Intended Use

Rotograph Prime and I-MAX are extra-oral dental panoramic X-ray units to radiograph teeth, jaw and oral structures.

The devices are operated and used by dentists, radiologists and other legally qualified health care professionals.

They can be used with both pediatric and adult patients.

Device Description

Rotograph Prime (and I-MAX under trade mark Owandy Radiology) is a complete panoramic X-ray system. The basic version performs:

  • -Panoramic adult or child exams, with 3 sizes and 3 tvpes of biting for a total of 18 combinations with automatic parameter selection; with manual selection, it is possible to select a high voltage between 60kV and 70kV, in 2kV steps and anodic current from 2 mA to 7.1 mA in the R20 scale steps.
  • -Sinus mode to take exams of the paranasal sinuses with front projection (postero/anterior);
  • -TMJ (closed/open mouth) exams in lateral projection.

XP (Extended Projection Package) optional function allows to carry out the following additional exams:

  • -Right or left half-panoramic, to be used when the patient is known to have a problem only on one side of the arch, in order to reduce radiation;
  • -Low dose Panoramic, which reduces the dose radiated by excluding the TMJ's ascending rami from the radiograph;
  • Frontal dentition, for a radiograph of the front part (roughly from canine to canine); -
  • -Ortho Rad Panoramic which reduces teeth overlap, thereby improving the diagnosis of interproximal decay:
  • Bitewing left or right for lateral dentition (generally from eighth to fourth) with a trajectory that reduces teeth overlap;
  • -Bilateral Bitewing (left and right), which sequentially performs both bitewings, showing them on the same image.

The images are acquired by a CCD sensor and are displayed on a monitor, and image manipulation, archiving and communication are performed via a computer (not included in the device). In particular, Rotograph Prime is equipped with a PAN sensor: it is suitable for Panoramic-type imaging, all Panoramic, i.e. all images with about 14cm-high field; all Panoramic. TMJ, and Sinus images belong to this type.

AI/ML Overview

This document describes the Rotograph Prime and I-MAX extra-oral dental panoramic X-ray units and compares them to a predicate device, the Rotograph EVO D, to demonstrate substantial equivalence for FDA 510(k) clearance.

Here's the breakdown of the acceptance criteria and study information:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state formal "acceptance criteria" in a quantitative sense for image quality or clinical performance metrics. Instead, it relies on the comparison to a predicate device (Rotograph EVO D) and conformance with recognized international standards for safety and performance. The primary acceptance criterion for the premarket notification appears to be demonstrating substantial equivalence to the predicate device, meaning the new device is as safe and effective.

The provided tables mainly focus on comparing technical specifications and features. The key "performance" aspect is image quality, which is addressed through a comparative study.

Acceptance Criterion (Implicit)Reported Device Performance (as per document)
Image Quality Equivalence to Predicate Device"The equivalence of the image quality of panoramic radiographies of the subject device has been assessed with image comparison tests." (Specific metrics or results not detailed in this summary, but a separate annex titled "7_Image_Quality_Comparison" is mentioned as having been supplied)
Conformance with International Standards for Safety and Essential Performance (examples of key standards)Conforms to: - IEC 60601-1: General requirements for basic safety and essential performance - IEC 60601-1-2: Electromagnetic compatibility - IEC 60601-1-3: Radiation Protection in Diagnostic X-Ray Equipment - IEC 60601-2-63: Particular requirements for dental extra-oral X-ray equipment - IEC 62304: Medical device software - ANSI/AAMI ES60601-1: General Requirements - CAN/CSA-C22.2 No. 60601-1: General requirements for basic safety and essential performance - IEC 60601-1-6: Usability - IEC 62366: Usability engineering - ISO 10993: Biological evaluation of medical devices (Parts 2, 5, 10, 12)
Software Validation (Moderate Level of Concern)"The software validation activities were performed in accordance with the FDA Guidance, 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices' (May 11, 2005)." Device software is classified as "Moderate Level of Concern."
Device not introducing new questions of safety or effectiveness (based on technological differences)"The review of the technological differences...shows that they are due only to technological evolution and removal of not needed functions and/or version so they do not raise any new questions regarding safety or effectiveness..."
Biocompatibility of patient-contacting components"All parts in contact with patient have been assessed according to ISO 10993."
Electrical safety, EMC/EMI, and Performance Testing (general categories)"Electrical safety, EMC/EMI testing, biocompatibility consideration, performance and image quality testing, verification and validation testing were performed to support the substantial equivalence determination." (Specific results not detailed in this summary but mentioned as provided in test reports).
Total Filtration compliance"Due to the reduced kV range, the total filtration has been reduced maintaining the compliance with 21CFR 1020.30."

