IPD Dental Implant Abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for single or multiple dental prosthetic restorations.

IPD Dental Implant Abutments is a dental implant abutment system composed of dental abutments, screws, as well as other dental abutment accessories, intended to be placed into dental implants to provide support for dental prosthetic restorations.

Abutments provide basis for single or multiple tooth prosthetic restorations. They are available in a variety of connection types to enable compatibility with commercially available dental implants systems.

IPD Dental Implant Abutments includes the following categories of dental abutment designs:

• Titanium base (Interface) abutments (INC3D);
• Multi-Unit abutments (MUA);
• Overdenture Abutments (PSD);
• Temporary Abutments (PP);
• Healing Abutments (TC).

The system also includes the use of the corresponding screws intended to attach the prosthesis to the dental implant. Specifically:

• Ti Screw (TT): Used during restoration fabrication.
• TiN Screw (TTN): Used in finished restorations, with TiN coating.
• TPA Screw (TPA): Used in finished angulated restorations, with TiN coating.

The metallic components of the subject abutments and screws are made of titanium alloy conforming to ISO 5832-3 "Implant for surgery – Metallic materials – Part 3: Wrought titanium 6-aluminium 4-vanadium alloy".

The purpose of this submission is to expand IPD Dental Implant Abutments offerings with:
• New IPD's compatible dental implant systems,
• New angulations available abutment-category specific.
• New in-house TiN coating.

IPD dental implant abutments and screws are compatible with the following commercially available dental implant systems:
(Table 2. Summary of IPD abutments categories with compatibilized OEM Implant/Abutment Systems with specific reference to maximum angulation specifically included in this submission. provided in original text)

Ti Base (Interface) abutments are attached (screw-retained) to the implant/abutment and cemented to the zirconia superstructure.

The Ti Base is a two-piece abutment composed of the titanium component, as the bottom-half, and the zirconia superstructure, as the top-half. It consists of a pre-manufactured prosthetic component in Titanium alloy per ISO 5832-3, as well as the supporting digital library file for FDA-cleared design software (3Shape Abutment Designer™ Software, cleared under K151455) which enables the design of a patient-specific superstructure by the laboratory/clinician and which will be manufactured in FDA-cleared Zirconia (e.g., DD Bio Z, K142987) according to digital dentistry workflow at the point of care, or at a dental laboratory.

The design and fabrication of the zirconia superstructure for Ti Base (Interface) will be conducted using a digital dentistry workflow requiring the use of the following equipment, software and materials:
Scanner: 3D Scanner D850.
Design Software: 3Shape Abutment Designer Software, K151455.
Zirconia Material: DD Bio Z, K142987.
Milling machine/Brand: Dental Concept System Model: DC1 Milling System.
Cement: Multilink® Automix, K123397.

Ti Base (Interface) abutment design parameters for the zirconia superstructure are defined as follows:
Minimum gingival height: 1.5 mm
Minimum wall thickness: 0.43 mm
Minimum post height for single-unit restorations: 4.75 mm (1)
Maximum gingival height: 6.0 mm
Maximum angulation of the final abutment 30° (2)

The resulting final prosthetic restoration is screwed to the dental implant. All subject abutments are single-use and provided non-sterile. Final restoration (which includes the corresponding screw) is intended to be sterilized at the dental clinic before it is placed in the patient.

The provided FDA 510(k) clearance letter pertains to IPD Dental Implant Abutments, a medical device, not an AI/ML-driven software product. Therefore, the information requested regarding acceptance criteria and study data for an AI/ML device (e.g., sample size for test/training sets, expert ground truthing, MRMC studies, standalone performance) is not applicable to this document.

The document describes the device, its intended use, comparison to predicate devices, and the non-clinical performance testing conducted to demonstrate substantial equivalence. These tests are physical and chemical in nature, not related to the performance of an AI/ML algorithm.

Here's a breakdown of why an AI/ML-focused response is not possible, based on the provided text:

• Device Type: The device is "IPD Dental Implant Abutments," which are physical components used in dentistry (titanium alloy abutments, screws, designed for zirconia superstructures). It is not software, a diagnostic imaging tool, or an AI/ML algorithm.
• Purpose of Submission: The submission aims to expand compatibility with new dental implant systems and include new angulations and in-house TiN coating. This is a modification of a physical medical device, not a new AI/ML development.
• Performance Data (Section VII): This section explicitly lists non-clinical performance testing such as:
  • Sterilization validation (ISO 17665-1)
  • Biocompatibility testing (Cytotoxicity, Sensitization, Irritation per ISO 10993)
  • Reverse engineering and dimensional analysis for compatibility
  • Validation of the digital workflow and software system (but this refers to the CAD/CAM software used to design the physical abutments, not an AI/ML diagnostic tool)
  • Static and dynamic fatigue testing (ISO 14801)
  • Modified Surfaces Information
  • MRI safety review

Conclusion:

The provided document describes a 510(k) clearance for a physical dental implant component. It does not contain any information about the acceptance criteria or study design for an AI/ML driven medical device. Therefore, a table of acceptance criteria and reported device performance related to AI/ML, sample sizes for test/training sets, details on expert ground truthing, MRMC studies, or standalone performance of an algorithm cannot be extracted from this text.

