#### 4. Device description

The IU Implant System Abutment is a dental implant superstructure made of titanium alloy. It is an abutment used to support or maintain the restoration after the implantation of the fixture in the oral cavity.

The abutments are provided non-sterile and should be sterilized before use.

#### 5. Indication for use

The Warantec dental abutment is intended to be used with the root-form endosseous dental implant to aid in prosthetic rehabilitation.

#### 6. Substantial equivalence comparison

The IU Implant System is similar designs and dimensions, and has the same material, intended use, surface treatment and technological characteristics as the identified primary predicate device (K172345) and reference devices (K081748 / K160828). When compared with predicate device, no new questions of substantial equivalence have been raised for the IU Implant System Abutment.

| Device Name | Indication for use |

| IU Implant System<br>Abutment<br>(Subject device) | The Warantec dental abutment is intended to be used with the root-form<br>endosseous dental implant to aid in prosthetic rehabilitation. |
| IU Implant System<br>(Primary Predicate<br>Device: K172345) | The IU Implant System is intended to be surgically placed in the bone of the<br>upper or lower jaw arches to provide support for prosthetic devices, such as<br>artificial teeth, and to restore the patient's chewing function. |
| ONEPLANT Dental<br>Implant System<br>(References Predicate<br>Device: K081748) | ONEPLANT is designed for use in dental implant Surgery. These are intended<br>for use in partially or fully edentulous mandibles and maxillae to support for<br>single or multiple-unit restorations such as cemented retained, screw retained, or<br>over denture restorations and terminal or intermediate abutment support for fixed<br>bridework. |
| Implantium® /<br>SuperLine®<br>Prosthetics<br>(References Predicate<br>Device: K160828) | Implantium® SuperLine® Prosthetics is intended for use as an aid in prosthetic<br>rehabilitation |

{5}------------------------------------------------

The subject device (IU system abutment) has substantially the equivalent in indications and design principles as the predicate and reference devices listed above.

All are intended for use with endosseous dental implants in the maxilla and mandible to provide functional and prosthetic rehabilitation of the edentulous maxilla and mandible.

The differences between the target device IFUS(Indications for Use Statements) and the predicate and reference device are related to the specific device names, design feature, compatible implant lines.

None of these differences impact substantial equivalence. because all IFUS express equivalent intended use to facilitate dental prosthetic restorations, and the indications are expressed equivalently using different specific wording.

#### 7. Non-clinical testing data

Non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence included:

• Steam sterilization validation according to ISO 17665-1 and ISO 17665-2, demonstrating a sterility assurance level (SAL) of 10-6.

• Biocompatibility of Ti-6A1-4V ELI (ASTM F136) demonstrated by the referenced Warantec submission. K172345, using the same materials and manufacturing processes as the subject device.

• Fatigue testing was conducted on the worst case according to ISO 14801:2016 and the FDA Special Controls Guidance Document for Root-form Endosseous Dental Implants and Endosseous Dental Abutment.

· Non-clinical worst-case MRI review was performed to evaluate the metallic IU System Abutment devices in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry O., Jana G. Delfino, and Sunder Rajan. "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795), based on the entire system including all variations (all compatible implant bodies, dental abutments, and fixation screws) and material compositions. The rationale addressed parameters per the FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment', including magnetically induced displacement force and torque.

No clinical data were included in this submission.

#### 8. Conclusion

The subject device has the similar technological characteristics to the predicate device, main material, indication for use and design.

Based on the information provided for this premarket notification of Warantec Co., Ltd. conclude that IU System Abutment are substantially equivalent to predicate devices.
