Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position capturing devices for tooth implants are complex to handle, especially in tight spaces within the mouth, making it difficult for dentists to accurately record and align the angular orientation of tooth implants for producing well-fitting dentures.
Innovation Solution
A position capturing device comprising multiple position capturing units with elongated transfer posts and a carrier unit that allows for adjustable and rotatable connection of these units, enabling simple and precise alignment of tooth implants, with the carrier unit connecting adjacent transfer posts via rotatable and adjustable fixing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a position capturing device with multiple position capturing units is used to accurately record tooth implant positions, then measurement precision is improved, but device complexity increases making it difficult to handle in tight spaces
Solution Approach 1:
The position capturing device is divided into multiple independent position capturing units, each comprising a transfer post with a shank that can be individually inserted into tooth implants. These modular units can be handled and positioned separately, reducing the complexity of manipulating a single large complex device while maintaining the ability to capture multiple positions accurately
Solution Approach 2:
The carrier unit incorporates adjustable and rotatable fixing elements that allow dynamic adaptation to different tooth implant configurations. The fixing elements can be rotated and adjusted to match various angular orientations and alignments of tooth implants, enabling the device to adapt to different anatomical situations without requiring multiple fixed-configuration devices
2Manufacturing precision
If the carrier unit has fixed distance between fixing elements, then manufacturing precision is improved, but adaptability to different tooth implant configurations decreases
Solution Approach 1:
The fixing elements on the carrier unit are designed with adjustable distances and rotatable orientations. This allows the carrier unit to adapt to different tooth implant configurations while maintaining precise positioning capability. The adjustable nature enables the same carrier unit to work with various implant arrangements without sacrificing manufacturing precision
3Measurement precision
If the position capturing device is designed for precise alignment, then measurement precision is improved, but ease of operation decreases making insertion and removal difficult
Solution Approach 1:
The device is segmented into modular position capturing units with transfer posts that can be individually inserted and removed from tooth implants. This segmentation allows for simpler, more straightforward insertion and removal operations compared to a monolithic device, while the modular units maintain precise alignment capability through their design
Solution Approach 2:
The transfer post with shank acts as an intermediary element between the tooth implant and the carrier unit. This intermediary design simplifies the connection and disconnection process, allowing for easy insertion and removal while ensuring precise alignment and positioning of the position capturing units

AI summary
A position capturing device for tooth implants in a patient's mouth includes multiple position capturing units, each with an elongated transfer post with a shank. The device includes a tooth implant interface and a bore configured to receive a tooth implant screw. The device includes a carrier unit, configured to interconnect the position capturing units, that includes a carrier element and first and second fixing elements. The first fixing element includes a fastening element configured to pivotably and lockably attach to the carrier element, a shank-receiving element with a sleeve-shaped portion configured to be plugged onto the shank, and a clamping screw connecting the fastening element and the shank-receiving element to be rotatable relative to each other. The fastening element includes a sleeve-shaped portion configured to surround the carrier element and allow a displacement of the fastening element along the carrier element.
