NobelZygoma Multi-Unite Abutment Xeal Zygoma Screws

The NobelZygoma Multi-Unit Abutment Screws are indicated for use to secure a dental abutment or framework to a dental implant for supporting tooth replacements and are indicated as an aid in prosthetic rehabilitation.

The Subject Device NobelZygoma TiUltra Implant system is composed of three device lines: NobelZygoma TiUltra Implants, Multi-unit Abutments Xeal Zygoma and NobelZygoma Multi-unit Abutment Xeal Zygoma Screws.

The NobelZygoma TiUltra Implants are endosseous dental implants surgically placed in the zygomatic bone to provide support for prosthetic devices. They are used with patients with severe bone resorption in the maxilla to provide multi-point support of the dental reconstruction. The NobelZygoma TiUltra Implants are used to support the rehabilitation of a fully or a partially edentulous maxilla. The Subject Devices are only intended for extra-maxillary placement.

The subject Implants are made from unalloyed titanium grade 4 (ASTM F67) and present a two-level anodized surface with a soluble salt (protective) layer. Two variants of the Implants are available based on the collar angulation: the NobelZygoma 0° and the NobelZygoma 45° TiUltra Implants. The NobelZygoma 0° CC TiUltra Implants feature a conical connection platform with an internal hex (size RP). The NobelZygoma 45° Ext Hex TiUltra Implants include an external hexagonal platform (size RP).

The NobelZygoma TiUltra implants are available in lengths ranging from 30 mm to 60 mm, in 2.5 mm increments. They feature a partially threaded design. The neck portion, measuring 3.6 mm from the platform, and the shaft portion which varies depending on the implant length, are unthreaded. For all implant lengths, threading consistently begins at the apex and extends 18 mm coronally.

The NobelZygoma TiUltra Implants are co-packed with an implant mount, which is attached via a pre-assembled implant mount screw to the platform of the implant.

The Multi-unit Abutments Xeal Zygoma are premanufactured prosthetic components intended to be connected to the compatible NobelZygoma TiUltra Implants to support the placement of a dental prosthesis.

The Multi-unit Abutment (MUA) Xeal Zygoma are made from Titanium alloy (Ti-6Al-4V (90% titanium, 6% aluminum, 4% vanadium, ASTM F136) and feature a non-porous oxide layer with a soluble salt (protective) layer. The Multi-unit Abutments Xeal Zygoma are attached to the respective NobelZygoma TiUltra Implants by the compatible NobelZygoma Multi-unit Abutment Xeal Zygoma Screw.

The Multi-unit Abutment Xeal Zygoma are available in four different angulations (straight or 0°, 17°, 45° and 60°) and in different heights ranging from 3 to 9mm (2mm increase). The 45° and 60° angulations are used with the NobelZygoma 0° TiUltra implants, while the Straight (or 0°) and 17° angulations are compatible with the NobelZygoma 45° TiUltra Implants. The 17° MUA is only available in two heights (3 and 5mm).

The Multi-unit Abutments Xeal Zygoma are provided sterile and co-packed with the respective abutment handle and NobelZygoma Multi-Unit Abutments Xeal Zygoma Screw.

The NobelZygoma Multi-unit Abutment Xeal Zygoma Screws are dental implant screws designed to fasten dental implant system components to a dental implant or to another component.

The subject screws are made of titanium alloy (Ti-6Al-4V (90% titanium, 6% aluminum, 4% vanadium, ASTM F136) and are partially DLC-coated. They are available in different design and sizes to fit the different Multi-unit Abutments Xeal Zygoma.

The provided document is a 510(k) Clearance Letter from the FDA for the "NobelZygoma TiUltra Implant system." This type of document primarily focuses on establishing substantial equivalence to previously cleared predicate devices, rather than explicitly detailing acceptance criteria and presenting a single, comprehensive study proving the device meets those criteria.

However, the document does contain information about non-clinical and clinical testing performed to support the substantial equivalence claim. I will extract the relevant information to answer your questions to the best of my ability, acknowledging that not all requested details may be explicitly present in this type of regulatory submission summary.

Here's a breakdown of the requested information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Note: The document does not explicitly list acceptance criteria in a formal table with pass/fail values. Instead, it describes various tests performed and compares the subject device's performance to predicate devices or established standards. The "Reported Device Performance" column reflects the summary of findings from the validation studies described.

