Two-Step Tooth Remineralization via Peroxide Conditioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tooth whitening and orthodontic treatments often result in enamel demineralization and weakening, which can be exacerbated by the natural oral environment's variability in mineral availability and interference from bacteria, with existing methods lacking control over remineralization and repair.
Innovation Solution
A two-step method and kit comprising a conditioning composition with a peroxide agent to prepare the enamel surface, followed by a remineralizing composition containing calcium or fluoride ions, applied in close succession to intentionally and selectively remineralize teeth, ensuring controlled ion concentration and timing for enhanced enamel strength and decay resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If peroxide bleaching is used to whiten teeth, then tooth whitening is achieved, but enamel surface morphology and hardness are negatively affected due to demineralization
Solution Approach 1:
The patent applies a conditioning composition containing peroxide to the tooth surface before applying the remineralizing composition. This preliminary conditioning action prepares the enamel surface by controlling demineralization, creating optimal conditions for subsequent remineralization and ensuring the enamel is ready to receive and retain the remineralizing ions effectively
Solution Approach 2:
The patent converts the harmful effect of peroxide-induced demineralization into a beneficial process by immediately following with a remineralizing composition. The controlled demineralization from the conditioning step creates space for remineralizing ions to deposit, transforming the harmful demineralization effect into a controlled remineralization process that strengthens the enamel
2Reliability
If natural oral environment is relied upon for enamel repair, then fluoride and mineral ions are provided, but the process is uncertain and variable due to interference from other materials and ions in saliva
Solution Approach 1:
The patent introduces a controlled remineralizing composition as an intermediary substance that delivers specific mineral ions (calcium, fluoride, phosphate) to the enamel surface. This intermediary composition ensures consistent and reliable ion delivery, bypassing the variability and interference present in natural saliva, thereby achieving consistent and predictable enamel repair
Solution Approach 2:
The patent changes the parameters of the oral environment by applying a formulated remineralizing composition with controlled concentrations of mineral ions. This alters the chemical environment from the natural, variable saliva composition to a controlled, optimized ion delivery system, ensuring consistent and reliable remineralization regardless of individual saliva variations
3Productivity
If orthodontic appliances are placed on teeth for extended periods, then orthodontic treatment is achieved, but enamel demineralization and weakening occur due to difficulty in maintaining oral hygiene
Solution Approach 1:
The patent applies the conditioning composition before the remineralizing composition, creating a preliminary prepared state of the enamel surface. This preliminary action ensures that the enamel is optimally prepared to receive and retain remineralizing ions, which is particularly important for areas with orthodontic appliances where natural cleaning is difficult
Solution Approach 2:
The patent establishes a continuous remineralization process by applying both conditioning and remineralizing compositions in sequence, ensuring uninterrupted ion delivery to the enamel surface. This continuous action prevents the enamel from remaining in a weakened state during orthodontic treatment, maintaining enamel strength throughout the treatment period
4Duration of action of stationary object
If remineralization is allowed to occur naturally over weeks, then enamel recovery happens, but the process is slow and uncontrolled
Solution Approach 1:
The patent changes the parameters of the remineralization process by applying a formulated composition with optimized concentrations and combinations of mineral ions (calcium, fluoride, phosphate). This alters the natural slow remineralization process into an accelerated, controlled process that occurs much faster while maintaining high productivity and effectiveness
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
This approach accelerates and improves enamel remineralization, providing stronger and more resilient teeth by controlling the remineralization process, especially during and after orthodontic treatment or tooth whitening, compared to natural repair mechanisms.
Implementation Method 1
The conditioning composition includes a conditioning agent, for example, a peroxide component configured to clean and prepare the enamel and/or dentin tooth exterior surface for remineralization
Implementation Method 2
at least the remineralizing composition advantageously includes a remineralizing ion comprising at least one of calcium or fluoride

AI summary
Methods for use in selectively conditioning and remineralizing teeth. An exemplary method comprises the steps of applying a conditioning composition to one or more of a person's teeth, and separately applying a remineralizing composition to the person's teeth. The conditioning composition includes a conditioning agent, and the remineralizing composition includes a remineralizing agent comprising calcium ions and/or fluoride ions. The conditioning composition may be applied prior to or after application of the remineralizing composition. In one embodiment, both the conditioning composition and the remineralizing composition include different remineralizing ions (e.g., one including calcium, one including fluoride).
