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 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.

Indications for use Bilimplant® dental implants are indicated for the functional and esthetic oral rehabilitation of the upper or lower jaw of edentulous or partially edentulous patients. They can be used for immediate, early or late implantation following the extraction or loss of natural teeth. The implants can be placed with immediate function for single-tooth and/or multiple tooth applications when good primary stability is achieved and with appropriate occlusal loading to restore chewing function.

Bilimplant Abutments and Prosthetic parts are intended for use with Implants in the maxillary and / or mandibular arches to provide support for crowns or bridges for edentulous or partially edentulous patients.

The Bilimplant® dental implants and abutments, which are models within the Proimtech Implant and Abutment system, are intended for oral implantation to provide a support structure for connected prosthetic devices.

Bone Level Implant: Thanks to its design features, it is placed completely at the bone level. It is produced to be applied in different bone types and different regions (anterior and posterior) in the lower and upper jaw. Since it is at the bone level, it can be used for more aesthetic results, especially in the front areas of the jaws (in the areas on the smile line).

Tissue Level Implant: The Tissue Level Implant has a 2.3 mm machined collar. It can be used in posterior applications in the upper and lower jaw where there are no aesthetic concerns, in different bone types and especially in cases with high gingival amount in order to facilitate prosthetic stages.

Straight Abutments: It is the superstructure part that supports fixed partial dentures manufacture on a straight implant. It is used in single member or bridge cemented restorations. Cement retained abutments have a different gingival height of 1-5 mm, diameters of 3.5, 4.5, 6 mm depending on the platform diameters.

Healing Caps: Following the second surgery of the gingiva in two-stage surgical procedures, and after the placement of the implant in single-stage surgeries, it is screwed into the implant body and protects the internal structure of the implant. It is not used to support a prosthetic superstructure. It is used for transgingival healing and shaping of soft tissue during the healing process of soft tissue. There are two different designs for healing caps in dental implant systems. These are manufactured to be compatible with tissue level and bone level implants.

Abutment Screws: Connects and fixes the abutment and implant body.

This is a 510(k) premarket notification for a medical device family consisting of Proimtech Dental Body Implants, Abutments, Healing Caps, and Abutment Screws. The provided document is an FDA clearance letter and a 510(k) Summary, which details the device's characteristics and its substantial equivalence to previously cleared devices.

The document does not describe a study proving the device meets specific acceptance criteria in terms of performance metrics like accuracy, sensitivity, or specificity, as it is a medical device clearance for physical devices, not a diagnostic or AI-powered device.

Therefore, I cannot provide information on acceptance criteria and a study proving the device meets them in the context of diagnostic performance. The studies mentioned are related to material properties, sterilization, biocompatibility, and packaging, which are standard for dental implants.

However, I can extract the information provided regarding the testing and characterization of the device components, which serve as evidence for their safety and effectiveness in achieving substantial equivalence.

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

Since this is a physical medical device (dental implants and associated components) and not an AI/diagnostic device, the concept of "acceptance criteria" and "reported device performance" typically refers to engineering performance (e.g., strength, durability, biocompatibility) rather than diagnostic metrics. The document describes several tests conducted to ensure the device's fundamental characteristics are met:

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

The document does not specify sample sizes for these tests (e.g., how many implants were tested for sterilization or biocompatibility). This level of detail is typically found in the full test reports, not the 510(k) summary.

• Data provenance: The testing was conducted as part of the regulatory submission process for a manufacturer in Turkey (Proimtech Saglik Urunleri Anonim Sirketi, Istanbul, Turkey). The studies are non-clinical (laboratory-based) as explicitly stated: "No clinical data were included in this submission." The testing would be considered prospective in the sense that it was performed specifically for this submission.

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

This question is not applicable to the type of device and studies described. "Ground truth" and "experts" in this context typically refer to diagnostic interpretation in AI or clinical studies. For physical device testing (material, sterilization, biocompatibility), the "ground truth" is established by adherence to international standards (e.g., ISO, ASTM, USP) and the results are interpreted by qualified laboratory personnel, not by a panel of medical experts establishing a "ground truth" for a diagnosis.

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

This is not applicable for non-clinical, laboratory-based testing of physical medical device properties. Adjudication methods are typically used in clinical trials or diagnostic performance studies to resolve discrepancies in expert opinions or outcomes.

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. MRMC studies are used to evaluate the interpretive performance of readers (e.g., radiologists) with and without assistance from an AI device for diagnostic tasks. The Proimtech Dental Body Implant system is a physical dental implant and prosthetic components, not a diagnostic AI system.

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 medical implant, not an algorithm or AI.

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

As explained in point 3, the concept of "ground truth" in the context of diagnostic devices is not applicable here. For the non-clinical tests conducted, the "ground truth" is defined by the objective measurement criteria and specifications outlined in the referenced international standards (e.g., ISO 11137 for sterilization, ISO 10993 for biocompatibility) and scientific analytical methods (e.g., SEM/EDS for surface characterization). Compliance with these standards is the "ground truth" for the device's physical and biological properties.

