More Information

No
The summary describes a physical dental prosthetic component and its associated digital design workflow, but there is no mention of AI or ML being used in the design, manufacturing, or function of the device itself or the software used.

Yes.

The device is intended to provide a basis for single or multiple tooth prosthetic restorations by acting as an interface between a dental implant and a zirconia superstructure, which aims to restore function and aesthetics to the oral cavity.

No

Explanation: The device is described as an interface for attaching prosthetic dental restorations to implants. Its function is mechanical support, not diagnosis. The "scan files from Intra-Oral Scanners" is an input for the design process of the superstructure, not an output of the device itself performing diagnostic functions.

No

The device description clearly states that the Elos Accurate® Hybrid Base™ is a pre-manufactured prosthetic component made of Titanium alloy, which is a physical hardware component. While it utilizes a digital library file for design software, the core device itself is a physical object intended for implantation.

Based on the provided text, the Elos Accurate® Hybrid Base™ is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use clearly states it's for attaching to dental implants to provide a basis for prosthetic restorations. This is a mechanical function within the body, not a diagnostic test performed on samples outside the body.
  • Device Description: The description details its function as an interface between a dental implant and a zirconia superstructure, its materials, and how it's used in a dental restoration process. This aligns with a medical device used for treatment or restoration, not diagnosis.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's health condition.
  • Regulatory Context: The document references FDA regulations and guidance related to dental implants and abutments, which are typically classified as medical devices, not IVDs. It also mentions 510(k) clearances for components like design software and cement, which are relevant to medical devices.

In summary, the Elos Accurate® Hybrid Base™ is a dental prosthetic component used in the restoration of teeth, which falls under the category of a medical device, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-clinical testing data submitted (either in subject- or predicate submission) included:

  • Performance testing, ie. fatigue testing, has been performed on the Hybrid Base:
    • Astra Tech EV 3.0, the Prosthetic Screw M1.4 Astra Tech EV 3.0 and Astra Tech Implant EV 3.0S-13 mm OsseoSpeed. (intended for maxillary lateral incisors and mandibular incisors)
    • Astra Tech EV 3.6. the Prosthetic Screw M1.6 Astra Tech EV 3.6 and Astra Tech -Implant EV 3.6S-13 mm OsseoSpeed (intended for use in the posterior region)

The fatigue testing met ISO 14801 requirements according to FDA guidance for Industry and FDA Staff "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" dated May 12, 2004 and demonstrated mechanical performance comparable to the predicate device.

  • Engineering and dimensional analysis of original manufactures' components (abutments, implants & abutment screws) was performed on the subject devices for determination of compatibility.
  • Sterilization validation according to ISO 17665-1 & ISO 17665-2, demonstrating a SAL of 10-6 is leveraged from predicate device.
  • The digital dentistry workflow validation was completed on selected models of subject product line with a digital dentistry workflow including a 3Shape scanner, 3Shape Abutment Designer Software (K155415) and CORiTEC Imes-Icore milling unit. The validation was provided for the predicate K230317 abutment design library (not allowing the user to design outside the design limits set by Elos Medtech) to demonstrate use with the 3Shape Abutment Designer™ Software (K151455). The design library file (DME-file) provided by Elos Medtech included design limits in accordance with Electronic Package insert - Instruction For Use, Surgical & Prosthetic Guide. The 3Shape Abutment Designer™ Software (K151455) prevents designing outside the specified design limits in the library file. Since the subject device uses identical design and manufacturing workflow (as for the Primary Predicate Device K230317), including identical design limits build in the design library file (DME-file), the subject device does not represent any new worst case, than the worst case documented in K230317. Hence the new variants are thereby covered by existing workflow validation submitted in K230317. A design limitation test is performed with the purpose of demonstrating in 3Shape Dental System design software, that the user cannot design the zirconia superstructure for Elos Accurate Hybrid base outside the limitations built in the digital libraries relevant for this submission, provided by Elos Medtech.
  • Biocompatibility was evaluated according to ISO 10993-1 and the FDA guidance document Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" issued June 16. 2016. Based on this guidance and the common usage of the employed materials demonstrating biocompatibility via cytotoxicity testing was found sufficient. A cytotoxicity test according to ISO 10993-5 of a complete restoration produced via the described validated workflow was performed. Cytotoxicity testing on identically manufactured hybrid bases and prosthetic screws along with zirconia superstructures manufactured from the same material is leveraged from previously 510(k) cleared products (K230317). All tests showed the products to be non-cytotoxic.
  • MR Conditional labeling testing is being leveraged from predicate devices in K230317 and the subject devices do not present a new worst-case for the leveraged testing.

