• Attributes: Therapeutic

Intended Use

Oneday Implant Abutment is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple unit restorations including; cemented retained, or overdenture restorations, and final or temporary abutment support for fixed bridgework. It is intended for delayed loading. Implants with diameters larger than 5 mm are intended to be used in the molar region.

Device Story

Oneday Implant Abutment system consists of various dental abutments (straight, angled, transfer, healing) and screws; used to support/maintain prosthetic teeth in partially or fully edentulous patients. Device connects to dental fixtures implanted in jawbone; provides interface for final or temporary restorations. Operated by dentists/clinicians in clinical settings. Input is physical connection to dental fixture; output is mechanical support for prosthetic restoration. Benefits include restoration of chewing function and tooth aesthetics. Device is non-sterile; requires end-user sterilization. Clinical decision-making relies on clinician assessment of patient anatomy and prosthetic needs.

Clinical Evidence

No clinical data. Substantial equivalence established via bench testing, including fatigue testing per ISO 14801:2016 and biocompatibility testing per ISO 10993 series. Sterilization validation performed per ANSI/AAMI ST79 and related ISO standards.

Technological Characteristics

Fabricated from Ti-6Al-4V ELI (ASTM F136). Mechanical connection to dental fixtures via internal hex or screw-retained interfaces. Dimensions vary by model (diameters 4-8mm). Non-sterile, end-user sterilization required. No software or electronic components.

Indications for Use

Indicated for partially or fully edentulous patients (mandibles and maxillae) requiring single or multiple unit restorations (cemented, screw-retained, or overdenture) or fixed bridgework support. Intended for delayed loading. Implants >5mm diameter are for molar region use.

Regulatory Classification

Identification

Dear April Lee:

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 (the 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 available 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.

{1}------------------------------------------------

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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 Part 803) for devices or postmarketing safety reporting (21 CFR Part 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 (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products: and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

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

| Comparison | The Subject Device and primary predicate have same characteristics such as<br>indications for Use, general design, diameter, surface treatment, material, abutment<br>connection, and sterilization method. The differences between the two devices are<br>abutment design and length. The differences don't impact product's fundamental<br>technologies; therefore, subject device and predicate device are substantially<br>equivalent. | |
