Device Story

Sherlock is a dental implant abutment system providing support for single or multi-unit prosthetic restorations. The system includes Titanium Base, Titanium Blank, and Multi-Unit Abutments (straight, 17°, 30°). Inputs consist of patient-specific anatomical data used for CAD/CAM design of zirconia mesostructures or customization of titanium blanks. The device transforms these inputs into patient-matched abutments manufactured at validated milling centers. Used in dental clinics by clinicians; the output is a custom abutment bonded to the implant, facilitating prosthetic restoration. Benefits include improved functional and esthetic rehabilitation for edentulous patients. The system utilizes a two-piece design (titanium base and zirconia superstructure) or one-piece titanium blank. The workflow involves clinician prescription, digital design, and milling. The final assembly is secured to the implant via a screw. The device is provided non-sterile and requires end-user steam sterilization.

Clinical Evidence

No clinical or animal testing data included. Substantial equivalence is supported by non-clinical bench testing, including static and fatigue testing per ISO 14801 on worst-case constructs, reverse engineering of OEM implant interfaces, and leveraging of biocompatibility (ISO 10993-5), cleaning (AAMI TIR30), and sterilization (ISO 17665-1/14937) data from predicate/reference devices. MRI safety was evaluated via scientific rationale and literature review.

Technological Characteristics

Materials: Ti-6Al-4V ELI (Grade 23) titanium (ASTM F136) and yttria-stabilized tetragonal zirconia (ISO 13356). Design: Internal implant connection (engaging/non-engaging). Dimensions: 3.0mm platform diameter; 3.5-7.0mm implant body compatibility. Connectivity: CAD/CAM workflow for patient-specific customization. Sterilization: Non-sterile, end-user steam sterilization. Software: CAD/CAM design parameters (min wall thickness 0.5-0.75mm, max angle 30°).

Indications for Use

Indicated for patients requiring dental prosthetic restorations supported by endosseous dental implants in the maxillary or mandibular arch. Compatible with Neodent Helix GM, Drive GM, and Titamax GM implant systems (3.5-7.0mm body diameters, 3.0mm platform).

The Subject device Titanium Base abutments are intended to be used as a two-piece abutment composed of the base bottom-portion (prefabricated titanium base component) with a cemented/bonded CAD-CAM fabricated zirconia top-portion (superstructure) where the final two-piece abutment (base component and cemented superstructure) is the finished device used for the prosthetic restoration. Each patient-specific zirconia superstructure is individually prescribed by the clinician and manufactured by an authorized milling center.

All Subject device prefabricated titanium base components are provided in a straight design with no angulation in the titanium base post. They are provided with either an indexed/engaging implant connection for crowns or a non-engaging/nonindexed implant connections for bridges. The standard prefabricated titanium base components are provided in gingival heights ranging from 0.8 mm to 3.0 mm and abutment post lengths of 8 mm or 10 mm. The ASC prefabricated titanium base components are provided in gingival heights ranging 0.8 mm to 2.5 mm and abutment post length of 8 mm. Additional gingival height may be provided for both abutment designs in the zirconia superstructure. ASC prefabricated titanium base components are provided with a cutout in the prosthetic post to accommodate a restoration with an angled screw channel when clinically necessary. Standard prefabricated titanium base components and ASC prefabricated titanium base components posts may be reduced to 4 mm to accommodate individual patient occlusion. The zirconia mesostructure may contain an angled post within the established design parameters.

The overall design parameters for the two-part Standard and ASC CAD/CAM prefabricated titanium base components with zirconia mesostructure are:

- Minimum Zirconia Wall Thickness – 0.5 mm
- Minimum Post Height for single-unit abutment* – 4.0 mm
- Minimum Overall Gingival Height – 0.8 mm (titanium base plus zirconia)
- Maximum Overall Gingival Height – 5 mm
- Maximum Correction Angle – 30°

*measured above the gingival height of the final patient-matched mesostructure design

{6}

The required cement for bonding the zirconia superstructure to the Subject device Titanium Bases to create the final two-piece abutment is Kuraray Noritake Dental PANAVIA™ V5 cleared in K150704.

Titanium Blank abutments, sometimes referred to as “Pre-mill” or “Ti-Blank” abutments are one-part abutments intended for use in a CAD/CAM workflow. Each Subject device Titanium Blank implant abutment has a pre-manufactured indexed implant connection interface with a cylindrical customization section and a milling retention geometry section. The retention geometry holds the component in a milling machine fixture while the patient-specific portion above the implant interface is milled in a dental milling machine. All patient-specific Titanium Blank abutment fabrication is by prescription on the order of the clinician.

The overall design parameters for the Titanium Blank customized abutments are:

- Minimum Wall Thickness – 0.75 mm
- Minimum Post Height for single-unit abutment* – 4.0 mm
- Minimum Overall Gingival Height – 0.8 mm
- Maximum Overall Gingival Height – 5 mm
- Maximum Correction Angle – 30°

*measured above the gingival height of the final patient-matched design

All digitally designed zirconia mesostructures for use with the Subject device titanium base abutments and digitally designed Subject device titanium blank abutments will be fabricated at an Open Implants validated milling center under FDA quality system regulations.

