STERI-OSS Implant System is for single stage surgical procedures. This system is intended for delayed loading.
STERI-OSS Implant System, Fixture is a medical device made of titanium that is inserted into the maxillary or mandibular alveolar bone to support prosthesis such as artificial teeth for the patient's recovery of masticatory function.
STERI-OSS Implant System. Abutment is inserted to support prosthesis such as artificial teeth, and is a medical device made of titanium alloy. It connects artificial teeth with a fixture implanted in the maxillary or mandibular alveolar bone where teeth are lost.
The provided document is a 510(k) summary for the STERI-OSS Implant System, which is a dental implant system. This document focuses on demonstrating substantial equivalence to predicate devices rather than providing a study where the device meets pre-defined acceptance criteria for performance in a clinical setting. For medical devices undergoing 510(k) clearance, the primary goal is to show that the new device is as safe and effective as a legally marketed predicate device, not necessarily to meet specific novel performance acceptance criteria through clinical studies.
Therefore, the requested information elements such as "acceptance criteria and the reported device performance," "sample sizes used for the test set," "number of experts used to establish ground truth," "adjudication method," "MRMC comparative effectiveness study," "standalone performance," "type of ground truth," "sample size for the training set," and "how ground truth for the training set was established" are typically not applicable in the context of a 510(k) substantial equivalence submission for a device like a dental implant. These elements are more commonly associated with clinical trials or performance studies for novel devices or software with AI/ML components requiring new clinical evidence.
The document describes non-clinical testing to demonstrate that the differences between the subject device and predicate devices do not affect substantial equivalence.
Here's a breakdown of the available and non-applicable information based on your request:

The Osteon Precision Milled Suprastructures (also referred to as superstructures) are metallic dental restorative devices that are intended to be attached by screw retention to dental implant abutments to aid in the treatment of partial and totally edentulous patients for the purpose of restoring chewing function. These suprastructures attach to dental implant abutments using the prosthetic screws from the original equipment manufacturers (OEM) and are used to support the final multi-unit restoration.
The Osteon Precision Milled Suprastructure is designed for an individual patient from scans of the patient's dental impression. The suprastructure is manufactured with the aid of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) technology. All CAD/CAM fabrication is performed by Osteon Medical.
Osteon Precision Milled Suprastructures facilitate the attachment of both removable and fixed dental prosthesis and hence are categorized as Type A and Type B.
- Type A: Intended to act as a supporting structure to facilitate the attachment of a removable dental prosthesis and include Primary Bar and Nexus Removable Bar.
- . Type B: Intended to act as a supporting structure to facilitate the attachment of a fixed dental prosthesis and include Melbourne Bar and Nexus Fixed Bar (including Nexus Hybrid, Nexus Bridge, Micro Nexus, and Nexus Wraparound).

2. Sample size used for the test set and the data provenance
The submission is a 510(k) for an expansion of an existing device (K221019). The "study" proving the device meets acceptance criteria primarily relies on non-clinical data and demonstration of substantial equivalence to predicate devices.
- Test set/Sample size: The document does not describe a "test set" in the traditional sense of a clinical or imaging study with a defined sample size for statistical analysis. Instead, it relies on:
- Reverse engineering analysis of OEM abutments and OEM abutment screws: This was done to confirm compatibility. The sample size for this analysis is not explicitly stated but would involve the specific OEM abutments listed for compatibility with the subject device.
- Fatigue testing: The document states, "Fatigue testing was not performed since the Subject devices are abutment-borne and are not intended to compensate for angulation in excess of the maximum angulation of OEM angled abutments..." This indicates that engineering analysis and design specifications, rather than physical fatigue testing, were used to demonstrate performance in this regard.
- Data provenance: Not directly applicable as there isn't a "test set" from patients. The data relies on engineering analysis, existing predicate device data, and compliance with standards.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. This is not a study requiring expert readers to establish ground truth. Substantial equivalence claims are based on engineering, material, and design comparisons to legally marketed devices.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. There is no "test set" or diagnostic performance study that would require an adjudication method.
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 physical dental suprastructure, not an AI-powered diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
Not applicable. This device is a physical dental suprastructure, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" equivalent for this submission is the established safety and effectiveness of the primary predicate device (K221019) and various reference devices, supported by:
- Compliance with recognized standards: Biocompatibility (ISO 10993-5, ISO 10993-12), sterilization validation (ANSI/AAMI/ISO 17665-1, ANSI/AAMI/ISO 17665-2, ANSI/AAMI/ISO 14937).
- Material specifications: Conformance to ASTM F136 for titanium alloy.
- Engineering analysis and design specifications: Comparison of design features to predicate devices and confirmation of compatibility through reverse engineering.
8. The sample size for the training set
Not applicable. This is not a machine learning or AI device that requires a training set.
9. How the ground truth for the training set was established
Not applicable. As above, there is no training set for this device.

Oneday Implant Abutment is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple unit restorations including; cemented retained, or overdenture restorations, and final or temporary abutment support for fixed bridgework. It is intended for delayed loading. Implants with diameters larger than 5 mm are intended to be used in the molar region.
The Oneday Implant Abutment is a material for dental surgery and is an abutment used to support and maintain prosthetic restored teeth in case of partial or total loss of teeth. It is used in combination with a fixture implanted in the jawbone.
This document describes a 510(k) premarket notification for the "Oneday Implant Abutment," a dental device. The primary purpose of a 510(k) submission is to demonstrate that a new device is "substantially equivalent" to a legally marketed predicate device, meaning it has the same intended use and the same technological characteristics, or if there are differences, those differences do not raise new questions of safety and effectiveness.