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

• Test Set Sample Size: The document does not provide specific sample sizes for the non-clinical tests (fatigue, torque, MR, biocompatibility, packaging, sterilization, endotoxin, surface roughness). These are typically determined by relevant standards.
  • For clinical published literature, the sample sizes varied:
    • Three studies on non-full arch applications involved 176 similar zygomatic implants.
    • Systematic literature review on quad configuration reported data for a mean implant survival rate (implies a larger, unspecified number of cases).
    • Two clinical studies involving Nobel Biocare zygomatic implants: n=15 (minimum 79 months follow-up) and n=302 (mean 7.9 years follow-up).
    • A total of 40 clinical publications were provided to support the established history of safe clinical use (number of implants/patients unspecified in this summary).
    • Seven clinical cases with a total of 16 NobelZygoma TiUltra implants were presented.
    • 36 clinical publications on NobelReplace and TiUltra implant family (number of implants/patients unspecified in this summary).
• Data Provenance:
  • Clinical Studies: Published literature (implies peer-reviewed, multi-center, potentially international data).
  • Real-world evidence (RWE): Post-market surveillance for the Subject Devices from July 2024 to May 2025. This is prospective data specific to the subject device after initial market introduction (likely under a different clearance or within a broader market).
  • Clinical Case Studies: Seven cases presented directly by the submitter.
  • The document implies that data from various regions would be included in "published literature" and "post-market surveillance." No specific countries of origin are mentioned beyond "Nobel Biocare" (Sweden/Switzerland) and "Southern Implants (Pty) Ltd" (implies South Africa). The nature of most clinical data is retrospective (published studies, post-market surveillance).

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

The document does not specify the number of experts used to establish ground truth for the test set (clinical studies). Clinical studies typically rely on diagnoses and assessments made by treating clinicians (dental surgeons, prosthodontists) based on established medical practices and diagnostic criteria, rather than a separate "ground truth" panel for the study itself, unless it's a specific adjudication or consensus study. Such details are usually found within the full study protocols and reports, which are not part of this 510(k) summary.

4. Adjudication Method (e.g., 2+1, 3+1, none) for the Test Set

The document does not specify any adjudication methods for the clinical data presented. This information would typically be detailed in the methodology sections of the individual clinical studies or systematic reviews referenced, which are not provided in this summary.

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

The document describes a dental implant system (hardware), not an AI-powered diagnostic or assistive tool. Therefore, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study focusing on human reader improvement with/without AI assistance is not applicable and was not performed.

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

This question is not applicable as the device is a dental implant system, not an algorithm.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

• Non-Clinical Tests: Ground truth is based on established engineering and materials science principles, international standards (ISO, ASTM), and FDA guidance documents. Performance is evaluated against these benchmarks.
• Clinical Performance Data: Ground truth is primarily based on outcomes data, specifically:
  • Implant survival rate: Directly reported as percentage (e.g., 97.4%, 100%, 89.9%, 99.5%).
  • Reported adverse events and complications: Clinical observations and diagnoses by treating dentists/surgeons. Resolution of these events are considered outcomes.
  • Osseointegration: Inferred from success rates and lack of failure/complaints related to implant stability.
  • Patient esthetics and chewing function: These are indications, and clinical data indirectly supports their achievement through successful implant function.

8. The Sample Size for the Training Set

The concept of a "training set" is typically associated with machine learning or AI algorithms. Since this is a physical medical device (dental implant system), it primarily relies on engineering design, materials science, and clinical validation. Therefore, a "training set" in the context of an algorithm is not applicable. The development and testing would involve design iterations and validation studies, but not an algorithmic training process with a distinct training set.

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

As noted in point 8, the concept of a "training set" in the context of an AI/ML algorithm is not applicable to this physical device. Therefore, the establishment of ground truth for such a set is also not applicable. The "ground truth" for the device's design and performance validation is derived from established scientific principles, pre-clinical testing, and clinical outcomes for the device itself and its predicates.

Ask a specific question about this device

MIS dental implant system is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore masticatory function. When a one-stage surgical procedure is applied, the implant may be immediately loaded when good primary stability is achieved and the occlusal load is appropriate.

Narrow implants (Ø3.30mm) are indicated for use in surgical and restorative applications for placement only in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws, to provide support for prosthetic devices such as artificial teeth. Mandibular central and lateral incisors must be splinted if using two or more narrow implants adjacent to one another.

The subject devices, MIS Implants, are supplied sterile and packaged together with a cover screw which can be connected to the implant during the initial healing period after implant placement.

The implants and cover screws are made of titanium alloy (Ti-6Al-4V ELI complying with standard ASTM F136-13 - Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant). The design and material of the implants and cover screws remain unchanged since most recently cleared 510(k).

The implants are also used with a wide range of previously cleared abutments which are sold separately.

This document is a 510(k) clearance letter for dental implants, not an AI/software as a medical device (SaMD) submission. Therefore, it does not contain the information requested regarding acceptance criteria and study proving device meets acceptance criteria for an AI/SaMD product.

The document discusses dental implants and their physical and material characteristics, regulatory classifications, predicate devices, and performance testing for mechanical properties, sterility, and packaging. The "Performance Data" section specifically mentions "Hydrophilicity testing" for "wet-packed implants" and other physical tests, but none of these relate to AI/SaMD performance metrics like sensitivity, specificity, or reader studies.

Therefore, I cannot provide a table of acceptance criteria, sample sizes for test sets, expert qualifications, or details on MRMC studies, standalone performance, or ground truth establishment relevant to an AI/SaMD product based on the provided text.

