Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic devices face limitations in precise bracket positioning, predictable biomechanics, and aesthetics due to manual placement errors and the need for separate bracket components, leading to unintended tooth movements and extended treatment times.
Innovation Solution
An automated system that produces a one-piece orthodontic jig and brackets using computer-controlled manufacturing techniques, such as 3D printing, directly from a CAD model, allowing for precise positioning and detachment of brackets during bonding, eliminating manual placement errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual bracket positioning is used, then the process is simple and flexible, but positioning precision deteriorates leading to placement errors
Solution Approach 1:
The system performs preliminary digital planning and design of bracket positions using CAD software before actual bonding. The prescription is created in advance with precise coordinate specifications, and the positioning device is pre-configured based on these digital plans, eliminating manual positioning errors during the bonding procedure itself.
Solution Approach 2:
A specialized positioning device acts as an intermediary between the digital prescription and the physical bracket placement. This device includes registration components that interface with anatomical landmarks and positioning mechanisms that transfer the prescribed coordinates to the actual bracket positions, serving as a mechanical mediator that ensures precision.
2Productivity
If separate bracket components are used, then the design is flexible and adaptable, but the bonding process time increases due to manual placement
Solution Approach 1:
The positioning device is segmented into distinct functional components: registration components that interface with anatomical landmarks, positioning mechanisms that hold multiple brackets, and transfer mechanisms. This segmentation allows each component to perform its specific function efficiently while working together as an integrated system.
Solution Approach 2:
Multiple brackets are pre-positioned on the positioning device according to the prescription before the bonding procedure begins. This preliminary arrangement allows the clinician to transfer all brackets in a single efficient operation rather than placing them individually during the bonding appointment, significantly reducing treatment time.
3Manufacturing precision
If conventional bonding trays are used, then the process is straightforward, but bracket positioning accuracy deteriorates due to manual errors
Solution Approach 1:
The positioning device serves as a mechanical intermediary that translates digital prescription data into precise physical bracket positions. It includes registration features that interface with anatomical landmarks and positioning mechanisms that ensure accurate placement, acting as a bridge between the digital plan and physical execution.
Solution Approach 2:
The system replaces manual visual estimation and hand-positioning with a mechanical positioning system based on registered anatomical landmarks and prescribed coordinates. The device mechanically ensures that brackets are placed at the exact positions specified in the digital prescription, eliminating human error in manual positioning.
4Adaptability or versatility
If multiple separate components are used for jig and brackets, then each component can be optimized independently, but the overall system complexity increases
Solution Approach 1:
The patent integrates the positioning device and bracket holding mechanisms into a single unified apparatus. The positioning device incorporates registration components, positioning mechanisms, and bracket holders as integrated elements, reducing the number of separate components while maintaining the ability to customize for different patient requirements through digital design.
Solution Approach 2:
The positioning device is designed with universal features that allow it to accommodate different bracket types and tooth configurations. The registration components can interface with various anatomical landmarks, and the positioning mechanisms can be adjusted for different prescription requirements, providing multi-functionality without requiring multiple specialized devices.

AI summary
A method for producing a one-piece orthodontic jig and attachments employs a computer-aided design (CAD) system to create a model of a patient's dental anatomy. A set of orthodontic attachments and their desired positions are also designed in the CAD model. An orthodontic jig for temporarily positioning the attachments during the bonding process is then designed that includes features for registering the jig to selected teeth, together with connecting members that detachably connect the attachments to the jig and hold the attachments in their desired position on the patient's teeth during the bonding process. The orthodontic jig and attachments is fabricated as a single piece by computer-controlled manufacturing (e.g., 3D printing) based on the CAD model.
