Intended Use

iOrtho is intended for use as a medical front-end device providing tools for management of orthodontic cases, systematic inspection, detailed analysis, treatment simulation and virtual applians (Export of Models, Indirect Bonding Transfer Media, Sequential aligners) based on 3D models of the patient's dentition before the start of an orthodontic treatment. It can also be applied during the treatment to inspect and analyze the progress of the treatment. It can be used at the end of the treatment to evaluate if the outcome is consistent with the planned/desired treatment objectives. The use of iOrtho requires the user to have the necessary training and domain knowledge in the practice of orthodonties, as well as to have received a dedicated training in the use of the software.

Device Story

iOrtho is a standalone orthodontic software platform for dental professionals. It ingests 3D digital dental scans (STL files) to facilitate case management, diagnosis, and treatment planning. The software provides tools for auto-segmentation of gums/bone (with manual adjustment), measurement point selection, and 3D treatment simulation. It enables the design of virtual appliances, including sequential aligners and indirect bonding transfer media. The system outputs 3D models for fabrication via 3D printing. Used in clinical settings by orthodontists to monitor treatment progress and verify outcomes against planned objectives. The software aids clinical decision-making by allowing practitioners to visualize tooth movement and refine treatment plans. It benefits patients by enabling customized, precise orthodontic appliance design and progress tracking.

Clinical Evidence

No clinical data. Bench testing only. The device underwent integration, verification, and validation testing in accordance with FDA software guidance and IEC 62304 standards to confirm performance per intended use.

Technological Characteristics

Standalone software; compatible with Windows 7/Mac OS 10.12+; requires WebGL-capable video card, 2GB RAM, and internet access. Features include 3D model import (STL), auto-segmentation with manual adjustment, automated measurement point selection, and virtual appliance design. Operates via web browser (Chrome, Firefox, Safari, Edge).

Indications for Use

Indicated for orthodontic patients requiring management, inspection, analysis, treatment simulation, and virtual appliance design based on 3D dentition models. Applicable before, during, and at the end of orthodontic treatment to evaluate progress and outcomes. Requires trained orthodontic professionals.

Regulatory Classification

The Proposed Device is an orthodontic appliance design and treatment simulation software is for use by dental professionals to aid in diagnosis and design solutions for patients. Digital scans (3D) of a patient's dentition can be loaded into the software and the dental professional can then create treatment plans for each individual patient and their needs. The system can be used to fabricate 3D dental models {4}------------------------------------------------ using standard stereolithographic (STL) files for use in 3D printers. These models can then be used as a template for thermoforming aligners or retainers by Angel Align technicians. ## Indications for Use: iOrtho is intended for use as a medical front-end device providing tools for management of orthodontic cases, systematic inspection, detailed analysis, treatment simulation and virtual appliance design options (Export of Models, Indirect Bonding Transfer Media, Sequential aligners) based on 3D models of the patient's dentition before the start of an orthodontic treatment. It can also be applied during the treatment to inspect and analyze the progress of the treatment. It can be used at the end of the treatment to evaluate if the outcome is consistent with the planned/desired treatment objectives. The use of iOrtho requires the user to have the necessary training and domain knowledge in the practice of orthodontics, as well as to have received a dedicated training in the use of the software. Comparison to Predicate Devices: The Proposed Device is functionally equivalent to the following device: 3Shape A/S Ortho System (K171634, cleared Jan 17, 2018) (hereafter referred to as "Predicate Device"), and possesses minor differences to the previously cleared Reference Device to allow treating physicians include mandible repositioning and traction accessories during treatment planning and simulation. The following table demonstrates the functional specifications of the Proposed Device are substantially equivalent to the Predicate Device, minorly different to the Reference Device, and raises no new questions regarding safety and effectiveness of the device. | | Proposed Device: | Predicate Device: | Reference | Reference | | |--------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------| | Specification | iOrtho | 3Shape A/S Ortho System (K171634) | Device: Wuxi EA Medical Instruments Technologies Limited.