8. The sample size for the training set

This is not applicable. This device is a physical medical implant, not an AI or machine learning model that requires a training set.

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

This is not applicable, as there is no training set for a machine learning model.

The 510(k) submission for this dental abutment focuses on establishing substantial equivalence based on:

• Design and Material: The subject device components are identical in design, material (Ti-6Al-4V alloy, DLC coating), and technological characteristics to previously cleared devices.
• Manufacturing: The manufacturing process is consistent with previously cleared devices.
• Biocompatibility: Referenced from previous K-clearances.
• Sterilization: The main change in this submission is expanding the system to provide products sterile to the end-user via gamma irradiation, which was validated by referencing a previous K-clearance (K212538).
• MR Environment Testing: Non-clinical analysis was performed to evaluate the subject devices in the MR environment, referencing published literature and FDA guidance.
• Shelf Life Testing: Referenced from a previous K-clearance (K212538) for samples after accelerated aging.

Therefore, I cannot fulfill your request to describe the acceptance criteria and a study proving an AI/ML device meets them based on the provided text, as this document is not about an AI/ML medical device.

1. Table of acceptance criteria and reported device performance:

The document primarily focuses on demonstrating substantial equivalence to predicate devices rather than setting explicit quantifiable acceptance criteria as a standalone device. However, the performance testing section details the types of tests conducted and implicitly states that the results demonstrated equivalence.

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

• Sterilization Validation: The validation method used was the over kill bioburden method. While details on the number of samples for bioburden testing are not specified, it would typically involve a statistically significant number of samples to establish the bioburden and then validate the sterilization process. Data provenance is not specified.
• Pyrogenicity: The number of devices tested for LAL Endotoxin Analysis is not specified. Data provenance is not specified.
• Bench Testing (Dynamic Fatigue, Static Strength, Insertion Torque): The sample sizes for these tests are not explicitly stated in the document. Data provenance is not specified.
• Clinical Data: No device-specific clinical data has been submitted.

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 submission relies on substantial equivalence and bench testing, not clinical studies requiring expert ground truth for a test set.

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

Not applicable, as no clinical test set requiring adjudication by experts was used.

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 a dental implant, not an AI-assisted diagnostic tool.

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 Aurum™ Abutment or Pre-milled Blank are to be sent to a Terrats Medical validated milling center for manufacture.

DESS Dental Smart Solutions subject devices include four abutment design types (Aurum Base, Pre-milled Blank, CoCr Pre-milled Blank, CoCr Abutment) and one screw type (Aurum Base Screw). Abutments are provided in ten abutment connections compatible with eleven implant platform diameters range from 3.3 mm to 6.5 mm. Corresponding implant body diameters range from 3.25 mm to 6.0 mm. All abutments are provided non-sterile.

The document describes the DESS Dental Smart Solutions, which are dental implant abutments. The submission aims to demonstrate substantial equivalence to previously cleared predicate devices.

Here's an analysis of the provided information regarding acceptance criteria and studies:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state quantitative acceptance criteria in a typical tabular format with specific numerical targets. Instead, it relies on demonstrating equivalence to predicate devices through various performance tests and comparisons. The "acceptance criteria" are implied by the successful completion of these tests and the determination that the device is "substantially equivalent" to already marketed devices.

However, some design parameters are mentioned as remaining the same or being comparable to the predicate devices, which can be seen as implicit performance criteria:

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

The document states: "Non-clinical testing data submitted to demonstrate substantial equivalence included: sterilization... biological evaluation... and compatibility analysis by reference to K170588."

• The report does not specify sample sizes for the sterilization or biocompatibility tests.
• The data provenance is implied to be from the manufacturer's (Terrats Medical SL) internal testing as part of their submission for regulatory clearance. It's not explicitly stated whether the data is retrospective or prospective, or the country of origin of the raw data, beyond the manufacturer being from Spain. The "compatibility analysis by reference" means using existing data/information from the predicate device (K170588).

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

This type of information – number and qualifications of experts for ground truth – is typically relevant for studies involving subjective assessments, like image interpretation in AI/ML medical devices. This document is for a physical dental implant abutment, and the tests performed are objective, non-clinical tests (sterilization, biocompatibility, mechanical properties based on design parameters). Therefore, this information is not applicable and not provided in the submission.

4. Adjudication Method for the Test Set

As the tests are objective non-clinical tests, an adjudication method for a "test set" (in the context of expert review) is not applicable and not mentioned. The results of the non-clinical tests would either meet or not meet the specified standards (e.g., SAL, non-cytotoxicity).

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No MRMC comparative effectiveness study was done. This type of study is specifically relevant for AI/ML-driven diagnostic or interpretative devices involving human readers. The device described here is a physical dental implant abutment, not an AI/ML diagnostic tool.

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

No standalone algorithm performance study was done. This is not an AI/ML device. The "CAD/CAM process" mentioned refers to computer-aided design and manufacturing for custom abutments, which is a manufacturing process, not an analytical algorithm for diagnosis or interpretation.

