an arc corresponding to at least a part of an outer circumference of the fixture so that the holding pieces are inserted into a trough of a threaded portion formed on the outer circumference of the fixture.
