## Substantial Equivalence Discussion
TruBase S consists of a two-piece abutment, where the titanium base is a pre-manufactured abutment that will be used to support a CAD/CAM-designed superstructure (the second part of the two-piece abutment) that composes the final abutment.
The subject device is substantially equivalent in indications and design principles to the primary predicate device and the reference devices listed above. Provided tables are comparing the Indications for Use Statements and the technological characteristics of the subject device and the primary predicate device.
The Indications for Use Statement (IFUS) for the subject device (TruBase S) is substantially equivalent in intended use to the primary predicate device (K201197). All are intended for use with endosseous dental implants in the maxilla and mandible to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible.
The Indications for Use Statement (IFUS) for the subject device (TruBase S) is substantially equivalent to that of the primary predicate device (K201197). Slight differences in the language of the subject device and primary predicate device Indications for Use statements do not affect the intended use as an endosseous dental implant abutment for support of a prosthesis to restore chewing function.
The other minor differences are related to the compatible OEM implant lines. None of these minor differences impact substantial equivalence because all IFUS express equivalent intended to use to facilitate dental prosthetic restorations, and the indications are expressed equivalently using different specific wording.
Also, the primary predicate device follows the same digital workflow and utilizes the same materials (Ti-6Al-4V ELI) and inCoris ZI, as the subject device system.
| Design parameter | Subject Device<br>(K201842) | Predicate Device<br>(K201197) |
|-----------------------------------------------------------------------------|-----------------------------|-------------------------------|
| Minimum and Maximum<br>abutment angle (°) | 0~15 | 0~15 |
| Minimum and Maximum<br>Cuff Height (mm) | 0.5~5.0 | 0.5~5.0 |
| Minimum and Maximum<br>diameter at<br>abutment/implant interface<br>(Ø, mm) | 5.0~8.0 | 5.0~8.0 |
The subject device and the predicate device design parameter are substantially equivalent.
{12}------------------------------------------------
Image /page/12/Picture/0 description: The image shows a logo for a company called "Abutment". The logo is in blue and white, with the word "Abutment" in a sans-serif font. The logo also includes a stylized image of a screw or bolt. The logo is simple and modern, and it is likely used to represent a company that manufactures or sells screws, bolts, or other fasteners.
| Design parameter | Subject Device<br>(K201842) | Predicate Device<br>(K201197) |
|-----------------------------------------------------------------------------------------------------------------|-----------------------------|-------------------------------|
| Minimum Thickness (mm) | 0.4 | 0.4 |
| Minimum and Maximum<br>length of abutment post<br>(length above the abutment<br>collar/gingival height)<br>(mm) | 4.0~6.0 | 4.0~6.0 |
Mechanical performance testing was performed according to ISO 14801:2016. For compatible OEM implant lines, worst-case constructs were subjected to static compression fatigue testing. The fatigue limit data for all other implant lines demonstrated the construct strengths to be sufficient for their intended use.
## Non-clinical Testing
The subject device was tested to evaluate its substantial equivalence according to the following standards.
- Fatigue Test according to ISO 14801:2016
Below tests were performed for predicate device (K201197) and leveraged for the subject device:
- 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 predicate device. The results of the above tests have met the criteria of the standard, and demonstrated the substantial equivalence with the predicate device.
Comparative fatigue testing of the subject and predicate devices was conducted in accordance with ISO 14801 and 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 worst-case scenario, (smallest diameter with maximum angulation) through fatigue testing.
Dimensional analysis and reverse engineering of the implant-to-abutment connection platform were performed, including an assessment of maximum and minimum dimensions of critical design aspects, tolerances, and cross-sectional images of the submission device and compatible OEM implant body, OEM abutment, and OEM fixation screw. The testing demonstrated implant to abutment compatibility and has established substantial equivalency of the proposed device with predicate devices.
Clinical testing was not necessary to establish substantial equivalency of the device.
## Conclusion
The TruBase S 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 device. Therefore, TruBase S and its predicate are substantially equivalent.
