Device Description

The Elos Accurate® Customized Abutment is a patient specific abutment intended for attaching to dental implants in order to provide basis for single- or multiple tooth prosthetic restorations. The Elos Accurate® Customized Abutment will be attached to the implant using the included Elos Prosthetic Screw and attached to the crown/coping manually by cementation. The Elos Accurate® Customized Abutment consists of an Abuttnent Blank used in fabricating of a full patient-specific abutment in Titanium alloy per ASTM F136. The Abutment Blank used in creation of the Elos Accurate® Customized Abutment has a pre-manufactured connection interface that fits directly to a pre-specified dental implant. The customized shape of the abutument is intended to be manufactured according to a digital dentistry workflow or intended to be manufactured at an FDA registered Elos Medtech approved milling facility. The Elos Accurate® Customized Abutment is delivered non-sterile and the final restoration including corresponding Elos Prosthetic Screw is intended to be sterilized at the dental clinic before it is placed in the patient. The Elos Accurate® Customized Abutment provides clinicians and laboratories with a prosthetic device that can be used in definitive (permanent) single- or multi restorations.

AI/ML Overview

The provided document, K231307 for Elos Accurate® Customized Abutment, is an FDA 510(k) premarket notification. This document focuses on demonstrating substantial equivalence to previously cleared devices rather than presenting a standalone study with defined acceptance criteria and performance metrics in the way a clinical trial or a performance study for an AI/ML powered medical device would.

The "acceptance criteria" discussed in this document pertain to the device meeting the requirements for FDA 510(k) clearance by demonstrating substantial equivalence to predicate devices, primarily through engineering, dimensional, and non-clinical testing. There is no mention of a human-in-the-loop study, a multi-reader multi-case (MRMC) study, or an AI/ML algorithm-only standalone performance study.

Therefore, many of the requested fields regarding expert adjudication, MRMC studies, and ground truth establishment for AI/ML models are not applicable to the information contained within this 510(k) submission.

Here's an interpretation of the document's contents in relation to your request, with a focus on non-clinical testing and substantial equivalence:

1. A table of acceptance criteria and the reported device performance

The "acceptance criteria" for this device are implicitly tied to demonstrating substantial equivalence to its predicates and meeting established material and dental implant abutment standards. The document doesn't present a table with numerical acceptance criteria and performance for a diagnostic AI algorithm. Instead, it lists various non-clinical tests and their successful outcomes as evidence of substantial equivalence and safety/effectiveness.

Acceptance Criteria (Implied from testing performed)Reported Device Performance (Summary from submission)
Mechanical Performance & Durability
Compliance with ISO 14801 (Fatigue Testing)Fatigue testing was conducted per ISO 14801 according to FDA guidance for Root-form Endosseous Dental Implants and Endosseous Dental Abutments. This demonstrates the device's ability to withstand cyclic loading similar to mastication forces. (Specific numerical data (e.g., load cycles, applied force) for this test is not provided in the summary but is implied to have met the standard to demonstrate equivalence to predicate.)
Dimensional Accuracy & CompatibilityEngineering and dimensional analyses were performed on original manufacturers' components (abutments, implants, & abutment screws) to determine compatibility. The nominal dimensions and tolerances of the Elos Accurate® Customized Abutment products were determined and met, ensuring proper fit with compatible implant systems as listed in Table 1 (pages 3, 7). The design library file has built-in limitations (e.g., material thickness not less than 0.4mm, gingival height not less than 0.5mm or exceed 5mm, max angulation not exceed 30°, post height not less than 4mm) which the digital workflow prevents users from exceeding, ensuring structural integrity.
Biocompatibility
Compliance with ISO 10993-5 (Cytotoxicity)Biocompatibility testing for cytotoxicity according to ISO 10993-5 was conducted. All tests on identically manufactured abutments and prosthetic screws (from the same material as subject device) showed the products to be non-cytotoxic. This data was leveraged from previous 510(k) clearances (K222044).
Sterilization
Compliance with ISO 17665-1 & 17665-2 (Sterilization Validation)Sterilization validation was performed, demonstrating a Sterility Assurance Level (SAL) of 10⁻⁶. This was leveraged from Primary Predicate Device (K171799) as material, size, and geometry are substantially equivalent. The device is delivered non-sterile and intended to be sterilized by the dental clinic.
Magnetic Resonance (MR) Compatibility
Compliance with ASTM F2052, F2119, F2213, F2182 (MR Conditional)A range of tests per ASTM standards (F2052, F2119, F2213, F2182) was performed on a worst-case assembly. The device was assessed at 1.5 Tesla and 3 Tesla for displacement, torque, heating, and image artifact. The results proved the proposed devices are MR conditional for use when having an MRI scan. This evaluation was leveraged from prior K222044 clearance.
Digital Workflow Validation
Validation of CAD/CAM Design & Manufacturing WorkflowThe digital dentistry workflow validation was completed on a selected model of the subject product line, including a 3Shape scanner, 3Shape Abutment Designer Software (K155415), and CORiTEC Imes-Icore milling unit. The validation demonstrated the use with the 3Shape Abutment Designer™ Software (K151455) and confirmed the design library file (DME-file) includes and enforces design limits in accordance with the Instructions For Use. Testing also verified avoidance of damage to implant-abutment connection geometry during milling and locking of restriction zones in CAM software.

