Intended Use

PREXION3D ECLIPSE is intended to produce two-dimensional digital panoramic and cephalometric images, and three-dimensional digital x-ray images of the dento-maxillo-facial region at the direction of healthcare professionals as diagnostic support.

Device Story

PreXion 3D Eclipse is a dental X-ray system for 2D panoramic, 2D cephalometric, and 3D cone beam computed tomography (CBCT) imaging. System comprises a scanner, console computer, and software (Console and Viewer). During operation, X-rays generated from a tube head pass through the patient's dento-maxillo-facial region; a flat panel detector captures the absorption data. Firmware and console software process these signals to reconstruct 2D and 3D digital images. Used in clinical settings by dentists, physicians, or X-ray technologists. Healthcare providers use the viewer software to analyze images, perform edits (e.g., cross-section views), and output results for diagnostic support. The device aids in visualizing hard tissue, supporting clinical decision-making for dental and maxillofacial diagnosis.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included Modulation-Transfer Function (MTF) per IEC 61223-3-5 to evaluate spatial resolution, artifact analysis comparing images to the FINECUBE predicate, and software validation per FDA guidance. Electrical and radiation safety confirmed via IEC 60601 series standards.

Technological Characteristics

Computed tomography X-ray system using a flat panel detector (FPD). X-ray generation: 50-90kV, 1-4mA (CT), 0.2mm focal spot. Connectivity: Console computer with proprietary software. Imaging modes: CT, panoramic, cephalometric. Software validation performed. Standards: IEC 60601-1, 60601-1-1, 60601-1-2, 60601-1-3, 60601-2-7, 60601-2-28, 60601-2-32, IEC 60825-1 (laser safety), IEC 61223-3-5 (MTF).

Indications for Use

Indicated for pediatric and adult patients requiring 2D panoramic, 2D cephalometric, or 3D digital X-ray imaging of the dento-maxillo-facial region for diagnostic support by healthcare professionals.

Regulatory Classification

| K063622 | FINECUBE | OAS |
| K103659 | CS 9300 | OAS |
| K111231 | PANOURA 18S | MUH |

The predicate devices are hereinafter called "the FINECUBE (k063622)", "CS 9300 (K103659), or "the PANOURA 18S (k111231)" in this application.

#### f. Description of the device

The PREXION3D ECLIPSE consists of scanner and two software including Console software, and Viewer software used for the Image Analysis System and Data processing. A qualified computer named Console computer is distributed with the PREXION3D ECLIPSE.

The PREXION3D ECLIPSE uses the Image Analysis System and the processed data acquired by the scanner to analyze 2D and 3D images, perform image edition, such as creating cross-section views, and output results to a printer or other output device.

During scanning, X-rays are generated from the X-ray tube head mounted in the arm of the scanner and the X-rays passing through a patient are then detected by the flat panel detector of the scanner under the control of the firmware and the Console software installed on the qualified computer. The detected X-ray absorption data is processed by the Console software and viewer software on each computer to reconstruct images. Scanning is performed using X-ray penetration signals of a patient taken from multiple directions to produce two-dimensional and three-dimensional digital X-ray images of the dento-maxillo-facial region for the diagnosis of hard tissue

The PREXION3D ECLIPSE performs three types of scanning including CT scan generating two (2) or three (3) dimensional images, Panoramic scan generating two (2) dimensional images and Cephalometric radiography generating a plain radiographic image.

#### Indications for Use g.

PREXION3D ECLIPSE is intended to produce two-dimensional digital panoramic and cephalometric images, and three-dimensional digital X-ray images of the dento-maxillo-facial region at the direction of healthcare professionals as diagnostic support.

### h. Statement of substantial equivalence

The PREXION3D ECLIPSE was developed from the FINECUBE (k063622) by adding panoramic scan function and cephalometric radiography. Following characteristics of the PREXION3D ECLIPSE are identical or similar to those of the FINECUBE (k063622);

The PREXION3D ECLIPSE has the similar characteristics to CS 9300 (k103659) regarding X-ray generation features including tube current and focal spot size, X-ray image capturing features including type of detector and pixel numbers.

The intended use of the PREXION3D ECLIPSE is identical to part of intended use of the CS 9300 (k103659), and similar to the intended use of the FINECUBE (k063622). .

The fundamental technology of cephalometric radiography of the PREXION3D ECLIPSE is identical to that of the PANOURA 18S (k111231). The PREXION3D ECLIPSE has the similar characteristic regarding X-ray generation features including tube current and focal spot size. The X-ray image capturing device of the PREXION3D ECUPSE is different from that of the PANOURA 18S (k111231).

In order to ensure same performance characteristics as predicate devices, software validation, performance testing, and risk analysis were performed. Such test results and risk analysis indicate that the PREXION3D ECLIPSE meets the requirements of the recognized consensus or voluntary standard. Based on the information presented above we conclude that the PREXION3D ECLIPSE is substantially equivalent to the predicate devices and does not raise any new questions regarding safety or effectiveness.

#### i. Risk Analysis

The PREXION3D ECLIPSE was evaluated in accordance with ISO14971:2007. The risk management of the device was deemed satisfactory.

### k. Bench Testing

THE YOSHIDA DENTAL MFG. Co., LTD has performed bench tests to ensure safety and effectiveness as follows:

### 1. Laser Safety

The laser system of the PREXION3D ECLIPSE is identical to that of the PANOURA 18S (KI11231). Therefore, the test report for IEC 60825-1 for the PANOURA 18S (K111231) is used as the test report for the PREXION3D ECLIPSE.

### 2. Modulation-Transfer Function

In order to evaluate the spatial resolution of the PREXION3D ECLIPSE, we measured the MTF in accordance with IEC 61223-3-5. The spatial resolution of all scan modes met the acceptance criteria.

### 3. Artifact Analysis

In order to evaluate the artifact of the image of the PREXION3D ECLIPSE, the images of all scan mode of the PREXION3D ECLIPSE were compared to those of the FINECUBE (K063622). There was no difference of pattern and strength of the metal artifact between the PREXION3D ECLIPSE and the FINECUBE(K063622).

The software of the PREXION3D ECLIPSE has been validated according to "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices."

EMC, Electric safety, and X-ray radiation safety are confirmed in accordance with IEC60601-1, IEC 60601-1-1, IEC 60601-1-2, IEC 60601-1-3, IEC 60601-2-7, IEC 60601-2-28. and IEC 60601-2-32.

#### 1. Conclusion

The PREXION3D ECLIPSE has similar intended use and technical characteristics to the predicate devices including the FINECUBE (k063622), CS 9300 (k103659), and the PANOURA 18S (K111231). A number of test results and risk analysis indicate that the PREXION3D ECLIPSE meets the requirements of the recognized consensus or voluntary standard. Based on those information, we conclude that the PREXION3D ECLIPSE is substantially equivalent to the predicate devices and does not raise any new questions regarding safety or effectiveness.
