Intended Use

The OSSTEM Abutment system is intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures.

Device Description

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.

AI/ML Overview

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:

AspectAcceptance 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.
BiocompatibilityThe 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 ValidationThe 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 TestAbsence of pyrogens to meet established standards (e.g., ISO 10993-11:2006 and USP<151>).Bacterial Endotoxin Test Report on implants was referenced from K161604, indicating previous compliance.
MR CompatibilityEvaluation 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)

Not applicable. No "ground truth" as typically understood in AI/ML diagnostic performance studies was established or used for this device's submission. The evaluation is based on engineering principles, materials science, and conformity to recognized standards.

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

Not applicable. No adjudication method for a test set 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 is not an AI-powered device.

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

Not applicable. This is not an AI-powered device.

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

Not applicable. No "ground truth" of this nature was used. The ground truth, in a regulatory sense for this type of device, is conformity to established material specifications, manufacturing processes, and recognized performance standards (like ISO 14801 for fatigue testing).

8. The sample size for the training set

Not applicable. This is not an AI-powered device.

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

Not applicable. This is not an AI-powered device.

However, proposed device has same design, function, connection and platform as reference device. Also, primary predicate for the increased gingival height of 6mm and 7mm is already cleared in Transfer Abutment, K182091.In addition, since proposed device is straight type and the distance between the embedding plane and the centre of the hemispherical loading member always is 11mm according to the ISO 14801, it has same moment arm.As a result, the fatigue of the proposed device is considered to be equal to or greater than that of the reference device. Therefore, we don't conduct additional fatigue testing.

with same material with same manufacturing process by same manufacturer compared to thatof the primary predicate Transfer Abutment, K182091.
DifferencesThe added lengths differ from the dimension range of the primary predicate because newlength combination is added to the same diameter range as primary predicate. Also, proposeddevice differs in feature from the primary predicate because it has a guide to supportconnecting with the implant body. However, this change in connection features wasevaluated and determined that is not a new worst case for bench testing.
In addition, since proposed device is straight type and the distance between the embeddingplane and the centre of the hemispherical loading member always is 11mm according to theISO 14801, it has same moment arm.
As a result, the fatigue of the proposed device is considered to be equal to or greater than thatof the primary predicate. Therefore, we don't conduct additional fatigue testing.
.: Proposed Transfer Abutment and the primary predicate have common in design, function,indication for use, material, manufacturing process, manufacturer, etc.; therefore, theproposed device is substantially equivalent to the primary predicate.

Summary of Non-clinical Performance Testing

Non-clinical testing data were referenced by prior clearances to demonstrate substantial equivalence.

Biocompatibility Evaluation

Biocompatibility testing was considered followed the FDA Guidance Document Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process, " The TS Abutment System has same materials, manufacturer, manufacturing process, surface treatment etc., as primary predicate and reference devices. Therefore, we didn't conduct additional biocompatibility test.

Sterilization Validation and Shelf-life

Validation of the gamma irradiation process was previously conducted for the predicated device. The processes of prediates since the clearance and the change in dimensions of the subject devices do not create the new worst case scenario or sterilization; therefore, additional validation is not required. In addition, TS Abutment System are made with titanium and titanium alloy we don't consider about shelf life of material by itself because this metal is widely known that it generally has no adversely affect by aging. Therefore we certify that product such like metal has no shelf life.

Pvrogen Test

Bacterial Endotoxin Test Report on implants according to ISO 10993-11:2006 and USP<151> referenced in K161604.

Mechanical Properties

Fatigue testing was considered according to the FDA Guidance Document Guidance for Industry and FDA Staff Class II Special Controls Guidance Document Root-form Endosseous Dental Implants and Endosseous Dental Abutment and ISO 14801 standard. Processes of predicates since the clearance and the change in dimensions of the subject device do not create the new worst case scenario or bench testing.

MR Compatibility

Non-clinical worst-case MRI review was performed to evaluate the Subject device components in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry O., Jana G. Delfino, and Sunder Rajan, "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795), based on the entire system including all variations (all compatible implant bodies, abutments, and fixation screws) and material composition. Rationale addressed parameters per the FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment," including magnetically induced displacement force and torque.

7. Summary of Clinical Testing

No clinical studies are submitted.

8. Conclusion

In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807, and based on the information provided in this premarket notification. Osstem Implant Co., Ltd. concludes that TS Abutment System is substantially equivalent to the predicated devices as herein.
