Conductive Dental Bleaching Gel for Faster Whitening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental bleaching methods are uncomfortable, time-consuming, and can cause irritation due to the need for prolonged use of bleaching agents, with existing compositions lacking sufficient electrical conductivity to effectively accelerate the bleaching process.
Innovation Solution
A dental bleaching gel composition with hydrogen peroxide, carbamide peroxide, or sodium perborate, cross-linked polyacrylate polymer, glycerine, and alkali nitrates or hydroxides, providing electrical conductivity of at least 250 microsiemens/cm, activated by a micro-current to accelerate the bleaching reaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the concentration of peroxide is increased to shorten treatment time, then bleaching efficiency is improved, but irritation and damage to gums and lips increases
Solution Approach 1:
The patent changes the chemical parameters of the bleaching composition by incorporating specific additives (potassium nitrate, fluoride compounds, and chelating agents) that modify the behavior of peroxide on tooth surfaces. These parameter changes allow effective bleaching at lower peroxide concentrations, reducing tissue irritation while maintaining productivity.
Solution Approach 2:
The invention creates a composite bleaching gel formulation that combines peroxide with multiple protective and enhancing ingredients. This composite material approach allows the system to achieve high bleaching efficiency through synergistic effects while the protective components minimize harm to soft tissues.
2Productivity
If treatment time is extended to achieve better whitening results, then bleaching effectiveness is improved, but patient comfort and freedom of movement deteriorates
Solution Approach 1:
The patent modifies the kinetic parameters of the bleaching reaction through additives that accelerate peroxide decomposition and oxygen release. This allows achieving the same whitening effectiveness in shorter time periods, improving patient comfort while maintaining productivity.
Solution Approach 2:
The invention introduces intermediary substances (chelating agents and catalysts) that mediate the bleaching process by enhancing peroxide activity and stabilizing the reaction. These intermediaries enable faster action without requiring extended treatment times, resolving the contradiction between effectiveness and comfort.
3Device complexity
If traditional bleaching compositions are used, then formulation simplicity is maintained, but electrical conductivity is insufficient to accelerate the bleaching process
Solution Approach 1:
The patent changes the electrical parameters of the gel formulation by incorporating ionic compounds (potassium nitrate and fluoride sources) that significantly enhance electrical conductivity. This allows the use of electrical current to accelerate the bleaching process while maintaining relative formulation simplicity through the use of common dental ingredients.
