Universal Dental Implant Spanner Extender With Geometry-Specific Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guided surgery methods for dental implants face challenges in accurately orienting and positioning implants due to limited visibility of the implant orientation within the mouth, necessitating separate spanner devices for different connection geometries.
Innovation Solution
A universal spanner device with distinct marks or indicators on its outer surface to identify and orient hexagonal, square, or triangular implant connections, allowing a single device to be used with various implant types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate spanner devices are used for different connection geometries (hexagonal, square, triangular), then the orientation accuracy for each specific implant type is improved, but the device complexity and the number of tools required increases
Solution Approach 1:
The spanner device is designed with a universal interface that can accommodate multiple connection geometries (hexagonal, square, triangular implants). The device incorporates multiple sets of marks corresponding to different geometries, allowing a single spanner to function with various implant types, thereby reducing the number of tools needed while maintaining orientation accuracy
Solution Approach 2:
The spanner device is segmented into functional zones with distinct mark patterns for different connection geometries. Each geometry type has its own set of reference marks and indicators, allowing the professional to select and use the appropriate marks based on the specific implant type being installed
2Stability of the object's composition
If the implant is positioned at greater depth in the jaw, then the implant stability is improved, but the visibility of the implant orientation for the professional decreases
Solution Approach 1:
The spanner device incorporates high-contrast visual marks and indicators on its outer surface that are clearly visible during the procedure. The marks use contrasting colors or patterns that stand out against the surgical field, enabling the professional to easily detect the orientation and position of the implant even when working at greater depths where direct visualization is limited
Solution Approach 2:
The spanner device acts as an intermediary tool that translates the internal orientation of the implant (which is not directly visible) into external visual signals through its mark patterns. By observing the orientation of the spanner device itself and its marks, the professional can infer the orientation of the implant without needing to directly see the implant's connection geometry
3Ease of operation
If a universal spanner device is used for multiple implant connection geometries, then the ease of operation and device portability are improved, but the precision for specific geometry identification may be reduced
Solution Approach 1:
Different regions or surfaces of the spanner device are optimized for specific functions: some areas feature high-precision mark patterns for accurate geometry identification, while other areas provide ergonomic grips and operational interfaces. Each local zone of the device has quality characteristics tailored to its specific purpose, maintaining high precision for geometry identification while ensuring ease of operation

AI summary
The invention, a spanner device for guided surgery to orient and position a dental implant and system, relates to a spanner device for guided surgery which, incorporated on an implant driver, serves to orient and position the dental implant in a patient's jaw, regardless of the connection geometry of said implant, so that the same spanner device can be used to orient different types of implant, regardless of its type of connection. The invention also relates to a system formed by the above device and a driver for the coupling thereof to a dental implant.
