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

VSEngineering 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

Engineering Contradiction:
Improveabutment manufacturing simplicityVSAvoidbacterial penetration and accumulation
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

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

Inventive Principle:
Principle #3Local quality

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

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the abutment has a fixed configuration, then the structure is simpler, but it cannot accommodate varying gum heights and angulations

Engineering Contradiction:
Improveabutment structure simplicityVSAvoidaccommodation of gum heights and angulations
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If additional elements are added to compensate for angulation and gum height, then adaptability improves, but device complexity increases

Engineering Contradiction:
Improveangulation and height adjustment capabilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)