2. Sample Size Used for the Test Set and Data Provenance

  • Test Set Sample Size: The document mentions "image comparison tests" and refers to "annex 7_Image_Quality_Comparison" for details. However, it does not explicitly state the number of images or cases used in these image comparison tests within the provided text.
  • Data Provenance: Not explicitly stated. Given the manufacturer is based in Italy (Villa Sistemi Medicali S.p.A.), and the predicate device is also from the same manufacturer, it's highly probable the data was generated in Europe, possibly Italy. The document indicates it's a premarket submission for a new device, implying it would involve newly acquired images for testing, making it somewhat "prospective" in the context of comparing a new device against an existing one, although the images themselves might be taken from a test phantom or patient data collected specifically for the comparison. It is not explicitly stated whether it uses patient data or phantom data.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts

This information is not provided in the document. The document refers to "image comparison tests" but does not detail how ground truth was established, who participated, or their qualifications.

4. Adjudication Method for the Test Set

This information is not provided in the document.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

  • MRMC Study: No, this document describes an X-ray imaging device, not an AI software. Therefore, an MRMC comparative effectiveness study comparing human readers with and without AI assistance is not applicable and was not performed.
  • Effect Size: Not applicable.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

No, this document describes an X-ray imaging device, which is a physical hardware product. Therefore, a standalone algorithm-only performance study is not applicable. The image quality comparison is likely testing the device's ability to produce diagnostically equivalent images to the predicate, irrespective of an AI algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The document mentions "image comparison tests" to assess "equivalence of the image quality." It does not specify the type of ground truth used for these images. It's common in such comparisons for technical performance (e.g., resolution, contrast, artifact levels) to be assessed against expected values or by visual comparison by experts. It is possible a gold standard phantom or reference images were used, but this is not explicitly stated.

8. The Sample Size for the Training Set

This information is not applicable as the device is an X-ray hardware system, not an AI model that requires a training set.

9. How the Ground Truth for the Training Set was Established

This information is not applicable for the same reason as point 8.

The device is operated and used by dentists, radiologists and other legally qualified health care professionals. It can be used with both pediatric and adult patients.

Rationale for Substantial Equivalence

Here below a summing up the main features of the proposed and predicate devices in order to point out the significant similarities and differences.

Rotograph Prime (and I-MAX under trade mark Owandy Radiology) is based on a well-known technology and it has the same indication for use as the predicate device as reported here below.

Villa Sistemi Medicali - Rotograph PrimeandOwandy Radiology - I-MAX510(k) number tbdVilla Sistemi MedicaliRotograph EVO D510(k) number K090749
Intended UseRotograph Prime is an extra-oral dental panoramicX-ray unit to radiograph teeth, jaw and oralstructures.The device is operated and used by dentists,radiologists and other legally qualified health careprofessionals.It can be used with both pediatric and adultpatients.Extraoral source x-ray system, which areintended for dental radiographic examination ofthe teeth, jaw, and oral structures, specificallyfor panoramic examinations and implantologyand for TMJ studies and cephalometry

Rotograph Prime (and I-MAX under trade mark Owandy Radiology) has the same functions in the same environment as the predicate device. In particular, the proposed devices perform the same exams for the examination of teeth, jaw and oral structures, as the Rotograph EVO D device.

The proposed devices also use a high frequency x-ray generator with the same x-ray exposure time control and focal spot value of the predicate device.

In the subject devices, patient positioning is assured through two laser pointers that allow to locate the reference planes, as in Rotograph EVO D predicate device.

Image /page/6/Picture/0 description: The image features a logo with a stylized white letter 'N' set against a blue square background. Below the square, the word 'VILLA' is written in white, bold letters. The logo appears clean and modern, with a simple color scheme.

The subject device detector is exactly the same model as the detector. The equivalence of the image quality of panoramic radiographies of the subject device has been assessed with image comparison tests.

For all these reasons, Rotograph Prime (and I-MAX under trade mark Owandy Radiology) share the fundamental technological characteristics as the predicate device, even if there are some minor differences, not affecting the safety and effectiveness, between the subject and predicate devices.

The following tables list the similarities and the differences between the subject device (Rotograph Prime under trade mark Villa Sistemi Medicali and I-MAX under trade mark Owandy Radiology) and the predicate device (Rotograph EVO D, manufactured by Villa Sistemi Medicali and cleared by FDA with 510(k) number K090749).

Image /page/9/Picture/0 description: The image is a logo for Villa. The logo features a white stylized letter "V" inside of a blue square. Below the square is the word "VILLA" in white, block letters.

Detailed description of the differences

As detailed described on the following paragraphs, all the differences do not affect the safety and effectiveness of the subject devices.

Versions .

The Predicate device is available also in analog version (using film-screen combination as image receptor). The subject device is available only in digital version (using the same digital detector as the predicate device). This choice has been driven by the current market and technology trend. Analog extraoral dental units have substantially disappeared from the market in the last 5 years.

. Exam projections

Ceph

The predicate device includes, as an option, also cephalometric examination of the skull. The subject device doesn't include cephalometric exams. The reason is that the device is dedicated to a market segment in which doctors don't need this exam. The fact that this function is not offered has no impact on the performance of the other available projections neither introduces differences vs pan-only version of the predicate device. The subject device is therefore equivalent to the pan-only version of the predicate device.