The prompt asks for information that this type of medical device submission (dental implants) would not typically include.

The provided FDA 510(k) clearance letter and its associated summary for the Neodent Implant System - Zirconia Implant System contain extensive information about the device, its intended use, and comparisons to predicate devices. However, it does not include specific acceptance criteria with numerical thresholds directly stated within the tables, nor does it detail a study that directly proves the device meets such criteria in terms of performance metrics like sensitivity, specificity, or image quality assessments.

Instead, the submission focuses on demonstrating substantial equivalence to predicate devices through various tests, implying that if the new device performs similarly to or better than previously cleared devices, it meets the necessary standards. The performance testing section describes the types of tests conducted (e.g., dynamic fatigue, torsion, insertion, pull-out, and software validation), but it does not present clear quantitative acceptance criteria or the specific performance results in a comparative table format.

Therefore, many of the requested fields cannot be directly extracted from the provided text as they pertain more to the performance evaluation of AI/software in interpreting medical images, which is not the primary focus of this dental implant submission.

Here's an attempt to answer the questions based on the available information, noting where information is not explicitly provided in the document:

Acceptance Criteria and Device Performance Study for Neodent Implant System - Zirconia Implant System

The FDA 510(k) summary for the Neodent Implant System - Zirconia Implant System focuses on demonstrating substantial equivalence to predicate devices through a combination of bench testing, software validation, MRI compatibility, biocompatibility, and sterilization validation. It does not present specific quantitative acceptance criteria or performance metrics directly from a comparative study in the way one might expect for an AI/software-based medical device (e.g., sensitivity, specificity thresholds). Instead, the "acceptance criteria" are implicitly met by demonstrating that the proposed devices perform at a level substantially equivalent to legally marketed predicate devices under standardized testing conditions.

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

As mentioned, explicit numerical acceptance criteria and reported device performance in a comparative table (e.g., for diagnostic accuracy) are not provided in this 510(k) summary. The summary indicates that tests were conducted according to relevant ISO standards and FDA guidance, and the results demonstrated that the subject devices exhibit a level of performance substantial equivalent to the predicate and reference devices.

Below is a conceptual table based on the types of tests mentioned, noting that specific numerical acceptance criteria and performance data are not detailed in the provided text.

S.I.N. Dental Implant System is intended for placement in the maxillary or mandibular arch to provide support for single-unit or multi-unit restorations. When a one-stage surgical approach is applied, the S.I.N. dental implants are intended for immediate loading when good primary stability is achieved and with appropriate occlusal loading.

S.I.N. Dental Implant System implants with lengths of 18, 20, 22 or 24mm may be tilted up to 30º. When used in the mandible or maxilla with implants with lengths of 18, 20, 22 or 24 mm at an angulation of 30º, a minimum of four implants must be used and must be splinted. When placed in the maxilla with lengths of 18, 20, 22 or 24 mm at angulations between 0º and less than 30º, the S.I.N. Dental Implant System implants are only indicated for multiple unit restoration in splinted applications that utilize at least two implants.

The purpose of this submission is to add components to the S.I.N. Dental Implant System, which includes various endosseous implants with 16° Morse tapers interface connection. This submission adds to the S.I.N. Dental Implants System, the Versalis S implants line.

The Versalis S implant line has the Versalis S and Versalis S Plus implants, and both have a Morse taper connection with an internal 16° cone taper. The Versalis S implants have implant body lengths from 8.5 to 24mm and body diameter Ø from 3.5 to 7.0mm., they are manufactured from unalloyed titanium conforming to ASTM F67, with a double acid-etched surface treatment. The Versalis S Plus implants have implant body lengths from 8.5 to 24mm and body diameter Ø from 3.5 to 7.0mm., they are manufactured from unalloyed titanium conforming to ASTM F67, with a double acid-etched surface treatment plus hydroxyapatite surface coating.

All subject device dental implants are manufactured from unalloyed titanium conforming to ASTM F67 Standard Specification for Unalloyed Titanium for Surgical Implant Applications (UNS R50250, UNS R50400, UNS R50550, UNS R50700), Grade 4. The material used to manufacture the dental implants in this submission (conforming to ASTM F67) is identical to the material used to manufacture the device implants cleared in primary predicate K170392 and in additional predicate K222231.

The provided text is a 510(k) clearance letter for a dental implant system. It does not contain any information about acceptance criteria or a study proving that an AI/ML device meets acceptance criteria. The "Performance Data" section discusses non-clinical testing for the dental implant itself, such as sterilization validation, shelf-life testing, and biocompatibility, as well as fatigue testing and MRI environment compatibility. This is for a physical medical device, not a software device that relies on AI/ML.

Therefore, I cannot provide the requested information as it is not present in the given document.

To reiterate, the document is about a physical dental implant system and the performance data pertains to its physical properties, sterility, and biocompatibility, not to the performance of an AI/ML algorithm.