The provided text details the device description, indications for use, comparison to predicate devices, and non-clinical test data. It is crucial to understand that this document does NOT describe the acceptance criteria and a study proving a device meets those criteria in the context of clinical performance or AI/software validation. Instead, it describes mechanical, material, and biocompatibility testing for a physical dental implant component to demonstrate its substantial equivalence to an existing device.
Therefore, many of the requested items (e.g., sample size for test set, data provenance, number of experts, adjudication method, MRMC study, standalone performance, ground truth establishment for AI systems, training set sample size) are not applicable to this type of device submission. This is a traditional medical device submission, not a submission for a software-as-a-medical-device (SaMD) or an AI/ML-driven device that would involve performance metrics related to diagnostic accuracy or clinical outcomes.
Here's an analysis of the provided information relative to your request:
1. A table of acceptance criteria and the reported device performance:
The acceptance criteria here are standards for mechanical performance, biocompatibility, and sterilization, rather than performance metrics for an AI algorithm.
Test Type | Acceptance Criteria (Standard Met) | Reported Device Performance |
---|---|---|
Fatigue Testing | ISO 14801:2016 (Implies meeting the fatigue strength requirements defined by the standard for dental implants/abutments) | "The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the predicate device." Specifically, "The Fatigue Testing was performed under worst case scenario according to ISO 14801." (The exact quantitative performance is not provided in a summary table but is stated to meet the standard.) |
End User Sterilization Validation | ANSI/AAMI ST79, ISO 17665-1, ISO 17665-2, ISO 11737-1, ISO 11737-2, and ISO 11138-1 (Implies demonstrating that the proposed sterilization method effectively sterilizes the device and maintains its properties) | "The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the predicate device." "The end user sterilization test was performed on abutment that is not cleared but it can be leveraged for the subject device because the product category, material, manufacturing process, facility, and packaging of the both products are exactly same." |
Biocompatibility Testing | ISO 10993-1:2009, ISO 10993-3:2014, ISO 10993-5:2009, ISO 10993-6:2007, ISO 10993-10:2010, and ISO 10993-11:2006 (Implies demonstrating the device is safe for biological contact according to the specified parts of the ISO 10993 series) | "The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the predicate device." "The Biocompatibility Test was conducted on abutment made of Ti-6AI-4V ELI and leveraged for the subject device because both products are manufactured with same materials and manufacturing process. It demonstrates that the subject device is biocompatible and substantial equivalence with the predicate." |
Dimensional Tolerance | Within ± 1% range (for stated dimensions of various components like abutments, cylinders, etc.) | Not explicitly stated as a 'reported performance' for the device itself, but assumed to be met for the manufactured products as part of quality control and design specifications. The document lists dimensions but not measured ranges. |
2. Sample size used for the test set and the data provenance:
- Sample Size: The document does not specify exact sample sizes for the non-clinical tests (e.g., number of abutments tested for fatigue, sterilization, or biocompatibility). This information is typically detailed in the full test reports referenced in the submission, not summarized in the 510(k) summary letter.
- Data Provenance: The tests are non-clinical (laboratory-based) performed on "subject device" or "worst-case test article" samples. There is no patient data involved for these tests. The country of origin for the data generation (the testing laboratories) is not specified in this summary. These are prospective tests 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 is not applicable. The "ground truth" for mechanical testing, sterilization, and biocompatibility is based on established ISO and ANSI standards. There are no "experts" establishing a "ground truth" in the clinical imaging or diagnostic sense. The evaluations are objective measurements against predefined thresholds.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- This is not applicable. Adjudication methods are typically used in clinical studies, particularly for subjective assessments (e.g., image interpretation). These are objective non-clinical tests.
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 a physical dental implant abutment, not an AI-powered diagnostic or assistive tool. No MRMC study would be performed for this type of device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- This is not applicable. There is no algorithm or software for which standalone performance would be relevant for this physical device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- For the non-clinical tests, the "ground truth" is defined by the objective pass/fail criteria specified by the referenced ISO/ANSI standards for mechanical properties, sterility assurance levels, and biocompatibility endpoints. There is no clinical "ground truth" in the sense of pathology or outcomes data for this specific submission, as it relies on non-clinical testing for substantial equivalence.
8. The sample size for the training set:
- This is not applicable. This is a physical medical device, not a software/AI product requiring a training set for model development.
9. How the ground truth for the training set was established:
- This is not applicable. See point 8.
In summary: The provided document is a 510(k) summary for a physical medical device, the Oneday Implant Abutment. It demonstrates substantial equivalence primarily through comparisons of design, materials, intended use, and adherence to established performance standards through non-clinical (laboratory) testing. It does not involve AI/ML technology or associated validation studies typically seen in software medical device submissions, and therefore, many of the detailed questions regarding AI performance criteria and study design are not relevant to this specific document.

The OSSTEM Abutment system is intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures.
TS Abutment System is made of titanium alloy. TS Abutment System is intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures. TS Abutment System is similar to other commercially available products based on the intended use, technology used, material composition employed and performance characteristics.
The provided document is a 510(k) summary for the Osstem Implant Co., Ltd. TS Abutment System. It describes the device and claims substantial equivalence to previously cleared predicate devices. The document does not describe a study that uses acceptance criteria in the context of device performance metrics like accuracy, sensitivity, or specificity, nor does it involve expert reviews or clinical trials for such metrics.
Instead, the submission focuses on demonstrating substantial equivalence through comparisons of technical characteristics and performance testing (bench testing, biocompatibility, sterilization validation, etc.) against existing predicate devices and established standards.
Therefore, most of the requested information regarding acceptance criteria for device performance (accuracy, sensitivity), sample sizes for test sets, data provenance, number and qualifications of experts, adjudication methods, MRMC studies, standalone performance, and ground truth establishment would not be applicable to this type of regulatory submission. This submission does not pertain to an AI/ML powered device, but rather a physical dental implant component.