Adult Pan Scan time

During panoramic exams, the machine has to perform movements according to the selected exam specific trajectory; the exam scan time is the time taken by the machine to complete these movements. The panoramic exam trajectory implemented in the subject device is slightly slower from the one on the predicate device in order to adapt to the small geometric differences between the units; for this reason the scan time is increased of about 4%.

Cihild Pan Scan time

Due the fact that on the subject device the scan time has been slightly increased, it has been implemented a PAN exam specific for children with a reduced scan time.

In fact, the trajectory of child panoramic exam movements is shorter and dedicated to child patients giving a dose reduction vs. the adult exam. This trajectory has been already used on previous Villa panoramic units. It doesn't require different instructions of patient positioning respect to the adult exam.

Generator / tube ●

kV Range and mA range

The radiological parameters ranges have been optimized for the exam projections (on subject device ceph exams that requires higher dose is not present) and receptor type (on subject device film version that requires higher dose is not present) available on the subject device.

Total filtration

Due to the reduced kV range, the total filtration has been reduced maintaining the compliance with 21CFR 1020.30

Collimator

Due to the absence of the ceph exams, only one collimator slot is needed on the subject device. This collimator slot corresponds to the predicate devices for the exam projections available on the subject device.

{10}------------------------------------------------

Image /page/10/Picture/0 description: The image is a logo for Villa. The logo features a white stylized letter "V" inside of a blue square. Below the square is the word "VILLA" in white, block letters.

Patient positioning ●

Height of chin support

The Height range of chin support has been reduced based on the following assumption: 975mm correspond to the height of the chin of a 7 years old child, according to the Dreyfuss Tables and 1635mm correspond to the height of the chin of a man of about 190cm of height. According to the Dreyfuss tables this cover about 99% of the adult population.

Patient Positioning orientation

A difference has been introduced in the patient orientation with respect to the machine and operator. In the predicate device, the patient is facing the column; in order for the operator to have visibility of the patient's face, a mirror is present on the column. In the subject device the patient is facing to the equipment, making it possible for the operator to have a direct face visibility of the patient, therefore improving the positioning accuracy and patient's confidence.

. User interface

The user interface of the subject device is made by a keyboard on the machine to drive movements and lasers plus a virtual control panel on PC to select exams and their parameters. The user interface of the predicate device is on board but its digital version has also a virtual control panel on the PC with which exams and their parameters can be selected. The reason of this difference is related to the fact that the subject device, being only digital, always requires a PC so the on board keyboard could be removed while the predicate device needed the on-board keyboard for exam selection for the analog version that doesn't require a PC to work.

Installation .

Type of installation

The weight reduction of the subject device respect to the predicate device made it possible to produce a fully wall-mounted version which leaves the floor space free from support structures and more comfortable for the patient, especially in case of particular needs, such as wheelchairs.

Current rating

Due to the different radiological parameters ranges respect to the current rating of the subject device is also reduced

Weight (wall mount version)

Due to the absence of analoq version and cephalometric device, and thanks to the use of light-weight materials and optimized components design, the weight of subject device has been significantly reduced compared to the predicate device. The weight reduction doesn't affect the robustness of the device

Dimensions (wall mount version)

Due to the optimized components design, the dimension of subject device has been reduced compared to the predicate device

Regarding software ●

The elimination of the analog (film) version, the cephalometric option and the automatic contributed to the simplification both of the overall electronic and of the software architecture. The changes to the virtual control panel on PC - to select exams and their parameters - are limited just only to the cosmetic graphics elements. No other significant change is present in the software.

Image /page/11/Picture/0 description: The image is a logo for Villa. The logo features a stylized white letter "N" on a blue square background. Below the square is the word "VILLA" in a sans-serif font, also in white.

The review of the technological differences between the subject device and the predicate device shows that they are due only to technological evolution and removal of not needed functions and/or version so they do not raise any new questions regarding safety or effectiveness of the Rotograph Prime (and I-MAX under trade mark Owandy Radiology). Basing on the above considerations, we can conclude that the Rotograph Prime (and I-MAX under trade mark Owandy Radiology) is as safe and effective as the predicate device.

PERFORMANCE DATA AND TESTING EVIDENCE:

Electrical safety, EMC/EMI testing, biocompatibility consideration, performance and image quality testing, verification and validation testing were performed to support the substantial equivalence determination.

A risk analysis was performed to analyze the hazards associated with the changes.

Non-clinical considerations according to FDA Guidance "Guidance for the submissions of 510(k)'s for Solid State Xray Imaging Devices" were performed in order to assess the image quality and the relevant analysis has been supplied (see annex 7_Image_Quality_Comparison).

The intended use of the proposed device is the same of the predicate device. Concerning Conclusion: the technical characteristics, it has been demonstrated that Rotograph Prime (and I-MAX under trade mark Owandy Radiology) does not introduce innovative aspects and does not arise different considerations regarding the safety and the relevant risks linked to the device. Despite some minor technological differences, Rotograph Prime (and I-MAX under trade mark Owandy Radiology) can be considered as safe and as effective as the predicate device and therefore substantially equivalent to the predicate Rotograph EVO D.
