Verification activities for confirmation of the image quality of the proposed device have been performed. The results of the image quality review have demonstrated that the device is substantially equivalent to the predicate device.

The subject system Primevision 3D has fundamentally the same hardware as the predicate device, without the inclusion of a Cephalometric imaging feature for the subject device. The remote control has been updated for the subject device to include a hand switch, and the new device HMI (referred to as the "easypad" or "multipad" for prior devices) has a different appearance, yet the same core functionality, as the predicate device. The subject device HMI contains less functionality than the predicate, because some of the functionality has been moved to cloud-based software (e.g. program selection) for the subject device. The EMC testing generated substantially equivalent results results as the predicate. Bench testing for image quality has been performed and the results indicate substantial equivalence to the predicate Axeos, for both 2D and 3D imaging modes (See the tabulated values below for details).

Animal testing was not necessary for this premarket submission. Clinical testing was provided in this submission, and extraoral images were submitted along with an image evaluation report. The Clinical Testing reports indicate device effectiveness.

Software Verification and Validation testing was provided as part of this submission. The predicate device had the option of cephalometric exposures along with panoramic and 3D exposure; the subject device does not have the option of cephalometric exposure. For the subject device, data processing is distributed on the device and the cloud. This is not the case with the predicate; the predicate does not have any cloud-based software component. The 3D reconstruction method (CBCT mode of operation) is the same as the predicate device and is filtered back projection (FBP). The fundamental steps for the user to take an image remain the same, the difference is that the user can use their internet browser with the subject device compared to a downloadable on-premises software with the predicate. All software functions are strongly based on the predicate device.

All cybersecurity testing has been successfully performed per FDA requirements and guidance.

Page 8

The subject device software includes new features not present in the predicate device, specifically motion artifact compensation and spine artifact compensation. These were evaluated through comprehensive performance testing, including expert clinical evaluation and software verification testing. The metal artifact compensation feature remains the same as in the predicate device and has not been changed. For the motion and spine compensation features, the results of the clinical evaluation testing met prespecified success criteria via a Likert scale-based evaluation. The expert clinical evaluators reported improvements in 3D volume image quality, panoramic image homogeneity, and diagnostic interpretability when reviewing images with the compensation applied.

In summary, a comprehensive set of performance-supporting documents was included in this submission in addition to the software verification and validation reports provided. These materials include information outlined in the FDA guidance for Solid State X-ray Imaging Devices, an image quality assessment report, qualified expert evaluations conducted in accordance with the SSXI FDA guidance, a clinical image validation report, and an overview comparing the subject device's sensor performance to legally marketed predicate devices.

As mentioned above, the imaging performance of the Primevision 3D, subject device has been tested against FDA Recognized Consensus Standards. The standards used are the same with the predicate device Axeos. An additional table has been provided below for information on imaging performance results of the subject and predicate devices:
