    2. Sample Size Used for the Test Set and Data Provenance

    The document does not explicitly state a specific "test set" sample size for a clinical study. The performance evaluation relied on non-clinical testing and comparison to predicate devices, referencing international standards and scientific literature.

    • Data Provenance: The document does not specify a country of origin for any data beyond the manufacturer being in Japan. The studies are non-clinical, involving material testing and compatibility assessments. There is no mention of retrospective or prospective data as no human clinical testing was performed.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

    Not applicable. No human clinical testing was performed, and thus no expert ground truth was established for a clinical test set. The ground truth for material properties and performance would be derived from adherence to international standards and non-clinical testing protocols.

    4. Adjudication Method for the Test Set

    Not applicable. As no clinical test set requiring human interpretation or adjudication was used, this information is not relevant.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size

    No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The document explicitly states: "No human clinical testing was performed to support the substantial equivalence of the subject device."

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

    This device is not an AI algorithm. It is a physical dental material (zirconia block) used in a CAD/CAM system. Therefore, the concept of "standalone (algorithm only)" performance is not applicable. The performance is related to the material's physical and mechanical properties, its compatibility with the CAD/CAM system, and its ability to meet structural requirements when fabricated into an abutment.

    7. The Type of Ground Truth Used

    The ground truth for this device is based on:

    • International Standards: Adherence to established ISO standards for ceramic dental materials (ISO 6872:2015) and dynamic fatigue testing for dental implants (ISO 14801:2016).
    • Material Composition: Verification of identical chemical composition to a previously cleared reference device (KATANA Zirconia Block, K190436).
    • Biocompatibility Standards: Evaluation against ISO 10993 series and ISO 7405.
    • Engineering Design Parameters: Validation against specified design parameters for abutment post height, angulation, wall thickness, diameter, and gingival height, consistent with CAD/CAM system requirements and FDA recommendations.
    • Compatibility: Confirmation of functional compatibility with the predicate CAD/CAM system (Dentsply Sirona) and associated TiBase components through a business agreement and technical specifications.

    8. The Sample Size for the Training Set

    Not applicable. This device is a physical material, not an AI/ML algorithm that requires a "training set."

    AI/ML Overview

    The provided document describes the substantial equivalence of the CEREC Cercon 4D™ Abutment Blocks and System, primarily focusing on non-clinical performance and material characteristics, rather than an AI/ML-based device. Therefore, many of the requested elements pertaining to AI/ML device studies (e.g., sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC studies, standalone performance, training set details) are not applicable or cannot be extracted from this document.

    However, I can extract information related to the acceptance criteria and study that proves the device meets those criteria from the perspective of a medical device (specifically, a dental abutment system), even without AI elements.

    Here's the information based on the provided text, with Not Applicable (N/A) for fields that relate to AI/ML studies and are not covered in this document.


    Acceptance Criteria and Device Performance for CEREC Cercon 4D™ Abutment Blocks, CEREC Cercon 4D™ Abutment System

    The device under review is primarily a dental abutment system, and its performance is evaluated based on material properties, mechanical strength, and software integration, not on diagnostic accuracy or AI assistance.

    1. Table of Acceptance Criteria and the Reported Device Performance

    Software Validation (Wall Thickness)Internal software integration requirements for the addition of the proposed deviceMinimal wall thickness of 0.5 mm (User cannot proceed if outside)Meets requirements

    2. Sample size used for the test set and the data provenance

    • 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.

    Intended Use

    MIS Ti-base abutment is a titanium base placed onto MIS dental implants to provide support for customized cement-retained or screw retained single or multiple-unit restorations. It is used with a digitally designed mesostructure. MIS Ti-base and the mesostructure make up a two- piece abutment used in conjunction with MIS dental implants, to be placed in the upper or lower jaw arches, in order to restore masticatory function.

    Narrow platform Ti-bases are indicated for use only in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws.

    MIS short implants are to be used only with straight abutments. Mesostructures for use with the MIS Tibase abutment are to be made from inCoris ZI, IPS e.max® CAD Abutment or VITA ENAMIC® (IS), designed and manufactured using Sirona CEREC SW version 4.6.1 software.

    MIS Ti-base abutments are intended for use with the following MIS implants:

    • C1 conical connection implant system
    • V3 conical connection implant system
    • SEVEN internal hex implant system
    • M4 internal hex implant system
    • Lance+ internal hex implant system
    Device Description

    The subject MIS Ti-base abutments are endosseous dental implant abutments intended to be connected to MIS dental implants and used to support CAD/CAM customized cement-retained or screw retained single or multiple-unit restorations.

    MIS Ti-base abutments consist of a titanium base and a prosthetic screw, both made of TI-6AI-4V ELI complying with ASTM F136. The prosthetic screw tightens the finished CAD/CAM abutment to the dental implant.

