Universal One-Piece Scan Body for Dental Implant Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for registering implant position and orientation in dental impressions are inefficient, often requiring manual attachment of manufacturer-specific scan bodies and multiple components, which can lead to inaccuracies and increased complexity in 3D-scanning for dental prosthetic construction.
Innovation Solution
A universal, one-piece scan body that fits into a cavity created by an identically shaped implant position transfer body, allowing direct registration of implant orientation within a dental impression, enabling precise 3D data acquisition for prosthetic design by securely fitting into the impression and matching the implant's terminus structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual attachment of manufacturer-specific scan bodies is used, then implant position registration can be achieved, but device complexity and operation time increase
Solution Approach 1:
The patent combines the implant position transfer body and scan body into a single integrated component. The scan body is directly formed on the impression-taking surface of the transfer body, eliminating the need for separate manual attachment steps. This merging reduces device complexity while maintaining the ability to accurately register implant position and orientation through the unified structure.
Solution Approach 2:
The integrated scan body is designed with a universal configuration that can be used across different implant systems and manufacturers. The standardized terminus structure allows the same component to function as both an implant position transfer device and a scan body for multiple implant types, reducing the need for manufacturer-specific components and simplifying the overall process.
2Loss of information
If manual attachment of scan bodies is required, then implant orientation data can be captured, but operation time and process complexity increase
Solution Approach 1:
The scan body is pre-integrated onto the implant position transfer body during manufacturing, so that when the transfer body is placed on the implant and impression material is taken, the scan body is already in position. This preliminary integration eliminates the need for separate manual attachment steps during the clinical procedure, reducing operation time while ensuring accurate implant orientation data capture.
3Manufacturing precision
If multiple components are used for impression taking, then detailed implant data can be recorded, but manufacturing and operational complexity increase
Solution Approach 1:
The patent integrates the scan body directly onto the impression-taking surface of the transfer body as a single molded component. This merging eliminates the need for separate manufacturing and assembly steps for multiple components, simplifying both manufacturing processes and clinical operations while maintaining the precision needed for accurate implant position transfer.
