The proposed CEREC Tessera Abutment System is a modification of the previously cleared CEREC Tessera Abutment Block (K221402). The proposed CEREC Tessera Abutment Blocks are intended for fabrication of single cement-retained restorations. The proposed CEREC Tessera Abutment System (with the additional TiBase and Implant System compatibilities and change in wall thickness) is comprised of the CEREC Tessera Abutment Block, applicable TiBase, and CAD/CAM systems in both chairside (CEREC chairside software) and labside (inLab labside software) use. The CEREC Tessera Abutment Blocks are not provided as the finished, fully assembled dental implant medical device. The CEREC Tessera Abutment Blocks are materials supplied to dental professionals that must be further processed/manufactured using CAD/CAM technology and they are not intended to be reused as in the context of direct patient-applied devices and materials.

The CEREC Tessera Abutment Blocks are designed with a pre-drilled screw access channel and anti-rotation feature. The design allows for fabrication of a ceramic structure used to create 2-piece hybrid abutments and hybrid abutment crowns cemented to a TiBase used with dental implant systems. The patient-specific ceramic structure is then cemented to a TiBase to create the two-piece abutment which constitutes the final finished medical device. The following patient-specific ranges for CAD/CAM fabrication of the abutments are:

• Maximum angulation of 20°
• Minimal wall thickness of 0.5 mm
• Gingival height ranges from 0.5 mm -3.0 mm
• Minimum abutment post height (i.e. length above the gingival height) of >4 mm

• Sample Size for Test Set:
  • For Flexural Strength (Table 8.1): Not explicitly stated, but typically involves a certain number of samples to ensure statistical significance as per ISO 6872.
  • For Fatigue Testing (Table 8.2): "New fatigue testing was conducted on the worst-case combinations relating to the greatest angulation, the platform size and the gingival height for the proposed Dentsply Sirona TiBase/Dentsply Sirona Implant Systems and Third Party TiBase/Third Party Implant Systems (Camlog) combinations." The exact number of samples per test condition is not specified in the document, but standardized tests like ISO 14801 would stipulate a minimum.
  • For Sterilization Validation, Biocompatibility, and Software Validation: Not explicitly specified in terms of sample count in this summary.
• Data Provenance: The document does not specify the country of origin of the data. The tests are described as "non-clinical tests" and "performance bench testing," indicating laboratory-based studies. The document does not mention if the data is retrospective or prospective, as this distinction is more relevant for clinical studies.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. This device is not an AI/ML diagnostic tool requiring expert ground truth for image interpretation or similar. The "ground truth" (or more accurately, established performance standards) for this device is based on mechanical properties and ISO standards, which are objective and do not require expert human interpretation in the way an AI diagnostic system would.

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

Not applicable, as no human expert interpretation or consensus review is involved in the performance testing of this device (e.g., physical strength, material composition).

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; therefore, MRMC studies are irrelevant.

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

Not applicable. This is not an algorithm-based device. Its "system" aspect refers to the combination of the abutment block, TiBase, and CAD/CAM system for fabrication, not an AI algorithm. The performance described is of the physical components and the software's ability to constrain design parameters.

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

The "ground truth" for this device's performance is established by international consensus standards (e.g., ISO 6872, ISO 14801, ISO 10993, ISO 17665-1) for dental materials and implants, along with internal software integration requirements. These are objective, quantitative measures rather than subjective human interpretations or clinical outcomes data in the context of diagnostic accuracy.

8. The sample size for the training set

Not applicable. This device does not have a "training set" in the context of machine learning.

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

Not applicable. This device does not have a "training set" in the context of machine learning.