Straumann® RidgeFit Implants ∅ 2.4 mm are indicated for oral endosteal implantation in the fully edentulous mandible and/or maxilla for the stabilization of removable dentures. The implants can be placed with immediate function when primary stability is achieved for all implants or with conventional loading if primary stability is not achieved on all implants.

• Mandibular restorations require at least 4 Straumann® RidgeFit Implants ∅ 2.4 mm.
• Maxillary restorations require at least 6 Straumann® RidgeFit Implants ∅ 2.4 mm.

The Straumann® RidgeFit Implants are tapered implants manufactured from Roxolid® (Titanium-Zirconium alloy, TiZ) with a finished SLA surface. The implant neck is machined with an Optiloc® attachment portion, which is coated in Titanium Nitride (TiN) coating, resulting in a one-piece implant system acting as a retention feature for dentures. The Straumann® RidgeFit Implants have an external diameter of 2.4 mm and are available in implant lengths 10 mm, 12 mm and 14 mm with a gingival height of 2.8 mm and implant lengths 10 mm and 12 mm for gingival heights 3.8 mm and 4.8 mm. The Straumann® RidgeFit Implants ∅ 2.4 mm are suitable for oral endosteal implantation in the upper and lower jaw of fully edentulous patients. Conventional loading is recommended if primary stability cannot be achieved immediately on all implants.

The provided FDA 510(k) clearance letter and summary for the Straumann® RidgeFit Implants contains information regarding the device's technical specifications and non-clinical testing. However, it does not include any information about acceptance criteria or a study that uses a test set with ground truth established by experts to prove the device meets these criteria.

The document focuses on demonstrating substantial equivalence to predicate devices through technical comparisons and non-clinical engineering tests (fatigue, insertion torque, biocompatibility, sterilization, packaging stability, MRI compatibility). These are performance tests on the device itself, not evaluations based on human-in-the-loop or standalone AI performance using a study with a test set and expert-established ground truth.

Therefore, I cannot provide the requested information for the following points as they are not present in the given text:

• A table of acceptance criteria and the reported device performance: The document implicitly states that passing the non-clinical tests demonstrates "substantial equivalence," but does not define explicit acceptance criteria or performance metrics directly from a comparative study with a test set and ground truth.
• Sample sized used for the test set and the data provenance: No such test set or study is described within the provided text.
• Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable as no such test set or expert ground truth establishment is described.
• Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
• If a multi reader multi case (MRMC) comparative effectiveness study was done: No MRMC study is mentioned. The clearance is for an endosseous dental implant, which is a physical device, not an AI software intended for interpretation or diagnostic assistance that would typically undergo such studies.
• If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
• The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable.
• The sample size for the training set: Not applicable.
• How the ground truth for the training set was established: Not applicable.

What the document does provide regarding testing:

The device's performance is proven through a summary of non-clinical testing, which includes:

1. Dynamic fatigue testing: Conducted according to FDA guidance (Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments) and ISO 14801 ("Dentistry — Implants — Dynamic loading test for endosseous dental implants"). This testing demonstrated the subject devices are equivalent to primary predicate and reference devices.
2. Insertion torque and Torque-to-failure test: Conducted and demonstrated substantial equivalence to the primary predicate device.
3. Biocompatibility evaluation: Referenced K211052 and K191895 for evaluation in accordance with ISO-10993-1:2018 and FDA guidance.
4. Sterilization validation: Referenced K211052 and K191895 for validation in accordance with ISO 11137-1:2006 (VDmax25 method).
5. Packaging stability and shelf-life study: Referenced K211052 and K191895 for studies in accordance with ISO 11607-1:2019, ASTM F1886, ASTM F1929, and ASTM F88.
6. MRI simulations: Conducted to demonstrate that the devices are MR Conditional.

These tests are primarily physical and chemical performance assessments of the implant materials and design, aimed at establishing safety and effectiveness, and equivalence to existing cleared devices, not at evaluating an AI's diagnostic performance against human experts.

To enhance the osseointegration with the alveolar bone, this titanium dental implant is treated with SLA (Sandblasted with Large-grit and Acid-etching). As a dental implant which is placed into alveolar bone to support dental prostheses such as artificial teeth used to rehabilitate a patient's masticatory function, the product is used as a substructure implanted into the human body.

An endosseous dental implant is a device made of a material as Pure Titanium (Conforming to ASTM F67) which will be placed in the alveolar bone to replace the function of the missing tooth. The SD TL Implant System consists of dental implants, abutments for use in one or two-stage dental implant placement and restorations.

The implant-abutment connection is tight and precise fitting with non-submerged external connection and with submerged internal connection. The surface of the fixture is treated with SLA (Sandblasted with Large-grit and Acid-etching). It is only part to be implanted into bone, and to provide connection of prosthetic devices or other components of a dental implant set with human body (mandibular or maxillary bone).

