Asymmetric Implantation Driver for Dental Fixture Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical tools lack the functionality to accurately identify and align the position and direction of a fixture during implantation in a jawbone, leading to difficulties in achieving precise alignment according to pre-set coordinates.
Innovation Solution
A surgical tool set for implantation that includes an implantation driver with radially disposed supporting portions and a recognition portion to identify the alignment position and direction of the fixture, along with a sleeve to guide the fixture into the jawbone.

Engineering Contradiction Analysis
1Measurement precision
If existing surgical tools are used for fixture implantation, then the implantation procedure can be performed, but the alignment precision and positioning accuracy of the fixture cannot be ensured
Solution Approach 1:
The implantation driver incorporates asymmetric supporting portions (first and second supporting portions with different sizes or configurations) that correspond to asymmetric alignment marks on the fixture. This asymmetric design enables the tool to uniquely identify and align with the specific orientation of the fixture, ensuring precise positioning and rotational alignment during implantation.
Solution Approach 2:
The alignment marks on the fixture serve as intermediary reference elements that mediate between the surgical tool and the fixture. These marks provide visual or physical indicators that enable the practitioner to accurately align the implantation driver with the fixture before implantation, bridging the gap between tool operation and precise fixture positioning.
2Manufacturing precision
If the implantation driver has multiple supporting portions for alignment, then the alignment accuracy improves, but the device complexity increases
Solution Approach 1:
The implantation driver is segmented into distinct functional components: multiple supporting portions (first and second supporting portions) that can be independently designed and positioned. This segmentation allows each supporting portion to be optimized for specific alignment functions while maintaining overall tool manageability and operational simplicity.
Solution Approach 2:
Different supporting portions are designed with different local characteristics (sizes, shapes, positions) to match specific alignment marks on the fixture. The first supporting portion may correspond to a first alignment mark while the second supporting portion corresponds to a second alignment mark, with each having optimized local geometry for its specific alignment function.

AI summary
Disclosed herein a surgical tool set for implant having an implantation driver for implanting a fixture. The implantation driver comprising: a first supporting portion disposed radially in an engagement portion that transmits implantation torque to the fixture; and at least one second supporting portion that is disposed radially in the engagement portion so as to be spacedly apart from the first supporting portion and is arranged asymmetrically with respect to a center point located on a central axis of the implantation driver. The second supporting portion has a larger size than the first supporting portion along at least one of an outer circumference direction and a radial direction of the engagement portion.
