The provided 510(k) summary for the Straumann® BLX Line Extension - New Abutments is a pre-market notification to the FDA. This type of submission focuses on demonstrating substantial equivalence to existing legally marketed devices, rather than proving the device meets acceptance criteria through a traditional clinical study with defined performance targets.

Instead of "acceptance criteria," the focus here is on bench testing performance demonstrating fundamental material and structural integrity compared to predicate devices, and lack of significant differences in technological characteristics and indications for use.

Therefore, the requested information elements related to clinical studies, test sets, ground truth, and expert adjudication are not applicable in the context of this 510(k) summary, as no device-specific clinical data has been submitted to demonstrate substantial equivalence. The submission relies on performance data from bench testing and biocompatibility assessments to support the claim of substantial equivalence.

Here's the information that can be extracted from the provided text, re-interpreting "acceptance criteria" as the comparable characteristics to predicate devices and "reported device performance" as the results of the bench and biocompatibility tests.

Acceptance Criteria and Study Details for Straumann® BLX Line Extension - New Abutments

As this is a 510(k) submission primarily relying on substantial equivalence to predicate devices, the concept of "acceptance criteria" is less about meeting specific numerical performance targets in a clinical setting and more about demonstrating that the new devices do not raise new questions of safety or effectiveness. The study supporting this is primarily bench testing and biocompatibility assessments, rather than a clinical trial.

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

The "acceptance criteria" for a 510(k) are implicitly that the new device's technological characteristics and performance are substantially equivalent to a predicate device, without raising new questions of safety or effectiveness. The "reported device performance" refers to the results of the bench tests and sterility/biocompatibility validations.

Ask a specific question about this device

The Straumann CARES M-Series CAD/CAM System is indicated for the design and fabrication of single or multiple-unit implant-borne prosthetics for the restoration of partially or fully edentulous mandibles and maxillae. The system integrates multiple components of the digital dentistry workflow: scan files from Intra-Oral Scanners or Extra-Oral Scanners, CAD software, CAM software, restoration material blanks, milling machines and associated tooling and accessories. The system is used to design and fabricate CAD/CAM milled coping, crown and bridge restorations to be cemented onto Straumann® Variobase® Abutments, as well as milled abutments to be affixed to the endosseous dental implants of the Straumann® Dental Implant System using a basal screw.

The Straumann CARES M-Series CAD/CAM System is intended for the design and fabrication of dental restorations by dental laboratories by means of a digital workflow. The Straumann CARES M-Series CAD/CAM System employs optical impression files that document the topographical characteristics of teeth, traditional dental impressions, or stone models. The Straumann CARES Visual CAD software then allows the design of the desired restorations. The CAM software converts the digital restoration design into the tooling and tool path commands needed to fabricate the restoration. The CAM software also allows multiple restoration files to be combined (nested) in order to maximize the use of dental material blanks. The milling command file is encrypted prior to transfer to the M-Series mill; this encryption ensures that files generated using other CAD or CAM software cannot be used with the M-Series mill. The user will load the milling command file into the M-Series mill where it is decoded. The user loads the appropriate dental material blank and initiates the milling operation.

The provided document describes the acceptance criteria and the study that proves the Straumann CARES M-Series CAD/CAM System meets those criteria, primarily through a substantial equivalence comparison with predicate devices and various bench studies.

Here's a breakdown of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are not explicitly stated as numerical targets in the document. Instead, performance is demonstrated through a claim of "equivalence" to predicate devices, which implicitly means meeting the performance standards of those legally marketed devices. The reported device performance is presented as "Equivalent" for various features when compared to predicate devices.

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

The document does not specify a separate "test set" sample size in the context of clinical studies with patients. The studies conducted are primarily bench studies involving laboratory testing of materials and device components. The number of samples for each type of bench test (fatigue, biocompatibility, etc.) is not detailed in this summary, but these are typically standardized tests with a defined number of specimens as per the relevant ISO or FDA guidance.

The data provenance is not explicitly stated as "country of origin" or "retrospective/prospective" clinical data, as it primarily refers to bench testing data. These tests would have been performed in a controlled laboratory environment.

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

This information is not applicable. The evaluations are based on engineering and material performance specifications (bench studies) and comparison to predicate devices, not on expert clinical review of a test set for establishing ground truth in a diagnostic sense.

4. Adjudication Method for the Test Set

This information is not applicable, as the evaluation is based on bench testing and comparison to technical specifications, not human adjudication of diagnostic data.

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 information is not applicable. The device is a CAD/CAM system for fabricating dental prosthetics, not an AI-assisted diagnostic tool for human readers. Therefore, an MRMC study related to improving human reader performance with AI is not relevant to this submission.

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

The document describes the Straumann CARES M-Series CAD/CAM System as an integrated system involving CAD software, CAM software, milling machines, and material blanks. The "algorithm" component is the CAD/CAM software. The system's performance is inherently "standalone" in its function of designing and fabricating prosthetics based on input scan files, but it is a tool used by human operators (dental technicians/laboratories). The bench studies performed evaluate the output of this system (e.g., strength of the milled prosthetics), which indirectly assesses the standalone performance of the algorithms and hardware in creating the physical restorations.

7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)

For the bench studies, the "ground truth" refers to established engineering and material standards. Specifically:

• Dynamic fatigue testing: Conforming to FDA guidance and ISO 14801. The ground truth is the performance criteria defined by these standards.
• Software validation: Conforming to the requirements of IEC 62304. The ground truth is compliance with this software safety standard.
• Sterilization validation: Conforming to ISO 17665-1 and ISO/TS 17665-2. The ground truth is achieving sterility assurance levels defined by these standards.
• Biocompatibility testing: Conforming to ISO 10993-1, ISO 10993-5, ISO 10993-10, ISO 10993-11, and ISO 10993-18. The ground truth is meeting the safety criteria for biological interaction.
• Electrical safety testing: Conforming to IEC 61010-1 and IEC 61010-2-010. The ground truth is compliance with electrical safety standards.

For the substantial equivalence comparison, the "ground truth" is the performance and characteristics of the legally marketed predicate devices.

8. The Sample Size for the Training Set

The document does not refer to a "training set" in the context of machine learning. The CAD/CAM software is likely based on computational design and manufacturing principles, not on a machine learning model that requires a labeled training set derived from large datasets of past cases. Therefore, this concept is not applicable here.

9. How the Ground Truth for the Training Set was Established

As there is no "training set" in the machine learning sense, this question is not applicable. The underlying principles for the software's functionality would stem from dental anatomical knowledge, engineering mechanics, material science, and manufacturing tolerances, which form the basis of its deterministic operation.
