Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic intraoral force modules for correcting Class II and Class III malocclusions have limitations in terms of aesthetics, comfort, and effectiveness, as they can be bulky and may not provide sufficient corrective forces efficiently.
Innovation Solution
The development of orthodontic force module assemblies comprising a hollow outer body, a plunger, a spring, and a push rod, which work together to provide adjustable and expandable forces for tooth alignment, featuring a telescopic configuration and various attachment mechanisms for secure attachment to orthodontic brackets and archwires, ensuring comfort and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional headgear is used for Class II and Class III correction, then corrective forces can be applied, but the device becomes bulky and aesthetically objectionable
Solution Approach 1:
The force module is divided into multiple components including a connector, outer body, plunger, spring, and push rod that can be assembled separately and then integrated into a compact intraoral device, reducing overall size while maintaining force application capability
Solution Approach 2:
The plunger is slidably positioned within the outer body, and the spring is positioned within the hollow interior of the outer body, creating a nested configuration that minimizes the device's external dimensions while preserving the mechanical force generation system
2Volume of moving object
If existing intraoral force modules are used, then aesthetics are improved compared to headgear, but the devices may still be bulky and provide insufficient corrective forces
Solution Approach 1:
The spring-loaded plunger mechanism provides dynamically adjustable corrective forces that can be modified by changing the spring compression or replacing springs with different force characteristics, enabling sufficient corrective force from a compact device
Solution Approach 2:
The force module utilizes the periodic compression and expansion of the spring as the plunger moves, creating continuous periodic force application that enhances the effectiveness of corrective forces over time
3Stability of the object's composition
If fixed force modules are used, then they remain in place during treatment, but they cannot be removed or adjusted by the patient
Solution Approach 1:
The connector acts as an intermediary component that selectively couples the force module to the buccal tube through a latch mechanism, allowing the device to be securely attached during treatment yet easily removed when needed by releasing the latch
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 solution provides a more effective and comfortable means of correcting Class II and Class III malocclusions by offering adjustable forces and secure attachment, enhancing the efficiency of tooth alignment and occlusion correction while minimizing tissue damage and aesthetic concerns.
Implementation Method 1
a spring (such as a compressible coil spring, elastomeric device, or biasing member) that, when assembled during use, resists proximal movement of the plunger relative to the outer body

AI summary
Orthodontic force modules and assemblies for use in correcting class II and/or class III malocclusions include an elongate hollow outer body extending between proximal and distal ends, a plunger, spring, and push rod. The plunger and push rod are slidably received within different ends of the hollow outer body. The spring is positioned within the hollow outer body and provides an expansion force which provides a desired corrective force. The outer body, plunger, spring, and push rod can be configured in a telescoping relationship in order for the components to be telescopically compressed and expanded during use. The distal end can include a bendable pin or latch mechanism for attachment to a buccal tube. The push rod can include a hook, hole, or slot for attachment to an archwire. Various connectors for coupling an orthodontic force module to a buccal tube portion of a molar bracket are also disclosed.