The provided FDA 510(k) Clearance Letter for DESS® Dental Implants (K251280) does not contain information about acceptance criteria or a specific study proving the device meets those criteria in the context of AI/ML device performance.

The document is a clearance letter for a dental implant system, which is a physical medical device, not an AI/ML-driven diagnostic or treatment planning software. Therefore, the questions related to AI/ML device performance (such as sample size for test/training sets, data provenance, number of experts, adjudication methods, MRMC studies, standalone performance, and ground truth) are not applicable to the content provided.

The document primarily focuses on demonstrating substantial equivalence to predicate devices based on:

• Intended Use and Indications for Use
• Technological Characteristics (design, materials, surface treatment, sterilization methods, dimensions)
• Performance Data (non-clinical data such as MRI review, sterilization validation, bacterial endotoxin testing, shelf life, biocompatibility, and mechanical testing according to ISO 14801).

Since the request specifically asks for AI/ML-related performance evaluation, and the provided document is not for an AI/ML device, I cannot fulfill the request as stated with the given input.

However, I can extract the non-clinical performance data and the comparison to predicate devices, which serve as the "study" and "acceptance criteria" for this type of physical medical device in the context of a 510(k) submission.

Subject device Base Abutments are designed for fabrication of a patient-specific CAD/CAM zirconia superstructure on which a crown may be placed. They are two-piece abutments for which the second part (or top half) is the ceramic superstructure. They also may be used for support of a crown directly on the abutment.

All patient-specific custom abutment fabrication for Base Abutments and Pre-milled (Blank) Abutments is by prescription on the order of the clinician. The subject device Pre-milled (Blank) Abutments and all zirconia superstructures for use with the subject device Ti Base Interface, DESS Aurum Base, ELLIPTIBase, and DESS C-Base will be manufactured using a validated milling center or a digital dentistry workflow. A validated milling center will be under FDA quality system regulations. The digital dentistry workflow scans files from intra-oral and lab (desktop) scanners, CAD software, CAM software, titanium and ceramic material, milling machine and associated tooling and accessories.

The digital dentistry workflow uses scan files from intra-oral and lab (desktop) scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories.

The provided 510(k) summary for DESS Dental Smart Solutions focuses on demonstrating substantial equivalence to predicate devices for dental implant abutments. It primarily addresses the expansion of compatible materials, scanners, CAM software, and milling machines within an existing digital dentistry workflow. The document does not describe an AI/ML-based device that would typically have acceptance criteria related to diagnostic performance.

Therefore, many of the requested items related to AI/ML device performance (like acceptance criteria for diagnostic metrics, sample size for test sets, data provenance, expert qualifications, adjudication methods, MRMC studies, standalone performance, and training set details) are not applicable to this submission.

The acceptance criteria and supporting "study" (non-clinical data) for this device are related to its mechanical performance, biocompatibility, and integration within the digital workflow, demonstrating that the expanded components maintain the safety and effectiveness of the previously cleared predicate devices.

Here's a breakdown based on the information provided and the non-applicability of AI/ML-specific questions:

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

Since this is not an AI/ML diagnostic device, the acceptance criteria are not in terms of traditional diagnostic metrics (sensitivity, specificity, AUC). Instead, they are related to material properties, mechanical integrity, and the digital workflow's accuracy.

• Abutment design library validated to demonstrate established design limitations are locked and cannot be modified by the user. (Implies successful implementation and verification of design constraints.) |
  | CAM Restriction Zones / Manufacturing Accuracy | - Validation testing of CAM restriction zones conducted, including verification to show avoidance of damage or modifications of the connection geometry, and locking of restriction zones from user editing in CAM software. (Implies successful validation to ensure manufacturing precision and prevent damage.) |
  | Material Conformance | - Zirconia materials conform to ISO 6872.
• Titanium alloy conforms to ASTM F136.
• Co-Cr-Mo alloy conforms to ASTM F15337. (Implies materials meet standards.) |
  | Physical Dimensions | - Device encompasses the same range of physical dimensions as the predicate device. (Implies dimensional equivalence.) |

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: Not explicitly stated in terms of a "test set" for diagnostic performance. The validation involved physical testing of components (e.g., fatigue testing) and software verification. The specific number of abutments or digital design instances used for these non-clinical tests is not detailed in this summary.
• Data Provenance: Not applicable in the context of patient data for an AI/ML device. The "data" here refers to engineering and material testing results, likely conducted in controlled lab environments (implied to be in accordance with international standards like ISO and ASTM). The manufacturer is Terrats Medical SL, in Spain, so testing would likely originate from their facilities or contracted labs.

