Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current diagnostic methods for periodontal and peri-implant diseases are inadequate for early detection and prediction, as they often rely on measuring active MMP-8 levels rather than its activation process, which is crucial for predicting tissue degradation and inflammation, and are not suitable for chair-side diagnostics or stable biological sample analysis.

Innovation Solution

A method for detecting MMP-8 activation products, specifically the MMP-8 middle-part activation product of 10-35 kDa, which enhances the detection of active MMP-8 and its predictive power by using immunoassays and other detection technologies, allowing for early prediction of disease progression and risk assessment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If current diagnostic methods measure active MMP-8 levels, then detection is possible, but early detection and prediction capability is insufficient

Engineering Contradiction:

Improvedetection capabilityVSAvoidearly detection and prediction capability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The invention segments the MMP-8 protein into its activation product fragments (specifically the middle-part activation product of 10-35 kDa) rather than measuring intact active MMP-8. This segmentation enables detection of the activation process itself, providing earlier and more reliable prediction of tissue degradation before visible disease signs appear.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention detects MMP-8 activation products as a preliminary indicator of disease progression. By measuring the activation process rather than just active enzyme levels, the method provides advance warning of tissue degradation, enabling preventive intervention before clinical symptoms manifest.

Inventive Principle:

Principle #10Preliminary action

2Ease of manufacture

If diagnostic methods focus on active MMP-8 levels, then measurement is straightforward, but chair-side diagnostic suitability is limited

Engineering Contradiction:

Improvemeasurement simplicityVSAvoidchair-side diagnostic suitability

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The invention changes the measurement parameter from intact active MMP-8 levels to MMP-8 activation product fragments (10-35 kDa middle-part activation product). This parameter change enables the use of immunoassays and other detection technologies that are suitable for chair-side diagnostics, making the test more accessible and operationally simple while maintaining diagnostic accuracy.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If diagnostic methods use conventional approaches, then implementation is established, but diagnostic sensitivity and specificity are insufficient

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The invention extracts and specifically detects the middle-part activation product fragment (10-35 kDa) of MMP-8 from the complex biological sample. This extraction approach isolates the most informative component for disease prediction, significantly enhancing diagnostic sensitivity and specificity compared to conventional methods that measure total active MMP-8.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces conventional measurement approaches with immunoassays and other detection technologies that specifically target MMP-8 activation products. This substitution provides higher diagnostic precision through antibody-based detection methods that can distinguish activation products from intact enzyme, enabling more accurate early disease detection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
