The provided text describes a medical device submission (K201491) for the Neodent Implant System - Zirconia Implant System to the FDA. This document focuses on demonstrating substantial equivalence to predicate devices, rather than presenting a standalone study with specific acceptance criteria and performance results for a new AI/software device.

Therefore, the requested information about acceptance criteria, detailed device performance, sample sizes for test/training sets, ground truth establishment, expert adjudication, and MRMC studies cannot be extracted from this document as it pertains to a different type of medical device submission (dental implants and their components) and regulatory pathway (510(k) for substantial equivalence).

The document details the comparison of the subject device (Neodent Implant System - Zirconia Implant System) to predicate and reference devices in terms of indications for use, technological characteristics, and performance data from various tests. However, these are evaluations against established standards and comparisons to existing devices, not metrics of an AI's performance.

Here's what can be extracted, though it doesn't directly answer the detailed questions about AI performance criteria:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't provide a table of acceptance criteria for software performance in the typical sense (e.g., sensitivity, specificity, AUC). Instead, it presents a comparison of technological characteristics and states that the "tested subject devices exhibit a level of performance equivalent to that reviewed for the predicate devices" in mechanical testing.

Here's a summary of the performance data presented, which implies meeting an "equivalent" performance to predicates rather than specific numerical acceptance criteria for a new software.

No information is available regarding points 2-9 as they are specific to AI/software device studies to establish performance against a ground truth. This document is a 510(k) summary for a physical dental implant system and components, establishing substantial equivalence to existing devices.

Straumann® BLX Implants are suitable for endosteal implantation in the upper and lower jaw and for the functional and esthetic oral rehabilitation of edentulous and partially edentulous patients. BLX Implants can be placed with immediate function on single-tooth applications when good primary stability is achieved and with appropriate occlusal loading to restore chewing function. The prosthetic restorations are connected to the implants through the corresponding abutment components.

Straumann® Closure Caps and Healing Abutments are indicated to be placed in the patient's mouth at the end of the implant placement to protect the inner configuration of the implant and to shape, maintain and stabilize the soft tissue during the healing process. Closure caps and healing abutments should be used only with suitable implant connections. Straumann Closure Caps and Healing Abutments have a maximum duration of usage of 6 months.

Prosthetic components directly or indirectly connected to the endosseous dental implant are intended for use as an aid in prosthetic rehabilitations. Temporary components can be used prior to the insertion of the final components to maintain, stabilize and shape the soft tissue during the healing phase; they may not be placed into occlusion. Final abutments may be placed into occlusion when the implant is fully osseointegrated. BLX Temporary Abutments have a maximum duration of usage of 180 days.

Straumann® Variobase® prosthetic components directly or indirectly connected to the endosseous dental implant are intended for use as an aid in prosthetic rehabilitations. The prosthetic restoration (crowns) can be cemented onto the Straumann® Variobase® prosthetic components. A temporary restoration can be used prior to the insertion of the final components to maintain, stabilize and shape the soft tissue during the healing phase; they must be placed out of occlusion. Final abutments and restorations may be placed into occlusion when the implant is fully osseointegrated. All digitally designed copings and/or crowns for use with the Straumann® Variobase® Abutment system are intended to be sent to Straumann for manufacture at a validated milling center.

The Straumann BLX Implants are fully tapered implants manufactured utilizing the Roxolid material and are finished with SLActive® surface. The connection is identified as conical fitting with Torx style engaging feature. The prosthetic platforms are identified as RB (Regular Base) and WB (Wide Base). The implants with a RB platform have a "small top/head", and implants with WB platform have a "large top/head", whereas the internal connection is identical for both platform and all the implant diameters and lengths.

The closure cap and healing abutments are manufactured from Titanium Grade 4, per ISO 5832-2 and ISO 5832-11, and are anodized signal violet for the parts compatible with the RB platform and brown for the parts compatible with the WB platform for identification purposes. Closure caps are screwed into the implant to protect the inner configuration and shoulder of the implant during the healing phase in cases of submerged (submucosal) healing. Healing abutments are screwed into the implant to protect the inner configuration in cases of transmucosal healing and are placed out of occlusion.

The temporary abutments are manufactured from TAN and are anodized signal violet (RB platform) and brown (WB platform) for identification purposes. The temporary abutments are fixed in the implant with a basal screw which is also manufactured from TAN. The basal screw will be delivered with the temporary abutment.