The dimension ranges of the subject device are below:

1. SD Tissue Level Fixture: Ø 3.7, 4.2, 4.6, 5.0 (D) x 7.0, 8.5, 10.0, 11.5, 13.0 mm (L)
2. SD Bone Level Fixture: Ø 6.48 (D) x 7.0, 8.5, 10.0, 11.5 mm (L)

2. Abutment
   The abutment is made of Ti-6Al-4V Eli (Conforming to ASTM F136) to be used in fabricating patient-specific abutments. The subject devices are indicated for cemented or screw-and cement retained prosthesis (SCRP) restorations. Each patient-specific abutment is individually prescribed by the clinician. The Multi Angled cylinders come in engaging and non-engaging types.

1. Multi Angled Cylinder: Ø 5.5 (D) x 9.5, 10.5 mm
2. Multi Digital Cylinder: Ø 5.5 (D) x 6.5, 7.5, 8.5, 9.5 mm
3. Multi Ti Cylinder: Ø 4.8 (D) x 4.5 mm, Ø 5.5 (D) x 8.0, 9.0 mm
4. Multi Healing Cap: Ø 4.8, 5.7 (D) x 4.35, 5.85, 7.35 mm
5. Healing Abutment: Ø 3.5, 3.67, 4.2, 5.2, 6.2, 7.5, 8.5 (D) x 6.9 ~ 13.3mm
6. Temporary Abutment: Ø 3.7, 4.0 (D) x 10.4, 10.45, 12.4, 12.45 mm

Tolerance of dimension shall be within ± 1% range.

Multi Digital Cylinder and Multi Ti Cylinder are used as part of a two-piece abutment, where the base is premanufactured from titanium alloy (Ti-6Al-4V Eli) and the top half is a CAD/CAM zirconia superstructure, milled at a validated milling center. These pieces are cemented together to form the final abutment.

The Titanium Base abutment is composed of two-piece abutment that is a titanium base at the bottom and a zirconia superstructure (CAD/CAM patient specific superstructure) at the top. The zirconia superstructure is straight only and is not to be designed to provide an angle or divergence correction.
For the Multi Digital Cylinder and Multi Ti Cylinder the design parameters for the CAD/CAM zirconia superstructure are:

• Minimum wall thickness – 0.5 mm;
• Minimum post height for single-unit restorations – 4.5 mm;
• Maximum gingival height – 5.0 mm;
• Minimum gingival height – 0.5 mm;
• Angulation - 0°
  *The post height is defined as measured above the gingival height of the final patient-matched design.

The digital workflow requires the use of the following equipment:

• Restorative Material: Non-Sterile Zirconia Block (K190112)
• Dental Cement: U-Cem Premium & MAZIC Cem (K193260)

The SD TL Implant System is compatible with the SD Bone Level Fixtures and NB Implant Systems. (as the below table).

The provided FDA 510(k) Clearance Letter for the "SD TL Implant System" does not contain information about acceptance criteria or a study proving the device meets those criteria in the context typically seen for Artificial Intelligence (AI) or software as a medical device (SaMD) products.

This document is for a physical medical device (dental implants and associated components), specifically an endosseous dental implant (Product Code: DZE, NHA; Regulation Number: 21 CFR 872.3640; Regulatory Class: Class II).

The "performance data" section in this document describes:

• Biocompatibility testing (ISO 10993-5, ISO 10993-12) to ensure the materials are safe for use in the human body.
• Sterilization validation (ISO 11137-1, 11137-2, ANSI/AAMI ST79, ISO 17665-1, -2, ISO 11737-1,-2, ISO 11138-1, AAMI / ANSI ST72:2011/(R)2016) to ensure the device is sterile.
• Shelf-life testing (ASTM F1980) to confirm stability over time.
• Mechanical performance testing (ISO 14801) for static compression and compression fatigue, which are standard tests for the structural integrity of dental implants.
• Scanning electron microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDS) for surface characteristics.
• MR environment condition review to assess safety in MRI environments.

These tests are standard for a physical implantable device to demonstrate substantial equivalence to a predicate device. They are not related to AI/software performance criteria (like accuracy, sensitivity, specificity, AUC) or human reader study designs (like MRMC studies, ground truth establishment by experts, adjudication methods).

Therefore, I cannot populate the requested table or answer the questions related to AI/software performance, ground truth, expert consensus, or MRMC studies, as this information is not present in the provided document.

The document explicitly states: "Non-clinical testing data submitted, referenced or relied on in this submission support demonstrating substantial equivalence." and "The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the primary predicate." This refers to the physical and material properties, not AI algorithm performance.

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.

Non-Clinical Performance Data (Serving as "Study" for Substantial Equivalence):

1. Worst-Case MRI Review:

   • Method: Scientific rationale and published literature (T.O. Woods, J.G. Delfino, and S. Rajan, "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices," Journal of Testing and Evaluation Volume 49, No. 2 (March/April 2021): 783–795).
   • Scope: Evaluated all compatible implant bodies, abutments, and fixation screws and their material composition.
   • Parameters: Magnetically induced displacement force and torque, per FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment."

