### Dear Won-Yi Choi:

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.

K190112). Digitally designed CAD/CAM abutments must have a 0.5 mm minimum gingival height dimension.

The Titanium Base abutment is composed of two-piece abutment that is a titanium base at the bottom and a zirconia superstructure (CAD/CAM patient specific superstructure) at the top. The zirconia superstructure is straight only and is not to be designed to provide an angle or divergence correction.

For the Ti-Base the design parameters for the CAD/CAM zirconia superstructure are:

Minimum wall thickness - 0.5 mm;

Minimum post height* for single-unit restorations - 4.5 mm;

Maximum gingival height - 5.0 mm;

Minimum gingival height - 0.5 mm;

Angulation - 0°

and All zirconia superstructures are for straight abutments only.

*Post Height is measured above the gingival height of the final patient-matched design

For the Master Fix, the design parameters for the CAD/CAM zirconia superstructure are:

Minimum wall thickness - 0.5 mm;

Minimum post height* for single-unit restorations - 4.0 mm;

Maximum qinqival height - 5.0 mm:

Minimum gingival height - 0.5 mm;

Angulation - 0°

and All zirconia superstructures are for straight abutments only.

*Post Height is measured above the gingival height of the final patient-matched design

The Ti-Base and Master Fix is compatible with the following implant systems.

#### MR Environment Condition

Non-Clinical worst-case MRI review was performed to evaluated the NB Mini Implant System devices in the MRI environment using scientific rationale and published literature (e.g., Terry O. Woods, Jana Delfino, & Sunder Rajan. (2019). Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices. Journal of Testing and Evaluation 49.2, 783-795), based on the entire system including all variations (all compatible implant bodies, 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.

#### Conclusion

The Subject device and the Primary predicate device have the same intended use, have the same technological characteristics, and are made of the same materials. The Subject device and the Primary predicate device encompass the same range of physical dimensions and are to be sterilized using the same methods. Although there is slightly difference design of the anti-rotation feature, this difference is the same purpose. This minor difference do not impact safety and effectiveness because this difference are related to increase the adhesion of cement to the prosthesis. The data included in this premarket notification demonstrate substantial equivalence to the primary predicate device listed above. Therefore, the subject device and primary predicate device are substantial equivalence.
