AI/ML Overview

The provided text describes the submission of a 510(k) premarket notification for the "Elos Accurate® Hybrid Base™" and "Elos Accurate® Customized Abutment" dental devices. The purpose of this submission is to demonstrate that these devices are substantially equivalent to previously marketed predicate devices. The document details the indications for use, product descriptions, a comparison of technological characteristics with predicate devices, and a summary of non-clinical testing.

Here's an analysis of the acceptance criteria and the study proving device conformity:

1. Table of Acceptance Criteria & Reported Device Performance

The acceptance criteria are not explicitly stated with numerical targets in the document. Instead, the document focuses on demonstrating substantial equivalence to predicate devices. The "reported device performance" is primarily presented as the devices meeting the same or similar functional and safety standards as the predicate devices, with specific validations for expanded compatibility and design workflows.

The "Element of Comparison" table acts as a de facto set of acceptance criteria, where the subject device's characteristics are compared against the predicate devices, and "Substantial equivalent" is the reported "performance."

Acceptance Criteria (Inferred from Predicate Equivalence)Reported Device Performance
Intended Use: Support of a prosthesis to restore chewing functionSubstantial equivalent (Same as predicate)
Abutment Designs:
Elos Accurate® Customized Abutment: 1 piece - abutment mounted on implant, fixed with screwSubstantial equivalent (Same as predicate)
Elos Accurate® Hybrid Base™: 2 piece - zirconia bonded to hybrid base mounted on implant, fixed with screwSubstantial equivalent (Same as predicate)
Prosthesis Attachment:
Customized Abutment: Abutment screw-retained to implantSubstantial equivalent (Same as predicate)
Hybrid Base: Abutment screw-retained to implant, superstructure cement-retainedSubstantial equivalent (Same as predicate)
Restoration:
Customized Abutment: Single-unitSubstantial equivalent (Same as predicate)
Hybrid Base: Single-unit, Multi-unitSubstantial equivalent (Same as predicate)
Abutment/Implant Platform Diameter (mm):
Customized Abutment: 3.0 – 4.5Customized Abutment: Implant diameter for the subject device is down to 3.0mm, which is smaller than the primary predicate device (3.2 – 7.0 for the predicate). Mechanical performance of the 3mm diameter components for both AstraTech & AstraTech EV is demonstrated in fatigue testing.
Hybrid Base: 3.4 – 4.5Hybrid Base: Substantial equivalent as Implant diameter for the subject device is within the range of the Primary Predicate Device K230317 (3.2 – 7.0 for the predicate).
Abutment Angle:
Customized Abutment: up to 20° (AstraTech), up to 30° (Straumann BLX)Substantial equivalent, as the max angulation is within the value used for Reference Device K231307 (up to 30° for the predicate).
Hybrid Base: 20° maximumSubstantial equivalent (Same as predicate).
Gingival Height: Up to 5 mmSubstantial equivalent (Same as predicate).
Materials:
Abutment: Ti-6Al-4V alloySubstantial equivalent (Same as predicate).
Screw: Ti-6Al-4V alloySubstantial equivalent (Same as predicate).
Zirconia superstructure: 3M Lava zirconia (for Hybrid Base)Substantial equivalent (Same as predicate).
Surface:
Customized Abutment: Abutment/Screw: Non-coatedThe surface of the Subject Abutment & screw is substantial equivalent to Primary Predicate Device K230317. Mechanical performance is demonstrated in fatigue testing (Note: Predicate K231307 mentions "Medicarb coating" for the screw, while K230317 mentions "non-coated, Medicarb coated").
Hybrid Base: Abutment: Anodized; Screw: Non-coatedThe surface of the Subject Abutment & screw is substantial equivalent to Primary Predicate Device K230317. Mechanical performance is demonstrated in fatigue testing (Note: Predicate K230317 also mentions "non-coated, Medicarb coated" for the screw, which is partially different but deemed equivalent due to testing).
Design Workflow: 3Shape scanner, 3Shape Abutment Designer Software (K151455)Substantial equivalent (Same as predicate). New digital libraries were validated as part of the subject submission, including: Scanner (3Shape >10um accuracy), Design library file (DME-file) with built-in limits, Design Software (3Shape Abutment Designer K151455). Testing of design limits conducted to show avoidance of designing outside specified limits.
Manufacturing Workflow: CORITEC milling unit (imes-icore)Substantial equivalent (Same as predicate).
Adhesive material (for Hybrid Base): Multilink Hybrid Abutment Cement (K130436) or Panavia V5 (K150704)Substantial equivalent (Same as predicate).
Sterilization: Full cycle pre-vacuum steam sterilization at 132 °C (270°F) for 4 mins, 20 mins dry timeSubstantial equivalent (Same as predicate). Sterilization and Dry-time studies leveraged from K230317/K231317 (material, size, geometry are substantially equivalent).
Operating principle: Connect dental implant to prosthetic crown/bridgeSubstantial equivalent (Same as predicate).

