More Information

No
The summary describes physical dental abutments and their compatibility with various implant systems. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.

Yes.

The device is intended to be used with dental implants to provide support for prosthetic restorations, which is a therapeutic function for patients requiring dental prostheses.

No

Explanation: The device, DESS Dental Smart Solutions abutments, is intended to provide support for prosthetic restorations in conjunction with dental implants. Its use is related to treatment and support, not the identification or diagnosis of a condition.

No

The device description explicitly states that the submission includes physical abutments made of titanium alloy, Co-Cr-Mo alloy, and zirconia. It also mentions that the abutments are provided non-sterile and each is supplied with an appropriate abutment screw. This indicates the device is a physical medical device, not software-only.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the abutments are used "in conjunction with endosseous dental implants... to provide support for prosthetic restorations." This describes a device used in vivo (within the body) for structural support, not a device used in vitro (outside the body) to examine specimens from the human body for diagnostic purposes.
  • Device Description: The description focuses on the physical components, materials, and compatibility with dental implants. There is no mention of analyzing biological samples or providing diagnostic information.
  • Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing blood, urine, tissue, or other biological specimens.
    • Detecting or measuring specific substances (analytes).
    • Providing information for the diagnosis, monitoring, or treatment of a disease or condition based on the analysis of biological samples.

The device described is a dental prosthetic component, not a diagnostic tool.

Device Description

The purpose of this submission is to expand the DESS Dental Smart Solutions abutment system cleared under K170588 and K173908 to add additional components for previously cleared OEM platform compatibilities and to add additional OEM platform compatibilities for previously cleared DESS abutment designs. In total, this submission includes abutments compatible with 43 implant platforms from 16 OEM implant systems. Note that, because Nobel Active and NobelParallel Conical Connection implants share conical connection platforms, we have shown them as one system for purposes of this submission.
This submission includes abutments compatible with five (5) additional OEM implant systems (11 platforms) and abutments compatible with six (6) additional platforms for OEM implant system compatibilities that were cleared in K170588.
Additional subject device components for previously cleared compatibilities include addition of gingival heights of 1.5 mm and 3.0 mm for titanium bases and addition of 17° and 30° angled multi-unit abutments to the previously cleared straight multi-unit abutments.
Abutment designs and the correlation between each subject device abutment design and the corresponding compatible implant platforms are shown in Table 1 Summary of DESS Components and Abutment Platforms for Compatible Implant Systems.
All abutments are provided non-sterile and each abutment is supplied with the appropriate abutment screw (if applicable) for attachment to the corresponding implant.
All subject device abutments are made of titanium alloy conforming to ASTM F136, Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401) or 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). All ceramic components of the Ti Base abutments are composed of zirconia conforming to ISO 13356 Implants for surgery - Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP).

Ti Base (Interface) is a two-piece abutment designed for custom abutment fabrication with a CAD/CAM zirconia superstructure on which a crown may be placed. The ceramic superstructure produced through CAD/CAM is the second part of the two-piece abutment. The Ti Base may also support a ceramic Hybrid abutment in which the crown is included in the design of the abutment ceramic superstructure. The prosthetic post height is 4.2 mm. It is available in an engaging design and a non-engaging design. TiBase (Interface) is made of titanium allov (Ti-6A1-4V) with a Select(Grip® surface. When used for a direct crown, TiBase (Interface) may be used with a POM burn out sleeve, which is available for laboratory fabrication of the prosthesis.
Designs of Ti Base (Interface) that are the subject of this submission are identical, including the SelectGrip surface, to those cleared under K170588, but are provided in gingival heights of 1.5 mm and 3.0 mm for implant connections cleared in K170588 and are provided for three (3) additional implant compatibilities (four systems) and additional platforms for systems cleared in K170855.
The design parameters for the CAD/CAM zirconia superstructure to be used on Ti Base (Interface) are identical to those cleared in K170588. They are:
Minimum wall thickness – 0.4 mm Minimum post height - 4.2 mm Maximum gingival height - 6.0 mm All zirconia superstructures are for straight abutments only.

