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).

The results demonstrated the subject devices do not introduce a new worst case compared to the primary predicate and reference devices. In addition to testing on subject device, dynamic fatigue testing was leveraged from the primary predicate (K201491). Torsion tests were performed to evaluate the strength of the screw supplied with all subject abutments against maximum twisting forces. The results proven that there is an adequate torsion strength according to the installation torque indicated in IFU. #### Biocompatibility Testing A biological assessment was performed according to ISO 10993-1 "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process" and to the FDA Guidance document "Use of International Standard ISO 10993- 1, "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process'. Guidance for Industry and Food and Drug Administration Staff, Document issued on: June 16, 2016" for each subject device. The subject devices are identical in material and manufacturing processes to the primary predicate and reference devices, therefore, no new issues regarding biocompatibility were raised and no additional biocompatibility testing was required. #### Sterilization Validation and Packaging The subject devices are provided sterile via Ethylene Oxide (EO) method, validated to a sterility assurance level (SAL) of 106 in accordance with ISO 11135:2014, "Ethylene Oxide – Part 1: Requirements for development, validation and routine control of a sterilization process for medical devices". EO sterilization residuals have been verified to be less than the maximum allowable limits as defined in ISO 10993-7 "Biological Evaluation of Medical Devices - Part 7: Ethylene Oxide Sterilization Residuals". The packaging and sterilization of the subject device are identical to the packaging and sterilization of the primary predicate devices. {15}------------------------------------------------ # Neodent Implant System - Zirconia Implant System ### 510(k) Summary K231803 Steam sterilization has been validated according to ISO 17665-1 "Sterilization of health care products - Moist heat - Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices", using the parameters described in IFU, which are identical to the parameters validated for the primary predicate and reference devices. The devices will not be marketed as non-pyrogenicity information provided is based on FDA Guidance on "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submission for Devices Labeled as Sterile, issued on 21 January 2016." The method used to determine the device meets pyrogen limit specifications is LAL Endotoxin Analysis with testing limit of 20 EU/device, based on a blood contacting and implanted device. #### Conclusion The documentation submitted in this premarket notification demonstrates the subject devices are substantially equivalent to the primary predicate and reference devices.
