Dental Direkt zirconium dioxide milling blanks are intended for the fabrication for long-term use.
Dental Direkt zirconium dioxide milling blanks are intended for the restorations for long-term use.

The product is not delivered sterile and cleaning, re-processing or sterilization by the user is not required. The individual variants are available in six heights (12 mm, 16 mm, 25 mm and 30 mm) to meet customer requirements. To achieve the appearance of natural tooth, the raw materials are partially mixed with a coloring of the blank. The variants of the Nacera® Pearl Natural have a color gradient from light (occlusal) to dark (tooth neck) within the blank. In this way, the color gradient of the natural tooth is reproduced.

I am sorry, but the provided text does not contain any information about acceptance criteria or a study that proves a device meets those criteria. The document is an FDA 510(k) premarket notification letter for a dental device (DD Hybridlayer (multicolored zirconia)). It discusses regulatory aspects such as the device's classification, general controls, and compliance with regulations like the Quality System (QS) regulation, Unique Device Identification (UDI) System rule, and medical device reporting (MDR).

It mentions "Non-Clinical and/or Clinical Tests Summary & Conclusions," but the content under this heading only states that "Physical characteristics are comparable since the Subject Device is a combination of the Predicate Device," without providing any specific test results, acceptance criteria, or study details.

Therefore, I cannot provide the requested information, including the table of acceptance criteria, sample sizes, expert qualifications, adjudication methods, MRMC study details, standalone performance, ground truth types, or training set information.

DD Bio Splint P HI are transparent dental milling blanks out of PMMA for the manufacture of splints, therapeutic splints and bite requlators for long-term application in the oral cavity up to 12 months.

DD medical polymers (PMMA), made from PMMA, are industrially polymerized, pre-colored or clear dental milling blanks designed for milled fabrication of bite splints (clear variant) or denture bases (gingiva-colored variants) on dental CAD/CAM systems.

The provided text is a 510(k) Summary for a medical device (DD medical polymers (PMMA)). This document focuses on demonstrating substantial equivalence to a predicate device, rather than providing a detailed study report with specific acceptance criteria and performance data in the format of a clinical or analytical study.

Therefore, the requested information cannot be fully extracted because the document is a regulatory submission for substantial equivalence based on in vitro testing and comparison to existing standards, not a standalone clinical or performance study with detailed acceptance criteria and expert reviews in the typical sense of a diagnostic device.

However, I can extract the relevant information regarding the tests performed to demonstrate substantial equivalence and what serves as the "acceptance criteria" in this context (meeting relevant standards).

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

The document does not explicitly present acceptance criteria and device performance in a direct "acceptance criteria vs. reported performance" table format. Instead, it indicates that the device's physical properties "meet the requirements of the relevant standards ISO 20795-1 and ISO 20795-2 as well as the values of the Predicate Device / Reference Device." The table on pages 8-9 provides a comparison of physical characteristics between the new device, primary predicate device, and reference device. The "acceptance criteria" here are implicitly defined by the requirements of the standards and the performance of the predicate/reference devices.

Interpretation based on the provided table (pages 8-9) and text:

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

• Sample Size: The document does not specify the exact sample sizes used for each physical test. It only states that "Non-clinical testing was performed in order to validate the product against the company's specified design requirements."
• Data Provenance: The company, Dental Direkt GmbH, is located in Spenge, Germany. The testing was performed by "an accredited testing laboratory." The specifics of whether the data were retrospective or prospective are not mentioned, but in vitro physical and biocompatibility testing is typically prospective for new device submissions.

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)

This is not applicable. The tests performed are non-clinical (physical and biocompatibility) against established international standards (ISO 20795-1, ISO 20795-2, EN ISO 10993-1, EN ISO 10993-5). Ground truth is established by these standards' methodologies and acceptance criteria, not by expert consensus in clinical interpretation.

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

This is not applicable, as the document refers to non-clinical physical and biocompatibility testing not requiring adjudication involving expert readers.

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. The device is a dental material (PMMA milling blanks) and not an AI-powered diagnostic device or an imaging product requiring human reader interpretation. No MRMC study was performed.

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 dental material and not an algorithm or AI system.

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

The "ground truth" for the non-clinical tests is based on:

• Established international standards (ISO 20795-1, ISO 20795-2, EN ISO 10993-1, EN ISO 10993-5).
• The performance values of legally marketed predicate and reference devices.
• The company's specified design requirements validated by testing.

8. The sample size for the training set

This is not applicable, as this is a physical medical device (materials) and does not involve AI or algorithms that require a training set.

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

This is not applicable, as there is no training set for this type of device.

The provided text describes Dental Direkt GmbH's K230218 510(k) submission for "DD Solid Connect® CAD/CAM Abutments (further DD Ti-Base 2CUT series)." This submission aims to demonstrate substantial equivalence to a legally marketed predicate device (K191111).

The document does not describe a study that uses a test set, expert readers, or AI performance metrics. Instead, it focuses on demonstrating substantial equivalence through a comparison of the subject device with a predicate device, relying on material, manufacturing, and general design similarities, along with performance testing according to established standards for dental implants.

Therefore, the requested information regarding acceptance criteria, device performance, sample sizes, expert involvement, adjudication, MRMC studies, standalone performance, and ground truth establishment cannot be extracted from this document as it pertains to a different type of device evaluation (substantial equivalence based on physical and functional comparison to a predicate, rather than an AI/software performance study).

The "Performance data" section (Page 4, last entry of the large table) explicitly states:

• "Fatigue testing according to ISO 14801 [FDA Recognition #4-195] and 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."
• "No new biocompatibility testing: Biocompatibilty testing for cytotoxicity according to ISO 10993-5 [FDA Recognition #2-245] leveraged from Predicate Device K191111 (worst case series)."
• "No new sterilization validation: Sterilization validation according to ISO 17665-1 [FDA Recognition #14-333], ISO 11737-1 [FDA Recognition #14-577] and ISO 11737-2 [FDA Recognition #14-540] leveraged from Predicate Device K191111 (worst case series)."
• "Reverse engineering dimensional analysis was conducted using OEM implant bodies, OEM abutments, and OEM abutment screws."

This indicates that the performance evaluation relies on bench testing (fatigue), leveraging existing biocompatibility and sterilization data from the predicate device, and dimensional analysis, not on clinical studies involving test sets, human readers, or AI.

In summary, the provided document does not contain the information required to answer the prompt as it pertains to AI/software performance studies. The device is a physical dental abutment, and its clearance is based on substantial equivalence to a predicate device through engineering and material comparisons and standardized physical testing.
