BLT Dental Implant Systems are intended to be placed in the upper and lower jaw to support prosthetic devices and to restore a patient's chewing function. BLT Dental Implant systems are also indicated for immediate or early implantation following extraction or loss of natural teeth. Implants can be placed with immediate function on single-tooth and/or multiple tooth applications when good primary stability is achieved and with appropriate occlusal loading to restore chewing function. The prosthetic restorations used are single crowns, bridges and partial or full dentures, which are connected to the implants through the corresponding components (abutments). In cases of fully edentulous patients, 4 or more implants must be used in immediately loaded cases.

The proposed devices, BLT Dental Implant Systems, are indicated for oral endosteal implantation in the upper and lower jaw and for the functional and esthetic oral rehabilitation of edentulous and partially dentate patients. The proposed devices can also be used for immediate or early implantation following extraction or loss of natural teeth. The proposed device contains dental implant, healing cap and abutment. The dental implant system is available in two types, NC type and RC type.

The request asks for acceptance criteria and details of the study proving these criteria are met. The provided text is a 510(k) Summary for a dental implant system. This type of submission focuses on demonstrating substantial equivalence to a predicate device, primarily through non-clinical testing and comparison of characteristics, rather than a clinical study with detailed acceptance criteria and performance metrics typically found for AI/ML devices. Therefore, much of the requested information (like effect size, ground truth, sample size for training/test sets, expert qualifications, and adjudication methods) is not applicable or unavailable from this document.

However, I can extract information related to the device's performance based on non-clinical testing and the acceptance criteria implicitly defined by compliance with recognized standards and demonstrated equivalence to the predicate device.

Here's the summary based on the provided document:

Here is the information about the acceptance criteria and the study that proves the device meets them, based on the provided text:

1. Table of Acceptance Criteria & Reported Device Performance:

The document doesn't explicitly state quantitative acceptance criteria for device performance in a table format. Instead, it refers to performance data used to demonstrate substantial equivalence to a predicate device. The performance data is therefore related to demonstrating features or durability comparable to established standards and the predicate.

2. Sample Size Used for the Test Set and Data Provenance:

The document does not specify the exact sample sizes for each of the tests (dynamic fatigue, torsion, sterility, aging, biocompatibility). It only states that the tests were performed.

The data provenance is from JJGC Indústria e Comércio de Materiais Dentários SA (dba Neodent) located in Curitiba, Parana, Brazil. The studies are prospective in nature, as they involve performing tests and gathering data specifically for this submission.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

This information is not applicable as the studies described are performance tests (mechanical, sterilization, aging, biocompatibility) of a medical device, not diagnostic studies that require expert interpretation of results to establish ground truth (e.g., image interpretation by radiologists). The "ground truth" here is defined by objective physical and chemical standards (e.g., ISO and ASTM standards).

4. Adjudication Method for the Test Set:

This information is not applicable for the type of studies presented. Adjudication methods (like 2+1, 3+1) are typically used in clinical trials or studies where human interpretation of data is involved and discrepancies need to be resolved. The described studies are objective laboratory/engineering tests.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done:

No, a Multi Reader Multi Case (MRMC) comparative effectiveness study was not performed. This type of study is typically conducted for diagnostic devices (e.g., AI in radiology) to assess the impact of AI on human reader performance. The device described (Temporary Abutments) is a physical implant component, not a diagnostic AI tool.

6. If a Standalone (Algorithm Only Without Human-in-the Loop Performance) Was Done:

This question is not applicable as the device is a physical medical device (temporary abutment), not an algorithm or AI system. Therefore, "standalone" performance in the context of an algorithm is not relevant. The performance studies conducted (fatigue, torsion, sterility, etc.) are inherently "standalone" in that they test the device itself.

7. The Type of Ground Truth Used:

The "ground truth" for the performance studies is established by objective technical standards and regulatory guidelines. This includes:

• ISO 14801 for dynamic fatigue.
• ISO 1135 for sterilization validation.
• ISO 10993-7 for ethylene oxide residuals.
• ASTM F1980 for accelerated and real-time aging.
• ISO 10993-1, 10993-5, 10993-18, 10993-12 for biocompatibility.
• FDA Guidance documents for specific test methodologies.

The "ground truth" is adherence to and performance within the limits or specifications set by these recognized standards to ensure safety and effectiveness comparable to legally marketed predicate devices.

8. The Sample Size for the Training Set:

This information is not applicable. The device is a physical medical device, not an AI model or algorithm that requires a "training set" of data.

