It is provided non-sterile and requires steam sterilization by the user before clinical application.

Clinical Evidence

No clinical data. Bench testing only. Fatigue testing performed per ISO 14801:2007 on worst-case scenario (smallest diameter, maximum angulation) to demonstrate mechanical integrity. Biocompatibility and sterilization validation leveraged from predicate/reference devices (K161987, K181037).

Technological Characteristics

Material: Ti-6Al-4V ELI (ASTM F136). Design: Single body or cap type; Hex or Non-Hex connection. Dimensions: 4.5mm diameter; 6.5-9.0mm heights. Sterilization: Steam sterilization (user-performed). Connectivity: Mechanical interface to dental implant fixture.

Indications for Use

Indicated for partially and fully edentulous patients requiring overdenture support in the maxillary and/or mandibular arch.

Dear Joyce Kwon:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

## Non-clinical Testing

Non-clinical testing was conducted in accordance with FDA Guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments", and it consisted of testing finished assembled implant/abutment systems of the worst-case scenario, (smallest diameter with maximum angulation) through fatigue testing. The results of the non-clinical testing demonstrate that the results have met the criteria of the standards, and the subject device is substantially equivalent to the predicate/reference devices.

## Fatigue Test

The fatigue test was performed on the subject device in accordance with ISO 14801:2007 Dentistry-Implants-Dynamic fatigue test for Endosseous Dental Implants. The worst-case scenario was chosen based on the FDA guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments".

The subject device was tested to evaluate its substantial equivalence according to the following standards. - Fatigue Test according to ISO 14801:2007

Fatigue Test according to ISO 11601:2007

## Sterilization Validation and Shelf Life Testing

User Sterilization Validation Report performed in K181037 was leveraged for the subject device. Sterilization validating testing in K181037 has been performed in accordance with ISO 17665-2 for steam sterilization. Test results have demonstrated that the SAL of 10- was achieved and all testing requirements were met. The subject devices are provided non-sterile status.

#### Biocompatibility

The Biocompatibility Test are leveraged from own reference device (K161987).

We provided the biocompatibility test report of the Ti-6Al-4V ELI (ASTM F136) in own reference device (K161987) per the FDA Guidance Document Use of International Standard ISO 10993-1, "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process". Ti-6AI-4V ELI (ASTM F136) used for the subject device and own reference device (K161987) is exactly same from same manufacturer. The reference device (K161987) support substantial equivalences because same manufacturing process and material are used for subject and own predicate device. No new issues of biocompatibility are raised for the subject devices. Therefore, no additional biocompatibility testing was required.

#### Summary of clinical testing

No clinical testing was performed for this submission.

#### Conclusions

The UF(II) Bar holder abutment constitutes a substantially equivalent medical device. This system has the same intended use and fundamental scientific technology as its predicate and reference devices. Therefore, UF(II) Bar holder abutment sand its predicates are substantially equivalent.
