Solution Overview

Problem

Current dental prosthetic devices require invasive procedures that expose the bone to external environments, leading to infection risks and aesthetic issues, and do not allow for adjustment or modification of the prosthesis during installation, especially when the intraosseous implant is installed at an angle or sub-crestally.

Innovation Solution

A dental prosthetic device with an axial-symmetric intraosseous implant and an intermediate connection component featuring a conical and threaded design, allowing for rapid change between installation configurations, protecting the interface zone from contamination, and enabling adjustable height and prosthetic approach without immediate load, promoting tissue regeneration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the second component is connected directly to the intraosseous implant after osseointegration, then the dental prosthesis can be installed, but the gingival part and bone part must be lacerated which exposes the bone to external environment and causes infection risks

Engineering Contradiction:

Improveease of connectionVSAvoidinfection risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a third component as an intermediary element between the intraosseous implant and the second component. This third component remains covered by the gingival tissue while the second component is connected to it, thereby avoiding the need to lacerate the gingiva and exposing the bone. The intermediary component acts as a mediator that enables the connection process without creating harmful exposure to the external environment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Shape

If the second component has limited height to remain covered by gingival part, then aesthetic requirements are satisfied, but the inclination of the dental prosthesis cannot be adjusted if the intraosseous implant is installed inclined

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidadjustability of prosthesis inclination

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The patent divides the connection system into three separate components: the intraosseous implant, the third intermediary component, and the second component. This segmentation allows the third component to remain short and covered by gingiva for aesthetic purposes, while the second component can be adjusted for inclination. The functional requirements are distributed across different components, enabling both aesthetic appearance and adjustability to be satisfied simultaneously.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the interface zone between implant and abutment is completely exposed toward the outside, then the connection is accessible for installation, but infiltration and infections can occur

Engineering Contradiction:

Improveaccessibility for installationVSAvoidinfection and infiltration

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The third component serves as an intermediary that protects the interface zone between the implant and the external environment. It provides a covered pathway that allows the second component to be connected to the implant without exposing the critical interface zone to external contamination. The intermediary component maintains a sealed environment for the implant-abutment interface while still enabling installation procedures.

Inventive Principle:

Principle #24Intermediary (Mediator)
