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.

Special Controls

*Classification.* (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2) *Classification.* Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use; (ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads; (iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system; (iv) The device must be demonstrated to be biocompatible; (v) Sterility testing must demonstrate the sterility of the device; (vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment; (vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians; (viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and (ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.

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.

The subject device was tested to evaluate its substantial equivalence according to the following standards.

- Bacterial Endotoxin Test Report on Subject Fixture according to ANSI/AAMI ST72:2011, USP ● <161>, and USP <85>
- . Shelf Life Test for subject fixtures according to ASTM F1980

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

- . Sterilization Validation Test for subject fixtures according to ISO 11137-1,2,3 referenced in K153639
- Sterilization Validation Test on s-Clean Healing Abutment for subject Cover Screw according ● to ISO 11137-1,2,3 referenced in K171027
- Shelf Life Test on s-Clean Healing Abutment for subject Cover Screw according to ISO ● 11137-1,2,3 referenced in K171027
- End User Sterilization Validation Test Report for subject abutments according to ANSI/AAMI . ST79, ISO 17665-1, ISO 17665-2, ISO 11737-1, ISO 11737-2, and ISO 11138-1 referenced in K171027
- Biocompatibility testing according to ISO 10993-1:2009, ISO 10993-3:2014, ISO 10993-. 5:2009, ISO 10993-6:2007, ISO 10993-10:2010 and ISO 10993-11:2006 on fixtures referenced in K153639
- . Biocompatibility testing according to ISO 10993-1:2009 on machined surface abutments referenced in K171027.
- . Biocompatibility testing according to ISO 10993-3:2014. ISO 10993-5:2009. ISO 10993-10:2010, and ISO 10993-11:2006 ISO on s-Clean TiN Coating Abutments in K171694
- . Biocompatibility Testing according to ISO 10993-1:2009 on Cover Screw referenced in K171027.

The results of the above tests have met the criteria of the standards, and demonstrated the substantial equivalence with the predicate device. The fatigue testing per ISO 14801 was not conducted as it is not necessary based on the device-specific guidance document

The non-clinical testing results demonstrate that the subject device is substantially equivalent to the predicate device.

### Conclusion

s-Clean SQ-SL Implant System Regular constitutes a substantially equivalent medical device. This system has the same intended use and fundamental scientific technology as its predicate devices. Any additional small differences do not impact substantial equivalence. Therefore, s-Clean SO-SL Implant System Regular and its predicates are substantially equivalent.
