Triangular Truss Palatal Anchorage for Orthodontic Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing palatal anchorage devices for orthodontic treatment lack sufficient support against pulling forces, are bulky and uncomfortable, and have complex structures that complicate fitting and production, leading to discomfort and inefficiency in orthodontic procedures.
Innovation Solution
A palatal anchorage device with a triangular truss structure and screw fixation parts on each vertex, combined with a 3D printing method for custom production based on patient-specific scans, reducing size, weight, and production time, and enhancing support force against elastic body pulling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional palatal anchorage device is used, then the device can be fixed to the palate, but it lacks sufficient support against pulling forces from the elastic body
Solution Approach 1:
The palatal anchorage device is divided into multiple triangular truss structures that work together to provide support. Each triangle is formed by three support members (first, second, and third support members) that are fixed at different locations on the palate, creating a segmented framework that distributes and resists pulling forces effectively.
Solution Approach 2:
The device utilizes triangular geometric shapes (not spherical, but triangular) to provide structural strength. The triangular configuration of support members creates a rigid truss structure that is inherently resistant to deformation and pulling forces, with each triangle forming a stable geometric unit that maintains its shape under load.
2Strength
If the palatal anchorage device structure is made more complex to improve support, then support force increases, but the device becomes bulkier and less comfortable
Solution Approach 1:
The device is segmented into multiple thin triangular truss structures rather than one bulky component. Each triangle is formed by slender support members that can be fixed at different palate locations, creating a distributed framework that provides strong support while maintaining a lightweight, compact overall volume that is comfortable for the patient.
3Productivity
If conventional palatal anchorage devices are used, then orthodontic treatment can be performed, but production time and complexity increase
Solution Approach 1:
The palatal anchorage device is designed as a universal template that can be applied to multiple patients with similar palatal anatomy. The standardized triangular truss structure with three support members provides a multi-functional solution that can be reproduced efficiently, reducing production time and complexity while maintaining effectiveness across different orthodontic treatment cases.

AI summary
A palatal anchorage device for orthodontic treatment with enhanced support is provided, which includes a body having a form of a triangular truss, screw fixation parts formed on each of three vertex regions of the body, with through-holes formed therein to allow a screw to be placed in a palate, and hook parts extending from both sides of the body and hooking and fixing an elastic body connected to a tooth fixture.
