Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic treatments for malocclusions such as cross-bite and Brodie bite are complex and often ineffective, particularly in reducing patient visits and achieving predictable treatment outcomes.
Innovation Solution
An orthodontic archwire with a unique design featuring a transverse rectangular cross-section and varying radii of curvature is used with self-ligating brackets to gently and gradually correct malocclusions, utilizing superelastic materials for faster and more predictable tooth alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional expansion devices or crossbite elastics are used to correct malocclusions, then the cross-bite can be corrected, but the treatment becomes complex and requires frequent patient visits
Solution Approach 1:
The patent combines multiple treatment functions into a single archwire design. The archwire simultaneously performs tooth alignment, arch expansion, and malocclusion correction that traditionally required separate devices like expanders and elastics, thereby simplifying the treatment system while maintaining effectiveness
Solution Approach 2:
The archwire is designed with universal applicability for treating various malocclusions including cross-bites, Brodie bites, and constricted arches. The specific geometric configuration with varying radii of curvature allows one device to address multiple orthodontic problems that previously required different specialized appliances
2Reliability
If traditional orthodontic treatments are used for malocclusions, then tooth alignment can be achieved, but treatment time is extended and patient visits are frequent
Solution Approach 1:
The patent utilizes changes in material parameters by employing superelastic materials for the archwire. This material property enables the wire to deliver consistent corrective forces over extended periods, accelerating tooth movement and reducing overall treatment time while improving predictability of outcomes
Solution Approach 2:
The archwire features a specific curved configuration with varying radii of curvature along its length. This geometric design optimizes force distribution and directs mechanical forces efficiently to produce coordinated tooth movements and arch form changes, thereby shortening treatment duration
3Ease of operation
If archwire slot is opened for inserting the archwire, then the archwire can be installed, but the archwire is free to move laterally which may reduce control
Solution Approach 1:
The archwire design incorporates localized geometric features with specific radii of curvature at different segments. This creates varying degrees of engagement with the bracket slots along the wire length, providing controlled positioning in critical areas while maintaining ease of installation, thus resolving the contradiction between operational ease and positioning precision
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 archwire provides a faster and more predictable treatment for multiple malocclusions by expanding the upper arch while maintaining optimal anterior curvature, reducing the need for frequent patient visits and enhancing treatment efficiency.
Implementation Method 1
The use of the present invention archwire formed from a superelastic material provides a faster and more predictable treatment outcome for the patient
Implementation Method 2
When a patient's teeth are incorrectly leveled and aligned, the archwire elastically deforms to engage the brackets, thereby introducing a force that urges the teeth to move to the correct position over time