However, I can extract information related to the technical comparisons that demonstrate substantial equivalence.
1. A table of acceptance criteria and the reported device performance
The document does not present explicit acceptance criteria in terms of numerical performance metrics (e.g., specific thresholds for accuracy, sensitivity). Instead, the acceptance is based on demonstrating that the subject device's characteristics and performance are "substantially equivalent" to predicate devices, often by adhering to established standards or by justifying that any differences do not raise new questions of safety or effectiveness. The reported "performance" for most components is implicitly that they function equivalently to their predicates and meet relevant mechanical and biological standards.
Here's a summary of the non-clinical performance and "acceptance criteria" through comparative analysis:
Aspect | Acceptance Criteria (Implicit) | Reported Device Performance |
---|---|---|
Mechanical Properties (Fatigue) | The fatigue performance of the proposed device is considered to be equal to or greater than that of the reference/primary predicate device. This is often justified by: |
- Same design, function, connection, and platform as predicate.
- Adherence to ISO 14801 standard (maintaining 11mm distance between embedding plane and hemispherical loading member).
- Differences (e.g., added lengths or diameters) not creating a new worst-case scenario. | Rigid Abutment: No additional fatigue testing conducted, as the proposed device has the same design, function, connection, platform, and moment arm as the reference/predicate, and added lengths are within acceptable ranges or previously cleared for similar components.
Transfer Abutment: No additional fatigue testing conducted for similar reasons, justifying that changes in connection features were evaluated and not a new worst case, and that the device has the same moment arm.
Angled Abutment: No additional fatigue testing conducted, as differences in feature (guide for connecting with implant body) do not change the fundamental design or platform and the proposed device's fatigue is considered equal to or greater than the predicate.
FreeForm ST Abutment: No additional fatigue testing conducted, as added dimensions are within the range of the reference device and it maintains the same moment arm.
Temporary Abutment: No additional performance test needed as it's for temporary use, and the proposed gingiva height has primary predicate clearance.
Multi Abutment: No additional fatigue testing conducted, as added dimensions (gingival height) are covered by primary predicates and it maintains the same moment arm.
Ti Cylinder Screw: No fatigue testing considered necessary as it's a component using with cylinder, and material biocompatibility is established.
Convertible Abutment: No additional performance tests as difference is sterilization process. Its mechanical performance is expected to be equivalent to predicate. |
| Biocompatibility | The device materials must have acceptable biocompatibility, typically demonstrated by using materials already cleared in predicate devices or by following ISO 10993-1. | The TS Abutment System uses the same materials (e.g., Ti-6Al-4V (ASTM F136), Titanium Gr.3 (ASTM F67), Titanium Gr.4 (ASTM F67)), manufacturer, manufacturing process, and surface treatment as primary predicate and reference devices. Therefore, no additional biocompatibility testing was conducted. |
| Sterilization Validation | The sterilization process must be validated to ensure sterility, or justified if changes from predicates do not create a new worst-case scenario. For sterile devices, shelf-life must be validated. | For those components provided sterile, the validation of the gamma irradiation process was previously conducted for the predicate device. Changes in dimensions for the subject device do not create a new worst-case scenario for sterilization, thus no additional validation was required. Shelf-life for sterile components (e.g., Transfer Abutment, Angled Abutment, Multi Abutment, Convertible Abutment, Port Abutment, Stud Abutment, Healing Abutment) is established as 8 years. For non-sterile devices made of titanium, no specific shelf-life is considered for the material itself due to its known stability. |
| Pyrogen Test | Absence of pyrogens to meet established standards (e.g., ISO 10993-11:2006 and USP). | Bacterial Endotoxin Test Report on implants was referenced from K161604, indicating previous compliance. |
| MR Compatibility | Evaluation of magnetically induced displacement force and torque based on FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment." | Non-clinical worst-case MRI review was performed using scientific rationale and published literature (e.g., Woods et al., 2019), addressing parameters for magnetically induced displacement force and torque for all compatible implant bodies, abutments, and fixation screws and material composition. |
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: Not applicable. This submission relies on comparisons to predicate devices and existing standards, not a new test set for performance evaluation in the clinical sense (e.g., diagnostic accuracy).
- Data Provenance: The document references previously cleared 510(k) submissions (e.g., K182091, K161689, K221684, K163634, K161604, K120847) from Osstem Implant Co., Ltd. and one from Southern Implants (Pty) Ltd. The specific country of origin for the data from these predicate clearances is not detailed in this summary, but the manufacturer of the subject device is based in the Republic of Korea. The data is retrospective, as it refers to performance data and justifications from prior clearances.
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)

The LW Implant System is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations including; cemented retained, screw retained, or overdenture restorations, and terminal or intermediate abutment support for fixed bridgework. The LW Implant System is dedicated for two stage surgical procedures and is intended for delayed loading. Also, implants with diameters larger than 5mm are indicated for molar regions.
The LW Implant System consists of a fixture, cover screw, healing abutments, and abutment screw. The Fixture is made of CP Ti Grade 4(ASTM F67) with the surface treated by the SLA method. It has several design characteristics: internal hex connection, submerged type, tapered body, sided cutting edge. The Cover Screw and Healing Abutment are made of CP Ti Grade 4(ASTM F67) without any surface treatment. The Abutments consist of the LW Solid, LW Angled, LW Vis and LW Temporary Abutment, and LW Abutment Screw. The abutments have s-Line type and cuff type. The abutments are made of Ti-6AI-4V-ELI (ASTM F136).
