## Subject Device Designs

**Healing Abutments** are provided in gingival heights from 3 mm to 5 mm to aid in contouring the gingiva during healing. Healing Abutments are made of PEEK.

**Temporary Abutments** are provided for multiple-unit restorations, the former with engaging connections to the implants and the latter with non-engaging connections. All Temporary Abutments have a gingival height from 1.5 mm and are made of PEEK, and with a prosthetic platform diameter of 4.5 mm to 6.0 mm.

**Ti Base Abutments** are provided in engaging and non-engaging designs for custom abutment fabrication of a CAD-CAM zirconia superstructure on which a crown may be placed. They also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure.. The two-pieces of the Ti Base Abutment which compose the final abutment consists of the pre-manufactured titanium base component composed of titanium alloy and the CAD-CAM patient matched superstructure or hybrid abutment crown composed of zirconia. The cement required for bonding of superstructures is Multi-Link cement by Ivoclar Vivadent (K130436). Ti Base Abutments are manufactured from titanium alloy (Ti-6Al-4V) with the SelectGrip® surface.

Ti Base Abutments also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure. When used for a direct crown, Ti Base abutments may be used with POM burn out sleeve, an exempt laboratory component not a subject of this submission, that is available for laboratory fabrication of the prosthesis. Ti Bases are not intended for angulation correction when used with a POM burn-out sleeve.

**AURUM Base Abutments** are provided in engaging and non-engaging designs. The two-pieces of the AURUM Base Abutment which compose the final abutment consists of the pre-manufactured titanium base component composed of titanium alloy and the CAD-CAM patient matched superstructure

composed of zirconia. The design of the AURUM Base Abutment allows for easier instrument access to the abutment screw and allows for placement of the screw channel out of the esthetic region of the restoration. AURUM Base Abutments are provided with a prosthetic platform diameter of 5.5 mm, with gingival heights (in the base) of 1 mm.

AURUM Base Abutments are manufactured from titanium alloy (Ti-6Al-4V) and anodized a gold color, and the SelectGrip® surface to aid in bonding retention. The design of the AURUM Base Abutments, including the titanium alloy, anodization treatment, and SelectGrip® surface is similar to that of DESS AURUM Base Abutments cleared in K240208.

**C-Base Abutments** are provided in engaging and non-engaging designs. C-Base Abutments are two-piece abutments designed to support a custom CAD-CAM zirconia superstructure on which a single-unit or multi-unit restoration may be placed. The ceramic superstructure produced through CAD-CAM is the second part of the two-piece abutment. The C-Base Abutment also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure.

The C-Base Abutment prosthetic post is 4.68 mm, and the gingival height is 1 mm to 3 mm. All patient-specific custom abutment fabrication is by prescription on the order of the clinician. C-Base Abutments are made of titanium alloy (Ti-6Al-4V) with anodization and a SelectGrip® surface.

C-Base Abutments also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure. When used for a direct crown, C-Base abutments may be used with POMburn out sleeve an exempt laboratory component not a subject of this submission, that is available for laboratory fabrication of the prosthesis. C-Bases are not intended for angulation correction when used with a POM burn-out sleeve.

**ELLIPTIBase Abutments** are available in an engaging design. ELLIPTIBase Abutments are two-piece abutments designed to support a custom CAD-CAM zirconia superstructure on which a single-unit or multi-unit restoration may be placed. The ceramic superstructure produced through CAD-CAM is the second part of the two-piece abutment. The ELLIPTIBase Abutment also may support a ceramic hybrid abutment in which the crown is included in the design of the zirconia abutment ceramic superstructure.

Before attachment of the zirconia superstructure or crown, the ELLIPTIBase post height is 3.0 mm. When used for a single-unit restoration the ELLIPTIBase is to be used with a superstructure to create a minimum post height of 4.0 mm. ELLIPTIBase is made of titanium alloy (Ti-6Al-4V ELI) with a gold anodized surface

The design parameters for the CAD/CAM zirconia superstructures are summarized in Table 1 and Figure 1 below.

All subject device abutments are similar or identical in design, materials and technological characteristics to corresponding abutments of the primary predicate device K170588 and the additional predicate devices K222269, K240208, and K120954.

The design of the Temporary and Healing abutment is the same as predicate devices K170588 and K222269. The PEEK material is the same as additional predicate device K120954.

The design of the Base Abutments (Ti Base, AURUM, C-Base, ELLIPTIBase models) is the same as predicate devices K170588 (abutment design) and K240208 (angulation and OEM connection).

The SelectGrip® surface on the subject device Ti Base Abutments is identical to the Select Grip® surface on equivalent abutments cleared in K170588, K222269, and K240208. The gold anodized surface on the subject device AURUM Base Abutments is identical to the anodized surface on Aurum Abutments of the predicate devices K170588, K222269, and K240208.

The cement required in labeling for bonding of superstructures is Multi-Link cement from Ivoclar Vivadent, cleared under K130436. This is the same cement required in labeling for the predicate devices K170588, K222269, and K240208.

All screws are identical in design, materials, and technological characteristics to those cleared in predicate devices K170588, K222269, and K240208, except for threads and lengths that accommodate the new compatibilities. The Diamond-like carbon (DLC) coating and Anodized applied to all screws is identical to anodizing or DLC surface on screws cleared in predicate device K252384, K240208 and K222269.

The design, including angulation, of the Multi-Unit Abutment is the same as the predicate K222269 with the exception of gold anodization. The gold anodized surface on the subject device Multi-Unit Abutment is identical to the anodized surface on Aurum Abutments of the predicate devices K170588 and K222269.

The risks associated with use of angulated abutments in combination with the compatible implants are mitigated by the mechanical testing.

The subject device is provided non-sterile to the end user for the end user to sterilize prior to use, the same as the primary predicate. The sterilization validation was conducted for the PEEK abutment.

## CONCLUSION

The subject device, the primary predicate device, and the additional predicate devices have the same intended use, have similar technological characteristics, and are made of the same materials. The subject device, the primary predicate, and additional predicate devices encompass the same range of physical dimensions, 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.