7. The Type of Ground Truth Used

For the non-clinical tests conducted:

• Sterilization: The ground truth is the scientific standard for sterility, defined as a Sterility Assurance Level (SAL) of $10^{-6}$ based on ISO 17665-1 and ISO 17665-2.
• Biocompatibility: The ground truth is the absence of cytotoxicity, determined by adherence to ISO 10993-1 and ISO 10993-5.
• Design Parameters/Mechanical Equivalence: The "ground truth" for design parameters (e.g., wall thickness, post height) is derived from engineering specifications and comparison to the proven safety and effectiveness of the legally marketed predicate devices (K170588 and other reference devices). The ultimate ground truth effectively is that the device performs equivalently to previously approved devices.

8. The Sample Size for the Training Set

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

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

Not applicable. As this is not an AI/ML device, there is no training set or associated ground truth establishment process in that context.

The provided text describes a 510(k) premarket notification for a medical device, the LOCATOR® F-Tx Attachment System. It focuses on demonstrating substantial equivalence to pre-existing predicate devices, rather than presenting a study design with specific acceptance criteria and detailed performance data often seen for novel AI/ML devices. As such, many of the requested points regarding acceptance criteria, study types (MRMC, standalone), sample sizes for test/training sets, expert qualifications, and ground truth establishment are not applicable or cannot be extracted from this document, as it is not a performance study report for an AI/ML device.

This document outlines the device's intended use, design, materials, and provides a comparison to legally marketed predicate devices to establish substantial equivalence. The "Performance Data" section primarily details the non-clinical testing performed to meet various ISO standards related to sterilization, biocompatibility, and mechanical testing, which are typical for dental implant components.

Here's an attempt to address the request based only on the available information, noting where information is absent:

Acceptance Criteria and Device Performance for LOCATOR® F-Tx Attachment System

Based on the provided 510(k) summary, the "acceptance criteria" are primarily demonstrated through substantial equivalence to predicate devices and adherence to relevant non-clinical performance standards. The performance data presented focuses on material properties, sterilization, biocompatibility, and mechanical retention, rather than performance metrics for an AI/ML system.

Medentika TiBase CAD/CAM Abutments are intended for use with dental implants as a support for single or multiple tooth prostheses in the maxilla or mandible of a partially or fully edentulous patient.

Medentika PreFace CAD/CAM Abutments are intended for use with dental implants as a support for single or multiple tooth prostheses in the maxilla or mandible of a partially or fully edentulous patient.

The subject device includes two CAD/CAM abutment designs, the Medentika TiBase and the Medentika PreFace. The TiBase is a two-piece abutment used as a base when fabricating a zirconia superstructure and the PreFace is an abutment used in fabricating a full patient-specific abutment in titanium alloy. Both abutment designs are provided non-sterile and are intended to be sterilized by the clinician. Medentika Preface Abutment is available in diameters 3.0 mm to 7.0 mm. Medentika TiBase Abutment is available in diameters 3.25 mm to 7.0 mm. The specific diameters for each Series coordinate with the compatible implant systems and sizes listed below.

TiBase is available in two post designs. TiBase Generation 1 has a conically shaped post that is 4.0 mm high and TiBase Generation 2 has a parallel walled post shape that is 5.5 mm high. PreFace is available in one cylinder height of 20 mm. The maximum angle for abutments fabricated using TiBase or PreFace is 30°, the maximum gingival height is 6 mm and the minimum post height is 4 mm.

Medentika CAD/CAM Abutments are compatible with eleven dental implant systems. Each Medentika abutment series has a precision implant/abutment interface corresponding to the implant system predicate for that series.

The provided document is a 510(k) premarket notification for Medentika CAD/CAM Abutments, asserting substantial equivalence to legally marketed predicate devices. It does not describe a study involving an AI/ML powered device, nor does it detail acceptance criteria related to such a device's performance. Instead, it focuses on non-clinical testing to demonstrate safety and effectiveness for a dental abutment. Therefore, I cannot extract the requested information regarding acceptance criteria, study design for AI/ML performance, ground truth establishment, or human-in-the-loop studies from this document.

The "Performance Data" section (Page 6/7) explicitly states the types of non-clinical testing conducted:

• Engineering analysis and dimensional analysis: To determine compatibility with original manufacturers' components.
• Static and dynamic compression-bending testing: According to ISO 14801 (Dentistry – Implants – Dynamic fatigue test for endosseous dental implants).
• Sterilization testing: According to ISO 17665-1 and ISO 17665-2 to demonstrate an SAL of 10^-6.
• Biocompatibility testing: For cytotoxicity according to ISO 10993-5.

The acceptance criteria would be the successful completion of these tests in accordance with the specified ISO standards and demonstrating compatibility and performance comparable to the predicate devices. However, the document does not list the quantitative acceptance criteria or the specific numerical results obtained for each test (e.g., specific fatigue life, or precise dimensional tolerances met).

In summary, the document does not contain the information required to answer the prompt as it pertains to AI/ML device performance. The device is a physical medical device (dental abutments), and the review is for substantial equivalence based on physical and mechanical properties, not an AI/ML algorithm.
