Dental Glass Ceramics Blocks are indicated for fabricating all-ceramic restorations such as veneers, inlay/ onlay, partial crowns, anterior crowns, posterior crowns, using the hot press technique or CAD/ CAM system.

Dental Glass Ceramics Blocks are derived from dental porcelain powder that has been processed into their final net shapes. These blanks are then being further fabricated (using hot press or CAD/CAM technologies) into all-ceramic restorations such as veneers, inlay/ onlay, partial crowns, anterior crowns, posterior crowns. The ceramics material is composed of SiO2, Li2O, K2O3 and other oxides. It also contains inorganic pigments to provide different shades on the product surface. It has three model: HT,LT,ST, and totally 23 colors(A1,A2,A3,A3.5,A4,B1,B2,B3,B4,C1,C2, C3,C4,D2,D3,D4,BL1,BL2,BL3,BL4, OM1, OM2 and OM3).

This FDA 510(k) summary is for a dental device (Dental Glass Ceramics Blocks) and focuses on demonstrating substantial equivalence to a predicate device, rather than providing a detailed study report with acceptance criteria and performance metrics for a novel AI/software device. Therefore, much of the requested information regarding AI/software performance studies (like sample sizes for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, and training set details) is not applicable to this document.

However, I can extract the relevant information regarding acceptance criteria and device performance based on the provided text for this specific type of medical device.

Device Name: Dental Glass Ceramics Blocks (HT,LT,ST)

Acceptance Criteria and Reported Device Performance:

Study to Prove Device Meets Acceptance Criteria:

A non-clinical test and biocompatibility testing were conducted.

• Physical and mechanical properties of the subject device were evaluated according to ISO 6872:2015/AMD 1:2018. This standard classifies the device into:
  • Type II: All other forms of ceramic products.
  • Class 4: Monolithic ceramic for prostheses involving partially or fully covered substructure.
  • The document states that the new model "ST" and the existing models (HT, LT, which correspond to the predicate device's models) were tested and found to have physical/mechanical properties that met the requirements of ISO 6872.
• Biocompatibility testing was performed to verify the equivalent safety of the materials used. The results comply with ISO 10993-1:2018 and FDA Guidance.

Information Not Applicable to this Submission (as it is not an AI/software device):

• Sample size used for the test set and data provenance: Not applicable. This is a physical material device, not a software/AI system. The testing involved material properties, not a "test set" of data in the AI sense.
• Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for material properties is established by standardized physical and chemical testing, not expert consensus on medical images or patient data.
• Adjudication method for the test set: Not applicable.
• If a multi-reader multi-case (MRMC) comparative effectiveness study was done: Not applicable. This is not an AI-assisted diagnostic or predictive device.
• If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
• The type of ground truth used: For material properties, the "ground truth" is defined by the objective measurements obtained through standardized physical, mechanical, and chemical tests to meet the specified ISO standard. For biocompatibility, it's defined by compliance with ISO 10993-1 and FDA guidance through specific biological evaluation tests.
• The sample size for the training set: Not applicable (no AI/machine learning involved).
• How the ground truth for the training set was established: Not applicable.
