Fixation Cylinder Sealing for Dental Prosthesis Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for converting removable dental prostheses into fixed prostheses are laborious, costly, and risky, involving small parts that can be lost or swallowed, and lack precise drilling guides, posing safety concerns for both professionals and patients.
Innovation Solution
A system using fixation cylinders with sealing components that temporarily attach to dental implants, allowing conversion through resin application and subsequent extraction of the sealing component, followed by fixation screws, ensuring safety and precision without small parts handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods using small parts (pins, clips, O-rings) are used to attach the prosthesis to implants, then the prosthesis can be fixed to the implants, but the risk of losing or swallowing small parts increases and the procedure becomes more complex
Solution Approach 1:
The invention extracts the sealing function from separate small components (gaskets, O-rings) and integrates it directly into the fixation cylinder structure. The cylinder itself forms a seal against the implant abutment surface, eliminating the need for separate sealing elements that could be lost or swallowed during the procedure.
Solution Approach 2:
The invention merges multiple functions into a single integrated component - the fixation cylinder combines attachment, sealing, and alignment functions in one piece. This eliminates the need for multiple separate parts (pins, clips, gaskets) that must be handled individually, thereby reducing complexity and safety risks.
2Manufacturing precision
If precise drilling guides are not used during conversion, then the procedure is simpler and faster, but alignment problems occur that can make prosthesis use unfeasible
Solution Approach 1:
The invention incorporates preliminary alignment features directly into the fixation cylinder design - guide pins and self-centering mechanisms are built into the cylinder structure itself. This allows the cylinder to automatically align with the implant abutment during insertion, eliminating the need for separate drilling guide devices while ensuring precise alignment.
3Reliability
If multiple small components are used in the conversion system, then the system can achieve proper fixation and sealing, but the number of elements increases making the procedure more laborious and expensive
Solution Approach 1:
The invention merges fixation, sealing, and alignment functions into a single integrated cylinder component. This eliminates the need for multiple separate elements (fixation pins, gaskets, O-rings, clips) while maintaining all necessary functions, thereby reducing both the number of components and procedural complexity.
Solution Approach 2:
The fixation cylinder is designed as a multi-functional component that simultaneously provides mechanical fixation to the implant abutment, creates a seal to prevent resin leakage, and guides drilling alignment. This universal design replaces multiple specialized components with one versatile element.
