Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic treatment methods require time-consuming and invasive preparation of teeth with acid etching, leading to demineralization, discomfort, and complications during bonding and debonding of orthodontic devices.
Innovation Solution
An orthodontic adhesive system using engineered marine mussel proteins with catechol moieties that facilitate bonding without etching, allowing for reversible and easy debonding through light exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If acid etching is used to prepare tooth surface for bonding, then bonding strength is improved, but tooth demineralization and patient discomfort increase
Solution Approach 1:
The patent extracts and eliminates the acid etching step from the traditional bonding process by using a self-etching adhesive system that achieves bonding without removing enamel minerals, thereby maintaining tooth integrity while providing sufficient adhesion strength
Solution Approach 2:
The patent changes the chemical parameters of the adhesive system by incorporating specific acidic components with controlled pH and concentration that can etch and bond simultaneously, transforming the separate etching and bonding steps into a unified process that minimizes enamel damage
2Reliability
If multiple preparation steps (cleaning, etching, sealing) are performed, then bonding reliability is improved, but chair time increases
Solution Approach 1:
The patent merges the cleaning, etching, and bonding steps into a single integrated application where the self-etching adhesive performs multiple functions simultaneously, dramatically reducing chair time while maintaining bonding reliability through the coordinated action of its multifunctional components
Solution Approach 2:
The adhesive system is designed with multi-functionality, where a single product serves as cleaner, etchant, and bonding agent, eliminating the need for multiple separate steps and materials while ensuring reliable adhesion through its comprehensive functional design
3Strength
If conventional adhesive systems are used, then bonding is achieved, but debonding leaves residue requiring mechanical removal
Solution Approach 1:
The patent introduces dynamic properties to the adhesive system through light-responsive components that allow the bond to be strongly formed during treatment but easily and cleanly released upon light exposure during debonding, eliminating the need for mechanical scraping and ensuring complete removal without residue

AI summary
An orthodontic adhesive includes components capable of allowing easy debonding of an orthodontic device from a patient's tooth. The adhesive includes an engineered marine mussel protein. The adhesive may include at least one photocleavable moiety. The adhesive is applied in one or more individual layers. One of the components of the adhesive is capable of binding to a tooth and the other component may be capable of binding to an orthodontic device. A method of adhering an orthodontic device to a tooth includes applying a layer of an orthodontic adhesive to either the tooth or the orthodontic device or the tooth and the orthodontic device and affixing the orthodontic device to the tooth with the orthodontic adhesive situated between the tooth and the orthodontic device. The engineered marine mussel protein includes one or more catechol moieties or one or more derivatives of a catechol moiety.
