Dental Implant Insertion Tool With Break Zone And Auxiliary Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion tools for dental implants can cause damage to the implant and bone if excessive torque is applied, leading to jamming or breakage, requiring replacement and additional tools for manipulation, which complicates surgical procedures.
Innovation Solution
An insertion tool with a break zone and an auxiliary torque receiving means that allows torque transmission from a drive tool to the dental implant, enabling manipulation even after breakage without replacing the tool, using identical cross-sectional contours for efficient torque transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insertion tool is designed with a break zone to prevent damage to implant and bone, then safety is improved, but the tool requires replacement after breakage which increases device complexity and surgery time
Solution Approach 1:
The insertion tool is segmented into a proximal portion and a distal portion separated by a break zone. The distal portion with the torque applying means remains in the implant after the proximal portion breaks off, allowing continued manipulation without tool replacement. This segmentation resolves the contradiction by maintaining safety through controlled breakage while eliminating the need for tool replacement.
Solution Approach 2:
The break zone is extracted as a separate functional element between the torque applying means and the torque receiving means. When excessive torque is applied, only the proximal portion containing the torque receiving means breaks off, while the distal portion with the torque applying means remains intact in the implant. This extraction allows the tool to safely break while preserving the implant manipulation capability.
2Object-affected harmful factors
If the insertion tool breaks at predetermined torque to prevent damage, then harmful factors are reduced, but additional tools are required for manipulation after breakage
Solution Approach 1:
The tool is divided into proximal and distal portions at the break zone. After breakage, the distal portion remains attached to the implant with its torque applying means intact, allowing the surgeon to continue manipulation using the same tool without requiring additional instruments. This segmentation ensures both safety and ease of operation.
Solution Approach 2:
The break zone acts as an intermediary element that selectively breaks under excessive torque while leaving the torque applying means intact. This intermediary design allows the harmful force to be absorbed at the break zone while preserving the functional interface with the implant, eliminating the need for additional manipulation tools.
3Reliability
If the insertion tool is replaced after breakage, then reliability is maintained, but surgery time increases
Solution Approach 1:
The insertion tool is segmented such that only the proximal portion breaks off while the distal portion with the torque applying means remains in the implant. This allows the surgeon to continue the procedure without replacing the tool, significantly reducing surgery time while maintaining reliability through the controlled breakage mechanism.
Solution Approach 2:
The break zone is pre-designed in the insertion tool to break at a predetermined torque level. This preliminary action of controlled breakage prevents the need for tool replacement, as the distal portion with the torque applying means remains functional in the implant. The surgeon can immediately continue manipulation without interruption, reducing surgery time while maintaining procedural reliability.