The provided text is a 510(k) Summary for the LW Implant System. It outlines substantial equivalence to predicate devices rather than providing a detailed study report with specific acceptance criteria and performance data for this device. Therefore, a table of acceptance criteria and direct device performance is not explicitly available in the provided text in the way one would typically find for a new, de novo device or a clinical study.
The document focuses on demonstrating that the LW Implant System is "substantially equivalent" to already legally marketed predicate devices. This means that the device meets the same safety and effectiveness standards, often by showing it performs as well as, or better than, a known predicate device.
Based on the provided text, here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
As noted, the document doesn't present specific acceptance criteria and performance data in a dedicated table for the LW Implant System, as it's a 510(k) submission focused on substantial equivalence. Instead, it describes various non-clinical tests performed to demonstrate that the device meets established standards and performs comparably to predicate devices. The "acceptance criteria" are implied by adherence to relevant ISO and ASTM standards and FDA guidance documents, and the "reported device performance" is essentially that the device "met the acceptance criteria" or "demonstrated substantial equivalence."
Here's an interpretation of the implied acceptance criteria and the summary of reported performance:
Test Performed | Acceptance Criteria (Implied) | Reported Device Performance |
---|---|---|
Gamma Sterilization Validation | Compliance with ISO 11137-1, -2, -3 to achieve a Sterility Assurance Level (SAL) of 10-6. | Validated to achieve SAL of 10-6. Results prove equivalence to predicate device. |
End-User Sterilization Validation | Compliance with ISO 17665-1, -2 and FDA guidance "Reprocessing Medical Devices in Health Care Settings". | Validated. Results showed equivalence to predicate device. |
Shelf-life Test | Compliance with ASTM F1980; no degradation of device functionality over specified shelf-life. | Devices function adequately for 5 years without degradation. Demonstrated equivalence to predicate devices. |
Biocompatibility Tests (Cytotoxicity) | Compliance with ISO 10993-1, -5 and FDA Guidance. | Demonstrated biocompatibility of the material used. |
Fatigue Test (Dynamic Fatigue & Static Compression) | Compliance with ISO 14801:2016 and FDA guidance "Class II Special Controls Guidance Document". | Expected to function properly for intended use. |
Bacterial Endotoxin Testing (LAL) | Compliance with USP , USP , and FDA guidance for pyrogen limit specifications. | Met acceptance criteria. Demonstrated substantial equivalence with the predicate device. |
Surface Treatment Evaluation (SLA) | Compliance with 'Section 11 of Class II Special Controls Guidance Document'; comparable surface roughness, composition, and SEM imaging to predicate. | Demonstrated substantial equivalence through surface roughness, composition analysis, SEM imaging, and ICP analysis. |
MRI Safety Review | Compliance with FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment" for magnetically induced displacement force and torque. | Performed using scientific rationale and published literature; rationale addressed parameters. |
2. Sample Size Used for the Test Set and the Data Provenance
The document does not explicitly state the specific sample sizes for each non-clinical test performed (e.g., how many devices were subjected to fatigue testing, or how many samples for biocompatibility). It references standards like ISO and ASTM, which inherently define sample size requirements, but the exact numbers are not reported in this summary.
Data Provenance: The tests are non-clinical (laboratory-based) and were conducted to support the safety and performance of the device against established standards and predicate device comparisons. The "country of origin of the data" is not explicitly stated for each test, but the applicant, Ossvis Co., Ltd., is based in the Republic of Korea. The data is retrospective in the sense that the tests were completed before this submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
This information is not applicable to the provided document. The "ground truth" in this context is established through adherence to recognized international standards (ISO, ASTM) and national regulations (FDA guidance documents). These standards typically involve scientific and engineering principles, and the "experts" are the scientific and engineering professionals who developed these standards and those who conducted the tests in accordance with them. There is no mention of a ground truth established by a panel of clinical experts for a test set in a diagnostic or clinical performance study for this device.
4. Adjudication Method for the Test Set
This information is not applicable. Adjudication methods (like 2+1, 3+1) are typically used in clinical studies involving interpretation of results by multiple readers (e.g., radiologists, pathologists) to establish a consensus ground truth. Since the reported studies are non-clinical performance and safety tests, a human adjudication method is not used. The "adjudication" is essentially the determination of whether the device passed the specified test according to the defined acceptance criteria in the relevant standards.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
No, an MRMC comparative effectiveness study was not done. The document focuses on non-clinical performance and safety to demonstrate substantial equivalence, not on the comparative effectiveness of human readers with or without AI assistance. This device is a physical dental implant system, not an AI/software as a medical device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
No, this is not applicable. This device is a physical medical device (dental implant system), not an algorithm or software. The concept of "standalone performance" without human-in-the-loop is relevant to AI/software applications, not to this type of medical device.
7. The Type of Ground Truth Used
The "ground truth" for the non-clinical tests is based on established scientific and engineering standards and regulatory guidance limits. For example:
- Sterility: Defined by ISO 11137 with an SAL of 10-6.
- Biocompatibility: Defined by ISO 10993 standards.
- Fatigue: Defined by ISO 14801.
- Bacterial Endotoxin: Defined by USP and .
- Surface Characteristics: Defined by FDA special controls guidance for dental implants.
The comparison is also made against the performance and characteristics of legally marketed predicate devices, implying that their established safety and effectiveness serve as a practical "ground truth" for substantial equivalence.
8. The Sample Size for the Training Set
This information is not applicable. The LW Implant System is a physical medical device. The concept of a "training set" typically applies to machine learning algorithms where data is used to train a model.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable, as there is no "training set" for this physical medical device.

Dentis s-Clean Regular Abutment is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple unit restorations including; cemented retained, screw retained, or overdenture restorations, and terminal or intermediate abutment support for fixed bridgework. This system is dedicated for one and two stage surgical procedures. This system is intended for delayed loading.
