Intended Use

The RiX70 DC is designed for the acquisition of intraoral images of the teeth, jaw and the mouth structure for diagnostic purposes.

Device Story

RiX70 DC is an extraoral dental X-ray system for intraoral imaging. Comprised of a double mobile/articulate support arm, control unit with wall plate, and tube head. Uses high-frequency, constant potential generator to produce X-rays at 70 kV and 7 mA. System automatically calculates exposure time (0.01s to 2.00s) based on selected tooth, patient size, and imaging mode; manual adjustment available. Used in dental clinics by dental professionals. Output is an X-ray beam directed at the patient's oral anatomy to capture images on film or digital sensors. Facilitates diagnostic assessment of teeth, jaw, and mouth structures. Available in wall-mount or floor-standing configurations.

Dear Joyce St. Germain:

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 mav, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be avare that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

#### Intended Use

The RiX70 DC is designed for the acquisition of intraoral images of the teeth, jaw and the mouth structure for diagnostic purposes.

#### Device Description

The subject device is RiX70 DC X-rav Unit and it is an extraoral source dental x-ray system intended for intraoral imaging. The subject device is a device comprised of a double mobile and articulate support arm. At the opposite ends of the arm are located, respectively:

- A control unit equipped with wall plate, extension arm and wired control . device.
- A tube head with x-ray tube.

X-ravs are produced using the high frequency and constant potential generators with a built in round collimator with the high frequency (HF) technology. X-rav emission at 70 kV and 7 mA (maximum power), and the xray unit automatically calculates the best exposure time (from 0.01 s to 2.00 s) based on the selected tooth and patient size, as well as an adjustable arm that allows for easy positioning. This device may also be adjusted manually to the user's specific radiographic technique.

The system can be used either with conventional film or a digital imaging system.

The RiX70 DC is available in two configurations: a wall-mount configuration and a floor-standing configuration, and provides for three selections of kVp: 60kVp, 65kVp, and 70kVp.

#### Risk Analysis Information

Risk analysis includes particular recommendations to address radiation exposure to the user under mobile operating conditions. Operators should always read the user manuals for medical devices and take the necessary precautions before using the device. Methods to reduce exposure is recommended safety precautions such as wearing personnel monitoring and protective equipment. Additional information for safety is found in the user manual for this device. Risk management was performed according to ISO 14971. This device is known as a moderate level of concern.

#### Conclusion

The subject and the predicate device have the same indications for use and the same intended use and the similar technological features. The RiX70 DC and the predicate, RX DC share the same principles of operation and use similar imaging firmware. The conclusion is that the subject device is as safe and effective as the predicate.
