Dental Abutment Blank Retainer for Vibration-Free Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining devices for dental abutment blanks often damage the implant interface due to vibrations during machining, leading to inaccurate seating and potential inflammation, as they exert forces on the implant connection, which is crucial for the stability and longevity of the artificial tooth.
Innovation Solution
A holding device with a retainer section spaced apart from the implant interface, allowing the abutment blank to be held in a rotationally secure position using a form-fitting connection, preventing twisting and minimizing contact with the holding device, thus enabling precise machining without damaging the implant interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the abutment blank is held on the implant interface during machining, then the blank can be retained and machined, but vibrations occur that damage the implant interface and reduce seating accuracy
Solution Approach 1:
The holding device is divided into two distinct functional sections: a first section that holds the implant interface and a second section that holds the abutment blank. This segmentation isolates the implant interface from machining vibrations while maintaining retention, resolving the contradiction between securing the blank and protecting the interface from damage
Solution Approach 2:
The second holding section acts as an intermediary between the machining process and the implant interface. It provides the necessary retention and positioning during machining while preventing direct transmission of vibrational forces to the sensitive implant interface, thereby protecting it from damage
2Strength
If forces are exerted on the implant connection during machining, then the blank can be securely held, but the stability and longevity of the artificial tooth are compromised
Solution Approach 1:
The holding device separates the functions of retention and positioning into two distinct sections. The first section provides stable holding of the implant interface without subjecting it to machining forces, while the second section absorbs all forces and vibrations during machining, thus protecting the implant connection and ensuring long-term reliability
Solution Approach 2:
The second holding section serves as a mediator that absorbs machining forces and prevents their transmission to the implant connection. This intermediary structure maintains holding strength during machining while preserving the integrity and longevity of the implant-abutment interface
3Manufacturing precision
If the abutment blank is held in a fixed position during machining, then precise machining can be achieved, but the implant interface becomes exposed to damaging vibrations
Solution Approach 1:
The device segments the blank-holding function from the interface-holding function. The second section provides fixed positioning for machining precision while the first section isolates the implant interface from vibrational exposure, allowing both precision and protection to coexist
Solution Approach 2:
The first holding section acts as an intermediary that secures the implant interface in a stable position without transmitting machining vibrations to it. This allows the second section to provide the fixed positioning needed for precision machining while the interface remains protected from harmful vibrations

Function Achieved in This Case
This solution allows for high-precision machining of dental abutment blanks with minimal vibration, ensuring accurate seating and long-term functionality by maintaining the integrity of the implant interface, reducing the risk of bacterial infiltration and inflammation.
Implementation Method 1
The holding device has a basic body with a retaining receptacle, which retains or accommodates the abutment blank. The retaining receptacle and the abutment blank and/or its retainer section correspond to one another in such a way as to result in a form-fitting connection.
