Intended Use

The ScanX Touch/ScanX Duo Touch is intended to be used for scanning and processing digital images exposed on Phosphor Storage Plates (PSPs) in dental applications.

Device Story

ScanX Touch/ScanX Duo Touch is a dental imaging system that processes photostimulable phosphor storage plates (PSPs) previously exposed to X-rays. The device uses a laser (approx. 650 nm) to scan the plates, converting latent X-ray images into digital data via a photomultiplier tube. An internal RFID system identifies plates. The device features an in-line eraser for immediate plate reuse. It operates as a standalone unit or connected to a PC, allowing temporary internal storage if the network is unavailable. A 7.0-inch touch screen provides job management and image previews. Clinicians or authorized technicians use the device to digitize radiographs, which are then transferred to office software (e.g., DBSWIN) for display, storage, and diagnostic review. By providing rapid digital conversion, the device facilitates efficient dental workflows and diagnostic decision-making.

Clinical Evidence

No clinical performance testing was required. Substantial equivalence was established through bench testing, including electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), laser safety (IEC 60825-1), and image performance metrics (MTF, DQE per IEC 62220-1). A licensed dentist performed a comparative evaluation of test images against the predicate, confirming diagnostic utility and equivalence.

Technological Characteristics

Extraoral source x-ray system (Class II, MUH). Uses laser scanning (650 nm) and photomultiplier tube for image acquisition. 16-bit image depth. Includes RFID/NFC plate identification. Features in-line plate eraser. 7.0-inch touch screen interface. Connectivity via PC/network. Power: 100-240VAC, 50/60 Hz. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60825-1, and FCC Part 15.

Indications for Use

Indicated for scanning and processing digital images exposed on Phosphor Storage Plates (PSPs) in dental applications for patients requiring intraoral X-ray imaging.

Regulatory Classification

Identification

An extraoral source x-ray system is an AC-powered device that produces x-rays and is intended for dental radiographic examination and diagnosis of diseases of the teeth, jaw, and oral structures. The x-ray source (a tube) is located outside the mouth. This generic type of device may include patient and equipment supports and component parts.

- 5. Device Description: The ScanX Touch is a device that scans photostimulable phosphor storage plates that have been exposed in place of X-ray film and allows the resulting images to be displayed on a personal computer monitor and stored for later recovery. It will be used by licensed clinicians and authorized technicians for this purpose. Two models are available: The

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

Scanx® Touch processes one imaging plate while ScanX® Duo Touch processes two at a time. The ScanX Touch also includes an RFID Phosphor Plate identification system which requires that the Phosphor Plate has an RFID tag attached to the non-imaging side of the Plate. ScanX allows multi room dental clinics to produce digital radiographs within seconds using a flexible PSP (Phosphor Storage Plates). The workflow is supported by a touch screen, for job handling (ScanManager, Patient information), preview and standalone work. ScanX produces the digital diagnostic quality intraoral image by scanning PSPs, which have been exposed to X-rays. ScanX can also work independently. If the IT network goes down, the user can still scan and save X-ray images. The images are temporarily placed in the internal memory and are later transferred to the office database. This makes the device ideally suited to provide a mobile solution when it is necessary to visit the patient outside the office. Additionally, ScanX allows computer storage, processing, retrieval and display of the processed images utilizing a user supplied software (e.g. DBSWIN) and computer. An additional feature of ScanX consists of an in-line plate eraser function that removes the latent image from the plate immediately after scanning. This design provides an efficient one-operation scanning and erasing process leaving the user with a PSP ready for the next X-ray procedure

- 6. Indications for use: (Rx Only) The ScanX Touch/ScanX Duo Touch is intended to be used for scanning and processing digital images exposed on Phosphor Storage Plates (PSPs) in dental applications.
- 7. Safety and Effectiveness:

The ScanX Touch is a device that scans photostimulable phosphor storage plates that have been exposed in place of X-ray film and allows the resulting images to be displayed on a personal computer monitor. Safety concerns associated with the ScanX Touch were addressed by safety testing the device with UL to IEC 60601-1 third edition (Electrical Safety), IEC 60601-1-2 (EMC) and IEC 60825-1 (Laser Safety). Design changes and risks associated with the introduction of the ScanX Touch / ScanX Duo Touch were properly mitigated by Air Techniques' cGMP compliant Quality Management System, change control processes, risk assessments, and product validation. The ScanX Touch contains a Class 1 Laser Device as defined by 21 CFR 1040.10. Installation and operation manuals are provided with instructions for safe use and servicing of the ScanX Touch. The ScanX Touch is a non-patient contact Class II medical device.

- 8. Substantial Equivalence to Predicate Device Summary
Air Techniques' ScanX Touch is identical in function and intended use to the ScanX Intraoral View manufactured by Duerr Dental AG, whose dental units are in commercial distribution and are FDA cleared under 510K # K170733. The same engineering principles are used in both devices. ScanX Touch and the ScanX Intraoral View (predicate) both capture, digitize, and process intraoral X-ray images that are stored in imaging plate recording media.

- 10. Summary of non-clinical performance testing: Prior to performance testing, labeling was developed to mitigate cybersecurity risks and risks to pediatric patients. The following guidance documents were consulted: Content of Premarket Submissions for Management of Cybersecurity in Medical Devices, Guidance for Industry and Food and Drug Administration Staff OCTOBER 2014 and Pediatric Information for X-ray Imaging Device Premarket Notifications Guidance for Industry and Food and Drug Administration Staff NOVEMBER 2017. Risk analysis and software validation was successfully performed. EMC Testing according to IEC 60601-1-2 was successfully performed. Electrical safety testing according to IEC 60601-1 was successfully performed. Laser safety testing was performed according to IEC IEC 60825-1, Safety of laser products. The unit is UL listed. MTF and DQE image performance testing was performed with reference to IEC 62220-1:2003. Noise power spectrum measurements were documented. These FDA guidance documents were employed: Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices, Document issued on: May 11, 2005 AND Guidance for the Submission of 510(k)s for Solid State X-ray Imaging Devices, Guidance for Industry and Food and Drug Administration Staff Document issued on: September 1, 2016. The device was also tested by UL for compliance with FCC Part 15 subpart C. The testing was successful. This was required because of the internal RFID feature. The device contains an NFC radio used for RFID. Test images were acquired on the new device and

{8}------------------------------------------------

on the predicate device. They were presented to a licensed dentist for his professional evaluation. The following questions were answered in the affirmative:

The images acquired using the ScanX Duo Touch displayed in the dental imaging software are representative of customary intraoral X-rays.

The images acquired using the ScanX Duo Touch are useful for a diagnostic purpose.

The images acquired using the ScanX Duo Touch do not display any misleading artifacts that would hinder my ability to diagnose from.

The images acquired using the ScanX Duo Touch are comparable to those images acquired using the ScanX Intraoral View.

- 11. Summary of clinical performance testing: Not required to establish substantial equivalence.
- 12. Conclusion: In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification, Air Techniques, Inc. concludes that the ScanX Touch is safe and effective and substantially equivalent to the predicate device as described herein.
