Intended Use

PaX-Duo3D Plus is a computed tomography x-ray system intended to take panoramic and cross-sectional images of the oral and craniofacial anatomy to provide diagnostic information for adult and pediatric patients. The device is operated and used by physicians, dentists, dental assistants, x-ray technicians and other professionals who are licensed by the law of the State in which he or she practices to use the device.

Device Story

PaX-Duo3D Plus is a dental radiographic imaging system providing panoramic and cone beam computed tomography (CBCT) modes. It utilizes an X-ray tube, generator, and CMOS digital X-ray detector to capture 3D images of oral anatomy. Operated by licensed professionals (physicians, dentists, technicians) in clinical settings, the device aids in dental treatments such as oral surgery and implants. The system transforms X-ray inputs into diagnostic images, which are reviewed by healthcare providers to inform clinical decision-making and treatment planning. The device supports multiple imaging volumes and resolutions via interchangeable sensors.

Clinical Evidence

No clinical trials were performed. Evidence consists of non-clinical performance testing, including electrical, mechanical, and environmental safety (IEC 60601 series), EMC testing (IEC 60601-1-2), and image quality assessment. Acceptance testing was conducted per IEC 61223-3-4 and IEC 61223-3-5. Expert review of image comparisons between the subject and predicate devices was used to support equivalence.

Technological Characteristics

Dental CBCT and panoramic system using CMOS photodiode array detectors. Tube voltage: 50-90 kV; Tube current: 2-10 mA; Focal spot: 0.5 mm; Total filtration: 2.8 mmAl.

#### Dear Mr. Kim:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of

{7}------------------------------------------------

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number [phone] or [phone] or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
