Intended Use

The Kerator is appropriate for use with overdentures or partial dentures retained in whole or in part by endosseous implants in the mandible or maxilla.

Device Story

Kerator is a dental implant abutment providing support for prosthetic restorations (overdentures or partial dentures). It is placed into endosseous dental implants. The device is manufactured from Titanium grade Ti-6Al-4V ELI and features a TiN coating on the head. It is designed to be compatible with various third-party dental implant fixtures. The device is used by dental professionals in a clinical setting. It functions as a mechanical interface between the implant fixture and the prosthetic restoration, aiding in retention. Benefit to the patient includes improved stability and retention of dental prosthetics.

Clinical Evidence

Bench testing only. Testing included reverse engineering analysis to verify dimensional compatibility with various implant fixtures and retention testing to confirm the ability of the abutments to resist pullout from male cap/housing assemblies.

Technological Characteristics

Material: Titanium 6Al 4V ELI (ASTM F136); Male socket: DuPont Zytel 101L NC-10 Nylon and Low Density Polyethylene 993. Surface treatment: TiN coating on abutment head. Sterilization: Autoclave. Mechanical abutment for endosseous dental implants.

Indications for Use

Indicated for patients requiring overdentures or partial dentures retained by endosseous implants in the mandible or maxilla.

Regulatory Classification

Identification

- 7. Basis for Substantial Equivalence
The Kerator is substantially equivalent to previously marketed device, Locator Implant Anchor (K994257) manufactured by Zest Anchors Inc. The design features and sizing of the components were also compared and the Kerator found to be substantially the same as these systems. It is manufactured from the same FDA recognized materials and is indicated for the same intended uses as these systems. There are no significant differences between the Kerator and other systems currently being marketed which would adversely affect the use of the product. It is substantially equivalent to these other devices in design, function, material and intended use.

#### 8. Non-Clinical Testing

- The Kerator is compatible with several fixtures made by other manufactures. In order to claim the compatibility with those fixtures, the reverse engineering analysis was conducted to verify if Kertor has the same sizes and the tolerance as the predicate device which is already being marketed as the compatible ones for them. According to the test results, we conclude that they have the same size and tolerance as well as the design.
- The retention test has been carried out to confirm the ability of the abutments to resist pullout from the male cap / male housing assemblies.

## 9. Conclusion

Based on the information provided in this premarket notification, KJ Meditech Co., Ltd. concludes that Kerator is substantially equivalent to the predicate device as described herein.
