Dental Implant Connection With Multi-Section Screw For Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant systems face limitations in achieving optimal parallelism and alignment between implants due to non-parallelism issues, requiring additional components for angle correction and lacking a single connection solution that prevents unscrewing, especially for single tooth applications.
Innovation Solution
A dental implant connection featuring three external sections on the endosseous screw, including a torx-like anti-rotation section, a first cone section with a low inclination angle for single tooth coupling, and a second cone section with a higher inclination angle for multiple implant coupling, allowing versatile coupling without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If additional components are installed to correct angles and achieve parallelism between implants, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The connection element is divided into three distinct external sections with different geometric functions: a first section for angular correction, a second section for parallelism adjustment, and a third section for prosthetic coupling. This segmentation allows each section to perform its specific function independently, achieving precise alignment without requiring multiple separate components.
Solution Approach 2:
The connection element integrates multiple functions into a single component: it provides angular correction, parallelism adjustment, and prosthetic coupling capabilities all in one element. This multi-functional design eliminates the need for additional separate components while maintaining alignment precision.
2Adaptability or versatility
If a single connection solution is used for both single tooth and multiple implant applications, then adaptability is improved, but coupling reliability deteriorates
Solution Approach 1:
Different sections of the connection element have specialized geometric properties optimized for specific functions. The first and second sections have specific angular configurations for correction purposes, while the third section has geometry optimized for secure prosthetic coupling. This local optimization ensures that each part performs its function reliably while the whole system remains adaptable.
3Reliability
If multiple separate components are used for angle correction and coupling, then coupling reliability is improved, but vertical encumbrance increases
Solution Approach 1:
The invention merges angle correction functionality and prosthetic coupling functionality into a single integrated connection element. By combining what would traditionally require separate components into one element, the vertical space requirement is reduced while maintaining the reliability of both functions through its multi-section design.
