2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not explicitly state the sample sizes used for the non-clinical tests (physical and mechanical tests, thermal shocking tests). It only indicates that "Physical and mechanical tests were conducted according to ISO 6872: 2015 and ISO 9693: 2019" and "the thermal shocking testing was conducted according to ISO 9693: 2019."
The provenance of the data (country of origin, retrospective/prospective) is not mentioned. However, since the applicant is Kuraray Noritake Dental Inc. located in Tokyo, Japan, it is reasonable to infer the testing was conducted either in Japan or under their direction.
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 as the device is a material (porcelain powder) for dental prosthetics, not a diagnostic or screening device that requires expert interpretation for ground truth establishment. The performance is assessed through objective physical and mechanical tests based on recognized international standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This is not applicable for a physical material testing study. Adjudication methods like 2+1 or 3+1 are used in studies involving human interpretation or diagnostic agreement, which is not the case here.
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. MRMC studies are typically performed for AI or diagnostic imaging devices where human readers interpret medical images. The CERABIEN MiLai is a dental material, and its performance is evaluated through non-clinical physical and mechanical testing.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. The device is a material, not an algorithm. Its performance is inherent to its physical and chemical properties and is tested in a standalone manner against established standards without human-in-the-loop interaction in the performance evaluation.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- This information is not applicable. This is a physical dental cleaning agent, not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc):
- The "ground truth" for the non-clinical performance tests was established through measured physical and chemical properties, comparative analysis against controls (positive and negative), and comparison to predicate and reference devices. This includes:
- Direct measurements of shear bond strength.
- Visual inspection for appearance and coating property.
- pH measurements.
- Observation of water solubility.
- Analytical techniques like Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray Spectroscopy (EDX) for surface comparison.
- Biocompatibility testing according to ISO standards.
8. The sample size for the training set:
- This information is not applicable. This is a physical medical device, not a machine learning model; therefore, there is no "training set."
9. How the ground truth for the training set was established:
- This information is not applicable as there is no training set for this type of device submission.

KATANA Zirconia Block is used for the fabrication of the ceramic restorations (frameworks, FCZ crowns, FCZ bridges (14Z L only), inlays, onlays and veneers).
The subject device, KATANA Zirconia Block is a pre-sintered zirconia block composed of yttrium stabilized zirconia, which is designed for CEREC milling systems. The subject device is meant to be end-user sintered after milling for the fabrication of dental restorations. KATANA Zirconia Block STML has 3 sizes (12Z, 14Z and 14Z L) and has 14 shade variations: (A1, A2, A3, A3.5, A4, B1, B2, B3, C1, C2, C3, D2, D3, NW). KATANA Zirconia Block ST has 1 size: (12Z) and has 1 shade variation: (CL). STML consists of 4 gradated shade layers and ST is mono color. They are classified as a Type II and Class 4a) material by ISO 6872.
This document describes the premarket notification for the KATANA Zirconia Block and demonstrates its substantial equivalence to previously cleared predicate and reference devices.
Here's an analysis of the provided text regarding acceptance criteria and the study that proves the device meets them:
1. A table of acceptance criteria and the reported device performance
The document provides a table (Table 3-6-3) comparing the subject device (KATANA Zirconia Block (14Z L)), the predicate device (KATANA Zirconia Block (12Z, 14Z)), and the reference device (KATANA Zirconia Disc (ST, STML)) against requirements specified in ISO 6872:2015 (Dentistry — Ceramic materials — Part 1: Dental ceramics).
Acceptance Criteria (from ISO 6872:2015) | Requirement | Reported Device Performance (Subject Device: KATANA Zirconia Block (14Z L)) |
---|---|---|
Uniformity (5.1) | The inorganic pigment(s) used to produce the color of a fired dental ceramic and any organic colorants (for color coding) shall be uniformly dispersed... Check by visual inspection. | COMPLIES |
Freedom from extraneous materials (5.2.1) | Dental ceramic materials shall be free from extraneous materials when assessed by visual inspection. | COMPLIES |
Freedom from extraneous materials (5.2.2) | Dental ceramic materials shall not have an activity concentration of more than 1.0 Bq·g-1 of 238U. Test in accordance with 7.2.2. | COMPLIES |
Flexural strength (5.4) | Equal to or greater than 500 MPa. | COMPLIES |
Chemical solubility (5.4) | Less than 100 µg/cm². | COMPLIES |
Coefficient of thermal expansion (5.4) | The coefficient of thermal expansion of the ceramics shall not deviate by more than 0.5 × 10-6 K-1 from the value stated by the manufacturer. (The value stated by the manufacturer: 9.8 × 10-6 K-1) | COMPLIES |
"COMPLIES" indicates that the test value was within the acceptable range to pass the testing in compliance with the requirements of ISO 6872:2015.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not explicitly state the sample sizes used for the bench testing. It refers to a "comparative study performed according to ISO 6872:2015," which typically involves specific sample sizes dictated by the standard for each test. The data provenance (country of origin, retrospective/prospective) is not mentioned. However, the applicant is "Kuraray Noritake Dental Inc." in Japan, suggesting the testing was likely conducted by or for this Japanese company.
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 a physical/mechanical properties test for a dental ceramic block, not a diagnostic medical device that requires expert interpretation. Therefore, there are no "experts" in the sense of medical professionals establishing a ground truth based on clinical evaluation. The ground truth for these tests is established by adhering to the standards and methods outlined in ISO 6872:2015. Visual inspections (e.g., for uniformity, absence of extraneous materials) would be performed by trained technicians or quality control personnel.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Since this is a bench testing scenario focusing on physical and chemical properties against a standard, an adjudication method for conflicting expert opinions (like 2+1 or 3+1) is not applicable. The compliance is determined by instrumental measurements and visual inspections against quantitative and qualitative criteria defined by ISO 6872:2015.
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
No MRMC comparative effectiveness study was performed. This device is a dental material (zirconia block) and not an AI-powered diagnostic tool requiring human reader assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not an algorithm-based device. It is a physical dental material. Therefore, no standalone algorithm performance study was done. The performance evaluation is based on standard material testing methods.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The ground truth for this device's performance evaluation is established by international standards (ISO 6872:2015). The performance is measured against the pre-defined limits and specifications within this standard, rather than expert consensus on clinical cases, pathology, or outcomes data.
8. The sample size for the training set
This is not an AI/machine learning device; therefore, there is no "training set" in the computational sense. The material is manufactured and tested according to quality control procedures to meet the specified standards.
9. How the ground truth for the training set was established
As there is no training set for an algorithm, this question is not applicable.