    MIS Ti-base abutments are the bottom-half/base of a two-piece custom ceramic-titanium abutment consisting of a ceramic coping/mesostructure and a titanium base.

    The top-half custom ceramic coping/mesostructure or crown is intended to be fabricated from Sirona inCoris ZI zirconium oxide ceramic block, IPS e.max® CAD ceramic block, or from IPS e.max® CAD ceramic block or VITA ENAMIC® (IS) ceramic block and designed and milled using Sirona chairside Dental CAD/CAM System, with software version: CEREC SW version 4.6.1. The mesostructure design will be subject to the Sirona system controls, such as: A maximum angulation of 20° and minimum wall thickness of 0.5mm for inCoris ZI and e.max materials and 0.8mm for VITA ENAMIC material.

    It is not permitted to reduce the Ti-base's diameter, shorten the Ti-base or modify its implant-abutment connection and emergence profile in any way.

    The subject, pre-fabricated titanium base abutment is designed with interface compatibility to specific MIS dental implant systems. The subject MIS Ti-base abutments are MIS connection and internal hex connection Ti-base abutments, and their connection is compatible with MIS conical connection C1 and V3 implants, and MIS SEVEN, M4 and Lance+ internal hex implants, which are not subject to this submission and were previously cleared.

    AI/ML Overview

    This document describes a 510(k) premarket notification for the MIS Ti-base abutment. This is an FDA submission for devices that are "substantially equivalent" to predicate devices, meaning they have the same intended use and similar technological characteristics. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" are typically demonstrating this substantial equivalence through non-clinical performance data, rather than a clinical trial with specific performance metrics like sensitivity or specificity for an AI algorithm.

    Here's the breakdown based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    Since this is a substantial equivalence submission for a physical medical device (dental abutment) and not an AI algorithm, the "acceptance criteria" are related to demonstrating that the device performs as safely and effectively as a legally marketed predicate device. The performance is assessed through non-clinical testing against established standards.

    Acceptance Criteria (Demonstration of Substantial Equivalence)Reported Device Performance (Summary of Non-clinical Testing)
    BiocompatibilityThe subject device is manufactured using identical methods, facility, and raw material as the predicate (K191152). Patient contact duration and type are the same. IPS e.max® and VITA ENAMIC® (IS) mesostructure materials are cleared under K191382 and K153645 respectively, and no modifications to these materials are included. No new biocompatibility testing was required.
    Fatigue Testing (Mechanical Performance)Withstand 2,000,000 cycles without failure at a substantially equivalent load to the cited predicates, as per ISO 14801:2016. Worst-case abutments (narrowest, 20° mesostructure, various materials) were tested.
    Sterilization TestingValidated steam sterilization parameters (gravity displacement and pre-vacuum) for inCoris ZI mesostructure according to ANSI/AAMI/ISO 17665-1:2006 and ANSI/AAMI/ISO 17665-2:2009. For IPS e.max and VITA ENAMIC (IS) mesostructures, recommended parameters are based on predicate clearances K191382 and K153645.
    Software Verification and Validation (CAD/CAM Integration)Software verification and validation testing for the abutment design library demonstrated that restrictions prevent design of the mesostructure component outside of design limitations. The encrypted design library was validated to ensure established limitations are locked and cannot be modified. (For CEREC SW version 4.6.1).

    2. Sample Size Used for the Test Set and Data Provenance

    • Sample Size for Test Set: The document does not specify a "test set" in the context of clinical data for AI. For the non-clinical fatigue testing, "worst case abutments" were chosen. The exact number of samples tested for each worst-case configuration (e.g., number of narrowest abutments, number of specific mesostructures) is not explicitly stated but implied to be sufficient for ISO 14801:2016 compliance.
    • Data Provenance: Not applicable in the context of clinical or retrospective data for an AI algorithm. The performance data comes from laboratory non-clinical tests.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    • This is not applicable as this is a non-clinical device submission for a physical component, not an AI algorithm requiring expert ground truth for interpretation.

    4. Adjudication Method for the Test Set

    • Not applicable for a non-clinical device submission.

    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 device is a physical dental abutment. The software mentioned (CEREC SW version 4.6.1) is for design and milling, not a standalone AI diagnostic algorithm.

    7. The Type of Ground Truth Used

    • For fatigue testing, the "ground truth" is defined by the mechanical strength and durability requirements of the ISO 14801:2016 standard, ensuring the device can withstand chewing forces.
    • For biocompatibility, the "ground truth" is adherence to ISO 10993-1 and prior clearances of materials used.
    • For sterilization, the "ground truth" is effective sterilization as demonstrated by ANSI/AAMI/ISO 17665 standards.
    • For software verification, the "ground truth" is the established design limitations and the software's ability to enforce them.

    8. The Sample Size for the Training Set

    • Not applicable. This is not an AI algorithm that requires a training set. The software mentioned (CEREC SW) is a CAD/CAM design software, not a machine learning model developed with a training set.

