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 (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. 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.

{1}------------------------------------------------

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 803) for devices or postmarketing safety reporting (21 CFR 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 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 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.

#### Non-Clinical Test Data

No need to perform any new additional non-clinical testing for the subject device since the subject device compared to predicate device are substantially equivalent in indications, fundamental technology, material and design. The predicate device may be leveraged for the subject devices because of using the same materials, manufacturing methods, and sterilization procedures. Although the dimensions are slightly different, it doesn't impact product's safety and effectiveness because the predicate device is the worst case based on the product's dimensional comparison analysis provided.

Below tests were performed for primary predicate and leveraged for the subject device:

- . Sterilization validation according to ISO 17665-1. ISO 17665-2, and ISO 14937 referenced in K193425.
- Biocompatibility according to ISO 10993-5 and ANSI/AAMI ST72 referenced with K193425. .

Non-clinical performance data submitted to demonstrate substantial equivalence included:

- . Static and fatigue testing according to ISO 14801. No clinical data is included in this submission.
The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the primary predicate.

#### Equivalence to Marketed devices

Mechanical performance testing was performed according to ISO 14801. For each compatible implant line, worst-case constructs were subjected to static compression and compression fatigue testing. Minor differences in the designs, dimensions, sizes, or compatible implant lines among the subject device, the primary predicate device, and the reference devices do not affect substantial equivalence. These minor differences do not impact substantial equivalence

To the right of the triangles, the words "ARUM" and "DENTISTRY" are written in a bold, dark brown font, with "DENTISTRY" appearing below "ARUM".

because these differences are related to the compatible implant designs, or are mitigated by the mechanical performance testing.

### Conclusion

The Customized Abutment constitutes a substantially equivalent medical device, meeting all the declared requirements of its intended use. This system has the same intended use and fundamental scientific technology as its predicate devices. Therefore, the Customized Abutment and its predicates are substantially equivalent.