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)

Not applicable. This is not a diagnostic device requiring expert interpretation for ground truth. The "ground truth" for this device relates to engineering specifications and material science.

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

Not applicable. This is not a diagnostic device involving expert review adjudication.

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 device is not an AI-assisted diagnostic tool.

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

Not applicable. This is not an AI/ML algorithm.

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

For this device, the "ground truth" is based on:

• Engineering Specifications: Defined design parameters (e.g., minimum wall thickness, post height, angulation limits).
• Material Standards: Conformance to international standards such as ASTM F136, ISO 6872.
• Benchmarking/Predicate Equivalence: Performance is assessed against established performance of the predicate devices and OEM implant systems.
• Software Validation Logic: Verification that software correctly enforces design rules and CAD/CAM restrictions.

8. The sample size for the training set

Not applicable. This device does not involve a machine learning training set.

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

Not applicable. This device does not involve a machine learning training set.

DESS Dental Smart Solutions abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for prosthetic restorations.

All digitally designed custom abutments for use with DESS Ti Base abutments or Pre-Milled Blank abutments are to be sent to a Terrats Medical validated milling center for manufacture.

The purpose of this submission is to add components to the DESS Dental Smart Solutions system, which includes abutments, and prosthetic components cleared previously in various submissions. The previously cleared abutments and prosthetic components are compatible with a variety of original equipment manufacturer (OEM) dental implants as well as DESS Dental Smart Solutions dental implants.

This submission adds various abutments to the OEM implant lines as summarized on the following pages in Table 1 Summary of Subject Device Abutment Designs, and Table 2 Summary of Subject Device Abutment Sizes.

The subject device abutment designs include Healing Abutments, Temporary Abutments, Straight Abutments, Ti Base Abutments, AURUM Base Abutments with a screw channel design that allows easier instrument access to the abutment screw), C-Base Abutments, ELLIPTIBase CoCr Base Abutments, Pre-Milled Blank Abutments, Multi-Unit Abutments (straight), DESSLoc Abutments (Locator-type abutments), and abutment screws.

The provided document is an FDA 510(k) clearance letter for the DESS Dental Smart Solutions, which are endosseous dental implant abutments. This document primarily focuses on demonstrating substantial equivalence to previously cleared predicate devices rather than providing detailed performance data from studies against specific acceptance criteria.

Therefore, the document does not contain the information required to populate a table of acceptance criteria and proven device performance as typically expected for studies proving device efficacy or safety against performance metrics. It does not present specific quantitative performance data for the device.

Based on the content, here's what can be inferred or explicitly stated regarding the study that proves the device meets acceptance criteria:

1. Table of Acceptance Criteria and Reported Device Performance:

As noted above, the document does not present a table of specific performance acceptance criteria (e.g., accuracy, sensitivity, specificity, or other quantitative measures) and the device's reported performance against these criteria. The "Performance Data" section primarily describes non-clinical tests (MR compatibility, dimensional analysis, sterilization validation, shelf-life testing) that demonstrate that the device meets the design specifications and regulatory requirements for substantial equivalence, rather than clinical efficacy or diagnostic accuracy.

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

• Test Set Sample Size: Not applicable in the context of clinical performance data. The non-clinical tests would have their own sample sizes for their specific assessments (e.g., a certain number of abutments for sterilization validation, a certain number of parts for dimensional analysis). These specific numbers are not provided in this summary.
• Data Provenance: The "reverse engineering dimensional analysis" was done for BlueSkyBio implant connections and for Strawmann bone level connections (referenced from previous submissions). For Alpha dent, a contractual agreement provided measurements. No specific country of origin is mentioned for the data itself, but Terrats Medical SL is based in Barcelona, Spain. The document states "No clinical data were included in this submission," indicating a reliance on non-clinical testing and substantial equivalence. The studies referenced are non-clinical in nature.

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

This information is typically relevant for studies involving human interpretation or subjective assessment (e.g., imaging studies). Since "No clinical data were included in this submission," and the evaluation relies on non-clinical testing and engineering analyses, this concept of "experts establishing ground truth" as it pertains to medical image interpretation or clinical outcomes is not applicable here. Ground truth in this context would be engineering specifications and validated test methods.

4. Adjudication Method for the Test Set:

Not applicable, as there is no human interpretation or subjective assessment being adjudicated in the described non-clinical studies.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

No. The document explicitly states: "No clinical data were included in this submission." Therefore, an MRMC study comparing human readers with or without AI assistance was not performed or submitted.