Multi-Unit Abutments (MUAs) are intended for use with multi-unit restorations. They are considered two-part abutments. The base portion of the MUA is connected directly to the implant either with an integral screw (straight MUA) or with a separate multi-unit abutment screw (angulated abutments). Straight MUAs have a non-indexed connection with the dental implant. The angulated MUAs have an indexed connection with the dental implant. The second part of the MUA is a mating coping which is retained with a prosthetic screw. Multi-Unit Abutments are available in Straight, 17° Angulated and 30° Angulated configurations. The coping and prosthetic screw is compatible with each MUA design/configuration.

All Subject device abutments and corresponding abutment screws are pre-manufactured from Ti-6Al-4V ELI (Grade 23) titanium conforming to ASTM F136, Standard Specification for Wrought Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401) and are provided non-sterile to the user. The mesostructure/copings for Titanium base abutments are fabricated from zirconia conforming to ISO 13356, Implants for surgery — Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP).

## PERFORMANCE DATA

Non-clinical data submitted to demonstrate substantial equivalence included:

For the compatible OEM implant line, worst-case constructs of each compatible implant system in the premarket notification were subjected to static and fatigue testing according to ISO 14801 using Subject device abutments and screws.

A reverse engineering study of OEM implant bodies, abutments, and abutment screws was performed to demonstrate compatibility with the Neodent Implant System - GM Line (K163194, K180536 and K201225).

Biocompatibility cytotoxicity testing to ISO 10993-5 for the titanium base abutments is leveraged from the K220482 Predicate device and K193335 Reference device. Biocompatibility cytotoxicity testing to ISO 10993-5 for the titanium blank abutments and MUAs is leveraged from the K212664 Reference device.

{7}

Cleaning validation testing to AAMI TIR30 for titanium and zirconia constructs is leveraged from the sponsor's K220482 Predicate and K212664 Reference devices. Sterilization validation testing to ISO 17665-1 and ISO 14937 for titanium and zirconia constructs is leveraged from the sponsor's K220482 Predicate and K212664 Reference devices.

A non-clinical worst-case MRI review was performed to evaluate the sponsor's metallic previously cleared (K220482) Sherlock devices in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry O., Jana G. Delfino, and Sunder Rajan. "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795). This MRI review was leveraged for the Subject device.

No clinical or animal testing data is included in this premarket notification.

## EQUIVALENCE TO MARKETED DEVICE

Overall, the Subject device is substantially equivalent in indications and design principles to the sponsor's Predicate and Reference devices listed above. Provided at the end of this summary are tables comparing the Indications for Use Statements and the technological characteristics of the Subject, Predicate device, and Reference devices.

The Indications for Use Statement (IFUS) of the Subject device is highly similar to the sponsor's K220482 Predicate device. The IFUSs differ only in the name(s) and sizes of the compatible implant systems. Similarly, the differences between the Subject device and sponsor's K212664 Reference device IFUSs are also related to the specific device names and compatible implant lines. These minor differences do not impact substantial equivalence because the IFUSs express the same intended use to facilitate dental prosthetic restorations.

The Indications for Use Statement (IFUS) of the Subject device is similar to the K163194, K180536 and K201225 Reference devices. The IFUSs for these Reference devices include descriptions of dental implants and other dental implant abutment designs. But this difference does not impact substantial equivalence because the IFUSs express the same intended use to facilitate dental prosthetic restorations, expressed equivalently using different specific wording.

The Subject device's technological characteristics are highly similar to the sponsor's K220482 Predicate and K212664 Reference devices with the only differences being the compatible implant systems and abutment dimensions specific to those implant systems. The sponsor's Subject, Predicate and Reference devices have the same product code/regulation. The nature of an internal implant connection, offering both engaging and non-engaging connections is the same.

The Subject device titanium base abutment designs are leveraged from the sponsor's K220482 Predicate device. The Subject device implant titanium blank abutment and multi-unit abutments designs are leveraged from the sponsor's K212664 Reference device.

The sponsors Subject, K220482 Predicate and K212664 Reference devices all support cement-retained or screw-retained prosthetic restorations both in single unit and multi-unit configurations. They share the same end-user Steam Sterilization method, biocompatibility and MR Safety classification.

The K163194, K180536 and K201225 Reference devices are leveraged for support of substantial equivalence with respect to the Neodent Implant System - GM Line implant diameters, implant/abutment connection interface, platform diameter (3.0 mm) and abutment gingival height dimensions. The Subject device offers a slightly higher gingival height (6.0 mm) for 30° angled Multi-Unit Abutments than the K163194 Reference device (5.9 mm – based on K163194 device labeling). The 6.0 mm dimension of the Subject device is supported by Bench Performance Testing.

Reverse engineering and compatibility analysis was performed to validate physical compatibility with the Neodent GM® implant connection. Additionally, fatigue testing according to ISO 14801, Dentistry — Implants — Dynamic loading test for endosseous dental implants was performed to validate compatibility with the Neodent GM® implants.

{8}

Minor differences in the prosthetic platform diameter dimensions and compatible implant systems between the Subject and Predicate device do not affect substantial equivalence. These minor differences do not impact safety or effectiveness as these differences are related to the compatible OEM implant designs and are mitigated by mechanical performance testing.

## CONCLUSION

Overall, the Indications for Use statements are highly similar, differing only in the list of compatible implant system systems.

Overall, the Technological Characteristics, mode of operation and materials of the Subject device are substantially equivalent to that of the sponsor’s Predicate and Reference devices with the only change being the compatible implant systems which are supported by the K163194, K180536, and K201225 Reference devices and bench performance testing of the Subject device.

The basis for the belief that the Subject device is substantially equivalent to the sponsor’s Predicate and Reference devices and is summarized in the following comparison tables.
