Smart Dental Light Patterning for Soft Tissue Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tooth whitening methods using high concentrations of hydrogen peroxide with light assistance pose risks to soft tissue, requiring careful regulation and professional application to avoid damage, while existing methods like peroxide gel strips are cumbersome and less effective.
Innovation Solution
A smart lighting system that includes a light-generating unit, light-patterning unit, mouth imaging unit, and image processing and control unit, which adjusts the light pattern based on mouth images to ensure high-intensity light is applied only to the teeth, avoiding soft tissue and allowing high concentrations of bleaching agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high concentration hydrogen peroxide gel is applied with light assistance, then whitening effectiveness is improved, but soft tissue damage risk increases
Solution Approach 1:
The patent applies light only to specific tooth areas rather than the entire mouth, concentrating energy where needed. The light source is positioned to illuminate only the tooth surface with whitening gel, leaving soft tissues in shadow and thus protected from light-induced damage while maintaining high whitening effectiveness.
Solution Approach 2:
The patent introduces a physical barrier (hand, finger, or protective shield) between the light source and soft tissues. This intermediary blocks light from reaching gums and other soft tissues while allowing the light to pass through and activate the whitening gel on tooth surfaces, thus resolving the contradiction between effective whitening and tissue protection.
2Object-affected harmful factors
If peroxide gel strips are used, then soft tissue protection is improved, but application convenience deteriorates
Solution Approach 1:
The patent extracts the light application function from the strip itself and uses an external light source. Instead of incorporating light-generating elements into the strip (which would complicate the device), the system uses a separate, simple light source that can be easily positioned and controlled, thereby maintaining soft tissue protection while greatly improving application convenience.
Solution Approach 2:
The whitening gel on tooth surfaces serves as its own barrier to soft tissues. The gel itself acts as the protective layer that prevents both peroxide and light from reaching soft tissues, eliminating the need for additional protective strips or barriers and simplifying the overall application process.
3Area of stationary object
If light is applied to entire mouth area, then whitening coverage is improved, but soft tissue exposure increases
Solution Approach 1:
The patent directs light energy specifically to tooth surfaces where whitening gel is applied, rather than illuminating the entire mouth area. This localized approach ensures that light activates the bleaching agent effectively on teeth while keeping soft tissues in shadow and thus protected from light-induced damage.
Solution Approach 2:
The patent segments the mouth area into treated zones (tooth surfaces with gel) and protected zones (soft tissues). By controlling light distribution to match this segmentation, the system applies light only where needed for whitening while deliberately excluding soft tissues from light exposure, thus resolving the contradiction between coverage and protection.
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 system effectively whitens teeth by applying high-intensity light only to the teeth, reducing the risk of soft tissue damage and enhancing the bleaching process, making it safer and more efficient than conventional methods.
Implementation Method 1
a light-generating unit (1)... adapted so as to allow the image processing and control unit to adjust the light-patterning unit on the basis of information obtained from the mouth image sensing unit, prior to allowing the light-generating unit to emit light of the desired high intensity
Implementation Method 2
exposing the cured whitening varnish composition to light to accelerate the bleaching process

AI summary
A smart lighting system for applying light to teeth in the context of tooth whitening and teeth that have been provided with a light-curable whitening varnish. The system includes a light-generating unit, a light-patterning unit, a mouth imaging unit, a mouth image sensing unit, and an image processing and control unit, and is adapted so as to allow the image processing and control unit to adjust the light-patterning unit on the basis of information obtained from the mouth image sensing unit. By doing so, prior to allowing the light-generating unit to emit light, it can be ensured that light emitted to assist tooth whitening, does not affect soft tissue.
