Used in dental clinics by trained orthodontic professionals. Output consists of digital files for fabrication of appliances by third parties. Assists clinicians in diagnosis, treatment planning, and progress monitoring. Benefits include improved visualization of treatment objectives and customized appliance design.

Clinical Evidence

No clinical data. Bench testing only; software, hardware, and integration verification and validation performed per FDA guidance.

Technological Characteristics

Software-only device programmed in Delphi. Runs on Windows 7/8/10 (64-bit) with minimum 8GB RAM, Intel Core i5, and 250GB HDD. Supports DICOM, STL, JPG, BMP, PNG formats. No patient contact. Features include 2D/3D measurement, arch shape analysis, occlusion mapping, and virtual appliance design.

Indications for Use

Indicated for orthodontic patients requiring management of dental models, inspection, analysis, treatment simulation, and virtual appliance design (custom metal bands, indirect bonding transfer media) prior to, during, and at the end of orthodontic treatment.

# Primary Predicate Device

The Ortho System™ intended for dental retainers has the same intended use, scientific concept, performance specification and technical characteristics as the primary predicate device 3Shape Ortho System™ (K152086) from 3Shape A/S.

Based on the information and supporting documentation provided, the Ortho System™ and the primary predicate device (K152086) have same intended use.

Both software devices are used by Dental Professionals in orthodontic treatment planning (before, during, after treatment) covering management of patients and models, inspection, 2D and 3D measurement and orthodontic analysis of models, 2D & 3D treatment simulation, as well as virtual appliance preparation, handling and export, and they are both providing device output.

Additionally, the indirect bonding functionality of both systems is intended for use with commercially available brackets and wires.

The only modifications compared to the primary predicate device, besides look and feel of the user interface, are:

- 1. A workflow improvement to view present and ideal position of teeth at

{4}------------------------------------------------

the same time (dual view) with the introduction of arch wire in Indirect Bonding.

sshar

- 2. The ScanIt Manager is used for all scanners instead of ScanIt Orthodontics and ScanIt Ortho Impression that both are retracted.
Therefore, the Ortho System™ and the predicate (K152086) are found to be similar in their intended use, supported anatomic areas and the majority of the available features and functionalities.

# Reference Predicate devices

The Ortho System have two reference predicate devices K161884 and K163677, which uses the functions and tools of Ortho System™ to produce different orthodontic dental treatments than the primary predicate device. Both of these devices have the same fundamental scientific technology as the primary predicate device, as they are consolidated in the single medical software.

Based on the on the information and supporting documentation provided, the reference predicate devices do not alter the performance specification nor technical characteristics of the primary predicate device.

# Indications for Use

Ortho System™ is intended for use as a medical front-end device providing tools for management of orthodontic models, systematic inspection, detailed analysis, treatment simulation and virtual appliance design options (Custom Metal Bands, Export of Models, Indirect Bonding Transfer Media) 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 the Ortho System™ 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.

# Device Description

3Shape's Ortho System™ is a software system used for the management of 3D scanned orthodontic models of the patients, orthodontic diagnosis by measuring, analysing, inspecting and visualize 3D scanned orthodontic models, virtual planning of orthodontic treatments by simulating tooth movements, virtual placement of orthodontic brackets on the 3D models and design of orthodontic appliances based on 3D scanned orthodontic models, including transfer methods for indirect bonding of brackets. Output includes only Export Model (also called dental casts), Custom Metal Bands (also called metal bands), and Indirect Bonding Transfer Trays (also called orthodontic bracket placement trays). All devices are to be fabricated from FDA cleared materials by third party under the responsibility of the user.

The device has no patient contact.

{5}------------------------------------------------

## Scientific Concept

The underlying scientific concept of the Ortho System™ is to apply digital imaging tools for in orthodontic case archiving, diagnosis, treatment planning and CAD design of customized appliances.

Virtual positioning of brackets is possible with the use of encrypted libraries of the bracket geometry provided by the manufacturers and available through a dedicated download center in the software.

The system supports the following types of digital data: DICOM, STL, JPG, BMP, PNG.
