Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for gum diseases such as gingivitis, periodontitis, and peri-implantitis do not effectively combine long-lasting antibacterial effects with tissue regeneration, leading to inefficient treatment outcomes.
Innovation Solution
A composition comprising hyaluronic acid or a pharmaceutically acceptable salt thereof, combined with one or more inorganic peroxides such as calcium peroxide (CaO2), zinc peroxide (ZnO2), and magnesium peroxide (MgO2), which releases oxygen over a prolonged period, enhancing antibacterial activity while promoting tissue regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a burst release of oxygen is used for antibacterial defense, then oxygen radicals are produced to fight microorganisms, but tissue damage occurs due to health-threatening radicals
Solution Approach 1:
The patent transforms the burst release mechanism into a periodic, controlled oxygen release system. The composition releases oxygen in sustained, moderate amounts over time rather than in a single high-concentration burst, maintaining antibacterial effectiveness while avoiding tissue damage from excessive radicals
Solution Approach 2:
The patent changes the concentration parameter of oxygen release from high (burst) to low/moderate (sustained). By controlling the release rate and maintaining oxygen concentration within a specific range, the composition achieves continued antibacterial activity without reaching the threshold that causes tissue damage
2Productivity
If high doses of zinc peroxide are used to accelerate wound healing, then wound healing is promoted, but cytotoxic effects occur
Solution Approach 1:
The patent applies parameter changes by controlling the concentration of zinc peroxide within a specific range (0.01-10% w/w). This optimized concentration range maintains the wound healing acceleration effect while staying below the threshold that triggers cytotoxic effects on surrounding tissues
Solution Approach 2:
The patent implements continuous, low-dose zinc peroxide release rather than high-dose intermittent application. The sustained release at controlled concentrations provides continuous wound healing promotion without allowing accumulation to toxic levels
3Quantity of substance
If high doses of calcium peroxide are used to increase oxygen supply, then oxygen availability is improved, but calcium deposits form in tissues causing damage
Solution Approach 1:
The patent controls the calcium peroxide concentration (0.01-10% w/w) and release rate to provide sufficient oxygen for wound healing while preventing excessive calcium accumulation. The sustained low-dose release avoids the threshold for pathological calcium deposition in elastic tissues
4Reliability
If conventional treatments are used for gum diseases, then some symptomatic relief is achieved, but long-lasting antibacterial effects with tissue regeneration are not combined
Solution Approach 1:
The patent merges previously separate treatment goals into a single composition that simultaneously provides long-lasting antibacterial effects and promotes tissue regeneration. The combination of zinc peroxide, calcium peroxide, and hyaluronic acid creates synergistic effects where antibacterial action and regenerative support occur together
Solution Approach 2:
The patent creates a multi-functional composition where a single formulation performs multiple functions: antibacterial defense, wound healing acceleration, tissue regeneration support, and oxygen supply. This universal composition replaces the need for multiple separate treatments
Applied Scientific Principles
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 combination of hyaluronic acid and inorganic peroxides significantly increases the availability of oxygen, providing a sustained antibacterial effect that is less harmful to tissues, thus improving the efficacy of treatments for gum diseases and supporting tissue regeneration.
Implementation Method 1
a composition comprising hyaluronic acid or a pharmaceutically acceptable salt thereof, and one or more inorganic peroxides selected from the group consisting of calcium peroxide (CaO2), zinc peroxide (ZnO2) and magnesium peroxide (MgO2) for use in wound healing
Implementation Method 2
the combination of hyaluronic acid and inorganic peroxides significantly increases the availability of oxygen, providing a sustained antibacterial effect

AI summary
Many next-generation biomaterials will need the ability to not only promote healthy tissue integration but to simultaneously resist bacterial colonization and resulting biomaterials-associated infection. For this purpose, antimicrobial nanofibers of polycaprolactone (PCL) were fabricated by incorporating calcium peroxide. PCL nanofibers containing different ratios of calcium peroxide (1%, 5% and 10% (w/w)) with or without ascorbic acid were fabricated using an electrospinning technique. Antimicrobial evaluations confirmed the inhibitory properties of the nanofibers on the growth of E. coli and S. epidemidis because of a significant burst release of calcium peroxide from the nanofibers. Analysis of tissue cell response showed that despite an initial toxic effect over the first 24 h, after 4 days of culture, osteoblast viability and morphology were both healthy. These results demonstrate that oxygen-generating nanofibers can be designed and developed to provide a short-term peroxide-based antimicrobial response while still maintaining attractive tissue-integration properties.