The Hexim Implant - The HEXIM Implant System is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations. The HEXIM Implant System is for two stage surgical procedures. It is intended for delayed loading.

Samwon General Abutments - Couple Abutments are intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures. Healing abutments are used to make a natural soft tissue shape before setting up prosthetics and removing cover screw after osseointegration. Cover Screws are used to protect the internal portion of the implant, preventing soft tissue growth into the implant, facilitating provisional restorations when necessary, and enabling the transition to final restoration components once osseointegration is complete.

The HEXIM Implant with Samwon General Abutments is a Root-form Endosseous Dental Implant and Endosseous Dental Abutment system designed for use in dental implant surgery. These devices have special controls as described by the document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments – Class II Special Controls Guidance for Industry and FDA Staff.

The HEXIM Implant is a threaded root-form endosseous dental implant with an internal hexagon connection. The HEXIM implants are surgically inserted into the upper and/or lower jawbone to provide a stable foundation for restorations. Geometrically, the implant is screw type. It has external self-tapping threads with chip pocket vertical flutes to facilitate implantation. The HEXIM implant also includes a cavity which extends through the bottom of the implant and connects to 5 channels running perpendicular to the implant body long axis to aid in intra bone fixation. The bottom cavity is not directly interconnected to the internal hex connection nor to the internal threading feature used to fix abutments to the implant.

The Samwon General Abutments are connected to the implant through the implant's internally threaded hole and an internal hex connection. Samwon General Abutments come in several types: Cover Screw, Healing Abutment, Hex type Couple Abutment, and Abutment Screw. Cover Screws are used to protect the internal portion of the implant, preventing soft tissue growth into the implant, facilitating provisional restorations when necessary, and enabling the transition to final restoration components once osseointegration is complete. Healing abutments are used after osseointegration, once the cover screw is removed, to make a natural soft tissue shape before setting up prosthetics. The Hex-type Couple Abutment is designed to mate with the internal hex cavity of the endosseous implant and is fixed to the implant via an abutment screw. The Hex-type Couple Abutment is a transgingival component, which serves as the support for the artificial tooth or other prosthetic.

The provided FDA 510(k) clearance letter for the HEXIM Implant and Samwon General Abutments is for a medical device that includes physical implants and abutments, not an AI or software-based medical device. Therefore, the information typically associated with acceptance criteria and a study proving an AI device meets those criteria (such as sample size for test sets, data provenance, expert adjudication, MRMC studies, standalone performance, ground truth establishment, and training set details) is not applicable to this document.

This 510(k) summary focuses on demonstrating substantial equivalence to predicate devices through comparisons of:

• Intended Use and Indications for Use
• Technological Characteristics (material, design, dimensions, sterilization, surface treatment, connection type, principle of operation)
• Performance Testing (bench testing, biocompatibility, sterilization validation)

The "study" that proves the device meets acceptance criteria in this context is the non-clinical performance testing and the demonstration of substantial equivalence to legally marketed predicate devices, rather than a clinical trial or AI model validation study.

Here's a breakdown of the relevant information provided in the document concerning how the device meets its "acceptance criteria" (understood as demonstrating substantial equivalence and safety/effectiveness):

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

The document does not present explicit "acceptance criteria" in a tabulated form with specific numerical targets typical for AI model performance (e.g., AUC > X, Sensitivity > Y). Instead, the "acceptance criteria" are implicitly met by demonstrating substantial equivalence to predicate devices and adherence to relevant industry standards and guidance documents. The "reported device performance" is demonstrated through various tests and comparisons:

• Surface Treatment: SLA (Similar to predicate, same as reference; justified differences do not affect substantial equivalence).
• Sterilization: Gamma irradiation (Same as reference, predicate not specified).
• Connection Type: Internal Hex (Same as both predicate and reference).
• Fixture Body Diameter/Length: Differ slightly but fall within predicate/reference ranges or justified as not affecting safety/efficacy.
• Bottom Cavity: Presence/absence compared and justification provided. |
  | Technological Characteristics Equivalence (Samwon General Abutments) | - Material: Ti-6Al-4V ELI of ASTM F136 (Same as predicate/reference).
• Surface Treatment: None (Same as predicate; justified difference from reference).
• Sterilization: End User (Steam) (Same as predicate/reference where specified).
• Connection Type: Threaded/Internal Hex (Same or similar, justified).
• Dimensions (Diameter, Length, G/H, Post Height): Differ but fall within predicate/reference ranges or justified as not affecting safety/efficacy; mechanical testing confirms suitability. |
  | Biocompatibility | Tested in accordance with ISO 10993 series for various biological endpoints (cytotoxicity, irritation, sensitization, systemic toxicity, implantation effects, chemical characterization). Results implicitly met acceptance criteria as they support substantial equivalence. |
  | Sterilization Validation | For HEXIM Implants (sterile): ISO 11137 series.
  For Abutments (non-sterile, end-user steam): ANSI/AAMI ST79:2017 & ISO 17665 series. LAL bacterial endotoxin testing also performed. Results implicitly met acceptance criteria. |
  | Shelf-Life | Established via accelerated aging per ASTM F1980-2021 at 5 years for HEXIM Implants. |
  | Mechanical Performance (Bench Testing) | - Fatigue Testing: Performed per ISO 14801:2007 using worst-case geometries. Results met criteria.
• Implant-to-Abutment Compatibility: Determined through mechanical testing. Results implicitly met criteria.
• Surface Analysis (SLA): Chemical and visual analysis performed to ensure no blasting particles/chemicals remain. Results implicitly met criteria. |
  | MRI Safety | Non-clinical worst-case MRI review performed using scientific rationale and published literature, addressing magnetically induced displacement force and torque. Justified as safe. |

