The device description and performance studies focus on the physical characteristics and clinical outcomes of dental implants, with no mention of AI or ML technology.
Yes.
The device, Zygomatic Implants, is designed to restore patient esthetics and chewing function in cases of severe jaw resorption, which directly addresses a health-related condition.
No
Explanation: The device described is a Zygomatic Implant, which is a surgical implant designed to restore patient esthetics and chewing function in cases of severe jaw resorption. It is a therapeutic device, not a diagnostic one.
No
The device description clearly outlines physical components made of titanium, including implants, abutments, and protection cylinders. It also details sterilization methods for these physical components. There is no mention of software as the primary or sole component of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended to be used in vitro for the examination of specimens, including blood, tissue, and urine, from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
- Device Description and Intended Use: The description clearly states that this device is a surgical implant designed for placement into the zygomatic bone to restore patient esthetics and chewing function. It is a physical device implanted into the body, not used to test samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, providing diagnostic information based on laboratory tests, or any other activity typically associated with IVDs.
Therefore, this device falls under the category of a surgical implant, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
Zygomatic Implants are indicated for surgical installation in the zygoma region, in cases of severe jaw resorption, in order to restore patient esthetics and chewing function. Zygomatic Implants are recommended for the posterior (pre-molar/ molar) region, one implant on each side, with at least two standard dental implants in the anterior region to support a fixed restoration. Zygomatic Implants may be loaded immediately when stability is achieved and with appropriate occlusal loading.

Device Description
This submission includes threaded root-form dental implants designed for placement into the zygomatic bone with either an external hexagon abutment interface, or a Morse taper abutment interface. Both implant designs are provided with a thread major diameter of 4.4 mm at the coronal end of the implant (over a length of 10 mm), which tapers to a thread major diameter of 3.9 mm for the remaining implant length. Both implant designs are provided in multiple threaded lengths ranging from 30 mm to 52.5 mm. All implants are made of commercially pure titanium, Grade 4, conforming to ASTM F67, Standard Specification for Unalloyed Titanium for Surgical Implant Applications (UNS R50250, UNS R50400, UNS R50550, UNS R50700).
This submission includes transepithelial abutments with external hexagon or Morse taper interfaces for connection to the zygomatic implants. The external hexagon abutments have a platform diameter of 4.1 mm and are provided in gingival heights of 3, 4, or 5 mm. The Morse taper transepithelial abutments also have a platform diameter of 4.1 mm and are provided in gingival heights of 1.5, 2, 3, 4, or 5 mm.
This submission also includes a Protection Cylinder that is used to protect the abutment during healing of the gingival tissue. The Protection Cylinder may be installed on either abutment design (external hexagon or Morse taper) with the corresponding Protection Cylinder Screw.
All transepithelial abutments, external hexagon transepithelial abutment screws, protection cylinders, and protection cylinder screws are made of titanium alloy conforming to ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401).
All zygomatic implants are packaged assembled with the corresponding implant mount and provided sterilized by gamma irradiation. All transepithelial abutments, external hexagon transepithelial abutment screws, protection cylinders, and protection cylinder screws are provided sterilized by exposure to ethylene oxide.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical data submitted, referenced, or relied upon to demonstrate substantial equivalence include: biocompatibility, engineering analysis, dimensional analysis, and dynamic compressionbending testing according to ISO 14801 Dentistry - Implants - Dynamic fatigue test for endosseous dental implants.
Clinical literature data were submitted in this premarket notification including reports of 45 subjects treated with a total of 90 predicate device (K070182) zygomatic implants in combination with 165 conventional dental implants, and 16 subjects treated with a total of 37 subject device zygomatic implants in combination with 58 conventional dental implants. All subjects were treated for rehabilitation of maxillary atrophy for restoration of aesthetics and chewing function. The subjects who received the predicate zygomatic implants were treated by a delayed loading protocol in 44 of 45 cases (1 case of immediate loading); all subjects who received the subject device zygomatic implants had immediate loading (within 48 hours of surgical placement). Follow-up time periods for all subjects ranged from 6 to 36 months. For the subjects who received the predicate zygomatic implants, survival of the zygomatic implants was 100% and survival of the conventional implants ranged from 85.7 to 100%. Subjects who received the subject device zygomatic implants had 100% survival of all implants (zygomatic and conventional) after immediate loading at 12 months. These clinical data demonstrate the subject device is as safe, as effective and performs as well as the predicate device in the atrophic maxilla.

The subject device and the primary predicate K070182 have substantially equivalent indications for use, including restoration of patient esthetics and chewing function, and immediate loading when used with standard dental implants placed in the anterior region to support a fixed restoration. The implants of the subject device and the predicate device K070182 have similar designs, dimensions, materials, and machined surface finish. The abutments of the subject device have similar designs, similar dimensions, and are made from similar or identical materials as those cleared under K070182, K133510, and K123022. The subject device includes both external hexagon and Morse taper abutment-implant interface connections, whereas the K070182 predicate device includes only external hexagon connections. The subject device includes only straight abutments, whereas the K070182 predicate device abutments are provided in both straight and 17° angled designs. The subject device external hexagon abutments are provided in gingival heights of 3, 4, and 5 mm, whereas the K070182 predicate device external hexagon abutments are provided in gingival heights of 2, 3, and 5 mm.
The subject device has similar packaging and is sterilized using the same materials and processes as the predicate devices in K133510, and K123022.
CONCLUSION
The subject device and the predicate devices have intended use, have similar technological characteristics, and are made of similar materials. The subject device and predicate devices encompass the same range of physical dimensions, including diameter and length of the implants, and diameter, gingival height, and angle of the abutments. The subject and predicate devices are packaged in similar materials and sterilized using similar methods.
The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