    9. How the Ground Truth for the Training Set was Established

    • Not applicable as there is no training set for an AI algorithm.

    AI/ML Overview

    The provided FDA 510(k) premarket notification for "CEREC Guides" focuses on demonstrating substantial equivalence to a predicate device ("SIMPLANT Guide," K170849) through non-clinical performance data. It does not involve a multi-reader multi-case (MRMC) study or artificial intelligence (AI) performance evaluation. Therefore, many of the requested elements for an AI-based device, such as ground truth establishment by experts, adjudication methods, and MRMC study details, are not applicable here.

    Here's a breakdown of the available information relevant to acceptance criteria and study proving device performance:

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

    The document does not present a formal table of acceptance criteria with specific numerical thresholds and corresponding performance results in the format requested, typical for AI/ML device submissions. Instead, it describes various non-clinical tests conducted to support substantial equivalence. The "acceptance criteria" are implied by the successful completion of these validation tests.

    Acceptance Criterion (Implied)Reported Device Performance and Study Type
    Software Validation: Conformity with IEC 62304 and FDA guidance for software in medical devices.Validation Study: Tested to ensure conformity with IEC 62304 ("Medical device software - Software lifecycle processes") and FDA guidance "Guidance for the Content of Premarket Submissions of Software Contained in Medical Devices (May, 2005)." This included validation of input data from Galileos Implant and calibration of the compatible milling unit. (Implied: Software functions correctly and safely).
    Accuracy of Milled Guides: Deviation of apical drill position.Validation Testing: Confirmed the accuracy of the milled CEREC Guide devices by comparing the surgical guide design in CEREC SW to the apical position determined from the implant treatment plan developed using Galileos Implant dental implant planning software. (Implied: Milled guides accurately reflect the treatment plan).
    Material Strength: Mechanical properties of the PMMA material.Material Strength Analysis: Based on requirements of ISO 10477 ("Dentistry - Polymer-based crown and bridge veneering materials"), published clinical literature on intra-oral surgical drilling and bite forces, and the PMMA material characteristics of CEREC Guides and PMMA reference devices. (Implied: Material is strong enough for intended use).
    Drill Sleeve Retention: Force required to push out bonded drill sleeves.Bench Test Data: Supported the requirement that the force needed to push out the bonded CEREC Guide 3 drill sleeve exceeds intra-surgical drilling forces reported in published literature. (Implied: Drill sleeves remain secure during use).
    Biocompatibility: Safety of materials in contact with the patient.Biocompatibility Testing: Conducted on the CEREC Guide Bloc PMMA material and the finished CEREC Guide 3 (incorporating PMMA, Guide Sleeves, and Calibra® Universal adhesive). This was done with reference to the June 2016 CDRH Guidance on ISO 10993-1. (Implied: Materials are biocompatible).
    High-Level Disinfection Process Validation: Effectiveness of disinfection.Validation Testing: Validated the high-level disinfection process recommended for single-use CEREC Guides prior to use, referencing the March 2015 CDRH/CBER Guidance "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling." (Implied: Disinfection method is effective).

    2. Sample size used for the test set and the data provenance

    The document describes non-clinical bench and validation tests rather than a test set of patient data. Specific sample sizes for these engineering and material tests (e.g., number of guides milled for accuracy, number of drill sleeves tested for retention) are not detailed in this summary. The data provenance is from the manufacturer's internal testing as part of the regulatory submission process.

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

    Not applicable. This submission relies on non-clinical engineering and performance testing, not on interpretative performance (like image reading) where expert ground truth is typically established. The "ground truth" for the device's function is its design specifications and physical properties, tested through controlled experiments.

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

    Not applicable. There's no human adjudication process described, as it's not a study evaluating human interpretation or AI output against a consensus.

    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 study was done. This device, CEREC Guides, is a physical, milled surgical guide, not an AI or software-assisted diagnostic tool that would typically undergo an MRMC study to assess reader performance. The submission explicitly states: "No human clinical data was included in this premarket notification to support the substantial equivalence of the subject CEREC Guides."

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

    Not applicable. This is not an AI algorithm. Its performance is evaluated based on its physical properties, manufacturing accuracy, and integration with existing approved software and hardware. The "device" itself is the physical CEREC Guide.

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

    The "ground truth" for the performance tests is based on:

    • Design Specifications and Reference Standards: The intended design dimensions and functionalities derived from the Galileos Implant treatment planning software served as the reference for accuracy testing.
    • Established Material Properties and Biocompatibility Standards: ISO standards (e.g., ISO 10477, ISO 10993-1) and published literature for material strength and biocompatibility served as the benchmark.
    • Validated Disinfection Protocols: FDA and industry guidelines for high-level disinfection processes.

    8. The sample size for the training set

    Not applicable. This device is not an AI/ML model that requires a training set.

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

    Not applicable. As there is no AI/ML model, there is no training set or associated ground truth establishment for a training set.
