Intended Use

Dentis i-Clean System is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple unit restorations including; cemented retained, screw retained, or overdenture restorations, and terminal or intermediate abutment support for fixed bridgework. This system is dedicated for one and two stage surgical procedures. This system is intended for delayed loading.

Device Story

The Dentis i-Clean System is a dental implant abutment system used in prosthetic restoration. It comprises various abutments (angled, temporary, CCM UCLA, Octa CCM cylinder) and fixation screws. The device connects to dental fixtures to support dental prostheses. It is used in clinical settings by dental professionals. The system is provided non-sterile and requires steam sterilization by the end-user before placement. The device functions as a mechanical interface between the implant fixture and the final restoration, facilitating tooth function restoration. It is intended for delayed loading protocols.

Clinical Evidence

No clinical data. Substantial equivalence is supported by bench testing, including fatigue testing per ISO 14801:2016, sterilization validation per ISO 17665-1/-2 and ISO 11737-1, and scientific rationale/literature review for MRI safety assessment.

Technological Characteristics

Materials: Ti-6Al-4V ELI (ASTM F136), PEEK (ASTM F2026), and Chrome-cobalt-molybdenum (ISO 5832) with Acetal (POM). Components include angled, temporary, and CCM abutments with associated screws. Dimensions vary by model with ±1% tolerance. Non-sterile, end-user steam sterilized. Mechanical connection to dental fixtures.

Indications for Use

Indicated for partially or fully edentulous patients (mandibles and maxillae) requiring single/multiple unit restorations (cemented, screw-retained, or overdenture) or fixed bridgework support. Dedicated for one and two-stage surgical procedures with delayed loading.

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 (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.

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

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 (QS) 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).

# Non-Clinical Test Data

Below tests were performed on subject device:

- Fatigue Testing under the worst-case scenario according to ISO 14801:2016 ●
- . End user Sterilization Validation for Abutment made of PEEK and CCM materials according to ISO 17665-1,-2, and ISO 11737-1.

Below tests were performed for predicate devices and leveraged for the subject device:

- . End User Sterilization Validation for Abutments made of Ti-6AI-4V ELI according to ISO 17665-1,-2, and ISO 11737-1 referenced in K111364
- Biocompatibility testing on Abutments made of Ti-6Al-4V ELI according to ISO 10993-1:2009 referenced in K171027 and K150344
- . Biocompatibility testing on Abutments made of PEEK and CCM according to ISO 10993-1:2009 referenced in K171027

The Fatigue Testing was performed under the worst-case scenario according to ISO 14801:2016.

For all subject devices delivered non-sterile to be end-user sterilized, the recommended sterilization has been validated according to ISO 17665-1 and ISO 17665-2 and to applicable recommendations in the FDA guidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, issued on March 17, 2015". The worst-case construct was tested.

The Biocompatibility test was conducted on the predicate device and leveraged for the subject device because both products are manufactured with the same materials and manufacturing process. It demonstrates that the subject device is substantially equivalent with the predicate.

# MR Environment Condition

Non-clinical worst-case MRI review was performed to evaluate the metallic devices in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry O., Jana G. Delfino, and Sunder Rajan. "Assessment of Magnetically Induced Displacement Force and Torque on Metal

{9}------------------------------------------------

Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795), based on the entire system including all variations (all compatible implant bodies, dental abutments, and fixation screws) and material composition.

Rationale addressed parameters per the FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment," including magnetically induced displacement force and torque.

Clinical testing was not necessary to establish substantial equivalency of the device.

## Conclusion

Dentis i-Clean System constitutes a substantially equivalent medical device, meeting all the declared requirements of its intended use. This system has the same intended use and fundamental scientific technology as predicate device. Therefore, Dentis i-Clean System and its predicate are substantially equivalent.
