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.

The s-Clean Link Abutment is composed of two-piece abutment that is a link abutment at the bottom, a coping (CAD/CAM patient specific superstructure) at the top and screw. The bottom link abutment portion of the s-Clean Link Abutment is pre-manufactured (stock) made from a titanium alloy conforming to ASTM F136. The Top half of the s-Clean Link Abutment is composed of zirconia conforming to ISO 6872 reference to prior cleared ceramic, K141724. s-Clean Abutment Screw s-Line is made of Ti-6AI-4V ELI (ASTM F136) The diameters of s-Clean Link Abutment are 4.5 and 4.8mm. s-Clean Link Abutment is provided non-sterile therefore must be sterilized after the cementation of the patientspecific superstructure on the Link Abutment. The proposed devices are compatible with the following device. | Dental Implants | | | |-----------------------------------------------|------------------------------------|-----------------------------------------| | Subject Abutment | s-Clean Link Abutment Regular | s-Clean Link Abutment Mini | | Compatible Implants<br>(Knumber) | Dentis s-Clean s-Line<br>(K210134) | Dentis s-Clean s-Line Mini<br>(K210080) | | Implant diameter size | Ø5.8, 6.8 and 7.8 | Ø5.8, 6.8 and 7.8 | | Platform diameter size | Ø4.3, 4.5 | Ø4.3, 4.5 | | Implant Interface Connection<br>Type/Size(mm) | Internal connection type / 2.5Hex | Internal connection type / 2.1Hex | | Type of Implant-Abutment<br>Connection | Hex/Non Hex | Hex/Non Hex | #### Raw material blanks - K141724, Upcera Dental Zirconia Blank & Dental Zircornia Pre-Shaded Blank by Liaoning Upcera ● Co..

The coping that composes the final abutment should be designed and milled through the CAD/CAM software, according to the prosthetic planning and patient clinical situation. The coping and crowns designed using these or more recent versions of the CAD/CAM System, within the design limits as defined within the design software, are compatible with the link abutment. The coping would be manufactured by Dentis only with design input using CAD/CAM Software from and by Dentis milling center. #### Design Limitation for Superstructure: | | Zirconia for s-Clean Link Abutment<br>Regular | Zirconia for s-Clean Link Abutment<br>Mini | |-------------------------------------------------------------|-----------------------------------------------|--------------------------------------------| | Minimum wall thickness | 0.5 | 0.5 | | Minimum/Maximum Post Height for<br>single-unit restorations | 4.45 | 4.45 | | Maximum gingival height in the<br>zirconia superstructure | 0 | 0 | | Minimum gingival height in the Link<br>Abutment | 1 | 1 | | Maximum angulation | 0 | 0 | {5}------------------------------------------------ ## Summaries of Technology Characteristics The subject device is substantially equivalent to the current cleared devices.

The results of the above tests have met the criteria of the standard and demonstrated substantial equivalence with the predicate device. Non-clinical testing was conducted in accordance with FDA Guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments". 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, and the result report is attached. ## MR Environment Condition Non-clinical worst-case MRI review was performed to evaluate the metallic s-Clean Link Abutment 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 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 The s-Clean Link Abutment 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 its predicate device. Therefore, s-Clean Link Abutment and its predicates are substantially equivalent
