Intended Use

The SFI-Bar® is intended to be used with the implant manufacturer's (Table 1) implant to provide support for fixation of overdentures.

Device Story

SFI-Bar® is a dental abutment system providing connection between endosseous dental implants and removable overdentures. Device consists of an implant adapter (abutment) and a stress-free bar. Adapter is screwed into compatible dental implants (Thommen, Neoss, Straumann); bar provides retentive system for overdenture fixation. Used in clinical settings by dental professionals. Functions to stabilize overdentures, distribute shear forces, and compensate for resilience. Benefits include secure denture fixation and primary splinting of implants. Non-sterile, supplied in dental blisters.

Clinical Evidence

Bench testing only. No clinical data. Testing included torque tests, application testing, and functional testing to evaluate performance characteristics across compatible implant platforms. Acceptance criteria were met, demonstrating performance equivalent to the predicate device.

### Summary Technological Characteristics:

Comparison /Compatibility Substantially Equivalence: The proposed implant adapters are substantially equivalent to the currently marketed predicate devices. The intended use, basic design, fundamental operating principles and manufacturing procedures are the same as the predicate device.

The material of the implant adapters conform to ASTM F 136, Wrought Titanium-6Aluminium-4Vanadium ELI Alloy for Surgical Implant applications (UNS R 56401). The parts for the SFI-Bar® System are manufactured from wires.

The proposed implant adapters are substantially equivalent to the currently marketed predicate devices. The intended use, basic design, fundamental operating principles and manufacturing procedures are the same as the predicate device.

To ensure compatibility the following process was carried out: The implant adapters are developed.and manufactured in close cooperation with the implant companies (see Table 1 , column "Implant Company").

There are Quality Agreements between Cendres + Métaux and the implant companies in place. Those agreements handle among other things the Design Control, Change Control, Complaint Handling and Post Market Surveillance.

Table 2 summarizes the substantial equivalence comparison to the predicate device:

Performance Data:

Summary of Testing to Demonstrate Safety and Effectiveness / Conclusion:

Torque tests, application testing and functional testing have been conducted to evaluate the performance characteristics of the additional SFI-Bar®. The test methods used were the same as in the predicate device. Testing has shown that the SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar®. The acceptance criteria were met.

Non-clinical test data was used to support the substantially equivalence claim. Clinical testing was not necessary. Non-clinical testing consisted of analysis of platforms to identify worst-case test samples. Fatigue testing was not done as the basic design is the same than the predicate device. The evaluation was based on FDA guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments." Torque tests, application and functional tests have been carried out.

The summary of technological characteristics as well as the torque test, application and functional testing indicate that the device is safe and effective for its intended use and performs as well or better than the predicate devices.