The zirconia superstructures for use with the Elos Accurate® Hybrid Base™ are either intended to be sent and manufactured at an FDA registered Elos Medtech approved milling facility or to be designed and manufactured according to digital dentistry workflow. The workflow system integrates multiple components of the digital dentistry workflow: scan files from Intra-Oral Scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories.

IX. Summary of the Technological Characteristics:

The subject devices provide additional restorative options for connection to existing implant platforms. The subject devices have similar Indications for Use, intended use, designs, sizes and configurations, materials, and principles of operation as the predicate devices. In order to determine nominal dimensions and tolerances of the Elos Accurate® Hybrid Base™ products, measuring- and dimensional analyses of original manufacturers' components (abutments, implants & abutment screws) have been made.

Compared to the primary predicate device, the specific language (wording) of the Indications for Use Statements is equivalent except for implant system compatibility. The implant system compatibility of the subject device is extended to include compatibility to the Astra Tech EV implant system platforms. The difference in implant system compatibility is substantiated by engineering and dimensional analysis of original manufactures' components (abutments, implants & abutment screws) for determination of compatibility and new fatigue testing.

The data included in this submission demonstrates substantial equivalence to the predicate device listed above.

Overall, the subject device has the following substantial equivalencies to the predicate device:

  • . has the same intended use.
  • . uses the same operating principle.
  • incorporates similar basic design,
  • incorporates the same or very similar materials, and
  • . is to be sterilized prior to use, using the same processes.

X. Discussion of the Non-Clinical Testing:

Non-clinical testing data submitted (either in subject- or predicate submission) included:

  • . Performance testing, ie. fatigue testing, has been performed on the Hybrid Base:
    • Astra Tech EV 3.0, the Prosthetic Screw M1.4 Astra Tech EV 3.0 and Astra Tech । Implant EV 3.0S-13 mm OsseoSpeed. (intended for maxillary lateral incisors and mandibular incisors)
    • Astra Tech EV 3.6. the Prosthetic Screw M1.6 Astra Tech EV 3.6 and Astra Tech -Implant EV 3.6S-13 mm OsseoSpeed (intended for use in the posterior region)

The fatigue testing met ISO 14801 requirements according to FDA guidance for Industry and FDA Staff "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" dated May 12, 2004 and demonstrated mechanical performance comparable to the predicate device.

  • . Engineering and dimensional analysis of original manufactures' components (abutments, implants & abutment screws) was performed on the subject devices for determination of compatibility.
  • . Sterilization validation according to ISO 17665-1 & ISO 17665-2, demonstrating a SAL of 10-6 is leveraged from predicate device.
  • The digital dentistry workflow validation was completed on selected models of subject product line with a digital dentistry workflow including a 3Shape scanner, 3Shape Abutment Designer Software (K155415) and CORiTEC Imes-Icore milling unit. The validation was provided for the predicate K230317 abutment design library (not allowing the user to design outside the design limits set by Elos Medtech) to demonstrate use with the 3Shape Abutment Designer™ Software (K151455). The design library file (DME-file) provided by Elos Medtech included design limits in accordance with Electronic Package insert - Instruction For Use, Surgical & Prosthetic Guide. The 3Shape Abutment Designer™ Software (K151455) prevents designing outside the specified design limits in the library file. Since the subject device uses identical design and manufacturing workflow (as for the Primary Predicate Device K230317), including identical design limits build in the design library file (DME-file), the subject device does not

11

represent any new worst case, than the worst case documented in K230317. Hence the new variants are thereby covered by existing workflow validation submitted in K230317. A design limitation test is performed with the purpose of demonstrating in 3Shape Dental System design software, that the user cannot design the zirconia superstructure for Elos Accurate Hybrid base outside the limitations built in the digital libraries relevant for this submission, provided by Elos Medtech.

  • . Biocompatibility was evaluated according to ISO 10993-1 and the FDA guidance document Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" issued June 16. 2016. Based on this guidance and the common usage of the employed materials demonstrating biocompatibility via cytotoxicity testing was found sufficient. A cytotoxicity test according to ISO 10993-5 of a complete restoration produced via the described validated workflow was performed. Cytotoxicity testing on identically manufactured hybrid bases and prosthetic screws along with zirconia superstructures manufactured from the same material is leveraged from previously 510(k) cleared products (K230317). All tests showed the products to be non-cytotoxic.
  • MR Conditional labeling testing is being leveraged from predicate devices in K230317 and the ● subject devices do not present a new worst-case for the leveraged testing.

XI. Conclusion:

Based on the comprehensive testing and analysis presented, the subject devices have been shown to be substantially equivalent to the predicate devices in terms of safety, performance, and intended use.
