The logo consists of the letters "DIO" in a bold, sans-serif font. The "DI" is in gray, while the "O" is in pink and has a small pink circle above and to the right of it. Below the letters, in a smaller font, are the words "Implant Solution". The subject device is a two-piece abutment. It consists of Eco Base abutment and 3 types of post (Cemented, Angled and Temporary). The subject device has the same indications for use compared to the predicate device (K161655) and design (except for its shape), identical material composition and manufacturing methods by the same manufacturer compared to the reference device (K182194). The Indications for Use Statement has minor differences; however has the same intended use as being used with Endosseous dental implant to support a single or multiple prosthetic devices. #### Differences The diameter and lengths are different compared to the predicate device; however, the 4.5~6.5mm for the subject device and 4.8, 5.3 and 6.5mm for the predicate devices is comparable. The total length of 5.5 to 14.5 mm for the subject device is an extended range compared to the predicate devices. To account for these differences, fatigue testing was conducted in accordance with ISO 14801 to verify that subject device is substantially equivalent to the predicate devices. The results of fatigue testing were comparable between the predicate and subject device. #### Discussion The subject device is similar in fundamental scientific technology to the predicate device (K161655) in that they have been designed in compliance with FDA's Class II special controls guidance document root-form Endosseous dental implants and Endosseous dental implant abutment. There are slight mechanical differences between subject devices which was evaluated through comparative performance testing. The documentation submitted in the premarket notification demonstrates that the subject device is substantially equivalent to the predicate devices. Therefore, we conclude that the Eco Base abutment is substantially equivalent to the predicate device. {8}------------------------------------------------ Image /page/8/Picture/1 description: The image shows the logo for DIO Implant Solution.

The Indications for Use Statement has minor differences; however has the same intended use as being used with Endosseous dental implant to support a single or multiple prosthetic devices. #### Differences The subject device is substantially equivalent to the indication for use, connected fixture type, design and angle as compared to the predicate devices, but includes additional specifications in order to cover different clinical situations. The subject device has additional cuff sizes as compared to the predicate devices. To account for these differences, fatigue testing was conducted in accordance with ISO 14081 to verify substantial equivalence with the predicate device. The results of the fatigue testing were comparable between the predicate and subject device. #### Discussion There are slight mechanical differences between the subject devices. These differences were evaluated through comparative performance testing. The documentation submitted it the premarket notification demonstrates that the subject device is substantially equivalent to the marketed devices. Therefore, we conclude that the Multiunit abutment is substantially equivalent to the predicate device. {10}------------------------------------------------ Image /page/10/Picture/1 description: The image shows the logo for DIO Implant Solution.

Summary of Non-clinical Testing The results of the non-clinical testing demonstrate that the results have met the criteria of the standards, and the subject device is substantially equivalent to the predicate device. ## Sterilization Validation The subject device is provided non-sterile. Sterilization has been performed in accordance with ISO 17665-1 and ISO 17665-2 for steam sterilization. Test results have demonstrated that the SAL of 10-6 was achieved and all testing requirements were met. Also, Sterilization Validation was conducted according to FDA Guidance "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling". ## Biocompatibility Biocompatibility tests were conducted in accordance with 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" and ISO 10993-10, ISO 10993-10, ISO 10993-23, ISO 10993-11, ISO 10093-3, and ISO 10993-6. The Abutments have the identical nature of body contact, contact duration, material formulation, manufacturing processes, and sterilization methods compared to the reference devices, K182194 and K080559. No new issues of biocompatibility are raised for the subject devices. ## Mechanical Properties Fatigue testing was performed on the subject device including both the eco abutments and multiunit abutments in accordance with ISO 14801:2016 Dentistry-Implants-Dynamic fatigue test for Endosseous Dental Implants. The worst case scenario was chosen based on the FDA guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments". Comparative fatigue testing was also performed on comparative abutments cleared in K182194. ## MR Environment Condition Non-clinical worst-case MRI review was performed to evaluate the metallic. Eco Abutment and Multiunit Abutment in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry 0., 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 bodied, 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. {11}------------------------------------------------ Image /page/11/Picture/1 description: The image shows the logo for DIO Implant Solution.

Below the letters is the text "Implant Solution" in a smaller, gray, sans-serif font. ## 7. Summary of Clinical Testing No clinical studies are submitted. ## 8. Conclusions The Eco Abutment and Multiunit Abutment constitute a substantially equivalent medical device, meeting all the declared requirements of its intended use. These abutments have the same intended use and fundamental scientific technology as its predicate device. Therefore, Eco Abutment and Multiunit Abutment and its predicates are substantially equivalent. End of Document