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

Not applicable. This device is a physical dental implant abutment, not an AI algorithm or software that performs standalone analysis. The "DESS Dental Smart Solutions" in the product name refers to the brand of these physical components, not an intelligent software.

7. The Type of Ground Truth Used:

For the non-clinical tests described:

• Dimensional Analysis: The "ground truth" was established by reverse engineering dimensional analysis of OEM implant bodies, OEM abutments, and OEM abutment screws, or by contractual agreement providing measurements from the OEM manufacturer. This means the OEM specifications and existing components served as the reference.
• Sterilization: The ground truth for sterilization was meeting the sterility assurance level of 10-6 according to ANSI/AAMI/ISO 17665-1 and ANSI/AAMI/ISO TIR 17665-2 for moist heat, and ISO 11137-1 and ISO 11137-2 for gamma irradiation, and bacterial endotoxin testing according to ANSI/AAMI ST72.
• Material properties: Conformance to ASTM F136 for Ti-6Al-4V alloy and ASTM F1537 for Co-Cr-Mo alloy, and ISO 13356 for zirconia.

8. The Sample Size for the Training Set:

Not applicable. This is a physical medical device, not a machine learning or AI algorithm that requires a training set.

9. How the Ground Truth for the Training Set Was Established:

Not applicable, as no training set was used.

The provided text is a 510(k) Summary for the ALLONUS Tech Prosthetic, which is an endosseous dental implant abutment. It details the device's technical characteristics and compares it to predicate devices to establish substantial equivalence, rather than describing a study that proves the device meets specific acceptance criteria for a new and novel performance claim.

Therefore, many of the requested categories for acceptance criteria and study details are not directly applicable or available in this type of submission. The information provided primarily focuses on demonstrating equivalence through comparison to existing legally marketed devices, material properties, and standard performance tests for similar devices.

However, I can extract the relevant information that is available from the document for each type of device within the ALLONUS Tech Prosthetic family: Pre-Milled Blank, Ti Base, Multi-Unit Abutment, Multi-Unit Healing Cap, Multi-Unit Temporary Cylinder, and Multi-Unit Ti-Cylinder.

General Information on Acceptance Criteria and Studies for ALLONUS Tech Prosthetic (as inferred from the 510(k) Summary):

The ALLONUS Tech Prosthetic is claiming substantial equivalence to predicate devices, meaning it does not need to establish new performance criteria but rather demonstrate that it is as safe and effective as existing legally marketed devices. The "acceptance criteria" here are largely implied by the performance of the predicate devices and the relevant ISO standards for dental implant abutments. The studies performed are non-clinical bench tests.

1. Table of Acceptance Criteria (Inferred from Comparison) and Reported Device Performance:

The document presents comparisons to predicate devices to establish substantial equivalence rather than explicit acceptance criteria and corresponding performance metrics for novel claims. However, the design limits of the subject devices are compared to the design limits of the predicate devices, which act as de facto acceptance criteria in the context of substantial equivalence. The device's performance is demonstrated by meeting the standards in non-clinical testing.

Here's a generalized table summarizing this approach:

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

• Test Set Sample Size:
  • The document does not specify the exact sample sizes used for the non-clinical bench tests (fatigue, sterilization, biocompatibility, or dimensional analysis). It only states that tests were performed "for the subject device" and "of the worst-case scenario through fatigue testing."
• Data Provenance:
  • The 510(k) submission is from ALLONUS Tech Co., LTD. in the REPUBLIC OF KOREA. This implies the testing was likely conducted in or overseen by this entity.
  • The studies were non-clinical bench tests, not clinical studies involving human patients. Therefore, terms like "retrospective" or "prospective" clinical dataProvenance are not applicable here.

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

• This information is not provided in the 510(k) Summary. For non-clinical bench testing, "ground truth" is typically established by recognized international standards (e.g., ISO, ASTM) and engineering principles, rather than expert consensus on clinical cases.
• The document mentions "Dimensional analysis and reverse engineering... were performed" and "assessment of maximum and minimum dimensions... along with cross-sectional images." This suggests engineering expertise, but specific numbers or qualifications of experts are not stated.

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

• This is not applicable as the studies were non-clinical bench tests. Adjudication methods like 2+1 (two readers plus one adjudicator) are used in clinical studies, particularly for diagnostic imaging, to resolve discrepancies in expert interpretations of patient data.

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, an MRMC comparative effectiveness study was not done. This type of study (MRMC) is relevant for diagnostic AI devices that assist human interpretation of medical images or data. The ALLONUS Tech Prosthetic is a physical medical device (dental implant abutment), not an AI diagnostic tool.

