AI/ML (Artificial Intelligence / Machine Learning)

No
The summary describes a standard dental implant system component (healing abutment) made of titanium. There is no mention of AI, ML, image processing, or any software-driven features that would suggest the use of these technologies. The performance studies focus on risk analysis and biocompatibility, not algorithmic performance.

Therapeutic

Yes
The device is intended to restore the patient's chewing function by providing support for prosthetic devices, which aligns with the definition of a therapeutic device designed to treat or alleviate a medical condition.

Diagnostic

No
The Luna Dental Implant System is intended for surgical placement to support prosthetic devices and restore chewing function, not for diagnosing medical conditions.

SaMD (Software as a Medical Device)

The device description explicitly states it is a "Healing Abutment" made of "commercially pure titanium alloy Gr4," indicating it is a physical hardware component, not software.

IVD (In Vitro Diagnostic)

Based on the provided information, the Luna Dental Implant System is not an IVD (In Vitro Diagnostic) device.

Here's why:

Intended Use: The intended use clearly states that the device is surgically placed in the bone to support prosthetic devices and restore chewing function. This is a direct therapeutic intervention within the body.
Device Description: The description details a physical implant system made of titanium alloy, designed for surgical placement and healing within the oral cavity.
Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Luna Dental Implant System does not interact with or analyze such specimens.

The device is a medical device, specifically a dental implant system, but it falls under the category of devices used for treatment and restoration within the body, not for in vitro diagnostic testing.

Device Description

The Luna Dental Implant System 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, and to restore the patient's chewing function. This submission is to get clearance on the modification of the healing abutments that are used with the fixture cleared under K123155 and K160106.

The healing abutment is to be connected to the implant and is to heal gingiva before setting abutment on the implant in the oral cavity. It is made of commercially pure titanium alloy Gr4. It offers narrow and regular platform types, and the narrow type has anodizing surface treatment in purple to be distinguished from the regular type.

Dear Priscilla Chung:

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 (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 located 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

7. Basis for Substantial Equivalence

The Luna Dental Implant System - Healing Abutment is substantially equivalent to its predicate device (K123155) in terms of indications for use, raw material, and design. The differences are in body design and size range. The design change does not raise a question in substantial equivalence since the change is not significant. We have identified a reference device that encompass the size range of the subject device. Based on the information submitted here in we conclude that the subject device is substantially equivalent to the predicate devices.
