The subject abutments are equivalent with regard to nature of body contact, duration of use, material formulation and sterilization methods compared to the primary and reference predicate devices and therefore, no new testing have been performed as biocompatibility is represented in the primary and reference predicate devices. In support of the subject PMMA plastic copings, Cytotoxicity testing according to ISO 10993-5:2009, "Biological evaluation of medical devices – Part 5: Test for in vitro cytotoxicity" and Chemical Analysis according to ISO 10993-18: 2020 "Chemical characterization of medical device materials within a risk management process" has been performed. In addition to the above testing a toxicology evaluation has been performed in support of the subject PMMA plastic copings. The test and evaluation performed the biocompatibility of the subject PMMA plastic copings. #### Sterilization The subject device are single patient devices. The Immediate Temporary Abutments will be delivered in a sterile packaging via Gamma Irradiation and the PMMA plastic coping will be delivered non-sterile. The PMMA plastic coping is to be manually cleaned and disinfected according to the Instructions for Use. A sterilization validation assessment was performed according to ISO 11137 for the Immediate Temporary Abutments. The assessment concluded the proposed Immediate Temporary {10}------------------------------------------------ ## Straumann® Immediate Temporary Abutments ### 510(k) Summary Abutment can be adopted into the same sterilization process validated for the Straumann Sterile Prosthetics cleared for reference predicate K192401. A high-level disinfectant validation was performed on the worst case PMMA device. The worst case was selected based on the most challenging designs for high level disinfection process due to size, surface, complexity and accessibility of the liquid solution. The subject PMMA Plastic Coping is not considered a new worst case and therefore can adopt the validation demonstrating the high-level disinfectant cleaning method can effectively disinfect the Plastic Coping. The packaging of the Straumann® Immediate Temporary Abutments is identical to the packaging of the reference device K192401. There are no changes to the sterilization method or production process compared to the reference device. The shelf life for the proposed devices is 5 years identical to the reference device. #### Bench Testing The subject devices are MRI Conditional and do not introduce a new material or worst-case scenario and is represented under reference device K190662. #### Conclusion 5.8 The documentation submitted in this premarket notification demonstrates the subject devices are substantially equivalent to the primary predicate and reference devices.