Ti Base (DESS Aurum) is a two-piece abutment used as a base that can be used for a direct multi-unit restoration or to support a CAD/CAM zirconia superstructure plus a single-unit or multi-unit restoration. The ceramic superstructure produced through CAD/CAM is the second part of the two-piece abutment. It is available in an engaging design and a non-engaging design. Before attachment of the zirconia superstructure or crown, the Ti Base (DESS Aurum) post height is 3.0 mm. When used for a single-unit restoration the Ti Base (DESS Aurum) is to be used with a superstructure to create a minimum post height of 4 mm. Ti Base (Aurum) is made of titanium alloy (Ti-6A1-4V) with a gold anodized surface. Abutments are colored gold by an anodization process in which the abutment is submerged in an electrolytic solution and exposed to an electric current to achieve the gold color.
Design of Ti Base (DESS Aurum), including the titanium alloy and the anodization treatment, is identical to that cleared as DESS Aurum Abutment in K173908, except that the subject device is provided in four additional implant system compatibilities as shown in Table 11.12 Ti Base (DESS Aurum), Engaging and Non-engaging.
When the Ti Base (DESS Aurum) is used with a zirconia superstructure, design parameters for the zirconia superstructure are identical to those cleared in K173908. They are:
Minimum wall thickness - 0.4 mm
Minimum post height for single-unit restorations – 4.0 mm
Maximum gingival height - 6.0 mm
All zirconia superstructures are for straight abutments only.
All patient-specific custom abutment fabrication for TiBase (Interface) and Ti Base (DESS Aurum is by prescription on the order of the clinician. All zirconia superstructures for use with the subject device Ti Base (Interface) and Ti Base (Aurum) will be made at a Terrats Medical validated milling center under FDA quality system regulations, and the material will conform to ISO 13356 Implants for surgery -Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP).
DESS Dental Smart Solutions screws are designed to attach the abutment to the implant or the prosthesis to the abutment. Abutment screws for the DESS Abutment Systems Tri-Lobe and External Hex Universal, and prosthetic screws for Multi-unit Abutments are available with the DLC (Diamond-like Carbon) coating to provide a low friction surface finish, designed to improve the preload of the screw and to produce a high clamping force between the abutment and the implant. This allows the clinician to apply less torque while achieving the same clamping force with the screw. DLC coating is a polycrystalline tungsten carbide/carbon and chromium coating that is identical to the DLC coating on screws cleared in K170588.

SUBJECT DEVICE DESCRIPTION

The purpose of this submission is to expand the DESS Dental Smart Solutions abutment system cleared under K170588 and K173908 to add additional components for previously cleared OEM platform compatibilities and to add additional OEM platform compatibilities for previously cleared DESS abutment designs. In total, this submission includes abutments compatible with 43 implant platforms from 16 OEM implant systems. Note that, because Nobel Active and NobelParallel Conical Connection implants share conical connection platforms, we have shown them as one system for purposes of this submission.

This submission includes abutments compatible with five (5) additional OEM implant systems (11 platforms) and abutments compatible with six (6) additional platforms for OEM implant system compatibilities that were cleared in K170588.

Additional subject device components for previously cleared compatibilities include addition of gingival heights of 1.5 mm and 3.0 mm for titanium bases and addition of 17° and 30° angled multi-unit abutments to the previously cleared straight multi-unit abutments.

Abutment designs and the correlation between each subject device abutment design and the corresponding compatible implant platforms are shown in Table 1 Summary of DESS Components and Abutment Platforms for Compatible Implant Systems.

All abutments are provided non-sterile and each abutment is supplied with the appropriate abutment screw (if applicable) for attachment to the corresponding implant.

All subject device abutments are made of titanium alloy conforming to ASTM F136, Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401) or 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). All ceramic components of the Ti Base abutments are composed of zirconia conforming to ISO 13356 Implants for surgery - Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP).

Ti Base (Interface) is a two-piece abutment designed for custom abutment fabrication with a CAD/CAM zirconia superstructure on which a crown may be placed. The ceramic superstructure produced through CAD/CAM is the second part of the two-piece abutment. The Ti Base may also support a ceramic Hybrid abutment in which the crown is included in the design of the abutment ceramic superstructure. The prosthetic post height is 4.2 mm. It is available in an engaging design and a non-engaging design. TiBase (Interface) is made of titanium allov (Ti-6A1-4V) with a Select(Grip® surface. When used for a direct crown, TiBase (Interface) may be used with a POM burn out sleeve, which is available for laboratory fabrication of the prosthesis.

Designs of Ti Base (Interface) that are the subject of this submission are identical, including the SelectGrip surface, to those cleared under K170588, but are provided in gingival heights of 1.5 mm and 3.0 mm for implant connections cleared in K170588 and are provided for three (3) additional implant compatibilities (four systems) and additional platforms for systems cleared in K170855.

The design parameters for the CAD/CAM zirconia superstructure to be used on Ti Base (Interface) are identical to those cleared in K170588. They are:

Minimum wall thickness – 0.4 mm Minimum post height - 4.2 mm Maximum gingival height - 6.0 mm All zirconia superstructures are for straight abutments only.

Ti Base (DESS Aurum) is a two-piece abutment used as a base that can be used for a direct multi-unit restoration or to support a CAD/CAM zirconia superstructure plus a single-unit or multi-unit restoration. The ceramic superstructure produced through CAD/CAM is the second part of the two-piece abutment. It is available in an engaging design and a non-engaging design. Before attachment of the zirconia superstructure or crown, the Ti Base (DESS Aurum) post height is 3.0 mm. When used for a single-unit restoration the Ti Base (DESS Aurum) is to be used with a superstructure to create a minimum post height of 4 mm. Ti Base (Aurum) is made of titanium alloy (Ti-6A1-4V) with a gold anodized surface. Abutments are colored gold by an anodization process in which the abutment is submerged in an electrolytic solution and exposed to an electric current to achieve the gold color.

