#### Summary of Subject Device Multi-Unit Abutment Designs

The design dimensions and tolerances of subject device abutments and screws have been established on the basis of a contractual agreement and working relationship between Implant Direct and Terrats Medical SL to ensure that the abutments are designed to fit the corresponding Implant Direct implants listed above.

### Multi Unit Abutments

The Multi-Unit Abutment is designed for attachment of multi-unit screw-retained restorations and is provided in three (3) designs, straight, angled 17°, and angled 30°. The design of the straight Multi-Unit Abutments is similar to that of straight Multi-Unit Abutments cleared in K222269 with the exception of the implant connections and platform diameters. The straight Multi-Unit Abutment is provided only in a non-engaging, threaded design that attaches directly to the implant. All straight Multi-Unit Abutments are provided with a prosthetic platform diameter of 4.8 mm. Straight Multi-Unit Abutments are provided for Implant Direct internal hex implants with 3.5 mm and 4.5 mm platform diameters, and for Implant Direct internal conical implants with 3.0 mm platform diameters. The gingival height of the straight Multi-Unit Abutment ranges from 1.5 mm to 5.5 mm.

The angled Multi-Unit Abutments are provided in an engaging design that requires an abutment screw, with angulations of 17° and 30°. The angled Multi-Unit Abutments are provided for the same Implants as the straight Multi-Unit Abutments (internal hex implants with 3.5 mm platform diameters, and internal conical implants with 3.0 mm and 3.4 mm platform diameters). All angled Multi-Unit Abutments are provided with a prosthetic platform diameter of 4.8 mm, and with gingival heights from 2.5 mm. The designs of the angled Multi-Unit Abutments are similar to those of the angled Multi-Unit Abutments cleared in K222269. All Multi-Unit Abutments are manufactured from titanium alloy (Ti-6Al-4V) conforming to ASTM F136.

#### Screws

This submission includes three (3) abutment screws to be used with the subject device abutments. The screws have a hex or hexalobular instrument interface and are manufactured from titanium alloy (Ti-6A1-4V) conforming to ASTM F136.

{6}------------------------------------------------

## PERFORMANCE DATA

Non-clinical data submitted, referenced, or relied upon to demonstrate substantial equivalence included:

sterilization validation according to ISO 17665-1 and ISO 17665-2, referenced from K22269;

biocompatibility according to ISO 10993-5 and ISO 10993-12, referenced from K22269;

non-clinical analysis performed to evaluate the metallic subject devices and compatible dental implants in the MR environment using scientific rationale and published literature (TO Woods, JG Delfino, and S Rajan, "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices," Journal of Testing and Evaluation, Volume 49, No. 2, 2021, pp. 783-795); the analysis addressed parameters per the FDA guidance Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment (issued May 2021) including magnetically induced displacement force and torque; and

static compression and compression fatigue testing of worst-case constructs comprising the subject device Multi Unit Angled Abutments and compatible OEM implants in conformance with ISO 14801.

No clinical data were included in this submission.

## EQUIVALENCE TO MARKETED DEVICES

The subject device abutments are substantially equivalent in intended use to the primary predicate device K222269. All are intended for use with endosseous dental implants in the maxilla and mandible to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible. The Indications for Use Statement (IFUS) for the subject device is substantially equivalent to that of K222269, except for the list of compatible OEM implants. An additional difference between the IFUS of the subject device and that of the primary predicate K22269 is the language in K22269 describing the requirement of a validated milling center for CAD-CAM abutments. This language is not applicable to the subject device abutments. All reference devices identified are for OEM implant body compatibilities.

The range of dimensions of the subject device abutment-implant platform diameter, prosthetic platform diameter, gingival height, and abutment angulation, is encompassed by the corresponding multiunit abutments in the primary predicate device K222269.

All subject device components are provided non-sterile and are to be sterilized by the same moist heat cycle recommended in the primary predicate K222269. The subject devices are packaged in either a PETG blister pack or a PET bag, the same packaging as cleared in K222269.

The risks associated with use of the subject device angled multi-unit abutments in combination with the compatible implants are mitigated by mechanical testing performed according to ISO 14801.

#### CONCLUSION

The subject device, the primary predicate device, and the reference devices have the same intended use, have similar technological characteristics, and are materials. The subject device and the primary predicate device encompass the same range of physical dimensions, are packaged in similar materials, and are to be sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