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

This information is not applicable as this is a medical device clearance for physical implants and abutments, not an AI/software device. The "test set" here refers to physical samples used in bench testing.

• Sample Size: Not explicitly stated for each bench test (e.g., number of implants for fatigue testing). The tests were performed on "representative final manufactured samples."
• Data Provenance: Not applicable. Tests are conducted in a lab environment (e.g., ISO-certified labs for mechanical and biocompatibility testing).
• Retrospective or Prospective: Not applicable. Bench testing is a controlled, experimental process, not typically classified as retrospective or prospective clinical data.

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 information is not applicable. Ground truth establishment by experts pertains to diagnostic AI models. For physical implants, "ground truth" is established through physical and chemical measurements against engineering specifications and international standards, and results are interpreted by engineers and scientists.

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

This information is not applicable. Adjudication methods are relevant for human interpretation of data, typically in diagnostic studies for AI. For bench testing, results are objective measurements against defined 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 information is not applicable. MRMC studies are for evaluating diagnostic performance, particularly with AI assistance. This submission is for physical dental implants and abutments.

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

This information is not applicable. Standalone performance refers to AI algorithm performance. This is a physical device.

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

For this device, the "ground truth" for demonstrating safety and effectiveness includes:

• Engineering Specifications: Design drawings, material specifications (e.g., ASTM F67, ASTM F136).
• International Standards: ISO 14801 (fatigue), ISO 10993 series (biocompatibility), ISO 11137 / ANSI/AAMI ST79 / ISO 17665 series (sterilization).
• FDA Guidance Documents: "Class II Special Controls Guidance Document Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments" and "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment."
• Pre-market Review Precedents (Predicate Devices): The performance and safety profile of the legally marketed predicate devices (K111889, K190641, K221866, K222792) serve as the established "ground truth" for substantial equivalence.

8. The sample size for the training set

This information is not applicable. There is no "training set" for physical medical devices in the context of AI/machine learning.

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

This information is not applicable. There is no "training set" for physical medical devices that requires ground truth establishment in the AI sense. The design and manufacturing processes follow established engineering principles and quality systems (21 CFR Part 820), which ensure the product meets its intended specifications.

The AOT Straight and AOT Angled Abutments are compatible with the Base and Temporary Abutments included in this submission, as well as those previously cleared under K231874.

The provided FDA 510(k) clearance letter for URIS Long Implant & Abutments does not contain information about acceptance criteria and study proving device performance as typically expected for AI/ML-driven medical devices. This submission is for a traditional dental implant system, and the clearance is based on substantial equivalence to predicate devices through non-clinical testing, primarily focusing on mechanical, material, and biocompatibility properties.

Therefore, many of the requested elements regarding acceptance criteria for device performance (e.g., sensitivity, specificity, AUC), study design (sample size, data provenance, ground truth establishment, expert adjudication), and AI/ML-specific study types (MRMC, standalone performance) are not applicable to this submission.

However, I can extract the information relevant to the type of device and submission, specifically the non-clinical acceptance criteria and the tests performed to meet them.

Acceptance Criteria and Supporting Study for URIS Long Implant & Abutments

As this FDA 510(k) pertains to a traditional dental implant and abutment system (URIS Long Implant & Abutments, K243255), and not an AI/ML device, the acceptance criteria and study details are focused on non-clinical performance, primarily demonstrating mechanical integrity, material compatibility, and safety through established engineering and biological standards, rather than diagnostic accuracy metrics.

The clearance is largely based on demonstrating substantial equivalence to previously cleared predicate devices through a series of non-clinical tests.

1. Table of Acceptance Criteria and Reported Device Performance

Given the nature of this device (dental implants), the "performance" is demonstrated through engineering and biocompatibility testing rather than diagnostic accuracy. The acceptance criteria are implicitly meeting the requirements of the cited ISO and USP standards. The document doesn't provide specific quantitative "pass/fail" values for each test, but rather states that the device "met the criteria of the standards."

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

• Sample Size: Not explicitly stated in terms of a "test set" as one would expect for an AI/ML device. The "sample size" would refer to the number of physical dental implants/abutments subjected to each non-clinical test (e.g., number of units for fatigue testing, number of samples for biocompatibility). These numbers are not detailed in the summary but would be standard for regulatory testing required by the ISO/ASTM standards cited (e.g., minimum of 5-10 samples for fatigue per condition).
• Data Provenance: Not applicable in the context of patient data for diagnostic accuracy. The "data" originated from laboratory testing of the manufactured dental implants and abutments.

