# SUBJECT DEVICE DESCRIPTION

The purpose of this submission is to expand the DESS Dental Smart Solutions abutment system cleared under K22288 to add the ability for the subject device Base Abutments and Pre-milled (Blank) Abutments to be manufactured via a digital dentistry workflow by using scan files from intra-oral and lab (desktop) scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories. There are no changes to the abutment design or implant compatibilities, however, there is a new material for the zircomia superstructure. All part numbers have been cleared within previous submissions for manufacturing at a validated milling center. The purpose of this submission is to allow manufacturing via digital dentistry workflow and to add a new zirconia material for the superstructures of the two-piece abutment.

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 digital dentistry workflow by using scan files from intra-oral and lab (desktop) scanners, CAD software, 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 (not subject devices of this submission):

- . Ceramic material: VITA YZ ST and VITA YZ XT (K180703)
- Cement: Ivoclar Vivadent Multilink Hybrid Abutment Cement (K130436)

- Desktop scanner: 3Shape D900 Dental Lab Scanner (510(k) exempt under 21 CFR 872.3661)
- Abutment design software: 3Shape Abutment Designer Software (K151455)
- . Milling machine: VHF R5 by vhf camfacture AG with DentalCAM and DentalCNC 7 software

The design parameters for the CAD/CAM zirconia superstructure to be used on Base Abutments: Minimum wall thickness – 0.4 mm Minimum post height for single-unit loading Ti Base Interface - 4.2 mm DESS Aurum Base – 4.0 mm ELLIPTIBase - 4.0 mm C-Base - 4.7 mm CoCr Base - 4.5 mm Minimum gingival height - 0.5 mm Maximum gingival height – 6.0 mm

All zirconia superstructures are for straight abutments only.

{7}------------------------------------------------

The design parameters for the CAD/CAM Pre-Milled Blank custom abutments: Minimum wall thickness - 0.4 mm Minimum post height - 4.0 mm Maximum gingival height - 6.0 mm Minimum gingival height - 0.3 mm All Pre-Milled Blank are for straight abutments only.

For the CAD/CAM Pre-milled Blanks that are compatible with Astra Tech EV (except for 3.0 mm implants), Astra Tech OsseoSpeed, Biomet 3i Certain, Nobel Active/NobelParallel Conical (except for 3.0 mm implants), NobelReplace Trilobe. Nobel Brånemark, Straumann Bone Level, and Zimmer Screw-Vent/Tapered Screw-Vent, the following design parameters may be used:

Minimum wall thickness - 0.45 mm Minimum post height - 4.0 mm Maximum gingival height - 6.0 mm Minimum gingival height - 0.3 mm Maximum angulation of the final abutment - 30°

# Screws

The new material recommended for zirconia superstructures on Ti Base Interface, DESS Aurum Base and ELLIPTIBase, C-Base, and CoCr Base is VITA YZ ST and VITA YZ XT, conforming to ISO 6872 Dentistry - Ceramic Materials and cleared in K180703. This material is equivalent to those cleared in K22288.

The cement recommended in labeling for bonding of superstructures is Multilink Hybrid Abutment Cement from Ivoclar Vivadent AG, cleared under K130436. This material is the same as that used for devices cleared in K222288.

All subject device components are manufactured from the same or similar materials, are treated with the same surface treatments (SelectGrip® surface, DLC coating and anodization), and are manufactured in the same or similar facilities using the same manufacturing processes cleared in K170588, K173908, K191986, K203464, K212577, and K212628. The facilities may be different in that the CAD/CAM portion of the abutment may be manufactured in dental laboratories; however, the equipment and procedures are intended to be the same as those used by the validated milling centers.

# 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 for titanium; fatigue testing and reverse engineering analysis of OEM implant bodies, OEM abutments, and OEM abutment screws to confirm compatibility; and MR Conditional labeling were leveraged from K222288. Biocompatibility testing according to ISO 10993-5 and ISO 10993-12 was included for the new zirconia material used for zirconia superstructures, tested alone and cemented to Ti Base abutments and for patient-specific abutments fabricated from Pre-milled Blanks using the new manufacturing (point of care) process. 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 substantially equivalent in intended use to the primary predicate device K222288 and reference devices K201860, K180703, K130436, and K151455. All are intended for use with endosseous dental implants to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible. The Indications for Use Statement (IFUS) for the subject device is substantially equivalent to that of the primary predicate device K222288 for compatible OEM implants and manufacturing using a validated milling center.

{10}------------------------------------------------

The Indications for Use Statement (IFUS) for the subject device is substantially equivalent to that of the reference device K201860 for manufacturing 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. The differences between the subject device IFUS and primary predicate device K222288 do not raise different questions of substantial equivalence, as demonstrated by manufacturing software validation and workflow validation.

All subject device abutments (base and blanks) and screws are equivalent in design, materials and technological characteristics to those of the primary predicate device K222288. There are no changes to the abutment designs or implant compatibilities. However, there is a new Y-TZP material for the zirconia superstructure. All part numbers have been cleared within previous submissions for manufacturing via a validated milling center. The purpose of this submission is to allow manufacturing via digital dentistry workflow.

# CONCLUSION

The subject device, the primary predicate device, the additional predicate devices, and reference device have the same intended use, have similar technological characteristics, and are made of the same or similar materials. The subject device, the primary 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.
