Intended Use

EzOrtho is a software indicated for use by dentists who provide orthodontic treatment for image analysis, simulation, profilogram, VTO/STO and patient consultation. Results produced by the software's diagnostic, treatment planning and simulation tools are dependent on the interpretation of trained and licensed practitioners or dentists.

Device Story

EzOrtho is a 2D orthodontic analysis software for dentists; manages patient records and images; imports images from scanners or other imaging software (e.g., EzDenti). Features include landmark tracing, profilograms, superimposition, and VTO/STO simulation; assists in treatment planning and patient consultation via visual morphing and comparison tools. Operates on standard IBM-compatible PCs; provides diagnostic support; results require interpretation by licensed practitioners. Benefits include streamlined orthodontic workflow, improved patient communication, and automated cephalometric landmark identification to assist clinical decision-making.

Clinical Evidence

Bench testing only. Software verification and validation testing, including measurement accuracy tests, were performed to confirm performance, functionality, and reliability. The device met all pre-determined pass/fail criteria.

Technological Characteristics

Software-only device; no patient contact. Runs on IBM-compatible PC/network; supports Windows 7, 8, 10. Compatible with DICOM, BMP, JPG, PNG, TIF formats. Features include cephalometric tracing, implant simulation, and image measurement (linear/angle). Includes automated cephalometric landmark detection.

Indications for Use

Indicated for use by dentists providing orthodontic treatment for image analysis, simulation, profilogram, VTO/STO, and patient consultation. Results require interpretation by trained/licensed practitioners.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management.

and records of each patient.

EzOrtho is designed to provide a simple and straightforward user interface.

- Managing Patients and Registering Images EzOrtho offers powerful features related to making schedules and managing patient appointments. In addition, EzOrtho enables you to import images from EzDenti(K190087, K172364, K163533, K161117, K150747), Explorer, or a scanner and easily calibrate the size of the image or arrange multiple film/photo images.
- . Analyzing and Tracing Images The Landmark Voice Guide and the improved Landmark Input Interface support more accurate and easier tracing.
- . Establishing Treatment Plans The Morphing feature enables you to predict how the treatment plan established may affect the face of a patient. In addition, the Compare feature enables you to establish a treatment plan by comparing photos before and after the treatment.
- . Assisting with Patient Consultation EzOrtho provides features to facilitate understanding and communication between doctors and patients during consultation. For example, the Superimposition feature displays the changes visually due to the treatment and the Gallery feature plays a slide show with multiple images of patients.

The EzOrtho v1.0 described in this 510(k) has the same indications for use and the same technical characteristics as the OrthoVision v2.1(K173094).

{6}------------------------------------------------

The EzOrtho v1.0 are substantially equivalent to the predicate device, having the same indications for use and functionalities like operation software, computer platform, picture archiving and communication format, image format, image processing features, windowing, image edit, measurements and manipulation.

The difference between the subject device and the predicate device is the UVUX design, and also some of the additional functions have been removed from the subject device such as gallery, ceph growth projections, and some of the annotation features. It has been found that these functions and features are not really used by users so we decided to remove them to improve usability for ease of use. We believe this difference does not raise a question in substantial equivalence, because these features are merely additional and does not affect the device to achieve the intended use. The other difference is that an automatic cephalometric tracing feature is added to the subject device. With this function, the SW automatically input the cephalometric landmarks for user convenience. The users can still adjust the points manually when necessary. We performed the validation test to evaluate the accuracy of this auto feature.

Based on the results of software validation and performance tests, we conclude that the subject device is substantially equivalent to the predicate device.

#### 11. Technological Characteristics:

EzOrtho is a software device that does not contact the patient, nor does it control any life sustaining devices. Results produced by the software's diagnostic, treatment planning tools are dependent on the interpretation of trained and licensed radiologists, clinicians and referring physicians as an adjunctive to standard radiology practices for diagnosis.

#### 12. Performance Data:

SW verification/validation and the measurement accuracy test were conducted to establish the performance, functionality and reliability characteristics of the modified devices. The device passed all of the tests based on pre-determined Pass/Fail criteria.

#### 13. Conclusion:

The subject device is substantially equivalent in the areas of technical characteristics, general function, application, and indications for use. The new device does not introduce a fundamentally new scientific technology, and the device has been validated through system level test. Therefore, we conclude that the subject device described in this submission is substantially equivalent to the predicate device.
