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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

Shelf Life Test for SAVE Wide Cap according to ASTM F1980 referenced in K171027 - . End User Sterilization Validation Test Report for Abutments made with Ti-6Al-4V ELI according to ANSVAAMI ST79, ISO 17665-1,-2, ISO 11737-1,-2, and ISO 11138-1 referenced in K111364 - End User Sterilization Validation Test Report for Abutments made with PEEK, POM and CP Titanium Grade 4 according to ANSI/AAMI ST79, ISO 17665-1,-2, ISO 11737-1,-2, and ISO 11138-1 - . Biocompatibility testing for subject Abutments according to ISO 10993-1:2009 referenced in K171027, K171694, and K222913 The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the predicate device. Gamma sterilization test was performed for our other device. Healing Abutment (DSHZ7890C) as test specimen and leveraged for the subject device because material, manufacturing process, sterilization and packaging of both products are exactly same. The end user sterilization test was performed for the predicate device K171027 and reference device K111364 and leveraged for the subject device because the product category, material, manufacturing process, facility, and packaging of the both products are exactly same. For other subject devices made with other materials as POM, PEEK and Pure Titanium Gr4, the end user sterilization validation reports are provided. The Biocompatibility Test was conducted on the predicate device and leveraged for the subject device because both products are manufactured with same materials and manufacturing process. It demonstrates that the subject device is biocompatible and substantial equivalence with the predicate. The non-clinical testing results demonstrate that the subject device is substantially equivalent to the predicate device. ## Conclusion Dentis s-Clean Regular 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 devices. Therefore, s-Clean Regular Abutment and its predicates are substantially equivalent.
