More Information

No
The document describes a dental implant abutment system and its physical characteristics, materials, and testing. There is no mention of AI or ML in the intended use, device description, or performance studies. The "digitally designed CAD/CAM customizations" refer to standard computer-aided design and manufacturing processes, not AI/ML.

No
This device is an abutment system used to support prosthetic restorations on dental implants, not to treat a medical condition or disease.

No

Explanation: The device, Sherlock abutments, is an implant abutment system intended to provide support for prosthetic restorations. Its purpose is structural and restorative, not diagnostic. There is no mention of it being used to detect, monitor, or diagnose any medical condition.

No

The device description clearly states that Sherlock is a dental implant abutment system that includes physical components (titanium bases, screws, and zirconia superstructures) manufactured from specific materials (Ti-6Al-4V ELI alloy and zirconia). While digital design is mentioned, the core device is a physical implant abutment.

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 device is for providing support for dental prosthetic restorations in conjunction with dental implants. This is a mechanical function within the body, not a diagnostic test performed on samples taken from the body.
  • Device Description: The description details the materials and design of a dental implant abutment system, which is a physical component used in dental surgery and restoration.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.

The device is a medical device, specifically a dental implant abutment system, but it does not fit the definition of an In Vitro Diagnostic device.

PERFORMANCE DATA

Non-clinical data submitted to demonstrate substantial equivalence included:

For each 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.

Reverse engineering studies of OEM implant bodies, abutment screws to demonstrate compatibility with the implant systems listed in this premarket notification are leveraged from the K19335 (Nobel Active) and K212664 (Straumann Bone Level and Zimmer TSV) submissions.

Biocompatibility cytotoxicity testing to ISO 10993-5 for the titanium bases is leveraged from the K193335 Reference device.

Cleaning validation testing to AAMI TIR30 for a titanium and zirconia construct is leveraged from the K193335 Reference device. Sterilization validation testing to ISO 14937 for a titanium and zirconia construct is leveraged from the K193335 Reference device.

EQUIVALENCE TO MARKETED DEVICE

Overall, the Subject device is substantially equivalent in indications and design principles to the Predicate device 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 substantially equivalent to that of the K212664 Predicate device. Differences in the list of compatible implant systems do not affect the intended use as an endosseous dental implant abutment for support of a prosthesis to restore chewing function.

Similarly, the differences between the Subject device IFUS and that of each of the Reference devices are related to the specific device names and design features, validated milling centers, and the compatible implant lines. The K212108 which includes a new abutment design technology has a similarly worded Indications for Use statement, specific to the implant system of that premarket notification. None of these minor differences impact substantial equivalence because all IFUS express equivalent intended use to facilitate dental prosthetic restorations, and the indications are expressed equivalently using different specific wording.

Subject device abutments are substantially equivalent in intended use to the sponsor's K212664 Predicate device. 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. Reference devices introduce additional restorative interfaces, abutment designs with similar intended uses.

The Subject and K212664 Predicate devices are intended for single-unit or multi-unit restorations, have internal implant interface connections, and are made of Ti-6Al-4V ELI alloy (abutment screws) and are intended for cement-retained restorations. Biocompatibility of the Subject device is substantially equivalent to and supported by the Predicate device being fabricated from the same materials.

6

The Subject device includes abutment designs for implant platform diameters range from 3.3 mm, with the corresponding compatible implant body diameters ranging from 3.0 mm. Similarly, the K212664 Predicate device abutment designs supported implant platform diameters range from 3.3 mm to 6.0 mm, with the corresponding compatible implant body diameters ranging from 3.25 mm to 6.0 mm. The Subject device and K212664 Predicate devices both include abutments which may include up to a 30° post correction angle.

Compatibility with the listed implant systems is supported by the K212664 Predicate and K193335 Reference devices and through non-clinical performance testing of the Subject device.

The Subject device abutment designs are highly similar to the K212108 Reference device Titanium Base design including similar design parameters. Both the Subject and K212108 Reference devices are two-piece abutments with a titanium base and a zirconia mesostructure. Both the Subject and K212108 Reference device Titanium Base abutments have a straight titanium post with no angulation built into the post. The Subject and K212108 Reference device abutments are both offered with a cut-out portion in the post to support an angulated screwdriver access channel. The Subject device is also offered in a titanium base configuration without the cut-out providing additional post surface area for cementation. The two-piece titanium base/zirconia mesostructure abutment design is supported by the K212108 Reference device.

The Subject device is to be sterilized by the end-user, using the same methods as previously validated for the sponsor's K212664 Predicate device.

Minor differences in the abutment designs and dimensions between the Subject and Predicate do not affect substantial equivalence. These minor differences do not impact safety or effectiveness are related to the compatible OEM implant designs and are mitigated by mechanical performance testing. The new abutment designs are supported by the K212108 Reference device and mechanical performance testing of worstcase constructs.

CONCLUSION

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

Overall, the Technological Characteristics of the Subject device are highly similar to the Predicate device.

The Subject device, the Predicate device, and the Reference devices have intended use, have similar technological characteristics, and are materials. The Subject device, the 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 premarket notification demonstrate substantial equivalence to the Predicate device listed above.

Overall, the Sherlock Abutments Subject device is substantially equivalent to the Predicate device.