9. How the Ground Truth for the Training Set Was Established:

This information is not applicable for the same reason as above; there is no "training set" for physical device performance.

The design data is then sent to Straumann where the fabrication of the customized abutment is performed. The TAN alloy is capable of being directly veneered once the abutment is subject to a heat treatment step by the dental laboratory technician. A finished crown may also be cemented to the subject abutments rather than by direct veneer. The abutments will be delivered with the corresponding basal screw.

The provided document (K162890) describes the regulatory submission for Straumann dental implants and associated components. However, it does not contain information about studies proving the device meets acceptance criteria for performance metrics related to diagnostic accuracy, such as sensitivity, specificity, or AUC, as these types of metrics are typically associated with diagnostic or AI-powered devices.

Instead, the document focuses on demonstrating substantial equivalence to existing legally marketed predicate devices through various non-clinical tests. The "acceptance criteria" here relate to the successful completion of these engineering and safety tests, rather than clinical performance metrics for diagnostic capability.

Therefore, the requested information cannot be fully provided in the format desired for diagnostic devices because this submission deals with dental implants, not a diagnostic AI.

However, I can extract the information related to the performance testing that was conducted to support the substantial equivalence claim.

Acceptance Criteria and Device Performance (Not applicable in the typical sense for diagnostic AI):

The document does not present acceptance criteria or reported device performance in terms of diagnostic accuracy metrics (e.g., sensitivity, specificity, AUC) because the devices (dental implants and abutments) are not diagnostic AI devices. Instead, the "performance testing" focuses on engineering, biocompatibility, and sterilization validations to demonstrate substantial equivalence to predicate devices.

Summary of Performance Testing Conducted (which can be seen as meeting "acceptance criteria" for safety and efficacy in this context):

1. Sterilization Validation (Section 5.8.1):

   • Acceptance Criteria: Validation according to applicable recommendations in the FDA guidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, issued on March 17, 2015".
   • Reported Device Performance: The sterilization process for SC Temporary Abutments, SC Variobase Abutments, and SC CARES Abutments was validated.

2. Biocompatibility Testing (Section 5.8.2):

   • Acceptance Criteria: Compliance with ISO 10993-1:2009 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', Guidance for Industry and Food and Drug Administration Staff, Document issued on: June 16, 2016". The subject devices should have identical nature of body contact, contact duration, material formulation, manufacturing processes, and sterilization methods compared to predicate devices, raising no new biocompatibility issues.
   • Reported Device Performance: The subject devices have identical biocompatibility characteristics to the primary and reference predicate devices. Therefore, no additional biocompatibility testing was required or performed.

3. Software Verification and Validation Testing (Section 5.8.3): (Applicable to CARES Visual software for abutment design, which is part of the manufacturing process, not a diagnostic AI)

   • Acceptance Criteria: Compliance with FDA guidance documents "Class II Special Controls Guidance Document: Optical Impression Systems for Computer Assisted Design and Manufacturing (CAD/CAM) of Dental Restorations" and "General Principles of Software Validation; Final Guidance for Industry and FDA Staff".
   • Reported Device Performance: Software verification and validation testing were conducted; the software for the device (CARES Visual) was considered a "moderate" level of concern.

4. Bench Testing (Section 5.8.4):

   • Acceptance Criteria: Compliance with the FDA guidance document "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" for dynamic fatigue, static strength, and insertion torque tests.
   • Reported Device Performance: Dynamic fatigue, static strength, and insertion torque tests demonstrated the Straumann® Ø2.9 mm Bone Level Tapered implants, SC Temporary Abutments, SC Variobase Abutments, and SC CARES abutments are equivalent to the predicate and reference devices.

Regarding the specific questions about diagnostic AI studies:

1. A table of acceptance criteria and the reported device performance: As explained above, not applicable for diagnostic metrics. The performance relates to engineering and safety tests.
2. Sample size used for the test set and the data provenance: Not applicable. The "tests" mentioned are non-clinical engineering and bench tests, not studies on patient data for diagnostic evaluation.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable, as there is no diagnostic test set or ground truth in this context.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
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: Not applicable, as this is not an AI-assisted diagnostic device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable to a diagnostic AI scenario. The "ground truth" for the bench tests would be the established engineering standards and physical properties of the materials.
8. The sample size for the training set: Not applicable, as there is no AI training set.
9. How the ground truth for the training set was established: Not applicable.