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

• No, a standalone (algorithm-only) performance study was not done. This question is also typically relevant for AI/software as a medical device (SaMD). The ALLONUS Tech Prosthetic is a physical device that integrates with human dental procedures.

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

• For the non-clinical tests (fatigue, sterilization, biocompatibility), the "ground truth" is adherence to recognized international standards (ISO, ASTM) and established engineering specifications.
• For implant-to-abutment compatibility, the "ground truth" was based on dimensional analysis and reverse engineering of OEM implant bodies, abutments, and screws, comparing the subject device's design to established OEM specifications.

8. The sample size for the training set:

• This is not applicable. "Training set" refers to data used to train machine learning algorithms. The ALLONUS Tech Prosthetic is a physical medical device, not an AI/ML algorithm.

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

• This is not applicable as there is no training set for a physical medical device.

The base and the zirconia superstructure together form the final abutment. CAD/CAM customized superstructure that composes the final abutment is intended to be sent to a TruAbutment-validated milling center to be designed and milled, according to the prosthetic planning and patient clinical situation. The superstructure is cemented to the TruBase in the lab. Use "RelyX Unicem 2Automix" as an adhesive extra orally to connect.

The provided text is a 510(k) summary for the TruAbutment DS and TruBase devices. It primarily focuses on demonstrating substantial equivalence to a predicate device (TruAbutment DS, K203649) and does not detail an acceptance criteria table with reported device performance in the manner of a clinical study. The text describes non-clinical testing performed, but not a study designed to prove the device meets acceptance criteria related to a specific clinical outcome or diagnostic accuracy.

Therefore, many of the requested items (acceptance criteria table, sample size for test/training sets, data provenance, expert ground truth, adjudication, MRMC studies, standalone performance, type of ground truth) are not applicable based on the content of this 510(k) summary, which is a premarket notification for a medical device primarily based on demonstrating substantial equivalence through engineering and mechanical testing, not clinical performance or AI algorithm validation studies.

However, I can extract the information provided regarding non-clinical testing for the devices.

Acceptance Criteria and Study for TruAbutment DS & TruBase

Based on the provided 510(k) summary, the "acceptance criteria" and "study" described are focused on non-clinical mechanical performance testing and demonstration of substantial equivalence to a predicate device, rather than a clinical study proving performance against specific clinical or diagnostic accuracy metrics with human or AI components.

Here's the relevant information extracted and presented based on the document:

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

The document does not provide a table with specific quantitative acceptance criteria alongside actual reported numerical performance results for the new devices in the context of a comparative study proving their performance against such criteria. Instead, it states that "The results of the above tests have met the criteria of the standard and demonstrated substantial equivalence with the reference devices." This implies a qualitative "met standard" outcome rather than specific numerical performance data.

The tables provided describe the design limits of the devices and compare them to the predicate device, not performance data from a test:

TruAbutment DS Design Parameters (Acceptance Criteria are implied by meeting these limits)

TruBase Design Parameters (Acceptance Criteria are implied by meeting these limits)

For mechanical performance, the document states:
"Mechanical performance testing was performed according to ISO 14801. For compatible OEM implant line, worst-case constructs were subjected to static compression and compression fatigue testing. The fatigue limit data for all other implant lines demonstrated the construct strengths to be sufficient for their intended use."

This confirms that the acceptance criteria for mechanical performance were "sufficient for their intended use" as defined by ISO 14801 and worst-case testing, but quantitative results are not provided.

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 for Test Set: The document mentions "worst-case constructs" were tested for mechanical performance, and "the entire system including all variations (all compatible implant bodies, dental abutments, and fixation screws)" was evaluated for MRI environment conditions. However, specific numerical sample sizes for these tests are not provided.
• Data Provenance: The data comes from non-clinical laboratory testing following international standards (ISO 14801, ISO 17665-1/2, ISO 10993 series). The country of origin and retrospective/prospective nature are not applicable as it's not a clinical data study.

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 "ground truth" for this type of device (dental abutments) is established through adherence to engineering design specifications, material standards (ASTM F136), and performance under mechanical stress tests (ISO 14801), as well as compliance with sterilization and biocompatibility standards. It does not involve expert interpretation of images or clinical outcomes in the same way an AI diagnostic device would.

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

• This is not applicable as there is no human interpretation or subjective assessment of data requiring adjudication. Testing is based on objective measurements against engineering standards.

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 an endosseous dental implant abutment, not an AI diagnostic tool.

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

• This is not applicable. The device is a physical dental component, not an algorithm.

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

• The "ground truth" for validating these devices is adherence to engineering specifications, material properties, and performance standards (e.g., passing specific load-bearing and fatigue tests per ISO 14801, meeting biocompatibility requirements, maintaining dimensional accuracy). "Dimensional analysis and reverse engineering" were used to confirm compatibility.