Dentis s-Clean Regular Abutment is intended for use as an aid in prosthetic restoration. It consists of Abutments, components, and Abutment screws.
Here's an analysis of the provided text regarding acceptance criteria and supporting studies. It's important to note that this document is a 510(k) summary for a dental implant abutment, and as such, it focuses on demonstrating "substantial equivalence" to existing cleared devices rather than establishing novel safety and effectiveness criteria from scratch. Therefore, the "acceptance criteria" here are largely implied by the equivalence to predicate devices and adherence to relevant standards.
General Observation: The document primarily focuses on demonstrating substantial equivalence (SE) based on comparing the subject device's (Dentis s-Clean Regular Abutment) technical characteristics, materials, and intended use to various predicate and reference devices. The "performance" being evaluated is largely through compliance with international standards and leveraging prior testing on similar devices. There isn't a direct "device performance" in terms of clinical outcomes with AI assistance or human reader improvement, as this is a physical medical device (dental abutment).
1. A table of acceptance criteria and the reported device performance
Given the nature of the device (dental abutment) and the submission type (510(k) for substantial equivalence), the "acceptance criteria" are predominantly about meeting material specifications, standardized mechanical testing, and demonstrating equivalence in design and intended use to legally marketed predicate devices. The "reported device performance" is largely the successful completion of these tests or the justification for leveraging prior testing.
Acceptance Criterion (Implied by Standards & Equivalence) | Reported Device Performance |
---|---|
Mechanical Performance: |
- Resistance to fatigue under worst-case scenario. (ISO 14801:2016) | - "Fatigue Testing under the worst-case scenario according to ISO 14801:2016" was performed on the subject device and "results of the above tests have met the criteria of the standards." |
| Sterilization Efficacy (for SAVE Wide Cap): - Validation of sterilization process. (ISO 11137-1,2,3) | - "Sterilization Validation Test for SAVE Wide Cap according to ISO 11137-1.2,3" was "performed for predicate devices and leveraged for the subject device." Implied to have met criteria. |
| Shelf Life (for SAVE Wide Cap): - Confirmation of product stability over time. (ASTM F1980) | - "Shelf Life Test for SAVE Wide Cap according to ASTM F1980 referenced in K171027" was "performed for predicate devices and leveraged for the subject device." Implied to have met criteria. |
| End User Sterilization Efficacy (for Abutments): - Validation of end-user sterilization methods for various materials. (ANSI/AAMI ST79, ISO 17665-1,-2, ISO 11737-1,-2, ISO 11138-1) | - "End User Sterilization Validation Test Report for Abutments made with Ti-6Al-4V ELI according to [standards] referenced in K111364" was "performed for predicate devices and leveraged for the subject device."
- "End User Sterilization Validation Test Report for Abutments made with PEEK, POM and CP Titanium Grade 4 according to [standards]" was performed.
- All implied to have met criteria. |
| Biocompatibility: - Safety concerning biological interaction with human tissue. (ISO 10993-1:2009) | - "Biocompatibility testing for subject Abutments according to ISO 10993-1:2009 referenced in K171027, K171694, and K222913" was performed on the "predicate device and leveraged for the subject device because both products are manufactured with same materials and manufacturing process."
- "Demonstrates that the subject device is biocompatible and substantial equivalence with the predicate." |
| Design and Material Equivalence: - Comparison of dimensions, materials, and general design to predicate devices. | - Detailed comparison tables are provided for each component of the Dentis s-Clean Regular Abutment against specific predicate/reference devices, showing "same indications for use," similar or same dimensions (with differences justified as not impacting performance), and identical materials where applicable.
- Example for s-Clean Couple Abutment: "Subject Device and Primary Predicate(K171027) have same indications for use, similar sizes...material, and sterilization method. Both devices are substantial equivalent." |
| Intended Use Equivalence: - The subject device's intended use matches that of predicate devices. | - "This system has the same intended use and fundamental scientific technology as its predicate devices." The Indications for Use statement is provided and implicitly compared to predicate devices. |
| Manufacturing Process / Facility Equivalence: - For leveraged testing, assurance that processes are similar/identical. | - For leveraged end-user sterilization tests: "because the product category, material, manufacturing process, facility, and packaging of the both products are exactly same." |
2. Sample size used for the test set and the data provenance
The document specifies "Fatigue Testing under the worst-case scenario according to ISO 14801:2016" was performed on the subject device. However, it does not specify the sample size used for this specific test item.
For the other tests (Sterilization Validation, Shelf Life, End User Sterilization Validation, Biocompatibility), the data provenance is that they were "performed for predicate devices and leveraged for the subject device" or "conducted on the predicate device and leveraged."
- Sample Size: Not explicitly stated for any of the tests.
- Data Provenance: Retrospective (leveraged from previously cleared predicate/reference devices) and some prospective (Fatigue Testing on the subject device). The country of origin of the data is not specified, but the manufacturer is Dentis Co., Ltd. (Korea) and the US correspondent is Withus Group Inc. (USA). The tests were presumably conducted in facilities capable of meeting the cited international standards.
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 this type of device submission. This is a physical dental implant component, not an AI/software device that requires expert adjudication for ground truth establishment. The "ground truth" here is compliance with engineering standards and material specifications, verified through laboratory testing.
4. Adjudication method for the test set
This question is not applicable. There is no human adjudication process described for the engineering tests performed on a physical dental abutment. The outcome of the tests (e.g., fatigue strength, material composition) is objectively measured against a standard.
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 question is not applicable. This device is a physical dental abutment, not an imaging or diagnostic AI device that would involve human readers or AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This question is not applicable. This device is a physical dental abutment, not an algorithm or software.
