Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning bacterially contaminated implant surfaces, such as dental and bone implants, are ineffective in removing biofilms without damaging the implant surface and can lead to periimplantitis, which may result in tissue and bone deterioration, necessitating removal of the implant.
Innovation Solution
A treatment liquid composed of an aqueous solution of a metallic salt and acid with a conductivity of at least 30 mS/cm, preferably 75 mS/cm, is used to promote electrolytic cleaning, killing bacteria, and detaching biofilms without causing harm to the implant or surrounding tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cleaning methods are used to remove biofilm from implant surfaces, then biofilm removal efficiency is improved, but implant surface damage and tissue harm increase
Solution Approach 1:
The invention changes the chemical parameters of the cleaning solution by using a weak acid electrolyte (pH 2-4) with specific conductivity (30-200 mS/cm) to achieve effective biofilm removal while controlling the aggressiveness toward the implant surface and surrounding tissue, thus resolving the contradiction between cleaning efficiency and surface damage
Solution Approach 2:
The weak acid electrolyte acts as an intermediary substance that enables the electrolytic cleaning process to occur, facilitating biofilm removal through controlled electrochemical reactions while the acid component buffers the pH to prevent excessive tissue damage and implant surface degradation
2Reliability
If electrolytic cleaning process is applied to kill bacteria and remove biofilm, then germicidal effect is improved, but formation of toxic and bone-damaging substances increases
Solution Approach 1:
The invention controls the electrolytic process parameters by adjusting the pH to 2-4 and conductivity to 30-200 mS/cm, which optimizes the germicidal effect through electrochemical reactions while preventing the formation of excessive toxic substances by maintaining controlled reaction conditions
Solution Approach 2:
The invention converts potentially harmful strong electrolytic reactions into beneficial controlled processes by using weak acid electrolytes that provide sufficient ion concentration for effective germ killing while the acid buffering capacity prevents pH extremes that would generate toxic byproducts
3Productivity
If strong electrolytic process is used to enhance cleaning efficiency, then biofilm detachment is improved, but implant surface erosion increases
Solution Approach 1:
The invention optimizes the electrolytic cleaning parameters by setting conductivity between 30-200 mS/cm and pH between 2-4, which provides sufficient ionic strength for effective biofilm detachment while the weak acid nature and buffered pH prevent excessive surface erosion of the implant material

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The treatment liquid effectively kills bacteria and removes biofilms from implant surfaces, minimizing tissue damage and preventing periimplantitis, while ensuring the implant's integrity and functionality.
Implementation Method 1
a conductivity of at least 30 mS/cm, preferably at least 75 mS/cm, and particularly preferably at least 150 mS/cm, results
Implementation Method 2
an electrolytic process is provided, by which the ions (cations and/or anions) are conveyed by means of electrostatic forces through the biofilm
Implementation Method 3
These ions react chemically or electrochemically on the implant surface. Through these reactions, new compositions of matter are created