BLX Variobase abutments is a two-piece abutment ultimately composed by three components: Variobase™ Abutment (Ti-base), Prosthetic restoration (coping and/or crown), and Basal Screw. The BLX Variobase Abutments are manufactured and are delivered with the corresponding basal screw. The prosthetic restoration (crowns) can be cemented onto the Variobase prosthetic components.

Basal screws are used to seat the temporary abutments and the BLX Variobase Abutments to the dental implant, and can be also be used during lab procedures to fix lab prosthetic parts on implant analogs. There is one basal screw for the RB platform and one for the WB platform. They have identical designs and differ only in color-coding (signal violet and brown) to ease the handling. They are provided along the abutments but they are also provided as standalone screws. The BLX basal screws are manufactured from TAN.

The provided text is a 510(k) premarket notification for the "Neodent Implant System - Titanium Bases For Cerec" and primarily focuses on demonstrating substantial equivalence to predicate devices, rather than establishing specific acceptance criteria and proving device performance through a standalone study with a test set, expert ground truth, or MRMC studies.

Therefore, much of the requested information regarding acceptance criteria, specific study design elements (sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance), and details on training set ground truth cannot be directly extracted from this document, as it outlines a comparison and testing against existing standards and predicate devices.

However, I can extract information about the types of performance data used to support substantial equivalence, which acts as a proxy for meeting certain "acceptance criteria" related to safety and effectiveness by demonstrating similarity to already cleared devices.

Here's a breakdown of what can be inferred:

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

The document does not present explicit acceptance criteria with numerical targets in the traditional sense, as it relies on demonstrating substantial equivalence to predicate devices and adherence to recognized standards. The "reported device performance" is framed as meeting these standards or being comparable to predicate devices.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size for Test Set: Not explicitly stated as a separate "test set" for performance evaluation in the typical sense.

  • Biocompatibility: No new testing was performed; reliance on prior clearance of the material.
  • Mechanical Testing: Not specified for this submission, but it refers to tests presented in K153624 (a reference predicate). For fatigue testing per ISO 14801, a specific number of samples (typically 5, 8, or 10, depending on the method) would be tested. The number isn't provided here.
  • Software Verification & Validation: The document states the "Titanium Base for CEREC was verified and validated with respect to its functionality and design using the Sirona validated workflow." This implies testing against the workflow, but specific sample sizes (e.g., number of test cases, scenarios) are not provided.
  • Sterilization Validation: Sterilization validation studies typically involve a defined number of biological indicators (BIs) or process challenge devices (PCDs) per run, over multiple runs. Specific numbers are not provided, only the standards used (ISO 11135, ISO 17665-1).

• Data Provenance: Not explicitly stated. Given Neodent's location in Brazil (JJGC Indústria e Comércio de Materiais Dentários SA, Curtiba, Parana, BRAZIL), it's reasonable to infer that any original data generation would have been conducted in either Brazil or relevant testing laboratories supporting their operations, or by the manufacturers of the predicate devices. The study type (retrospective/prospective) is not detailed.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. This device is a dental implant component, not an AI or diagnostic imaging device that requires expert adjudication for ground truth. Its performance is evaluated through material properties, mechanical testing, and software validation.

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

Not applicable, as this is not an AI or diagnostic imaging device for which such adjudication methods would be relevant.

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. 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. This is a physical medical device. Software verification was performed, but not as a "standalone algorithm" in the typical sense of AI performance evaluation.

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

The "ground truth" for this device's performance is established by:

• Material Specifications: Adherence to ASTM F136 for titanium alloy.
• Mechanical Performance: Demonstrating strength and fatigue resistance according to ISO 14801.
• Sterilization Efficacy: Achieving performance per ISO 11135 and ISO 17665-1 standards.
• Software Functionality: Verification and validation against predefined functional requirements within the Sirona validated workflow.
• Predicate Device Equivalence: The ultimate "ground truth" for this 510(k) is that the device is as safe and effective as its legally marketed predicate devices.

8. The sample size for the training set

Not applicable. This device is not an AI algorithm trained on data sets. The "training set" concept is not relevant here.

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

Not applicable, for the same reason as point 8.
