The subject device and the primary predicate encompass the same range of physical dimensions, are packaged in similar materials, and are to be sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the primary predicate listed above. {8}------------------------------------------------ ### Non-clinical Testing #### MR Environment Condition Non-clinical worst-case MRI review was performed to evaluate the metallic SIMDA abutment 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. Non-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalen ce included: - · Fatigue testing followed ISO 14801 and the FDA special controls guidance document. - · End User Steam Sterilization Test according to ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010. - · Biocompatibility tests according to ISO 10993-1:2009. ISO 10993-5:2009. and ISO 10993-10:2010. Non-clinical test data was used to evaluate the proposed device's substantial equivalence compared to the primary predicate. The results of the above tests have demonstrated the substantial equivalence with the primary predicate. 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'', and it consisted of testing finished assembled implant/abutment systems of the worstcase scenarios through fatigue testing. Dimensional analysis and reverse engineering of critical features of critical features and tolerances of the implant-to-abutment connection platform were performed on the OEM implant body, the OEM abutment, and the OEM abutment screw. Cross sectional images wre provided to demonstrate substantially equivalent compatibility. The testing aided implant to abutment compatibility and has established substantial equivalency of the proposed device with the predicate devices. Clinical testing was not necessary to establish substantial equivalency of the device. {9}------------------------------------------------ Image /page/9/Picture/0 description: The image shows the word "SIMDA" in a bold, sans-serif font.

The minor differences between the subject device and the primary predicate device are related to the compatible OEM implant lines and the implant platform diameter. |

design parameters are as follow. The minimum diameter of the product compatible with the subject device is larger than the primary predicate device. The diameter of the primary predicate device is Ø8mm~ Ø10mm, while the subject device can be designed from Ø 5.0mm up to Ø8.0mm. The angle of the reference device is 0~20°, while the subject device can be designed up to 15°.