Design of Ti Base (DESS Aurum), including the titanium alloy and the anodization treatment, is identical to that cleared as DESS Aurum Abutment in K173908, except that the subject device is provided in four additional implant system compatibilities as shown in Table 11.12 Ti Base (DESS Aurum), Engaging and Non-engaging.

When the Ti Base (DESS Aurum) is used with a zirconia superstructure, design parameters for the zirconia superstructure are identical to those cleared in K173908. They are:

Minimum wall thickness - 0.4 mm

Minimum post height for single-unit restorations – 4.0 mm

Maximum gingival height - 6.0 mm

All zirconia superstructures are for straight abutments only.

All patient-specific custom abutment fabrication for TiBase (Interface) and Ti Base (DESS Aurum is by prescription on the order of the clinician. All zirconia superstructures for use with the subject device Ti Base (Interface) and Ti Base (Aurum) will be made at a Terrats Medical validated milling center under FDA quality system regulations, and the material will conform to ISO 13356 Implants for surgery -Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP).

DESS Dental Smart Solutions screws are designed to attach the abutment to the implant or the prosthesis to the abutment. Abutment screws for the DESS Abutment Systems Tri-Lobe and External Hex Universal, and prosthetic screws for Multi-unit Abutments are available with the DLC (Diamond-like

10

Carbon) coating to provide a low friction surface finish, designed to improve the preload of the screw and to produce a high clamping force between the abutment and the implant. This allows the clinician to apply less torque while achieving the same clamping force with the screw. DLC coating is a polycrystalline tungsten carbide/carbon and chromium coating that is identical to the DLC coating on screws cleared in K170588.

PERFORMANCE DATA

Non-clinical data submitted to demonstrate substantial equivalence included: sterilization validation according to ISO 17665-1 and ISO 14937; biocompatibility according to ISO 10993-12; reverse engineering analysis of OEM implant bodies, OEM abutment, and OEM abutment screws to confirm compatibility; and static compression and compression fatigue testing according to ISO 14801. No clinical data were included in this submission.

EQUIVALENCE TO MARKETED DEVICES

The subject device is substantially equivalent in indications and design principles to the primary predicate device and the reference devices listed above. Provided at this summary are tables comparing the Indications for Use Statements and the technological characteristics of the subject device, the primary predicate device, and the reference devices.

Subject device abutments are substantially equivalent in intended use to the primary predicate device cleared in K170588 and the reference devices cleared in K173908 and K161416. 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. The Indications for Use Statement (IFUS) for the subject device is substantially equivalent to that of the primary predicate K170588, except for the list of compatible OEM implants.

All subject device abutments are identical in design, materials and technological characteristics to those of the primary predicate K170588, with the exception of Multi-unit Abutments Angled, Ti Base (Interface) with gingival heights 1.5 mm and 3.0 mm and Ti Base (DESS Aurum). Subject device Multiunit Abutments Angled are substantially equivalent in design, materials and technological characteristics to Multi-Unit Abutment Plus, cleared in reference device K161416. Abutments with gingival heights of 1.5 mm, 3.0 mm and greater are in common use in dental implant systems such as compatible system Astra Tech EV, cleared in K111287. Subject device Ti Base (DESS Aurum) is identical in design, materials and technological characteristics to Aurum Abutments cleared in reference device K173908. The SelectGrip® surface on Temporary Abutments. Straight Abutments and Ti Base (Interface) is identical to the SelectGrip surface on equivalent abutments cleared in primary predicate K170588. The gold anodized surface on Ti Base (DESS Aurum) is identical to the anodized surface on Aurum Abutments of the reference device K173908. The ZrN coating on DESSLoc is identical to that on DESS LOC Abutments cleared in primary predicate K170588.

All screws are identical in design, materials and technological characteristics to those cleared in primary predicate K170588 except for threads that accommodate the new compatibilities. Diamond-like carbon (DLC) coatings on screws are identical to those on screws cleared in primary predicate K170588.

Substantial equivalence of new compatibilities is supported by compatibility analysis.

Substantial equivalence of Multi-unit Abutments Angled is supported by dynamic testing according to ISO 14801 Dentistry - Implants - Dynamic fatigue test for endosseous dental implants.

Digital files for all CAD/CAM superstructures or abutments from blanks must be sent to a validated milling center for manufacture. DESS Ti Base (Interface), Ti Base (DESS Aurum), CrCo Base, and Premilled Blank abutments are for fabrication of straight custom abutments only.

The subject device is to be sterilized by the end-user, the same as primary predicate device K170588 and reference device K173908.

All of the subject device components are manufactured from the same materials and in the same facilities using the same manufacturing processes as used for the Terrats Medical components previously cleared in K170588 and K173908. Therefore, no new biocompatibility testing has been performed, as the subject device is substantially equivalent to the predicate devices in K170588 and K173908 with regards to materials and processing.

Minor differences in the designs, dimensions, sizes, or compatible OEM implant lines among the subject device, the primary predicate device, and the reference devices do not affect substantial equivalence. These minor differences do not impact substantial equivalence because these differences are related to the compatible OEM implant designs or are mitigated by the mechanical performance testing.

CONCLUSION

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