2. Sample size used for the test set and data provenance

The document does not specify a "test set" in the context of an AI/human performance study. Instead, the testing described is primarily engineering and material characterization:

  • Fatigue testing per ISO 14801: This testing involves multiple samples to assess mechanical durability. While the exact number of samples isn't given, standard ISO 14801 typically requires a significant number of samples tested to failure or for a specified number of cycles.
  • Biocompatibility testing for cytotoxicity (ISO 10993-5): This testing would use biological samples or cell lines. The document states it's leveraged from previously cleared products (K230317/K231317) on "identically manufactured abutments and prosthetic screws manufactured from the same material."
  • Sterilization validation (ISO 17665-1 & ISO 17665-2): Involves using Biological Indicators (BIs) or other validation methods, typically multiple cycles and samples. Leveraged from K230317/K231317.
  • MRI Conditional Safety Evaluations (ASTM F2052, ASTM F2119, ASTM F2213, ASTM F2182): A "worst-case assembly" was tested, implying at least one, but possibly multiple, physical assemblies to cover various MRI conditions. Leveraged from K230317/K231317.
  • Digital dentistry workflow validation: Conducted on "selected model of subject product lines," implying a representative set of designs.

Data Provenance: The data comes from non-clinical testing performed by the manufacturer (or leveraged from prior submissions by the same manufacturer, Elos Medtech Pinol A/S). The origin is Denmark (company location). The testing is prospective for the current submission but leverages retrospective data from previous clearances.

3. Number of experts used to establish the ground truth for the test set and their qualifications

This information is not applicable to this submission. The device is a physical dental abutment, not an AI/diagnostic device that generates an output requiring expert interpretation for ground truth establishment. The "ground truth" for this device relates to its physical, mechanical, and biological properties, which are established through standardized engineering and laboratory tests, not expert consensus on diagnostic images.

4. Adjudication method for the test set

This is not applicable as there is no test set involving expert interpretation or a diagnostic outcome that would require adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This is not applicable as the device is a physical dental abutment, not an AI-assisted diagnostic tool or software.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This is not applicable as the device is a physical dental abutment. The "digital dentistry workflow" involves software (3Shape Abutment Designer Software) but this is used for design and manufacturing, not for standalone diagnostic performance assessment.

7. The type of ground truth used

The "ground truth" for this engineering-focused submission is established through:

  • Engineering and dimensional analysis: Measurements and specifications of various components (abutments, implants, screws).
  • Mechanical testing: Fatigue testing per ISO 14801 to assess durability and strength under simulated physiological loading.
  • Biocompatibility testing: Standardized testing (ISO 10993-5) to confirm non-cytotoxicity.
  • Sterilization validation: Standardized testing (ISO 17665-1 & ISO 17665-2) to confirm sterility.
  • MRI compatibility testing: Standardized testing (ASTM F2052, ASTM F2119, ASTM F2213, ASTM F2182) to confirm MR conditional status.
  • Design software validation: Testing that the software (3Shape Abutment Designer) adheres to "built-in design limitations" and prevents users from exceeding them.

