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 OT Equator is manufactured of titanium Ti-6AI-4V (meets ASTM Standard F-136) and it is designed to retain any compatible prosthetic restoration.
The OT Equator overdenture system is comprised of a semispherical head, a base, and a screw.
This document is a 510(k) premarket notification for the "OT EQUATOR" device, an endosseous dental implant abutment. The primary purpose of this submission is to demonstrate substantial equivalence to a legally marketed predicate device, rather than to establish new performance metrics through clinical trials. As such, the information typically found in acceptance criteria and detailed study results for novel devices is not explicitly provided in the same format.
However, based on the provided text, we can infer how the device meets acceptance criteria through its demonstrated substantial equivalence to the predicate.
Here's an analysis of the requested information based on the provided text:
1. A table of acceptance criteria and the reported device performance
Since this is a substantial equivalence submission, the "acceptance criteria" are implied by the characteristics of the legally marketed predicate device (OT EQUATOR, K142211). The "reported device performance" for the new submission (OT EQUATOR, K160382) is its equivalence to these characteristics.
| Feature/Acceptance Criterion (Implied by Predicate) | Reported Device Performance (Submitted OT EQUATOR K160382) |
|---|---|
| Indications for 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." (Same as predicate) |
| Intended Users | Adequately trained dental technicians and dentists. (Same as predicate) |
| Material (Abutment) | Titanium 6Al-4V (Same as predicate) |
| Material (Male socket) | Rilsan, Pebax, Kepital (Same as predicate) |
| Material (Housing) | Stainless Steel AISI303 (Same as predicate) |
| Platform Diameter | According to the compatible implant (see table above, indication for use) (Same as predicate) |
| Surface treatment | TiN coating only for the head part of the abutment (Same as predicate) |
| Cuff Width | 1mm - 2mm - 3mm - 4mm - 5mm - 6mm- 7mm (Same as predicate) |
| Height | 2 mm (Same as predicate) |
| Components | OT EQUATOR PROFILE kit contains: Ot Equator Profile abutment, metal housing, retentive caps, protective disk. (Same as predicate) |
| Sterilization | Marketed non sterile, to be sterilized before insertion in patient's mouth. (Same as predicate) |
| Reusable | No (Same as predicate) |
| Biocompatibility | Meets standards for permanent duration (> 30 days), mucosal membranes contacting device (demonstrated by predicate). |
| Sterilization Validation | Achieves SAL of 10-6 (demonstrated by predicate). |
| Coupling with compatible implant | Successful coupling as validated by reverse engineering analysis (results reported in a chart form, not detailed in text). |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document primarily relies on non-clinical tests to demonstrate substantial equivalence. For the reverse engineering analysis:
- Sample Size: "a statistically significant number of OEM implant systems" were used. The exact number is not specified.
- Data Provenance: Not explicitly stated, but the company (Rhein'83 SRL) is based in Italy. The testing would have been performed on commercially available implant systems. It is not a clinical study, so terms like retrospective/prospective don't directly apply.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable. This submission concerns a physical device and its material/design characteristics validated against a predicate device and engineering standards, not diagnostic performance requiring expert interpretation of medical images or conditions. The "ground truth" for the non-clinical tests (like reverse engineering) would be the technical specifications of the implants and the device, measured by calibrated instruments, not expert consensus.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. Adjudication methods are typically used in clinical studies with subjective interpretations. The non-clinical tests described (biocompatibility, sterilization validation, reverse engineering) rely on objective measurements and established standards.
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
Not applicable. This device is a dental implant abutment, not an AI-powered diagnostic tool, and no MRMC study was performed or is relevant.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This device is a physical medical device, not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
For the non-clinical tests:
- Biocompatibility: Ground truth is established by international standards (e.g., ISO 10993 series, though not explicitly detailed here, it's implied by the reference to "permanent duration (> 30 days), mucosal membranes contacting device").
- Sterilization Validation: Ground truth is established by international standards (e.g., ISO 17664 and ISO 11737-1/-2) for a Sterility Assurance Level (SAL) of 10-6.
- Reverse Engineering Analysis: Ground truth is the precise dimensions and specifications of the compatible OEM implant systems. These are objective engineering measurements.
8. The sample size for the training set
Not applicable. This is not a machine learning or AI device, so there is no "training set."
9. How the ground truth for the training set was established
Not applicable. No training set exists.

DISCUSSION OF NON CLINICAL TESTS
Biocompatibility
The submitted device, as the predicate device, is classified as permanent duration (> 30 days), mucosal membranes contacting device.
The materials of the submitted device are identical to the ones of the predicate, the already licensed OT EQUATOR (K142211). All materials, including the coating for the OT EQUATOR Abutment, TiN (Nitride), are identical to the materials used to manufacture the predicate OT EQUATOR and its components (all cleared with 510(K) n. K142211). All the components are manufactured using the same process. Therefore the results of the biocompatibility tests performed on the predicate device OT Equator apply also to the subject device and there was no need to perform new biocompatibility testing on the subject device OT EQUATOR.
Sterilization Validation
Steam sterilization validation test, conducted on the predicate device OT Equator 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.
{8}------------------------------------------------
Reverseengineeringanalysis
In order to ensure that the OT Equator abutment can be perfectly coupled with the related compatible implant a reverse engineering analysis was conducted, as for the predicate already licensed. The implant dimension were detected with a stereo microscope and with a wide range of calibrated plugs. The exact dimensions of the threaded holes and the related tolerance degree were detected with the "go/no go" 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. The tests were conducted on a statistically significant number of OEM implant systems, and the
results were reported in a chart form.
The results of nonclinical tests demonstrate that the device is substantalyequivalent to the predicate device.
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 WITH THE PREDICATE DEVICE
The proposed device and the predicate OT EQUATOR already licensed (K142211) are identical in all specifications as the materials, the manufacturing process, the technological characteristics and the indications for use except for the interface connections between the abutments and the compatible implant bodies,that have specific dimensions, according to the compatible implant systems.
The subject device varies from the predicate already licensed only for the list of compatible implant systems.
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 substantially equivalent to the predicate device.
