## Dear Calvin Shim:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

Substantial Equivalence discussion differences: The only difference between the subject device and the reference predicate is the maximum angulation. Solidex Customized abutments have a less extreme maximum angulation. The difference is also mitigated by fatigue testing and reverse engineering dimensional analysis.

| Compatible Device | Implant Diameters | Implant Lengths |

| Straumann Tissue Level<br>Standard Plus | RN 3.3mm | 6 mm<br>8 mm<br>10 mm<br>12 mm<br>14 mm |
| | WN 6.5mm | 6 mm<br>8 mm<br>10 mm<br>12 mm |

### The CreoDent Solidex® Customized Abutment is compatible with the following:

Non-clinical Testing Data: Static/Fatigue testing was conducted in accordance with ISO 14801:2007E Dentistry-Implants-Dynamic fatigue test for endosseous dental implants with the worst case scenario for the Solidex® Customized Abutment and Screw connection platform. Reverse engineering dimensional analysis was conducted using OEM implant bodies, OEM abutments and OEM abutment screws. Sterilization was conducted according to ISO 17665-1 was performed. These results demonstrated that the Solidex® Customized Abutment and Screw have sufficient mechanical strength for their intended clinical application and are compatible with Straumann Tissue Level Standard Plus RN 3.3 and WN 6.5 for which they are intended. Biocompatibility information is leveraged from our previous 510k (K150012).

# CONCLUSION:

Solidex Customized Abutments incorporates the same material, similar indications for use, dimension, design, abutment seat, screw seat, anatomical site, connection, type of retention and technological characteristics as the predicate device (K150012). Both the subject and predicate device share intended use. The only significant difference between the devices is the implant platform compatibility which has been mitigated through dynamic fatigue testing and 3rd party compatibility testing. The Solidex Customized abutments are substantially equivalent to the predicate (K150012).
