Dear Boyeon Lim:

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 (the 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 available 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

### MR Environment Condition

Non-clinical worst-case MRI Review was performed to evaluated the metallic. The Customized Abutment in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry 0., 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 bodied, dental abutments and, fixation screws) and material composition. 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.

#### Biocompatibility

Biocompatibility of Ti-6Al-4V Eli (ASTM F136) demonstrated by the reference ARUM DENTISTRY submission, K223634, using the same materials and manufacturing processes as the subject device.

#### Sterilization validation

The Customized Abutment delivered non-sterile to be end-user sterilized, the recommended sterilization has been validated according to ISO 17655-1 and to applicable recommendations in the FDA quidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, issued on March 17, 2015". The predicate devices may be leveraged for the subject devices because of using the same materials, manufacturing methods, and sterilization procedures. The sterilization methods were leveraged from predicated K223634. The worst-case construct was tested, and results demonstrated equivalence to the predicate devices.

#### Non-Clinical Test Data

Non-clinical performance data submitted to demonstrate substantial equivalence included: Biocompatibility testing of the K223634 predicate device to ISO 10993-5 and ANSI/AAMI ST72 in support of the Subject device; reverse engineering of the OEM implant bodies, OEM abutments and OEM abutment screws to confirm compatibility; and static and fatigue testing according to ISO 14801. No clinical data is included in this submission.

# Conclusion

Slight differences in the compatible implant system abutments available in the Subject and Predicate device systems does not change the intended use of the devices to provide support for single or multi-unit prosthetic restorations.

{11}------------------------------------------------

K234112

The slight differences in the Technological Characteristics of the Subject and Predicate devices do not change the intended use of the devices to provide support for single or multiunit prosthetic restorations or introduce new risk or concerns of safety and effectiveness. Differences in Subject device abutment design parameters were validated with respect to intended use through Performance testing.

Overall, the Customized Abutment is substantially equivalent to the Predicate device.