7. The type of ground truth used
The "ground truth" for the performance of this dental abutment is based on:
- Engineering Standards and Specifications: Adherence to international standards like ISO 14801 (fatigue), ISO 11137 (sterilization), ASTM F1980 (shelf life), ISO 10993-1 (biocompatibility), and material specifications (e.g., ASTM F136 for Ti-6Al-4V ELI).
- Material Composition Analysis: Ensuring materials match specified standards (e.g., Ti-6Al-4V ELI, Pure Titanium Gr4, PEEK, POM).
- Dimensional Accuracy: Ensuring dimensions are within acceptable tolerances.
- Demonstrated Performance of Predicate Devices: Relying on the established safety and effectiveness of legally marketed predicate devices through showing substantial equivalence in design, materials, and intended use.
8. The sample size for the training set
This question is not applicable. This is a physical device, not an AI/machine learning model, so there is no "training set."
9. How the ground truth for the training set was established
This question is not applicable. Since there is no training set, there is no ground truth established for it.

IH Implant System is device made of titanium alloy indicated for in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations including; cemented retained restorations and terminal or interminal abutment support for fixed bridgework. IH Implant System is for stage surgical procedures. It is intended for delayed loading.
IH Implant System is device made of titanium alloy indicated for in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations including; cemented retained restorations and terminal or interminal abutment support for fixed bridgework. IH Implant System is for stage surgical procedures. It is intended for delayed loading. The system includes IH2 SLA Fixtures, IH Healing Abutments, IH Cement Abutments, and IH Multi-unit Abutments. The fixtures are endosseous threaded implants with a surface treatment of sand blasting and acid etching. The abutments are premanufactured and connect directly to the implant. The materials used are Pure Titanium Grade 4 (ASTMF67-06) and Titanium Alloy (ASTM F 136).
The provided text is a 510(k) Summary for the "IH Implant System." It describes the device and its claimed substantial equivalence to predicate devices, but it does not contain information about acceptance criteria for device performance or a study proving it meets those criteria, nor does it include details like sample sizes for test sets, data provenance, ground truth establishment, or multi-reader multi-case study results.
This document focuses on demonstrating that the new IH Implant System is safe and effective as existing legally marketed dental implant systems. The "Substantial Equivalence Review" section details how various components of the IH Implant System are similar to previously cleared devices.
The "Summary of non-clinical testing" section lists various types of tests performed to support substantial equivalence, such as:
- Endotoxin testing (USP and )
- Biological Evaluation (ISO 10993-1, Cytotoxicity Testing ISO 10993-5)
- Fatigue Testing (ISO 14801:2016)
- Gamma sterilization validation (ISO 11137-1 and ISO 11137-2)
- End User Sterilization Validation (ANSI/AAMI ST79, ISO 17665-2, ISO 11737-1, ISO 11737-2, ISO 11138-1 and ISO 11138-3)
- Shelf Life Test (ASTM F1140, ASTM F1929, ASTM F2096, ASTM F1980 and ISO 11607)
- Worst-case MRI review
However, it does not provide the specific acceptance criteria for these tests, nor does it report the quantitative results or performance metrics that would typically be described in the context of an "acceptance criteria and study" table. The document concludes that "The non-clinical testing results demonstrate that the subject device is substantially equivalent to the predicate devices," implying that the device passed these tests relative to the predicate, but the specific performance data is not disclosed here.
Therefore, I cannot provide the requested table and detailed information based on the provided text. The document is a regulatory submission for substantial equivalence, not a clinical or performance study report with specific acceptance criteria and detailed device performance outcomes.

The ET Abutment System are indicated for use with ET Dental Implants to provide support to prosthetic restoration such as crowns, bridges and overdentures in partially or fully edentulous patients.
The ET Abutment System are indicated for use with ET dental implants to provide support to prosthetic restoration such as crowns, bridges and overdentures in partially or fully edentulous patients. Manufactured from medical grade titanium alloy and delivered non-sterilized. The ET Abutments are available in various lengths and diameters; configurations are listed in the table below.
This document describes a 510(k) premarket notification for a medical device called the "ET Abutment System," which is an endosseous dental implant abutment. The primary purpose of a 510(k) submission is to demonstrate substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through de novo clinical trials.
Therefore, the submission does not contain information about specific "acceptance criteria" for an AI algorithm's performance, nor does it detail a study proving such a device meets these criteria in the typical sense of AI/ML performance evaluation. The "studies" referenced are non-clinical bench tests demonstrating the physical and material properties of the dental abutments are comparable to existing, legally marketed devices.
Based on the provided text, here's an analysis of the "acceptance criteria" and "proof" in the context of this 510(k) submission:
The acceptance criteria and proof fundamentally revolve around demonstrating substantial equivalence to predicate devices, not performance against a specific clinical metric for an AI algorithm.
Missing Information:
The document concerns a physical dental device (abutment system), not an AI/ML powered device. As such, the concept of "acceptance criteria" for AI performance, clinical study design for AI (sample size for test/training sets, data provenance, expert ground truth, adjudication, MRMC studies, standalone performance, etc.) are not applicable to this submission. The FDA letter confirms the device type: "Endosseous Dental Implant Abutment."
However, to address the prompt's implied need for "acceptance criteria" and "studies" as they relate to this specific device (dental abutment), I will interpret the request within the context of a 510(k) submission for a non-AI medical device.
1. Table of Acceptance Criteria and Reported Device Performance (as interpreted for a Dental Abutment System)
In a 510(k) submission for a dental abutment, "acceptance criteria" are typically defined by demonstrating that the proposed device has the same technological characteristics and similar performance to legally marketed predicate devices, or that differences do not raise new questions of safety and effectiveness. The "reported device performance" comes from non-clinical bench testing.
