The summary describes a dental abutment system and its mechanical and material properties. There is no mention of any software, algorithms, or data processing that would suggest the use of AI/ML. The performance studies focus on biocompatibility, sterilization, mechanical properties, and MR compatibility, which are standard evaluations for this type of device.
No
The device is intended to provide support for prosthetic restorations such as crowns, bridges, or overdentures in conjunction with a dental implant, which is a structural and supportive function, not a therapeutic one.
No
The device is an abutment system intended to support dental prosthetic restorations like crowns and bridges. Its purpose is mechanical support, not to diagnose a condition.
No
The device description and performance studies clearly indicate this is a physical dental abutment system, not software. It discusses materials, manufacturing processes, biocompatibility, sterilization, mechanical properties (fatigue testing), and MR compatibility, all related to a physical implant component.
Based on the provided information, the OSSTEM Abutment System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is "intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures." This describes a device used in vivo (within the body) to support dental prosthetics.
- Device Description: The description details its compatibility with dental implant systems and its function in supporting prosthetic restorations.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
IVD devices are specifically designed to be used outside the body to analyze biological samples. The OSSTEM Abutment System is a medical device used inside the body for structural support in dental procedures.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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 Osstem Abutment System has same materials, manufacturer, manufacturing process etc., as predicate device and reference devce. Therefore, we didn't conduct additional biocompatibility test.
Sterilization Validation and Shelf-life:
Proposed devices are provided to the market in non-sterile. The proposed devices are enduser sterilized by moist heat with the same parameters as the primary predicate. The Osstem Abutment System has same materials, manufacturer, manufacturing process etc., as predicate device and reference device. Therefore, we didn't conduct additional sterilization validation.
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. First of all, gingival height of proposed TS Multi Angled Abutment is large than predicate device at the same angle. But the predicate device with the same gingival height has a larger angle. Secondly, proposed US Esthetic-low Abutment which has regular connection has bigger total length than predicate deivce. But predicate device has mini connection and total length is not affected to choose a worst case. Finally, TS Temporary Abutment has same hex size that is connected to implant although there is difference of design of hex compared with predicate device. In addition, TS Temporary Abutment is used temporarily during healing period. Therfore, we didn't conduct additional fatigue test because the proposed device is not worst-case.
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.
No clinical studies are submitted.

Differences
Proposed Esthetic-low Abutment has total length is bigger than predicated Esthetic-low Abutment. In order to consider the fatigue performance of the Esthetic-low Abutment, we take into an account whether the proposed device is chosen as a worst-case compared to predicated device.
First of all, to compare the diameter of the compatible implant fixture, we choose the MEM400 as worst case from the predicate devices since it has the smallest diameter and mini connection.
Secondly, the diameter of compatible implant fixture to the proposed device, which has regular connection, is 4.20mm and bigger than the diameter of compatible implant fixture to the predicate device, MEM400, which 3.75mm and has mini connection. Also, total length is not affected to choose a worst case because moment arm is not changed. The distance between the embedding plane and the centre of the hemispherical loading member always is 11mm according to the ISO14801.
As a result, the fatigue of the proposed device is considered to be equal to or greater than that of the predicated device. Therefore, we didn't conduct additional fatigue testing. | | |

Proposed Temporary Abutment has same design (except for its shape of hex),
function and indication for use; and is made with same material with same
manufacturing method by same manufacturer compared to that of the
predicated Temporary Abutment (K182091)
Differences
Shape of the hex between the proposed and predicated Temporary Abutment is
different. But the hex size that is connected to fixture is same although there is
difference of design of hex compared with predicated product. In addition,
since Temporary Abutment is used to make temporary prosthesis for esthetic
purpose for healing period after placement of fixture, changing the shape of
hex does not affect the any performance. Therefore, we do not need to consider
fatigue testing. | | |

: . While shape of the hex of Temporary Abutment is changed compared to the predicates, proposed Temporary Abutment and the predicated Temporary Abutment have common in design, function, indications for use, material, manufacturing process, manufacturer, etc .; therefore, the proposed Temporary Abutment is substantially equivalent to the predicated Temporary Abutment (K182091).
7. Summary of Non-clinical Performance Testing
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 Osstem Abutment System has same materials, manufacturer, manufacturing process etc., as predicate device and reference devce. Therefore, we didn't conduct additional biocompatibility test.
Sterilization Validation and Shelf-life
Proposed devices are provided to the market in non-sterile. The proposed devices are enduser sterilized by moist heat with the same parameters as the primary predicate. The Osstem Abutment System has same materials, manufacturer, manufacturing process etc., as predicate device and reference device. Therefore, we didn't conduct additional sterilization validation.
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. First of all, gingival height of proposed TS Multi Angled Abutment is large than predicate device at the same angle. But the predicate device with the same gingival height has a larger angle. Secondly, proposed US Esthetic-low Abutment which has regular connection has bigger total length than predicate deivce. But predicate device has mini connection and total length is not affected to choose a worst case. Finally, TS Temporary Abutment has same hex size that is connected to implant although there is difference of design of hex compared with predicate device. In addition, TS Temporary Abutment is used temporarily during healing period. Therfore, we didn't conduct additional fatigue test because the proposed device is not worst-case.
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
