Curved Vector Orthodontic Apparatus for Malocclusion Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic appliances for treating Class II and III malocclusions are costly, labor-intensive, require frequent orthodontist visits, and are prone to structural failure due to linear force applications, which can dislodge retainers and hinder treatment efficiency.
Innovation Solution
A pre-calibrated, removable orthodontic apparatus applying curved vector forces using Nickel Titanium alloy coils, which can be adjusted and repaired outside the mouth, providing a gentle and consistent 3.5 ounces of corrective pressure to treat malocclusions without the need for braces, allowing for temporary removal and reduced orthodontist visits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If linear force application is used in orthodontic appliances, then the corrective force can be applied directly, but the retainer becomes prone to dislodgement and structural failure
Solution Approach 1:
The patent applies curved vector forces instead of linear forces. The force application path is designed to follow a curved trajectory that engages the retainer along its length, distributing the corrective force and preventing dislodgement. This curvature in force application transforms the linear push that caused failure into a distributed curved load that maintains retention while providing correction.
2Manufacturing precision
If braces and archwires are used for treatment, then comprehensive tooth alignment can be achieved, but the treatment becomes costly and labor-intensive with frequent visits
Solution Approach 1:
The patent extracts the essential corrective function from the complex braces and archwire system. By removing the need for brackets, archwires, and frequent adjustments, the invention isolates the core vector force application mechanism that achieves alignment. This extraction simplifies the treatment to a single appliance wear period, eliminating the complexity of traditional orthodontic systems while maintaining alignment effectiveness.
Solution Approach 2:
The appliance is designed to be self-adjusting through its curved vector force mechanism. The pre-calibrated curved forces automatically adapt to tooth movement and maintain corrective pressure without requiring manual adjustments by an orthodontist. This self-service capability eliminates frequent visits and reduces treatment complexity while maintaining precise alignment results.
3Productivity
If frequent orthodontist visits are required for adjustments and repairs, then treatment can be optimized, but the treatment time and cost increase
Solution Approach 1:
The curved vector force appliance is pre-calibrated with the correct force magnitude and direction before being delivered to the patient. The pre-formed curved geometry ensures that the corrective forces are already optimized for the patient's specific malocclusion, eliminating the need for multiple adjustment visits. This preliminary preparation of the force system accelerates treatment efficiency while reducing time loss from frequent office visits.
4Ease of repair
If the appliance requires removal for cleaning and repair outside the mouth, then maintenance becomes easier, but the treatment continuity may be interrupted
Solution Approach 1:
The appliance is designed as a segmented system with removable components that can be easily cleaned and maintained outside the mouth. The separation of the force application mechanism from the retainer allows for independent maintenance of each component. This segmentation enables easy repair and cleaning while maintaining treatment continuity, as the appliance can be quickly reassembled and reused without interrupting the corrective force application.

AI summary
An improved dental apparatus that can treat Class II or Class III malocclusions without the need for braces, that can be repaired outside of the patient's mouth, that can be temporarily removed by the patient, that can be fitted, calibrated, set up and adjusted outside the patient's mouth prior to installation, and that is inexpensive. It utilizes universal torsion springs with accurate bending forces assembled with linear members of varying lengths to make a curved intrusive vector force device connecting teeth aligners that apply gentle constant forces to correct underbite and overbite conditions.
