Intended Use

The OT Equator is designed as an endosseous dental implant retentive component used to retain a complete or partial denture. The OT Equator is screwed into an endosseous implant in the mandible or maxilla.

The OT Equator abutments are indicated for use with the following implant systems: (list of compatible implant systems follows)

Device Description

The OT Equator Implant Anchor abutment for endosseous dental implants is appropriate for use with overdentures or partial denture retained in whole or in part by endosseous implants in the mandibula or maxilla. The device is intended for use in healthcare facilities/hospitals.

The sphere OT Equator technology represents a prosthetic abutment solution for "overdenture". The emerging profile, specifically designed to accommodate the relative interchangeable copings OT Equator, allows the coupling with a removable prosthesis or "overdenture", which is properly built only if it is properly profiled and based on the patient's gingival arch. Therefore, the removable prosthesis unloads the chewer loads on the natural gum of the intra oral arch, making the OT Equator abutments passive with lacking of solicitation.

The abutments are for straight use only and are recommended for placement on straight implant bodies with no divergence or need for angle corrections.

The OT Equator is manufactured of titanium Ti-6Al-4V (meets ASTM Standard F-136) and it is designed to retain any prosthetic restoration.

The OT Equator overdenture system is comprised of a semispherical head, a base, and a screw.

AI/ML Overview

This document is a 510(k) Premarket Notification from the U.S. Food and Drug Administration (FDA) for the OT Equator dental implant abutment. It is a regulatory document and does not contain information about the acceptance criteria or study performance of an AI/ML device.

Therefore, I cannot fulfill your request for:

  1. A table of acceptance criteria and the reported device performance
  2. Sample size used for the test set and the data provenance
  3. Number of experts used to establish the ground truth for the test set and their qualifications
  4. Adjudication method for the test set
  5. Multi-Reader Multi-Case (MRMC) comparative effectiveness study effect size
  6. Standalone performance
  7. Type of ground truth used
  8. Sample size for the training set
  9. How the ground truth for the training set was established

The document focuses on demonstrating substantial equivalence of the OT Equator device to previously cleared predicate devices based on materials, design, intended use, and manufacturing processes, rather than presenting a study related to an AI/ML device and its performance metrics. The non-clinical tests mentioned (biocompatibility, sterilization validation, reverse engineering analysis) are performed on the physical dental implant abutment and its interaction with implant systems, not on an AI system.

DISCUSSION OF NON CLINICAL TESTS

Biocompatibility

The submitted device, as the predicate devices already licensed (OT EQUATOR K142211 and K160382), is classified as permanent duration (> 30 days), mucosal membranes contacting device. The materials used to manufacture the submitted device are identical to the materials used for the identified predicate devices, the already licensed OT EQUATOR (K142211 and K160382). The materials used to manufacture the submitted device are identical to the materials used for the identified predicate devices and the same process is performed, including the TiN (Titanium Nitride) coating for the OT EQUATOR abutment; the modified surface of the abutment after the coating process is identical to the surface of the predicate devices. The type and duration of patient contact are the same as well.

Therefore, the results of the biocompatibility tests performed on the predicate devices OT EQUATOR apply also to the subject device and there was no need to perform new biocompatibility testing on the subject device OT EQUATOR. No additional biocompatibility testing is needed for the determination of substantial equivalence.

Sterilization Validation

Steam sterilization validation test, conducted on the predicate device OT EQUATOR (K142211) according to ISO 17664 and ISO 11737-1/-2 in order to demonstrate as SAL of 10-6 related to the OT Equator abutments, are considered still valid, since the materials and packing of the subject device are the same of the predicate.

Reverse engineering analysis

In order to ensure that the OT Equator abutment can be coupled with the related compatible implant a reverse engineering analysis was conducted on the submitted device, as for the predicate devices already licensed; 10 samples of OEM implant system were used in the reverse engineering analysis: 10 OEM implant bodies and 10 OEM screws were reversed as for the predicate and reference devices, and the results were reported in a chart form.

The implant dimensions were detected with a stereo microscope and with a wide range of calibrated plugs. The dimensions of the threaded holes and the related tolerance degree were detected with the "qo/no qo" threaded gauges. In the same way the maximum depth of the threaded hole was detected with the related threaded gauge, with the aid of the profile projector.

{11}------------------------------------------------

The results of nonclinical tests demonstrate that the device is equivalent to the predicate devices.

SUBSTANTIAL EQUIVALENCE

The OT EQUATOR is same or similar in materials, design and intended use to the predicate devices. In further support of a substantial equivalence determination, hereunder is a comparison chart with the submitted device and the predicate devices.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE DISCUSSION:

The Indications for Use Statements shown above in the comparison chart a list of compatible implant bodies. The differences between the Indications for Use of the subject device and the primary predicate device is the addition of compatible implant bodies (Tri Dental Implants Int. AG, Altatec GMBH, Dentis Co., Dentsply Implants Manufacturing GMBH and Megagen Implant Co.).

As shown in the table above, the submitted device is substantial equivalent in all features: indications for use and intended users, materials, manufacturing process, cuff width, height, status, components.

The subject device varies from the predicate devices only for the list of compatible implant systems, thus the only difference is in the interface connections between the abutments and the compatible implant bodies, that have specific dimensions according to the compatible implant systems. As for the predicate devices, in order to ensure that the OT Equator abutment can be coupled with the related compatible implant a reverse engineering analysis was conducted on the submitted device.

There are no additional differences, thus it was concluded that the subject dental implant is substantially equivalent to the predicate devices.

CONCLUSIONS

Based on the available information, we conclude that the OT Equator is substantially equivalent to the existing legally marketed device under Federal Food, Drug and Cosmetic Act. Therefore, the subject device is determined to be equivalent to the predicate devices.
