Dear Melissa Burbage:

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 (the 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. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

# SUBJECT DEVICE DESCRIPTION

The purpose of this submission is to expand the DESS Dental Smart Solutions abutment system cleared under K221301 and K240982 to allow additional options of zirconia material, scanners, CAM software, and milling machines to the digital dentistry workflow. The subject devices are to be sent to Terrats Medical validated milling centers for manufacture, or to be designed and manufactured via a digital dentistry workflow. The digital dentistry workflow integrates multiple components: scan files from intra-oral and lab (desktop) scanners, CAD software, CAM software, titanium and ceramic material, milling machine, and associated tooling and accessories. There are no changes to the abutment design, implant compatibilities, or design parameters. All part numbers have been cleared for manufacturing via a validated milling center and digital dentistry workflows (also referred to as point of care) under K221301 and K240982.

The subject device DESS Dental Smart Solutions abutments provide a range of prosthetic solutions for dental implant restoration. DESS abutments are offered in a variety of connection types to enable compatibility with currently marketed dental implants. All abutments are provided non-sterile, and each abutment is supplied with the appropriate abutment screw (if applicable) for attachment to the corresponding implant.

Subject device Base Abutments are designed for fabrication of a patient-specific CAD/CAM zirconia superstructure on which a crown may be placed. They are two-piece abutments for which the second part (or top half) is the ceramic superstructure. They also may be used for support of a crown directly on the abutment.

All patient-specific custom abutment fabrication for Base Abutments and Pre-milled (Blank) Abutments is by prescription on the order of the clinician. The subject device Pre-milled (Blank) Abutments and all zirconia superstructures for use with the subject device Ti Base Interface, DESS Aurum Base, ELLIPTIBase, and DESS C-Base will be manufactured using a validated milling center or a digital dentistry workflow. A validated milling center will be under FDA quality system regulations. The digital dentistry workflow scans files from intra-oral and lab (desktop) scanners, CAD software, CAM software, titanium and ceramic material, milling machine and associated tooling and accessories.

The digital dentistry workflow uses scan files from intra-oral and lab (desktop) scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories. The digital workflow includes the following products:

## MATERIAL COMPOSITION

Zirconia is the material required for superstructures on Ti Base Interface, DESS Aurum Base and ELLIPTIBase, and C-Base with the base portion made of titanium alloy conforming to ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401). The cement required in labeling for bonding of superstructures to the base is Multilink Hybrid Abutment Cement from Ivoclar Vivadent AG, cleared under K130436. There have been no changes to the required cement material, processing, or handling, as cleared in K221301 and K240982.

Zirconia is the material required for superstructures. The zirconia materials have all been cleared by FDA and are conforming to ISO 6872 Dentistry – Ceramic Materials.

All subject device pre-milled blanks, base, and screws are made of titanium alloy conforming to ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401) or from Co-Cr-Mo alloy conforming to ASTM F1537 Standard Specification for Wrought Cobalt-28Chromium-6Molybdenum Alloys for Surgical Implants (UNS R31537, UNS R31538, and UNS R31539). There have been no changes in material, processing, or handling of the bases and screws. These products are treated with the same surface treatments (SelectGrip surface, anodization, and DLC coating) and are manufactured in the same or similar facilities using the same or similar manufacturing processes as used for the Terrats Medical components previously cleared in K221301 and K240982.

## PERFORMANCE DATA

Non-clinical data submitted to demonstrate substantial equivalence included the following: Sterilization validation according to ISO 17665-1, ISO 17665-2, and ISO 14937; biocompatibility testing according to ISO 10993-5 and ISO 10993-12; validation testing of the CAM restriction zones; fatigue testing and reverse engineering analysis of OEM implant bodies, OEM abutments, and OEM abutment screws to confirm compatibility were leveraged from K221301 and K240982; MR Conditional labeling; and validation testing of the CAD design restrictions were leveraged from K221301 and K240982. Fatigue testing of OEM implant bodies with patient specific abutments made at worst case angled conditions. Software verification included testing of restrictions that prevent design of components outside of the stated design parameters. In addition, the abutment design library was validated to demonstrate that the established design limitations and specifications are locked and cannot be modified by the user. To address the potential risk of damage to the implant-abutment connection geometry during the milling of the patient-matched portions of the abutment blanks, validation testing of the CAM restriction zones was conducted, including verification to show avoidance of damage or modifications of the connection geometry, and locking of restriction zones from user editing in the CAM software. No clinical data were included in this submission.

## EQUIVALENCE TO MARKETED DEVICES

Subject device abutments are identical to the predicate device K221301 and K240982. Both are intended for use with endosseous dental implants to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible. Both have the same compatible OEM implants. Both indicate manufacturing using a validated milling center or to be designed and manufactured using a digital dentistry workflow. The digital dentistry workflow integrates multiple components: scan files from intra-oral and lab (desktop) scanners, CAD software, CAM software, ceramic material, milling machine, and associated tooling and accessories.

All subject device abutments (base and blanks) and screws are equivalent in design, materials and technological characteristics to those of the predicate device K221301 and K240982. There are no changes to the abutment designs or implant compatibilities. The material of the abutment and superstructure is equivalent to the predicate device K221301 and K240982. All part numbers and design parameters have been cleared within previous submissions cleared for manufacturing via a validated milling center and digital dentistry workflow.

## CONCLUSION

The subject device, the predicate device, and reference devices have the same intended use, technological characteristics, and are made of the same materials. The subject device, the predicate device, and reference devices encompass the same range of physical dimensions, manufactured by similar methods, are packaged in similar materials, and are to be sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
