Fixation Base and Abutment Guides for Single-Session Prosthesis Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental prosthesis installation methods face challenges such as inaccurate scanning in bloody environments, difficulty in aligning multiple scans, and time-consuming processes, particularly in digital workflows for full-arch restorations on implants.
Innovation Solution
A method utilizing geometric dental guides and a fixation base that provides precise reference points, allowing for the installation of a multi-tooth prosthesis in a single session, using tools like a mouthpiece, abutment guide base, and drill guide to ensure accurate implant placement and prosthesis integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple fiducial scans are captured before and after surgery, then the digital records can be registered and aligned, but the process becomes time-consuming and accuracy deteriorates in bloody environments
Solution Approach 1:
The fixation base is designed with pre-integrated fiducial markers that are positioned and configured before surgery begins. This preliminary preparation eliminates the need for multiple post-surgery scans and alignment operations, as the fiducial reference system is already in place to guide implant placement and prosthesis fabrication directly
Solution Approach 2:
The patent combines the fiducial markers, fixation base, and surgical guides into a single integrated system. This merging eliminates the need for separate scanning and alignment of multiple fiducial markers, as the integrated system provides all necessary reference information in one unified structure that remains stable throughout the surgical process
2Adaptability or versatility
If traditional multiple-session prosthesis installation is used, then complex procedures can be performed, but the treatment duration and patient inconvenience increase
Solution Approach 1:
The fixation base and surgical guides are designed and fabricated before surgery based on digital impressions and planning. This preliminary preparation enables complex prosthesis installation to be performed in a single surgical session, as all guide structures and reference systems are pre-configured for the specific patient's anatomy and treatment requirements
Solution Approach 2:
The fixation base serves multiple functions simultaneously: it provides stable anchorage for the surgical guide, incorporates fiducial markers for digital recording, guides implant placement, and enables single-session prosthesis installation. This multi-functionality consolidates what traditionally required multiple separate sessions into one comprehensive procedure

AI summary
Apparatus and method for installing a dental prosthesis to maxillary or mandibular jawbone of a patient are shown and described. The apparatus and method include a fixation base for providing an attachment surface and an abutment guide attachable to said fixation base in a position wherein the abutment guide is oriented to receive abutments and guide the abutments for placement on the implants. The abutment guide has at least one peg that is designed to be scannable by an intraoral scanner and is designed as a positioning structure that allows a dental prosthesis to be releasably attached to the abutment guide in a specific position.