8. The sample size for the training set

• This is not applicable. There is no "training set" as this is a physical medical device, not an AI/machine learning algorithm.

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

• This is not applicable for the reason above.

Summary of the Study Proving Device Meets Criteria (Based on Provided Text):

The "study" conducted was primarily non-clinical laboratory testing to demonstrate the mechanical performance, sterilization efficacy, and biocompatibility of the TruAbutment DS and TruBase devices. The objective was to show substantial equivalence to an existing legally marketed device (TruAbutment DS, K203649) by proving that the new devices meet established design limits and performance standards relevant to dental implant abutments.

• Mechanical Testing: Performed on "worst-case constructs" according to ISO 14801 for static compression and compression fatigue. The outcome was that "construct strengths [were] sufficient for their intended use."
• Sterilization Testing: Performed per ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010.
• Biocompatibility Testing: Performed per ISO 10993-1:2009, ISO 10993-5:2009, and ISO 10993-10:2010.
• MRI Environment Evaluation: A non-clinical worst-case MRI review was done using scientific rationale and published literature to assess magnetically induced displacement force and torque.
• Dimensional Analysis and Reverse Engineering: Conducted on the implant-to-abutment connection platform to assess critical design aspects and tolerances, confirming compatibility.

The overall conclusion was that the devices "met the criteria of the standard and demonstrated substantial equivalence with the reference devices," thus indicating they met their implied acceptance criteria for safety and performance as medical devices. Clinical testing was explicitly stated as "not necessary."

The provided text describes the submission of a 510(k) premarket notification for the "Elos Accurate® Hybrid Base™" and "Elos Accurate® Customized Abutment" dental devices. The purpose of this submission is to demonstrate that these devices are substantially equivalent to previously marketed predicate devices. The document details the indications for use, product descriptions, a comparison of technological characteristics with predicate devices, and a summary of non-clinical testing.

Here's an analysis of the acceptance criteria and the study proving device conformity:

1. Table of Acceptance Criteria & Reported Device Performance

The acceptance criteria are not explicitly stated with numerical targets in the document. Instead, the document focuses on demonstrating substantial equivalence to predicate devices. The "reported device performance" is primarily presented as the devices meeting the same or similar functional and safety standards as the predicate devices, with specific validations for expanded compatibility and design workflows.

The "Element of Comparison" table acts as a de facto set of acceptance criteria, where the subject device's characteristics are compared against the predicate devices, and "Substantial equivalent" is the reported "performance."

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

The document does not specify a "test set" in the context of an AI/human performance study. Instead, the testing described is primarily engineering and material characterization:

• Fatigue testing per ISO 14801: This testing involves multiple samples to assess mechanical durability. While the exact number of samples isn't given, standard ISO 14801 typically requires a significant number of samples tested to failure or for a specified number of cycles.
• Biocompatibility testing for cytotoxicity (ISO 10993-5): This testing would use biological samples or cell lines. The document states it's leveraged from previously cleared products (K230317/K231317) on "identically manufactured abutments and prosthetic screws manufactured from the same material."
• Sterilization validation (ISO 17665-1 & ISO 17665-2): Involves using Biological Indicators (BIs) or other validation methods, typically multiple cycles and samples. Leveraged from K230317/K231317.
• MRI Conditional Safety Evaluations (ASTM F2052, ASTM F2119, ASTM F2213, ASTM F2182): A "worst-case assembly" was tested, implying at least one, but possibly multiple, physical assemblies to cover various MRI conditions. Leveraged from K230317/K231317.
• Digital dentistry workflow validation: Conducted on "selected model of subject product lines," implying a representative set of designs.

Data Provenance: The data comes from non-clinical testing performed by the manufacturer (or leveraged from prior submissions by the same manufacturer, Elos Medtech Pinol A/S). The origin is Denmark (company location). The testing is prospective for the current submission but leverages retrospective data from previous clearances.

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

This information is not applicable to this submission. The device is a physical dental abutment, not an AI/diagnostic device that generates an output requiring expert interpretation for ground truth establishment. The "ground truth" for this device relates to its physical, mechanical, and biological properties, which are established through standardized engineering and laboratory tests, not expert consensus on diagnostic images.

4. Adjudication method for the test set

This is not applicable as there is no test set involving expert interpretation or a diagnostic outcome that would require adjudication.

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 as the device is a physical dental abutment, not an AI-assisted diagnostic tool or software.

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 physical dental abutment. The "digital dentistry workflow" involves software (3Shape Abutment Designer Software) but this is used for design and manufacturing, not for standalone diagnostic performance assessment.

