Integrated Scan Body Element for Dental Implant Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scan body elements for dental implants suffer from poor precision in orientation determination, leading to imprecise fitting of dental bridges or bars, which can cause health issues and additional costs due to manual errors during scanning.
Innovation Solution
A scan body element with a top part made of non-metal materials like polymer or ceramic, a lower part made of metal, and a central part with a threaded portion and screw driver recess, allowing precise orientation and easy mounting on dental implants or analogs, reducing the risk of errors and improving inter-oral scanning precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a polymeric cap is manually positioned and pressed onto a base part screwed onto the implant, then the scan body element can be assembled, but the precision in determining the tilt angle of the implant deteriorates
Solution Approach 1:
The invention merges the base part and the cap into a single integrated scan body element that is directly screwed onto the implant. This eliminates the separate assembly steps of manually positioning and pressing a cap onto a base part, thereby removing the cumulative errors that occur during manual assembly and directly improving tilt angle determination precision.
Solution Approach 2:
The scan body element is designed as a self-contained unit with integrated threading and geometric features. The element serves its own assembly function by being directly screwed onto the implant without requiring separate components or manual adjustment steps, thereby ensuring precise orientation from the outset.
2Adaptability or versatility
If multiple parts are fastened individually on the implant, then the scan body element can be assembled, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The invention combines multiple functional parts (base part, cap, and scan features) into a single integrated scan body element. This eliminates the need to fasten multiple components individually onto the implant, thereby significantly reducing assembly time and simplifying the clinical procedure while maintaining all necessary functions.
Solution Approach 2:
The scan body element is designed as a universal component that performs multiple functions: it provides structural support for scanning, enables direct screwing onto the implant, and incorporates geometric features for optical recognition. This multi-functionality in a single element eliminates the need for separate assembly steps for each function.
3Ease of operation
If a scan body element with integrated threading is used, then the mounting process is simplified, but the manufacturing complexity increases
Solution Approach 1:
The invention integrates the threading structure, cap features, and scan body geometry into a single monolithic component. While this increases manufacturing complexity compared to separate parts, it dramatically simplifies the mounting process by eliminating multiple assembly steps. The integrated design ensures precise orientation and tilt angle determination from the moment of screwing onto the implant.

AI summary
A scan body element is configured to be inserted in a dental implant or implant analog for scanning with or in an optical scanning system. The scan body element has a top part with at least one geometric feature recognizable via scanning. A metallic lower part is shaped to fit to a dental implant or an analog, and fixed to the top part. A central part is arranged inside the lower part, and includes a threaded portion and a recess for receiving a screw driver through a hole in the top part. The recess allows the threaded portion to be turned relative to the lower part to fasten the scan body element to the implant or the analog. The central part is configured to be interlocked between the lower part and the top part such that the scan body element is arranged as a single element.
