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.
Innovation Solution
A method utilizing geometric dental guides and a fixation base, which is attached to the jawbone, provides precise reference points for installing a multi-tooth prosthesis in a single session, involving tools like a mouthpiece, abutment guide base, and drill guide to facilitate the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing methods for installing multi-tooth prostheses are used, then the installation can be completed with conventional tools and procedures, but the procedure requires multiple sessions and considerable time for completion
Solution Approach 1:
The fixation base is designed and fabricated in advance based on patient-specific anatomical data obtained through imaging. This preliminary preparation allows the base to be custom-fitted to the patient's jawbone geometry before the installation procedure, enabling precise positioning and reducing procedure time when the actual installation occurs.
Solution Approach 2:
The installation system is divided into modular components: the fixation base that attaches to the jawbone, removable dental guides that attach to the fixation base, and the prosthesis itself. This segmentation allows each component to be optimized independently and enables the procedure to be completed in a single session by systematically installing each module in sequence.
2Loss of time
If conventional installation methods are used, then standard tools can be employed, but the procedure is time-consuming and requires multiple sessions
Solution Approach 1:
The fixation base serves as an intermediary device that bridges the patient's jawbone and the removable dental guides. By providing a stable, custom-fitted intermediate structure, the system enables precise and rapid positioning of subsequent components, significantly reducing the time required for the installation procedure while maintaining simplicity in implementation.
3Manufacturing precision
If geometric dental guides and fixation base are used, then precise reference points and single-session installation are achieved, but specialized tools and planning are required
Solution Approach 1:
The fixation base and dental guides incorporate patient-specific anatomical features and geometric reference points that are unique to each patient's jawbone structure. This local customization ensures high geometric accuracy for each individual case while the modular design keeps the overall system manageable and not excessively complex.

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.