Acceptance Criterion (for Substantial Equivalence to Predicate) | Reported Device Performance (from Non-Clinical Testing) |
---|---|
Intended Use Equivalence: The device has the same intended use as the predicate. | The ET Abutment System is "indicated for use with ET Dental Implants to provide support to prosthetic restoration such as crowns, bridges and overdentures in partially or fully edentulous patients." This matches the intended use of the primary predicate and reference devices, e.g., "Osstem Abutment System is intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures." |
Technological Characteristics Equivalence: The device has comparable design, dimensions, materials, surface, sterilization, and packaging as the predicate. | - Design: "The ET Abutment System has the same design...as the predicate." (Explicitly stated) - Dimensions (Diameter, Length, Height, G/H): Various tables (pages 4, 5, 8, 9, 10, 11, 12, 13) compare proposed device dimensions to predicate/reference devices, showing direct matches or ranges that encompass them. E.g., ET Angled: Diameters 4.0 ~ 6.0 mm (Proposed) vs. 4.0 ~ 6.0 mm (Predicate). Heights 8.0 mm (Proposed) vs. 8.0 mm (Predicate). - Material: Primarily "Titanium alloy Ti-6Al-4V (ASTM F136)" or "Titanium CP Grade 3," and other specified materials (Nylon, Acrylonitrile & Butadiene Polymer (NBR), PolyCarbonate Polymer, Polyoxymethylene (POM), Gold alloy) are identical to those of the predicate devices. (Explicitly stated and documented in tables). - Surface: "Machine surface" across the board, matching predicates. (Explicitly stated and documented in tables). - Sterilization: "Delivered non-sterilized, Steam sterilized by user," matching predicates. "Validation was done following ISO 17665-1 [2006]... not necessary to re-test validation." - Packaging: "Housed in Tyvek-lidded blister tray; Placed in a tamper-evident outer package," matching predicates. Some also "Secured in plastic ampule." |
Performance Equivalence (Non-Clinical): Device performance is similar, and any differences do not raise new questions of safety or effectiveness. | - Biocompatibility: "Contract manufactured by the predicate device manufacturer using the same manufacturing process and same well known and well-established material as the predicate device; therefore, we reason it was not necessary to re-test biocompatibility." - Shelf Life: "Do not have a stated shelf life" and "use the same exact packaging materials, manufactured from medical grade titanium alloy which are non-mechanical, non-active materials therefore, degradation in performance characteristics is not likely." - Surface Treatment Characterization Testing: "Contractured by the predicate device manufacturer, with surfaces using the same manufacturing process, material and surface finishing as the predicate devices... No additional character testing was necessary." - Mechanical Properties (Fatigue Testing): "Fatique testing of the worst case scenario was conducted per Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Abutments." Proposed devices "were fatigue tested in accordance with ISO 14801 Dentistry - Fatique Test for Endosseous Dental Implants." This implies the proposed device met the fatigue resistance established for the predicate under this standard. - MRI Compatibility: "K221684 has cleared the contract manufacturer's support for the MRI compatibility of the ET Abutment System." A non-clinical review evaluated components in the MRI environment using scientific rationale and published literature, addressing force and torque per FDA guidance. |
No New or Increased Risk: The device does not introduce new or increased risks compared to the predicate. | "The propose devices do not pose any new or increased risk as compared to both the legally marketed predicate and reference devices." This is the ultimate conclusion sought by demonstrating equivalence in all the above categories. |
2. Sample Size Used for the Test Set and Data Provenance
Since this is a physical medical device submission and not an AI/ML algorithm:
- Sample Size for Test Set: Not applicable in the context of an AI test set. For physical device testing, the sample sizes would be determined by the relevant ISO standards (e.g., ISO 14801 for fatigue testing). These specific numbers are not detailed in the summary but are typically part of detailed test reports that support the conclusion of substantial equivalence.
- Data Provenance: The data comes from non-clinical testing (bench tests) performed to standard specifications (e.g., ISO 14801). The "ET Abutment System are contract manufactured by the predicate device manufacturer," implying the manufacturing process and potentially some historical performance data are shared or directly comparable.
- Country of Origin: Not specified for the non-clinical test data itself, but the applicant (Hiossen Inc.) is in Fairless Hills, Pennsylvania, USA. The predicate manufacturer (Osstem Implant Co., Ltd.) is generally based in South Korea, suggesting potential international collaboration or shared manufacturing data.
- Retrospective or Prospective: Not applicable in the context of patient data. The non-clinical tests would be conducted prospectively on newly manufactured devices.
3. Number of Experts Used to Establish Ground Truth and Qualifications of Experts
- This concept is not applicable as this is not an AI/ML diagnostic or image analysis device that requires expert labeling or interpretation for "ground truth." The "ground truth" here is the adherence to material specifications, dimensional tolerances, and performance under specific mechanical and biological test conditions as defined by international standards.
4. Adjudication Method for the Test Set
- This concept is not applicable as there is no "test set" in the sense of clinical cases requiring interpretation or adjudication by multiple readers/experts. Performance is based on mechanical, material, and sterilization testing against predefined standards.
5. Multi Reader Multi Case (MRMC) Comparative Effectiveness Study
- Not applicable. This type of study is for evaluating human performance with or without AI assistance, typically in image interpretation or diagnosis. This submission is for a physical dental implant component. The document explicitly states: "No clinical performance report(s) is being submitted."
6. Standalone (i.e., algorithm only without human-in-the-loop performance) Study
- Not applicable. This pertains to AI algorithm performance.
