Implant Abutment Outer Ring for Bacterial Barrier and Angulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental implants face issues with bacterial accumulation and penetration at the bone boundary, leading to inflammation and potential loss, due to the smooth surface of existing structural elements, and the need for adaptable angulation and gum height compensation.
Innovation Solution
The use of structural elements with an outer ring that ensures the biological width and allows for angled configurations, reducing bacterial penetration and accommodating varying gum heights and angulations without additional elements, thereby enhancing implant stability and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smooth surface is used for the abutment, then manufacturing is easier and the surface is simpler, but bacterial accumulation and penetration increase leading to inflammation and implant loss
Solution Approach 1:
The patent applies different surface qualities to different regions of the abutment. The outer ring portion has a specific surface structure that differs from the smooth inner surface, creating localized properties to prevent bacterial accumulation at critical interfaces while maintaining manufacturing simplicity overall
Solution Approach 2:
The abutment is divided into distinct functional segments: an inner smooth surface portion and an outer ring portion with different surface characteristics. This segmentation allows each portion to be optimized for its specific function - the inner portion for ease of manufacture and the outer portion for bacterial resistance
2Device complexity
If the abutment has a fixed configuration, then the structure is simpler, but it cannot accommodate varying gum heights and angulations
Solution Approach 1:
The abutment incorporates adjustable elements that allow it to adapt to different gum heights and angulations. The outer ring can be positioned at different heights and angles relative to the implant body, enabling the structure to dynamically accommodate various anatomical conditions while maintaining overall structural simplicity
Solution Approach 2:
The abutment design serves multiple functions through a single integrated structure: it provides mechanical connection, accommodates varying gum heights, adjusts to different angulations, and prevents bacterial penetration. This multi-functionality reduces the need for multiple separate components
3Adaptability or versatility
If additional elements are added to compensate for angulation and gum height, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single abutment component. The outer ring integration into the abutment body merges the functions of height adjustment, angulation compensation, and bacterial barrier into one element, eliminating the need for separate adjustment components and reducing overall device complexity
