No
The 510(k) summary describes a dental implant system made of titanium. There is no mention of AI, ML, image processing, or any software component that would suggest the use of such technologies. The performance studies focus on material properties and mechanical performance.
Yes
The device is described as "supporting prosthetic devices, such as artificial teeth, and to restore a patient's chewing function," which are therapeutic functions.
No
Explanation: The device is a dental implant system intended to support prosthetic devices and restore chewing function, which is a therapeutic rather than diagnostic purpose.
No
The device description explicitly states the device is made of Grade 4 titanium and consists of physical components like fixtures, screws, and abutments. It also details physical dimensions and surface treatments. There is no mention of software as a component or the primary function of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to be placed in the jaw to support prosthetic devices and restore chewing function. This is a surgical implant for a therapeutic purpose.
- Device Description: The device is a dental implant system made of titanium, designed to be surgically implanted.
- 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 treatment. The device itself is the treatment.
IVD devices are used in vitro (outside the body) to analyze samples. This device is used in vivo (inside the body) as a medical implant.
N/A
Intended Use / Indications for Use
The ST Internal Fixture System is intended to be placed in the upper or lower jaw to support prosthetic devices, such as artificial teeth, and to restore a patient's chewing function. This may be accomplished using either a two stage surgical procedure or a single stage surgical procedure.
The ST Internal Fixture System is intended for use for immediate loading when good primary stability is achieved and with appropriate occlusal loading.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A series of tests were performed to assess the proposed device is substantially equivalent to the predicate devices. All the test results demonstrate that ST Internal Fixture System meets the requirements of its pre-defined acceptance criteria and intended use.
- Sterilization Test (leveraged from own K132992 predicate)
- A Shelf Life Test (leveraged from own K052369 predicate)
- A Biocompatibility testing (leveraged from own K052369 predicate):
- Cytotoxicity Test
- Intracutaneous Reactivity Test
- Maximization Sensitization Test
- Systemic Injection Test (Intravenous Injection)
- Pyrogen Test
- 90-Day Bone Implantation Study
- Performance testing:
- Fatigue test
A fatigue test is required to evaluate the stability of implant system in oral cavity. The fatigue testing has been conducted on the proposed device in accordance with ISO 14801. Test results comply with ISO14801. It approves the proposed device is substantially equivalent to the predicate devices. - RBM surface coating
ST Internal Fixtures and the predicate devices undergo an implant surface treatment of Resorbable Blast Media (RBM). The cleaning validation test and SEM/EDX analysis have been conducted on the proposed device to verify that any particles or chemicals used to remove particles have been washed from the surface.
- Fatigue test
No additional clinical testing was necessary for a determination of substantial equivalence. The results of non-clinical testing indicated the device was found to be substantially equivalent to the predicate devices.

The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use;
(ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads;
(iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system;
(iv) The device must be demonstrated to be biocompatible;
(v) Sterility testing must demonstrate the sterility of the device;
(vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment;
(vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians;
(viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and

5.12 Similarity and differences
The differences between the proposed device and the predicate devices are the design of implant to abutment connection and accessory components. The proposed device was tested, and the results complied with the pre-defined success criteria. Therefore, the differences of proposed device and predicate devices did not raise any problems of substantial equivalence. The proposed device is substantially equivalent to the predicate devices in intended use, design, safety and performance claims.
5.13 Conclusion
After analyzing bench tests, device description and intended use/indications for use, it can be concluded that ST Internal Fixture System is substantially equivalent to the predicate devices.