7. The type of ground truth used

The "ground truth" for this engineering-focused submission is established through:

• Engineering and dimensional analysis: Measurements and specifications of various components (abutments, implants, screws).
• Mechanical testing: Fatigue testing per ISO 14801 to assess durability and strength under simulated physiological loading.
• Biocompatibility testing: Standardized testing (ISO 10993-5) to confirm non-cytotoxicity.
• Sterilization validation: Standardized testing (ISO 17665-1 & ISO 17665-2) to confirm sterility.
• MRI compatibility testing: Standardized testing (ASTM F2052, ASTM F2119, ASTM F2213, ASTM F2182) to confirm MR conditional status.
• Design software validation: Testing that the software (3Shape Abutment Designer) adheres to "built-in design limitations" and prevents users from exceeding them.

8. The sample size for the training set

This is not applicable. The submission is not for an AI/machine learning device that requires a training set. The descriptions of "design limitations" and "digital dentistry workflow validation" refer to the validation of software and manufacturing processes, not the training of an algorithm in the machine learning sense.

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

This is not applicable as there is no training set for the reasons outlined above. The "design limits" mentioned for the digital dentistry workflow are predefined by Elos Medtech based on engineering principles and safety considerations for dental prosthetics.

DESS Dental Smart Solutions abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for prosthetic restorations.

The purpose of this submission is to expand the DESS Dental Smart Solutions abutment system cleared under K221301 to add the ability for the subject device Base Abutments and Pre-milled (Blank) Abutments to be designed using AbutmentCAD software in the digital dentistry workflow, as well as add angulation to some of the Pre-Milled (Blank) Abutments. The subject devices are to Terrats Medical validated milling centers for manufacture, or to be designed and manufactured via a digital dentistry workflow. The digital dentistry workflow integrates multiple components: scan files from intra-oral and lab (desktop) scanners, CAD software, CAM software, titanium and ceramic material, milling machine, and associated tooling and accessories. The proposed change is to allow the subject devices to be designed using AbutmentCAD by exocad GmbH, the current workflow allows only the use of 3Shape by 3Shape A/S for the design software. Another purpose of this submission is to expand the design parameters to allow angulation (up to 30°) on Pre-milled (Blank) Abutments that are compatible with Neodent Grand Morse, Nobel Active/Nobel Parallel Conical 3.0 mm, and Straumann BLX implants. There are no changes to the abutment design or implant compatibilities. All part numbers have been cleared for manufacturing via a validated milling center and digital dentistry workflows in under K221301.

The subject device DESS Dental Solutions abutments provide a range of prosthetic solutions for dental implant restoration. DESS abutments are offered in a variety of connection types to enable compatibility with currently marketed dental implants. All abutments are provided non-sterile, and each abutment is supplied with the appropriate abutment screw (if applicable) for attachment to the corresponding implant.

Subject device Base Abutments are designed for fabrication of a patient-specific CAD/CAM zirconia superstructure on which a crown may be placed. They are two-piece abutments for which the second part (or top half) is the ceramic superstructure. They also may be used for support of a crown directly on the abutment.

All patient-specific custom abutment fabrication for Base Abutments and Pre-milled (Blank) Abutments is by prescription on the order of the clinician. The subject device Pre-milled (Blank) Abutments and all zirconia superstructures for use with the subject device Ti Base Interface, DESS Aurum Base, ELLIPTIBase, and DESS C-Base will be manufactured using a validated milling center or a digital dentistry workflow.

• . Milling machine: VHF R5 by vhf camfacture AG with DentalCAM and DentalCNC 7 software

The provided text describes a 510(k) premarket notification for DESS Dental Smart Solutions, which are dental implant abutments. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving a device's effectiveness through clinical performance studies with specific statistical acceptance criteria for accuracy, sensitivity, or specificity.

Therefore, the document does not contain the information requested regarding:

• A table of acceptance criteria and reported device performance (in terms of clinical metrics like accuracy, sensitivity, specificity).
• Sample size used for the test set or its provenance.
• Number of experts used to establish ground truth or their qualifications.
• Adjudication method for the test set.
• Multi-Reader Multi-Case (MRMC) comparative effectiveness study or its effect size.
• Standalone (algorithm only) performance.
• Type of ground truth used (expert consensus, pathology, outcomes data).
• Sample size for the training set.
• How the ground truth for the training set was established.