8. The sample size for the training set

This is not applicable. The submission is not for an AI/machine learning device that requires a training set. The descriptions of "design limitations" and "digital dentistry workflow validation" refer to the validation of software and manufacturing processes, not the training of an algorithm in the machine learning sense.

9. How the ground truth for the training set was established

This is not applicable as there is no training set for the reasons outlined above. The "design limits" mentioned for the digital dentistry workflow are predefined by Elos Medtech based on engineering principles and safety considerations for dental prosthetics.

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 approach of designing and manufacturing the Customized Abutment or zirconia superstructure (Hybrid Base) for the subject device is either according to a digital dentistry workflow or to be sent and manufactured at an FDA registered Elos Medtech approved milling facility (identical to Primary Predicate Device K230317). The subject device does not represent any new worst case, and is thereby covered by existing workflow validation submitted in K230317 and K231307. except the additional new digital libraries were validated as part of the subject submission, which included following:

  • Scanner: 3Shape scanner (accuracy >10um)

  • Design library file (DME-file) provided by Elos Medtech which includes design limits in accordance with "Instruction For Use"

  • Design Software: 3Shape Abutment Designer Software (K151455)

  • Milling Unit: CORiTEC, imes-icore milling unit

  • Zirconia Material: 3M Lava Plus Zirconia (K011394) (only relevant for Elos Accurate Hybrid Base)

X. Discussion of the Non-Clinical Testing:

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

  • . Engineering and dimensional analysis of original manufactures' components (abutments, implants & abutment screws) for determination of compatibility
  • . Fatigue testing per ISO 14801 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.
  • . The digital dentistry workflow validation was completed on selected model of subject product lines with a digital dentistry workflow including a 3Shape scanner, 3Shape Abutment Designer Software (K155415) and CORiTEC Imes-Icore milling unit. The validations were provided for the subject 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 includes design limits in accordance with Electronic Package insert -Instruction For Use, Surgical & Prosthetic Guide – Customized Abutment and Electronic Package insert - Instruction For Use, Surgical & Prosthetic Guide – Hybrid Base. The 3Shape Abutment Designer™ Software (K151455) prevents designing outside the specified design limits in the library file. Testing of design limits was conducted to show avoidance of designing outside the specified design limits.
  • . Biocompatibility testing for cytotoxicity according to ISO 10993-5. Cytotoxicity testing on identically manufactured abutments and prosthetic screws manufactured from the same material is leveraged from previously 510(k) cleared products (K230317/K231317). All tests showed the products to be non-cytotoxic.
  • Sterilization validation according to ISO 17665-1 & ISO 17665-2, demonstrating a SAL of . 10-6. The sterilization and Dry-time studies can be leveraged from K230317/K231317 to the subject Elos Accurate® Customized Abutments and Elos Accurate Hybrid Base as material, size and geometry are substantial equivalent.
  • . To verify that a worst-case assembly made of Elos Medtech devices was MR conditional, a range of tests was performed on the worst-case assembly according to ASTM F2052, ASTM F2119, ASTM F2213 and ASTM F2182. The device has been assessed at 1.5 Tesla and 3 Tesla for displacement, torque, heating and image artifact in the MRI scanner, which proved that the proposed devices are MR conditional to use when having an MRI scan. The MR conditional safety evaluations are being leveraged from prior K230317/K231317 clearance. The MR tested item is made from the same material titanium TiAl6V4 ELI and having equivalent geometry as the proposed devices. The MR tested item is representative of the subject devices since it was a much more worst-case than the subject devices.
  • To address the potential risk of damage to the implant-abutment connection geometry during the milling of the patient-matched portions of the Customized Abutment, validation testing of CAM restriction zones was conducted to show avoidance of damage or

{16}------------------------------------------------

modification of the connection geometry and locking of restriction zones from user editing in the CAM software.

XI. Conclusions:

Based on the test results and additional supporting documentation provided in this premarket notification, the subject devices demonstrated substantial equivalence to the previously listed predicate device.