7. Type of Ground Truth Used
- The "ground truth" for this device's acceptance is based on engineering standards, material specifications, and performance data from validated non-clinical bench tests. This includes:
- ASTM (American Society for Testing and Materials) standards for materials (e.g., ASTM F136 for titanium alloy).
- ISO (International Organization for Standardization) standards for testing medical devices (e.g., ISO 14801 for fatigue testing of dental implants, ISO 17665-1 for moist heat sterilization).
- FDA guidance documents (e.g., "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Abutments," "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment").
- Direct comparison to the established characteristics and performance of the legally marketed predicate devices.
8. Sample Size for the Training Set
- Not applicable. This concept relates to AI/ML model development. There is no "training set" for a physical dental abutment. The device's design and manufacturing rely on established engineering principles and prior knowledge from the predicate device.
9. How the Ground Truth for the Training Set was Established
- Not applicable. Again, this refers to AI/ML model training. The "ground truth" for developing a physical device is derived from engineering design principles, material science, and the performance history of similar devices.

- This information is not applicable and not provided in a 510(k) summary for a dental implant system. The document focuses on physical, chemical, and biological performance testing against established standards, not on diagnostic accuracy requiring expert consensus as ground truth.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable. The tests mentioned are non-clinical, objective tests against engineering and biological standards, not requiring human adjudication of results in the way a clinical imaging study might.
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 a dental implant system, not an AI-powered diagnostic device. No MRMC studies were mentioned.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This is a dental implant system, not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
- For the non-clinical tests, the "ground truth" or reference for acceptance is primarily the criteria defined by international and national standards (e.g., ISO 10993, ISO 14801, ISO 11137, ANSI/AAMI, USP), as well as FDA guidance documents. These standards define methodologies and acceptable limits for properties like biocompatibility, fatigue strength, sterility, and packaging integrity.
8. The sample size for the training set
- Not applicable. This is a medical device (dental implant), not a machine learning model that requires a training set.
9. How the ground truth for the training set was established
- Not applicable. (See answer to #8).
Summary of Study Type:
The "studies" described are a series of non-clinical performance tests conducted to demonstrate that the physical, chemical, and biological properties of the Point implant system meet established international standards and FDA guidance for dental implants. These are largely laboratory-based tests comparing the device's performance against predefined thresholds and methodologies specified in the standards. No clinical studies (human trials) were included in this 510(k) submission.

It is intended for delayed loading.
The proposed device, IM/ST Fixture System, is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations including; cemented retained, screw retained, or overdenture restorations, and final or temporary abutment support for fixed bridgework. It is intended for delayed loading.
Implant system contain dental implant and abutment. The dental implant system, IM Implant System and ST Implant System, both of which are divided into mini implant and regular implant. IM Implant and ST Implant have different designs for the external thread section. The external thread part of IM implant is composed of conical shape, double thread and spiral groove, while The external thread part of ST implant is composed of conical shape, single thread, neck micro thread and cutting groove. Both IM implant and ST implant are available in diameters of 3.75, 4.2, 4.6 and 5.05mm and lengths of 7, 8.5, 10, 11.5, 13 and 15mm, and both are bone level. The "mini" and "regular" differ in size, but abutments are cross-compatible with both IM and ST implant types, and the abutment is attached to the implant by abutment screw and fastened to the implant. The material of abutment screw is Titanium Alloy (Ti-6A1-4V, ASTM F136).
The implants are bone level. The implants were made of Pure Titanium Grade 4 and underwent sandblasting and acid etching process. Modified surface testing (SEM/EDS) for blasted/etched surfaces was conducted to demonstrate removal of particles and chemicals from implant surface.
Abutment can be divided into healing abutment, straight abutment, multi-abutment, multi-angled abutment and temporary abutment. And it is divided into mini abutment and regular abutment. In addition, abutment also has three types of cylinder, angled cylinder and temporary cylinder.
The provided document is a 510(k) summary for the Guilin FiTeeth Medical Instrument Co., Ltd. IM/ST Fixture System. It describes the device and its comparison to predicate and reference devices to demonstrate substantial equivalence, rather than establishing acceptance criteria and proving performance against them through a clinical study with detailed metrics like sensitivity, specificity, or AUC.
Therefore, the requested information for acceptance criteria and study details cannot be extracted as the document pertains to a medical device submission for substantial equivalence based on non-clinical tests and technological characteristics comparison, not an AI/Software as a Medical Device (SaMD) performance study with specific acceptance criteria, test sets, ground truth establishment, or human-in-the-loop effect sizes.
The document states:
- "No clinical study is included in this submission." on page 6.
Instead, the submission relies on:
- Non-clinical testing: This included biocompatibility (ISO 10993-1, USP ), dynamic fatigue (ISO 14801), material specifications (ASTM F136, ASTM F67), sterilization validation (ISO 17665-1, ISO 17665-2, ISO 11137-2, ISO 11137-1), accelerated aging (ASTM F1980), and MRI safety review. These tests verify that the device meets design specifications and complies with relevant standards.
- Technological characteristics comparison: The proposed device was compared in detail to a primary predicate device (K121995, OSSTEM IMPLANT CO.,LTD TS FIXTURE SYSTEM) and several reference devices for its abutment components. Differences in structure, body diameter, implant length, shelf life, and dimensions of various abutment types were assessed, and the manufacturer argued these differences do not affect substantial equivalence based on mechanical testing, coverage by predicate/reference ranges, or biocompatibility evaluations.
Since this is a submission for a traditional medical device (dental implant system) and not an AI/SaMD, the typical acceptance criteria and study details related to AI performance (e.g., sensitivity, specificity, AUC, human reader improvement with AI assistance, independent test sets, expert ground truth adjudication) are not applicable or provided in this document.