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

  • Test Set Sample Size: The document does not specify exact "sample sizes" in terms of number of abutments or implants tested for each reported non-clinical test. The tests are general performance validations (e.g., fatigue, cytotoxicity, sterilization efficacy) and dimensional analyses that demonstrate compliance with relevant standards or a worst-case scenario. For example, fatigue testing often involves a small number of samples (e.g., 6 minimum per ISO 14801, though more are often used for statistical power) under specific loading conditions. Similarly, biocompatibility is performed on representative samples.
  • Data Provenance: The data comes from the manufacturer's (Elos Medtech Pinol A/S) internal testing and leverages data from previously cleared devices where material, size, and geometry are substantially equivalent. The provenance is therefore the manufacturer's testing facilities and associated regulatory submissions. There is no indication of different countries of origin for the data concerning these non-clinical tests. The tests are prospective in nature, as they are part of the premarket submission process.

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

This question is not applicable. The "ground truth" for this medical device (dental abutment) is established by engineering specifications, material properties, performance standards (e.g., ISO, ASTM), and clinical safety and effectiveness data from the predicates. There is no AI/ML component described that would require expert human review or "ground truth" establishment in the context of diagnostic interpretation.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

This question is not applicable as there is no human interpretation or diagnostic "test set" 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 question is not applicable. The device is a physical dental abutment and its associated digital design workflow, not an AI-powered diagnostic tool requiring human reader studies.

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

This question is not applicable. The device is not a standalone AI algorithm. The digital dentistry workflow involves CAD software and CAM software, but these are tools for designing and manufacturing the physical abutment, not for automated diagnostic interpretation or decision-making in the clinical sense of an AI/ML algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for this device's performance, as demonstrated in the submission, is based on:

  • Compliance with international standards (e.g., ISO 14801 for fatigue, ISO 10993-5 for biocompatibility, ISO 17665 for sterilization).
  • Engineering and dimensional analysis against established dental implant system specifications.
  • Physical testing results (e.g., torque, heating, displacement) for MR compatibility.
  • Validation of the digital workflow ensuring design constraints and manufacturing accuracy.
  • The fundamental demonstration is substantial equivalence to existing legally marketed predicate devices, implying that their established safety and effectiveness forms the basis of the "ground truth" for this device's intended use.

8. The sample size for the training set

This question is not applicable. This is not an AI/ML device that requires a training set for model development. The design software has built-in constraints ("design limitations" and "design limits in the library file"), which are more akin to pre-programmed rules and geometric parameters rather than a learned model from data.

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

This question is not applicable. No AI/ML training set is mentioned or implied. The "ground truth" for the design limitations within the software (e.g., minimum material thickness) would be established by engineering principles, biomechanical studies (often in labs, not clinical trials), and clinical experience with dental prosthetics, which define safe and effective design parameters.

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

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

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

{11}------------------------------------------------

  • . 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.
  • . 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 (K222044). All tests showed the products to be non-cytotoxic.
    • Tests included covered: 0
      • Elos Accurate® Customized Abutment representative for subject devices (test of primary predicate device)
      • . Non-coated prosthetic screw representative for subject device (test of primary
      • . predicate device)
      • Medicarb coated prosthetic screw representative for subject device (test of :
      • ﻴﺔ primary predicate device)
      • .
    • Sterilization validation according to ISO 17665-1 & ISO 17665-2, demonstrating a SAL of 10°. (The sterilization and Dry-time studies are conducted on the Primary Predicate Device (K171799) and can be leveraged to the subject Elos Accurate® Customized Abutments as material, size and geometry are substantial equivalent)
    • The digital dentistry workflow validation was completed on selected model 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 subject abutument 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 - In Lab Milling. The 3Shape Abutment Designer™ Software (K151455) prevents designing outside the specified design limits in the library file.

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 K222044 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 abutument blanks, validation testing of CAM restriction zones was conducted, including verification to show avoidance of damage or modification of the connection geometry, and locking of restriction zones from user editing in the CAM software.
