No
The device description clearly states it is a physical prosthetic abutment made of titanium, comprised of a head, base, and screw. It is a hardware component for dental implants.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The device is described as a "dental implant retentive component used to retain a complete or partial denture." This is a mechanical function within the body.
- Device Description: The description focuses on the physical components (semispherical head, base, screw), material (titanium), and how it functions to retain a denture.
- Lack of IVD characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.
IVD devices are used in vitro (outside the body) to analyze biological samples. This device is used in vivo (within the body) as a structural component for dental prosthetics.

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.
OT Equator technology represents a prosthetic abutment solution for "overdenture". The sphere 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 prosthetic restoration.
The OT Equator overdenture system is comprised of a semispherical head, a base, and a screw.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Biocompatibility: The materials are identical to the predicate, the Sphero-Block (K033630). All materials, including the coating for the OT EQUATOR Abutment, TiN (Nitride), are identical to the Sphero-Block and components cleared in the predicate 510(k). Therefore, no biocompatibility testing was conducted for the subject OT EQUATOR based on the materials being identical to the predicate, conformance to an FDA recognized standard (i.e. ASTM F136), and all components being manufactured using the same process. No additional biocompatibility testing is needed for the determination of substantial equivalence.
Mechanical strength: Compression tests (static and dynamic) were run to check the various connections for adequate strength, according to FDA Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments, 2004 and ISO 14801 standard, Dentistry- implants- dynamic Fatigue Test For Endosseous Dental Implants. The test results demonstrate that the products demonstrate substantial equivalence performance to the declared predicate devices.
Fatigue: Fatigue tests were performed according to ISO 14801 on the OT Equator models. The smallest compatible implant was chosen as worst case. Test results provide evidence that OT Equator demonstrates substantial equivalence performance as compared to the declared predicate devices.
Sterilization Validation: Steam sterilization validation test was conducted according to ISO 17664 and ISO 11737-1/-2 in order to demonstrate as SAL of 10-6 related to the OT Equator abutments.
Reverse engineering analysis: A reverse engineering analysis was conducted to ensure perfect coupling with compatible implants. The implant dimensions were detected with a stereo microscope and calibrated plugs. The exact dimensions of the threaded holes and tolerance were detected with "go/no go" threaded gauges. The maximum depth of the threaded hole was detected with a threaded gauge and a profile projector. Tests were conducted on a statistically significant number of OEM implant systems. The analysis demonstrated the compatibility of the subject abutment to the identified dental implant body.

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.
OT Equator technology represents a prosthetic abutment solution for "overdenture". The sphere 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 prosthetic restoration.
The OT Equator overdenture system is comprised of a semispherical head, a base, and a screw.
5
The proposed device and the predicates SPHERO FLEX and SPHERO BLOCK (K950260 -K950261 - K033630) are equivalent in some specifications (the dimensions of the head between the predicate Sphero-Block and OT Equator differ slightly), and identical in other specifications as the interface connections between the abutments and the implant body, the materials, the manufacturing process, the technological characteristics and the Indications for Use.
The Titanium abutment has one side with a thread to secure the connection to a dental implant. On the other side there is a hemisphere that must be connected to the prosthesis.
The OT Equator varies from the predicate Sphero Block as follows: on the Sphero block the complete round sphere inclusive of the hexagon base is 3.4mm in height; the OT Equator does not contain a complete round sphere or a hexagon base, and it is 2mm in height. The diameter of the Sphero Block sphere and the OT Equator half-sphere is the same of 2.5 mm, they vary only in height.
The anchoring of the prosthesis to the attachments is ensured by the coupling precision between the retentive cap inserted in a steel housing and the spherical section of the upper part of the abutments. In order to enable this connection the following components have been made:
The METAL HOUSING is a stainless steel prefabricated device with proper internal dimensions able to host the OT EQUATOR retentive cap in order to secure a coupling between abutment/retentive cap as precise as possible.
The metal housing must be placed into the prosthesis, then a RETENTIVE CAP must be inserted into the metal housing, then the prosthesis must press on the abutments for the connection of the denture.
Retention caps are elastic elements that allow the union between the steel housing and the abutment by regulating the retention strength in a prosthetic project. The special internal design of the cap allows embracing the attachment's ball when it is snapped into the cap .
The retention caps are manufactured in different materials that give to the product different retention strength. They are also made in different color in order to permit to selection of the elastic properties of the material of which they are composed. The different colors allow distinguishing the different retention strength.
The subject device is provided with a threaded stem to be screwed into a dental implant. This component is coated with TiN in the upper part, where it must be connected with Retentive caps.
The OT Equator and the predicate Sphero-Block are identical in every way (materials, additives, manufacturing process and intended use) except the dimensions, in that the dimension of the head of the OT Equator is not a complete sphere but semi-sphere. The Indications for Use Statement for the subject abutment has been modified to add new compatible implant fixtures has compared to the predicate; however the new compatibility does not change the intended use as compared to the declared predicate.
The other components listed below are also different only in size (they must fit with the semisphere and a complete sphere). The tools are the same as used with the Sphero-Block.

DISCUSSION OF NON CLINICAL TESTS
Biocompatibility
The materials are identical to the predicate, the Sphero-Block (K033630). All materials, including the coating for the OT EQUATOR Abutment, TiN (Nitride), are identical to the Sphero-Block and
9
components cleared in the predicate 510(k). Therefore, no biocompatibility testing was conducted for the subject OT EQUATOR based on the materials being identical to the predicate, conformance to an FDA recognized standard (i.e. ASTM F136), and all components being manufactured using the same process. No additional biocompatibility testing is needed for the determination of substantial equivalence.
Mechanical strength
In order to verify whether the final strength of the product meets the design requirements the mechanical strength was analyzed according both to FDA Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments, 2004 and ISO 14801 standard, Dentistry- implants- dynamic Fatigue Test For Endosseous Dental Implants.
Compression tests (static and dynamic) were run to check the various connections for adequate strength. The test results demonstrate that the products demonstrate substantial equivalence performance to the declared predicate devices.
Fatique
Fatigue tests were performed according to ISO 14801 on the OT Equator models. Also for this test the smallest compatible implant was chosen as worst case. Test results provide evidence that OT Equator demonstrates substantial equivalence performance as compared to the declared predicate devices.
Sterilization Validation
Steam sterilization validation test was conducted according to ISO 17664 and ISO 11737-1/-2 in order to demonstrate as SAL of 10-6 related to the OT Equator abutments.
Reverse engineering analysis
In order to ensure that the OT Equator abutment can be perfectly coupled with the related compatible implant a reverse engineering analysis was conducted,
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.
Information provided, in the reverse engineering analysis report included identification of features critical to fit, dimensions, tolerances, and cross-sections CAD images showing the assembled devices, dimensions, and interface gaps. The analysis demonstrated the compatibility of the subject abutment to the identified dental implant body.
The results of nonclinical tests demonstrate that the device is equivalent 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.
