SS Abutment System is made of titanium alloy. SS Abutment System is intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures.
The medical device described in the document is the SS Abutment System from Osstem Implant Co., Ltd. This device is an endosseous dental implant abutment, classified as Class II under regulation 21 CFR 872.3630 with product code NHA.
Here's an analysis of the acceptance criteria and the study that proves the device meets them:
1. Table of Acceptance Criteria and Reported Device Performance
The submission claims substantial equivalence to predicate devices, focusing on design, function, indications for use, material, manufacturing process, and performance characteristics. The acceptance criteria are implicitly aligned with the performance characteristics of the predicate devices, particularly regarding mechanical properties, biocompatibility, sterilization, and MR compatibility.
| Acceptance Criteria Category | Specific Criteria | Reported Device Performance |
|---|---|---|
| Mechanical Properties | Fatigue strength according to ISO 14801 standards and FDA guidance for Root-form Endosseous Dental Implants and Endosseous Dental Abutments. The criteria imply that the subject device's fatigue performance should be equal to or greater than that of the predicate devices, especially when dimensions differ (e.g., larger diameters or specific length variations that might impact stress distribution). The document explicitly mentions "not present a new worst case for performance testing." | For ComOcta Plus Abutment: Differing diameters (Ø5.5 ~ Ø7.6) and lengths (L 5, 6, 7, 7.5, 8, 9.5; L 7.5; L 5, 6, 7, 8, 8.5, 10; L 7.5; L 9.5; L 8.5; L 9.5) compared to predicate (Ø5.5 x L 6.5, 7.5, 8.5, 9.5; Ø6.5 x L 6.5, 7.5, 8.5, 9.5). Performance: "larger than predicate device, so it is considered to have equal to or greater performance than that of the predicate device." "fatigue of the proposed device is considered to be equal to or greater than that of the predicate device." Therefore, no additional fatigue testing was conducted.For ComOcta Milling Abutment: Lengths (L 14, L 14.35) not in predicate range, but diameter range is same. Performance: "fatigue of the proposed device is considered to be equal to or greater than that of the predicate device." No additional fatigue testing. Modifiability is within safe limits (min post height 4mm, gingival height 1-3mm, no angulation).For Port Abutment: Larger diameter (Ø6.06) compared to predicate (Ø4.8), same length range. Performance: "added diameter is bigger than reference device and the lengths 3.5 |
| Biocompatibility | Compliance with FDA Guidance Document Use of International Standard ISO 10993-1. The material composition of the device should be safe for biological contact. | "The SS Abutment System has same materials, manufacturer, manufacturing process etc., as predicate devices. Therefore, we didn't conduct additional biocompatibility test." |
| Sterilization Validation | Demonstrated sterility and maintenance of sterility throughout the claimed shelf-life. The sterilization process should be validated and consistent with predicate devices or established methods. | "Validation of the gamma irradiation process was previously conducted for the predicated device. There has been no change to the manufacturing or sterilization processes since then and the subject devices do not present a new worst case for sterilization validation; therefore, additional validation is not required." |
| Shelf-life | Stability and integrity of the device over its claimed shelf-life. | "SS 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." The predicate device likely had an 8-year shelf life for some components (e.g., Closing Screw), and this is maintained where applicable. |
| MR Compatibility | Safety in the Magnetic Resonance (MR) Environment, including assessment of magnetically induced displacement force and torque, per FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment." | "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." |
2. Sample size used for the test set and the data provenance
The document does not describe a traditional "test set" in the context of a clinical performance study. Instead, performance is established through non-clinical testing and comparison to predicate devices, often leveraging the fact that the subject device either has:
- Identical characteristics to a predicate.
- Dimensions that are considered to offer equivalent or superior performance (e.g., larger diameter on an implant component).
- A different intended use/loading condition (e.g., overdenture dispersing load) that mitigates concerns about increased stress from dimensional changes.
Therefore, there is no sample size for a "test set" from patients or images. The "samples" would be the configurations of the devices tested in laboratory settings (e.g., for fatigue), or the material samples for biocompatibility, or the specific device designs analyzed for MR compatibility. The document does not specify the number of units tested for any of these non-clinical evaluations, but refers to "worst-case scenarios" for mechanical testing, which implies selection of specific configurations deemed most challenging.
Data Provenance: Not applicable as no human or image data is used for performance testing. The "data" comes from laboratory physical testing, material standards, and scientific literature.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. As this is a non-clinical submission based on substantial equivalence to predicate devices and established standards (e.g., ISO, ASTM, FDA guidance), there is no "ground truth" derived from expert consensus on patient data. The "truth" is based on adherence to engineering and material science principles, and regulatory guidelines.
4. Adjudication method for the test set
Not applicable for the reasons outlined in point 3.
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 implant abutment, not an AI-powered diagnostic or assistive tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical medical device, not a software algorithm.
7. The type of ground truth used
The "ground truth" for this submission is based on:
- Standards and Guidance Documents: ISO 14801 for fatigue testing, ISO 10993-1 for biocompatibility, and FDA guidance documents for dental implants and MR compatibility.
- Material Science: Established properties of Titanium Alloy (ASTM F136), Titanium Gr 3 & 4 (ASTM F67), and POM (Polyoxymethylene).
- Existing Validations: Relying on previous biocompatibility, sterilization, and shelf-life validations performed for predicate devices with identical materials, manufacturing processes, or for which the subject device does not represent a new worst-case.
- Scientific Rationale: For MR compatibility, scientific literature and rationale are used.
8. The sample size for the training set
Not applicable. This is a physical medical device, not a machine learning model requiring a training set.
9. How the ground truth for the training set was established
Not applicable for the reasons outlined in point 8.

therefore, the proposed device is substantially equivalent to the predicate device. Summary of Non-clinical Performance Testing 7.
Non-clinical testing data are submitted 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 SS Abutment System has same materials, manufacturer, manufacturing process etc., as predicate 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. There has been no change to the manufacturing or sterilization processes since then and the subject devices do not present a new worst case for sterilization validation; therefore, additional validation is not required. In addition, SS 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.
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 with the worst case scenario. The subject devices do not provide a new worst case for fatigue testing because they are all straight.
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.
8. Summary of Clinical Testing
No clinical studies are submitted.
9. 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 SS Abutment System is substantially equivalent to the predicated devices as herein.
