Vibrating Orthodontic Strip for Accelerated Tooth Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic treatments are lengthy, uncomfortable, and have low compliance due to the use of static forces, with limitations in treating complex malocclusions, and existing vibrating devices are not suitable for human use, requiring further development for effective and efficient orthodontic remodeling.
Innovation Solution
A low-cost, peel-and-stick vibrating orthodontic appliance with a flexible strip design that can be applied to existing devices or directly to teeth, featuring small vibratory sources, optional on/off switches, and programmable controllers to optimize vibration frequency and duration, providing consistent and efficient force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If static mechanical forces are used to induce bone remodeling, then teeth can be moved, but treatment takes about twenty-four months on average
Solution Approach 1:
The patent applies mechanical vibration at frequencies between 1-100 Hz to accelerate bone remodeling and tooth movement. The vibrating device creates oscillatory mechanical forces that stimulate osteoclast and osteoblast activity, significantly reducing treatment time from 24 months to potentially 6-12 months while maintaining safe force levels on the teeth.
Solution Approach 2:
The invention uses periodic vibration cycles rather than continuous static force. The device delivers controlled vibrational bursts (e.g., 5-20 minutes per day) that create repeated mechanical stimulation to bone and periodontal tissues, enhancing remodeling efficiency without requiring constant force application.
2Productivity
If increased force is applied to shorten treatment time, then tooth movement accelerates, but pain and root resorption risk increase
Solution Approach 1:
The vibrating device distributes mechanical energy through oscillatory motion rather than concentrated static force. This creates micro-stresses throughout the periodontal ligament and bone that stimulate remodeling without exceeding pain thresholds or causing root damage, enabling faster movement with safer force distribution.
Solution Approach 2:
The invention changes the physical parameters of force application by using high-frequency oscillation at low amplitude rather than low-frequency static force at high magnitude. This parameter transformation allows accelerated tooth movement while maintaining forces within safe biological limits, avoiding pain and root resorption.
3Reliability
If traditional orthodontic braces are used, then malocclusion can be treated, but the appliances are uncomfortable and perceived as unaesthetic
Solution Approach 1:
The vibrating device serves as an intermediary component that can be integrated with various orthodontic appliances (braces, aligners, retainers). This separate vibration module enhances treatment effectiveness without requiring modification of the primary orthodontic appliance, maintaining aesthetic appearance while adding functional benefits.
Solution Approach 2:
The invention replaces part of the mechanical force system with vibrational energy. Instead of relying solely on continuous mechanical pressure from braces or aligners, the vibrating device adds oscillatory stimulation that accelerates tooth movement, potentially allowing for lighter continuous forces and improved patient comfort.
4Manufacturing precision
If 24-month treatment duration is required, then thorough orthodontic correction is achieved, but patient compliance deteriorates due to long treatment time
Solution Approach 1:
The vibrating device is designed for periodic use (e.g., 5-20 minutes daily) rather than continuous operation. This intermittent vibration protocol maintains treatment effectiveness while significantly improving compliance, as patients can easily incorporate short vibration sessions into their daily routine without the burden of 24-month continuous appliance wear.
Solution Approach 2:
By adding vibrational acceleration to the treatment protocol, the overall treatment duration is reduced from 24 months to potentially 6-12 months. This time reduction dramatically improves patient compliance while maintaining thorough orthodontic correction, as patients are more motivated to complete shorter treatment courses.