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

• Not Applicable: This clearance is based on non-clinical engineering and biological safety tests (e.g., fatigue strength, sterility, biocompatibility), not on the interpretation of medical images or patient data requiring expert consensus or ground truth establishment by clinical experts like radiologists.

4. Adjudication Method for the Test Set

• Not Applicable: As there is no human interpretation of data for diagnostic purposes, there's no need for an adjudication process. Test results are objective measurements (e.g., force at failure, sterility present/absent).

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• Not Performed / Not Applicable: MRMC studies are specific to evaluating diagnostic devices, particularly those involving human readers and AI assistance. This device is a physical dental implant, not a diagnostic AI tool.

6. Standalone (Algorithm Only) Performance Study

• Not Performed / Not Applicable: This is a physical medical device, not a software algorithm.

7. Type of Ground Truth Used

• Engineering/Material Standards and Biological Safety Standards: The "ground truth" for this device's performance is established by the specified ISO and ASTM standards (e.g., ISO 14801 for fatigue testing, ISO 10993-1 for biocompatibility). These standards define acceptable performance limits for mechanical properties and biological responses.

8. Sample Size for the Training Set

• Not Applicable: This device is not an AI/ML algorithm that requires a training set. Its design and manufacturing are based on established engineering principles and materials science.

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

• Not Applicable: As there is no training set for an AI/ML algorithm, this question is not relevant.

The T3® Pro Implants are intended for surgical placement in the upper or lower jaw to provide a means for prosthetic attachment in single tooth restorations and in partially or fully edentulous spans with multiple single teeth utilizing delayed loading, or with a terminal or intermediary abutment for fixed or removable bridgework, and to retain overdentures.

The T3® Pro Implants may also utilize immediate loading for these indications. The T3® Pro Implants are intended for immediate function on single tooth and/or multiple tooth applications when good primary stability is achieved, with appropriate occlusal loading, in order to restore chewing function.

The T3® Pro Implants with the new ZimVie Implant Packaging System. The material and design of the subject device is identical to the primary predicate device T3® Pro Implants cleared in K213672.

The ZimVie Implant Packaging System configuration, similarly to the primary predicate device, consists of a titanium sleeve that is inserted into a polypropylene inner tray, covered with a Tyvek lid and heat-sealed. This assembly is then placed in a heat-sealed outer tray, covered with a Tyvek® lid. The outer tray is placed inside a cardboard box, and gamma sterilized. The new ZimVie Packaging System has been standardized to align the packaging across all ZimVie implant families. The subject device in the new ZimVie Packaging System has a shelf-life of two (2) years.

The provided FDA 510(k) clearance letter and associated documentation for the "T3 Pro Implants- ZimVie Packaging System" (K251660) do not describe acceptance criteria or a study proving the device meets those criteria in the context of an AI/human reader performance study.

Instead, this submission is for a medical device (endosseous dental implant) and its new packaging system. The "performance data" section explicitly states that no clinical data was included in the submission for the substantial equivalence determination. The focus of the provided document is to demonstrate equivalence to a previously cleared predicate device for the dental implant itself, with the primary change being the packaging system.

Therefore, I cannot fulfill your request to create a table of acceptance criteria and reported device performance related to an AI-assisted or standalone AI system, nor can I provide details on sample size, expert adjudication, MRMC studies, or ground truth establishment, as these concepts are not discussed or relevant to the provided documentation for this specific 510(k) clearance.

The information provided describes non-clinical performance data related to the physical device and its packaging:

• Sterilization validation: Gamma irradiation sterilization to a sterility assurance level of 10^-6 according to ISO 13004 and ISO 11137.
• Aging studies: Demonstrating a shelf life of two (2) years for the implants, with packaging sterile barrier testing per ASTM F1980.
• Packaging studies: Simulated distribution and environmental conditioning per ISTA 3A and ASTM D4169.
• Biological evaluation: Leveraged from the primary predicate device, demonstrating no increased risks regarding biocompatibility. The material is Commercially Pure Titanium conforming to ASTM F67.
• MR Safety testing: Conducted according to ASTM F2503-13 on the primary predicate device (identical to the subject device) for MR Conditional determination.
• Bacterial Endotoxin Testing: Routinely performed using LAL assay in accordance with ISO 11737-3.

The acceptance criteria for this submission would primarily revolve around demonstrating that the new packaging system maintains the sterility, integrity, and safety of the dental implant for its stated shelf life, and that the dental implant itself remains identical to the previously cleared predicate device in all other aspects (materials, design, intended use, operating principle).

In summary, your request pertains to an AI/Software as a Medical Device (SaMD) study, while the provided document describes the 510(k) clearance process for a physical dental implant device and its new packaging.
