Clinical performance data is not required to establish substantial equivalence for the subject devices.
## EQUIVALENCE TO MARKETED DEVICES
The subject device abutments are substantially equivalent in intended use to the primary predicate device K161416, and the reference devices K192614 and K240208. 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.
{8}------------------------------------------------
The primary predicate device K161416 and the reference devices K192614 and K240208 are in support of the substantial equivalence of the subject device designs, material, manufacturing, and biocompatibility.
All subject device abutments have identical materials as the predicate device is different in technology compared to the predicate, as it has a variable angulation and differently designed components. The device has many common characteristics with the predicate and reference devices as found in 510(k)sK161416, K192614, and K240208. The subject submission, K161416, K192614, and K240208 all include abutments manufactured from Ti-6Al-4V alloy conforming to ASTM F136. The scientific data described above demonstrates that the subject device has equivalent performance compared to the predicate device.
The subject device abutments have similar or identical ranges of abutment-implant platform diameter, prosthetic platform diameter, and angulation as the components cleared in K161416, K192614, and K240208.
The subject device abutments and the reference device K240208 include abutments compatible with the Reference Devices for OEM Implant Body Clearances above.
The subject device abutments and the reference device K240208 include non-sterile provided devices.
The risks associated with the use of the subject device abutment angulation with the compatible implants are mitigated by the mechanical testing as described in the performance testion of this summary.
## CONCLUSION
Any differences in the technological characteristics between the subject device, the predicate device, and reference devices do not raise different questions of safety or effectiveness. The data included in this submission demonstrate substantial equivalence to the predicate and reference devices listed above.
Overall, the subject devices have the following similarities to the primary predicate and reference devices:
- Have similar intended use,
- Use similar operating principles,
- Incorporate identical materials,
- Are sterilized using similar materials and processes,
- And have similar packaging
The basis for the belief of Smart Denture Conversions, LLC that the subject device is substantially equivalent to the predicate devices is summarized in the following Table 3, Substantial Equivalence.
