Intended Use

Nobel Biocare's Zygoma implants are endosseous dental implants intended to be surgically placed in the bone of the upper jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore patient esthetics and chewing function. The Zygoma Implants may be put into immediate function provided that stability requirements detailed in the directions for use are satisfied.

Device Story

NobelZygoma 45° is a threaded, root-form titanium dental implant; designed for surgical placement through the maxillary sinus into the Zygomaticus bone. Device supports prosthetic devices (e.g., artificial teeth) to restore chewing function and esthetics. Used by dental surgeons in clinical settings. Implant features 45° angled external hex connection; TiUnite surface treatment; lengths 30–52.5 mm. Provides stable anchorage in cases of advanced jaw bone resorption. Output is mechanical support for dental prosthetics; clinical decision-making relies on surgeon assessment of bone stability and prosthetic requirements. Benefits include restoration of oral function for patients with insufficient maxillary bone for standard implants.

Clinical Evidence

Bench testing only. Fatigue limit determined using modified ISO 14801 testing comparing subject and predicate devices under identical worst-case conditions. Predicate data leveraged for biocompatibility, sterilization (ANSI/AAMI/ISO 11137), packaging, and shelf-life (5-year expiration).

Technological Characteristics

Material: CP Titanium grade 4. Surface: TiUnite. Connection: 45° angled 4.0 mm external hex. Dimensions: 30–52.5 mm length; 4.5 mm platform diameter. Principle: Endosseous osseointegration. Sterilization: Gamma radiation (ANSI/AAMI/ISO 11137).

Indications for Use

Indicated for patients requiring dental implants in the upper jaw arches to support prosthetic devices for restoration of esthetics and chewing function.

Regulatory Classification

Identification

An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.

Analysis of Differences Between Subject Device and Predicate

The subject NobelZygoma 45° implants have a fundamentally similar design as the predicate Zyqoma Implants (K070182). The two implant designs share the same materials, manufacturing methods, and use the TiUnite surface treatment. The two designs have the same 45° anqulated platform and use the same abutments and surgical tooling. The two designs are available in lengths from 30 to 52.5 mm. The illustrations below show the subject NobelZygoma 45° implant next to the predicate Zygoma Implant.

NobelZvgoma 45°

Image /page/7/Picture/4 description: The image shows a long, silver-colored, cylindrical object that appears to be a screw or bolt. The object has a series of ridges or threads running along its length, and one end has a hole or slot, while the other end is pointed. The screw is likely made of metal and is designed to be inserted into a material to hold it in place.

Zyqoma Implant (K070182)

Although the subject and predicate devices share many similarities, a number of design characteristics have been changed. These changes are listed below.

- -The tip of the NobelZygoma 45° has been modified to a tapered design with flutes to facilitate bone cutting. The predicate Zygoma Implant has a rounded tip with through hole.
- -The threads of the NobelZygoma 45° start at the implant apex and extend 18 mm. The threads of the predicate start 2.8 mm from the apex and extend to the platform.
- -The profile of the NobelZygoma 45° is different from the predicate. Both implants are parallel walled with 2 diameters. The NobelZygoma 45° has a diameter of 4.5 mm at the platform and a diameter of 3.9 mm starting from 2 mm below the platform. The predicate Zygoma Implant is 4.4 mm at the platform and 3.9 mm starting 13.7 mm from the platform

Summary:

These changes were made to modify the implant design to better adapt to situations of advanced jaw bone resorption in which Zygomatic implants are being used. The changes do not raise different questions of safety or effectiveness compared to the predicate. Differences in technology were evaluated through comparative performance testing.

## VII. PERFORMANCE DATA

#### Summary of Non-Clinical Testing:

Since the subject device does not represent a new worst case, data from the predicate device was leveraged in the following aspects of the 510(k).

- -Sterile Device Information
- The sterilization method for the subject device is the same as the o predicate. The sterilization method is Gamma radiation and has been validated in accordance with ANSI/AAMI/ISO 11137. Therefore, no additional testing was required.
- -Device Packaging
- The packaging for the subject device is the same as the predicate. o This is a titanium cylinder placed in a plastic vial with PVC shrinkwrap and tamper resistant strip. Therefore, no additional testing was required.
- Shelf Life
- o The packaging for the subject device is the same as the predicate and is labeled with a 5 year expiration date. Real time aging was used to determine the expiration dating. Therefore, no additional testing was required.
- Biocompatibility -
- The subject device is manufactured from the same material using o the same manufacturing method as the predicate, has the same intended use, and the same patient contact type and duration. Therefore, no additional testing was required.

The fatigue limit of the NobelZygoma 45° was determined using a modified version of ISO 14801. The modifications to ISO 14801 were done to reflect the likely worst-case clinical use of the device. Both the subject and predicate device were tested under identical conditions. The results of the testing were used to address questions related to substantial equivalence based on difference in design between the subject and predicate devices.

### VIII. CONCLUSIONS

The NobelZygoma 45° was evaluated for substantial equivalence using standard and/or comparative testing. In cases where the NobelZygoma 45° could be shown to not represent a worst-case with respect to the Zygoma Implant, data from the predicate device was leveraged to support the subject device. Based on technological characteristics and non-clinical test data included in this submission, the NobelZygoma 45° has been shown to be substantially equivalent to the Zygoma Implant.