The study described in this document focuses on non-clinical performance data to demonstrate substantial equivalence, specifically:

1. Sterilization validation: According to ISO 17665-1, ISO 17665-2, and ISO 14937.
2. Biocompatibility testing: According to ISO 10993-5 and ISO 10993-12.
3. Fatigue testing and reverse engineering analysis: Of OEM implant bodies, OEM abutments, and OEM abutment screws to confirm compatibility. This includes fatigue testing of OEM implant bodies with patient-specific abutments made at worst-case angled conditions.
4. MR Conditional labeling.
5. Validation testing of CAM restriction zones: Including verification to show avoidance of damage or modifications of the connection geometry, and locking of restriction zones from user editing in the CAM software.
6. Software verification: Included testing of restrictions that prevent design of components outside of the stated design parameters. The abutment design library was validated to demonstrate that established design limitations and specifications are locked and cannot be modified by the user.

The acceptance criteria and reported "performance" for this submission are based on these engineering and design validations, ensuring the device meets safety and performance standards equivalent to the predicate device, K221301. The key "performance" metrics are about maintaining physical and material integrity and compatibility.

The core of the submission is to expand the DESS Dental Smart Solutions abutment system to:

• Allow design using AbutmentCAD software (in addition to 3Shape software).
• Add angulation (up to 30°) to some Pre-milled (Blank) Abutments for specific implant systems.

The document explicitly states: "No clinical data were included in this submission." and "The subject device, the predicate device, and reference devices have the same intended use, technological characteristics, and are materials. The subject device, the predicate device, and reference devices encompass the same range of physical dimensions, manufactured by similar methods, are packaged in similar materials, and are to be sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above."

Therefore, this FDA submission is for a physical medical device (dental implant abutment) and its manufacturing/design software modifications, not an AI or diagnostic device that would involve clinical performance metrics like sensitivity or specificity.

Ask a specific question about this device

IPD Dental Implant Abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for single or multiple dental prosthetic restorations.

IPD Dental Implant Abutments is a dental implant abutment system composed of dental abutments and screws intended to be placed into dental implants to provide support for dental prosthetic restorations. Abutments provide basis for single or multiple tooth prosthetic restorations. They are available in a variety of connection types to enable compatibility with commercially available dental implants systems. IPD Dental Implant Abutments includes the following categories of dental abutment designs: Healing abutments; Temporary abutments; Cementing titanium abutments; Titanium base (interface) abutments; The system also includes the corresponding Titanium Screws intended to attach the prosthesis to the dental implant.

This is a Premarket Notification (510(k)) summary for the IPD Dental Implant Abutments. This document does not describe a study proving the device meets acceptance criteria as would be found in a clinical trial for a novel AI device with specific performance metrics. Instead, it demonstrates substantial equivalence to predicate devices based on bench testing and engineering analysis.

Here's an breakdown of the information provided, tailored to your request, but emphasizing that this is not a typical AI/ML performance study:

1. Table of Acceptance Criteria and Reported Device Performance

Since this is a 510(k) for dental abutments, the "acceptance criteria" are not reported as specific performance metrics (like sensitivity/specificity for an AI model), but rather as compliance with recognized standards and demonstration of substantial equivalence to predicate devices. The "reported device performance" refers to successful completion of various non-clinical tests.

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

• Sample Size for Test Set: Not applicable in the context of human data or AI model test sets. The "test set" here refers to the physical samples of the IPD Dental Implant Abutments (and their components, potentially in various configurations) that were subjected to the specified bench and biocompatibility tests. The exact number of physical abutments, screws, or zirconia superstructures tested for each specific criterion is not detailed in this summary but would be found in the full test reports.
• Data Provenance: Not applicable in the context of country of origin for patient data. The tests were performed on the manufactured device components. The materials are specified (e.g., Titanium alloy conforming to ISO 5832-3).

Ask a specific question about this device

CEREC Cercon 4D™ Abutment System is intended for use in partially or fully edentulous mandibles and maxillae in support of single cement-retained restorations.

The system comprises three parts:

• CEREC Cercon 4D™ Abutment Block
• TiBase
• CAD/CAM system

The CEREC Cercon 4D™ ceramic structure cemented to the TiBase is recommended for two-piece hybrid abutments for single tooth restorations and hybrid abutment crowns, used in conjunction with endosseous dental implants.

The CEREC Cercon 4D Abutment Blocks, which are used for fabrication of a ceramic structure, two-piece hybrid abutments (meso-structure and crown) and abutment crowns, that are cemented to a TiBase (titanium base) used with dental implant systems. The CEREC Cercon 4D Abutment Blocks are not provided as the finished, fully assembled dental implant medical devices. The 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.

CEREC Cercon 4D™ Abutment Block are Yttria-doped zirconia blocks suitable for chairside and lab side use in fabrication of single cement-retained restorations. CEREC Ceron 4D™ Abutment Block are designed with a pre-drilled screw access channel and anti-rotation feature. The design allows for fabrication of a ceramic structure, two-piece hybrid abutments (mesostructure and crown) and abutment crowns, that are cemented to theBase (Titanium base) used with dental implant systems.

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.

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.
