Dental Fixation Base and Guides for Single-Session Prosthesis Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing multi-tooth prostheses anchored in implants are complex and time-consuming, requiring multiple sessions and extensive procedures.
Innovation Solution
A method utilizing geometric dental guides and a fixation base, which includes a mouthpiece and abutment guide base, allows for the installation of a multi-tooth prosthesis in a single session by providing precise reference points and guiding tools for implant placement, bone recontouring, and prosthesis integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing methods are used for installing multi-tooth prostheses, then the installation can be completed with conventional procedures, but the procedure is complex and requires considerable time for completion
Solution Approach 1:
The installation procedure is segmented into distinct functional components: a fixation base that attaches to the jawbone, a mouthpiece that conforms to oral structures, and a prosthesis with teeth. Each component has a specific function and can be independently positioned and secured, streamlining the overall installation process while maintaining precision.
Solution Approach 2:
The fixation base and mouthpiece are designed and prepared in advance based on geometric dental guides and patient anatomy images. The fixation base is pre-configured with attachment structures, and the mouthpiece is pre-formed to match the patient's oral structures, allowing for rapid installation without complex intra-procedural adjustments.
2Loss of time
If existing methods are used for installing multi-tooth prostheses, then conventional installation procedures can be followed, but the procedure requires multiple sessions and extensive time
Solution Approach 1:
The fixation base attachment procedure and the prosthesis installation procedure are merged into a single integrated process. The fixation base remains in place on the dental anatomy throughout the entire procedure, serving as a stable platform for all subsequent steps including mouthpiece attachment, tooth removal, bone recontouring, and prosthesis placement, eliminating the need for multiple sessions.
3Manufacturing precision
If geometric dental guides and fixation base are used, then precise reference points and alignment are achieved, but the device structure becomes more complex
Solution Approach 1:
The fixation base serves multiple functions: it attaches to the jawbone, provides geometric reference points, supports the mouthpiece, guides bone recontouring, and anchors the prosthesis. This multi-functionality reduces the need for separate specialized devices for each step, maintaining precision while managing overall device complexity.
Solution Approach 2:
The fixation base acts as an intermediary between the jawbone and the prosthesis, providing a stable intermediate platform that ensures precise alignment. The mouthpiece serves as another intermediary, conforming to oral structures and facilitating the attachment of the fixation base while protecting soft tissues during the procedure.

AI summary
Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.
