Intended Use

EK DIGITAL ABUTMENTS are intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures.

Device Story

EK Digital Abutments are patient-specific dental abutments designed for use with Hiossen EK dental implants. They function as an interface between the endosseous implant and the final prosthetic restoration (crown, bridge, or overdenture). The device is manufactured from titanium alloy (ASTM F136) or titanium alloy combined with zirconia. Hybrid versions consist of a titanium base and a CAD/CAM patient-matched mesostructure, bonded with dental cement. Clinicians prescribe these abutments based on patient-specific anatomy. The device is provided non-sterile and requires steam sterilization by the user prior to clinical placement. By providing a stable connection to the implant, the abutment supports the prosthetic restoration, facilitating functional and aesthetic dental rehabilitation. The device is used in a clinical dental setting by a licensed dentist.

Clinical Evidence

No clinical performance data was submitted. Substantial equivalence is supported by non-clinical bench testing, including mechanical fatigue testing conducted in accordance with ISO 14801. The device successfully withstood 5,000,000 cycles without failure at loads equivalent to the primary predicate.

Technological Characteristics

Materials: Titanium alloy (ASTM F136) and Zirconium oxide (ISO 6872). Design: Patient-specific, CAD/CAM manufactured. Connection: Internal hex or non-hex. Sterilization: Steam sterilization (ISO 17665-1). Connectivity: None (mechanical component).

Indications for Use

Indicated for patients requiring support for screw-retained single restorations or cement-retained single or multi-unit dental prosthetic restorations (crowns, bridges, overdentures) using Hiossen EK dental implants.

#### 6.7 Non-Clinical Performance Data

Non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence include data from the following tests:

#### Biocompatibility Testing

The EK Digital Abutment are manufactured using the same manufacturing process and same well known and well-established material as the predicate device; therefore, we reason it was not necessary to re-test biocompatibility in order to support the biological safety of the EK Digital Abutment. Furthermore, as described in International Standard Organization (ISO) standard ISO-10993, Biological Evaluation of Medical Devices Part 1: Evaluation and Testing when a new material is used that has not been identified in a primary predicate device. The proposed devices are manufactured from standard raw material that are used in the primary predicate devices and other currently marketed dental implant and abutment system. Therefore, no additional biocompatibility testing is required to establish substantial equivalence.

#### Sterilization Validation

The EK Digital Abutment are manufactured by the predicate device manufacturing process, material and utilizes the same packing materials) are not sterilized like the predicate devices listed in this submission. Like the predicate devices the proposed can be moist heat sterilized and was validated following ISO 17665-1 [2006] Sterilization of health care products - Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices, therefore we reason it was not necessary to re-test validation in order to support sterilization validity of the EK Digital Abutments.

#### Shelf Life

The EK Digital Abutment like the predicate listed in this submission do not have a stated shelf life. The proposed devices are non-sterile and use the same exact packaging materials, manufactured from medical grade titanium alloy which are non-mechanical, non-active materials therefore, degradation in performance characteristics is not likelv.

#### Surface Treatment Characterization Testing

The EK Digital Abutment are manufactured by the predicate device manufacturer, with surfaces using the same manufacturing process, material and surface finishing as the predicate devices listed in this submission. No additional character testing was necessary to support the equivalency of the EK Digital Abutments.

Image /page/9/Picture/0 description: The image shows the Hiossen Implant logo. The word "Hiossen" is written in a stylized font, with the "H" in red and the rest of the letters in gray. The word "Implant" is written in smaller gray letters below the word "Hiossen". The logo is simple and modern.

#### Mechanical Properties

The EK Digital Abutment System Mechanical testing was conducted in accordance to ISO 14801 Dentistry -Fatique Test for Endosseous Dental Implants. The worst case implant and titanium abutments chosen for the tests were the smallest diameter implant loaded with abutments with the greatest angulation. The test articles were able to withstand 5,000,000 cycles without failure at a substantially equivalent load to the primary predicate.

#### 6.8 Clinical Performance Testing

No clinical performance report(s) is being submitted.

#### 6.9 Conclusion

In accordance with the Federal Food Drug and Cosmetic Act, 21 CFR Part 807, and based on the information provided in this premarket notification, HIOSSEN, INC. concludes since the EK Digital Abutment has the same design, intended use, structure, diameters, lengths, material surface, sterilization and packaging as the predicate devices listed in this submission are substantially equivalent. The propose devices do not pose any new or increased risk as compared to both the legally marketed predicate and reference devices.
